During the past few years I have received from a number of different sources, partly by purchase and partly by sets sent me for determination, a number of collections of Hemiptera, and as some of these records extend the known distribution of the species, or give more specific data regarding them, it seems desirable to give them a permanent record

It is probable that if this particular skull were placed in the hands of Dr. Gray he wonld consider the "inca" bone enormously developed wormian bones. lt seems to me, how-ever, that there is a more natural explanation and one more in accord with the facts. I have here the tabular portion of the occipital cf a well ad rnnced human fffitus. It is what would correspond to the supraoccipital of some of the lower mammalia. The bone is cleft on each side, the fissure being just above what will ultimately be the superior curved line. Looking on the inside of the bone, there are indications that at a still earlier stage of development this bone was separated into two parts, the separation being along a line a little abo1'e the superior curved line. This is exactly the condition of affairs fonnd in the skulls with the "inca" bone. In other words, we have in the ordinary human embryo a condition of affairs which we find in the adult skulls of these prehistoric people. It seems likely, therefore, that we have here a persistent embryonic character. Unfortunately I was unable to find any satisfactory record of these skulls in the catalogue of the Academy. Most of them were simply entered by number. One was marked "De Kalb Co., 111.," and I was told that it and several others came from prehiotoric gra1·es in that locality. If the "inca bone" was a characteristic of a definite race of human beings, it would certainly be sufficient to constitute a new species of the Genus Homo. If it was only au occasional, or even somewhat frequent abnorm-ality, it may be regarded simply as a "reversion" indicating that the race possessing it was of a peculiarly low type. NOTES ON THE DISfRIBUTlON OF HEi\lIPTERA. BY HERBERT OSBORN. During the past few years I have received from a number of different sources, partly by purchase and partly by sets sent me for determination, a number of collections of Hemiptera, and as some of these records exteud the known distribution of the species, or give more specific data regarding them, it seems desirable to give them a permanent record. The principal collections on which the paper is based, aside from my own, are those made by Mr. Wickham in New Mexico, Arizona and Cali-fornia, and in the northwest, and purchased by the Agricultural College or by myself, those from Prof. C. P. Gillette, of Colorado, Prof. Lawrence Bruner in Nebraska, Prof. V. L. Kellogg in Kansas, Dr. C. i\1. "'eed in New Hampshire, and others. The Hemiptera present us with a number of interesting cases of distri-bution. ln some cases apparently dependent upon food plant, in others 1Osborn: Notes on the Distribution of HemipteraPublished by UNI ScholarWorks, 1893IOWA ACADEMY UF SCIENCES. 121 upon climate or temperature, but in some independent of any apparent condition. With some of the species it may be an endless task to determine the conditions which most affect their geographical distribution, and in such cases it is probably a combination of influences and no single one that determines their range. Some of these notes were presented in a paper, abstract of which appears in part I, page 64, the full paper never having been published. Since the presentation of that paper, however, I have examined a number of col-lections and much increased the list of species mentioned, as well as the number of localities recorded. Eurygaster alternatus Say. Mass., Iowa; \Vyoming; Huntington, Oregon. Coeur d'Alene, Idaho; N. H. Corimelcena atra Am. et Serv. Colorado. Corimelcena albipennis Say. Colorado. Probably rare. Seems not to have been recognizect since Say's description till a specimen came into my hands from Prof. Gillette. Pangaeus bilinentus Say. Dallas, Oregon. Amnestus spinifrons Say. Colorado. Perillus splendidus Uhl. Colorado. Perillus exaptus Say. Winnipeg. Perillus claudus Say. Albuquerque, New Mexico; var. Huntington, Oregon; var. c Say. Colorado. Podisus cyniws Say. Ill., Tenn., Tex., Colorado. Podisus placiclus Uhl. Colorado. Poclisus spinosus Dallas. Williams, Ariz. Liotropis humeralis Colorado. Specimens from that state are larger than those collected in Iowa. Prionosorna zloclopoirles Uhl. Colorado and southwest. Porlops clubius Pal Beatff. Colorado. The specimens from Colorado seem to agree better with du bi us than with cinctipes which is credited to the United States, while dubius is given in Uhler's check list as belonging to the West Indies. Brochymena annulrita Fab. Colorado. Cosrnopepla carnifex Fab. :N'ew Hampshire. Cosrnopepla conspicillaris Dallas. Colorado; Vancournr Island. Morrnidea luuens Fab. New Hampshire. Euschistusjissilis Uhl. Colorado; Tacoma, \\'ash. Euschist1)s tristigrnus Say. Colorado; New Hamphire. Euschistus impinctiventri.s Stal. Portland, Oregon. Euschistus variolarius Pal Beauv. Albuquerque, New :l\Iexico; Colo. Lioderma ligata Say. Seligman and iVilliams, Arizona. Lioderma sriyi Stal. Seligman, Arizona. Peribalus lirnbolrtrius Stal. Albuquerque, New Mexico; Colorado. Thyanta rugulosa Say. iVinslow, Arizona; NcedleR, California. Thyanta custator Fab. Colorado. Thyonta perditor Fab. S. Dakota. JJfurgantia histrionica Hahn. Barstow, San Diego, Cal.; Albuquerque, New Mexico. This species is distributed very generally ov.:,r the southern portion of the country extending from New Jersey ou the east to southern California on the west. It was at one time feared it would o,·errun the 2Proceedings of the Iowa Academy of Science, Vol. 1 [1893], No. 4, Art. 41https://scholarworks.uni.edu/pias/vol1/iss4/41122 IOWA ACADEMY OF SCIENCES. northern states, and Prof. Riley some twenty years ago and other writers more recently have predicted such a danger but it would surely have as good an opportunity in the Mississippi valley as anywhere and the fact that it has made no adnwce to speak of in the last twenty-five or thirty years seems good evidence that it has a pretty definite southern limit. It will doubtless remain a serious pest to crnciferous plants through all the south-ern region and may be expected to become a pest in all settled localities in the south west port; on of the country. Chariesterus antennator Fab. Colorado. Leptoglos.ms dnctus H. Shaf. (?) Colorado. Anasa tristis De Greer. Al buq uerq ue, New Mexico. This familiar east-ern pest is generally distributed onr the southwestern country and will doubtless prove <i pest in those regions. I have seen it in destructive num-bers in central Kansas. Alyllits conspersus Montandon. New Hampshire; Iowa. This form has been confused with the European calcaratus from which Montandon has separated it under the above name and has stated its occurrence in Michigan; Burlington, Iowa; Massachusetts, Colorado and Dakota. It is generally smaller and lighter colored than eurinus Say, but specimens can be picked out of any large series which approach that species in size and markings and the two seem to me to be quite closely relateu, though I believe Mont-andon is correct in distinguishing them. Alyllus pluto Uhl. ( ?) This is a large black form, but if my specimens are good examples it might be considered an extreme form of eurinus larger and blacker than the anrnge forms. Scolopocerus sccundarius Uhl. Colorado. Jalysits spinosus Say. Albuquerque, New Mexico; San Diego, California; San Bernardino, California. Nysius thymi. New Hampshire. Nysius Angustatus Uhl. Colorado. This species is widely distributed and somewhat variable. It approaches thymi in northeastern part of the country and calijornicus of the southwest, and it seems to me to present a very close relationship to the senicionis of Europe.
