Palaearctic Acrididae new to the Indian Fauna

The present paper includes notes on several Acrididae of definite Palaearctic affinities not previously reported from India, two of them new to science but belonging to a purely Palaearctic genus. It will be seen that the series comprises not only the Mediterranean faunistic elements (Oedipoda, Calliptamus), and those of the so.uthern Palaearctic steppes (Dociostaurus), but also much more northerly ones such as Chorthip pus and even Gomphocerus sibiricus, which is typical of the northernmost steppes and of the high mountains of Europe.Peer reviewe

The genus Hilethera Uv. and its species (Orth. Acrid.)

3 láminas.The genus Hilethera has been founded by me in 1923 1 to include a very peculiar new grasshopper from Palestine named H. hierichonica Uy. To the same genus I have referred at the time an Arabian species described by me the year before as Lerina aeolopoides Uy. and at present I have before me two more new species, one from Turkestan, another from Sudan which also belong to Hilethera. Since I am inclined now to include in Hilethera also Lerina buxtoni U y. which in 1923 I thought to fit better into Aiolopus, the genus Hilethera consists of five well defined species, and I feel bound to present some remarks on the characteres and relationship of the genus and its species, as well as to give a key to species.Peer reviewe

Orthoptera Palaearctica Critica: VIII. A preliminary revision of the genus Aeropus Gistl. (Gomphocerus auct. partim) (Acrid.)

The type of the genus Gomphocerus Thnbg. has been fixed by Samouelle in 1819 (Entom. Useful Conzpendium, p. 219) as rufus Thnbg., and the fixation was formally confirmed by Kirby in 1910 (Syn. Cat. Orth., III, p. 154).Peer reviewe

Orthoptera collected by M. Sureya Bey in Turkey

My colleague M. Sureya Bey, of Angora, was very kind to collect at my request some Orthoptera in various provinces of Turkey, and the collection proved to be of great interest owing to an unexpectedly high percentage of species new to science. Since the distribution of Orthoptera in Asia Minor is still imperfectly known, I thought it useful to publish not merely descriptions of new species, but a full list of the collection.Peer reviewe

Orthoptera palaearctica critica: II. Genus Tropidopola St. (Acrid.)

The first species of Tropidopola vas described by Marschall in 1836 under the name Gryllus cylindricus from Sicily. Three years later Serville (1839) described in his g-enus Opsomala an O. sicula from Sardinia, which also belongs to Tropidopola; another species O. pisciformis, described by Serville in the same book fi-om Java and Egypt and regarded by some later authors as synonymous with cylindrica, has nothing to do with the genus since it is stated to have «disque du prothorax... distinctement tricaréné»; it is possible that the specimen fi-om Egypt which Serville mentions under pisciformis was actually a Tropidopola, but the description was obviously based on the specimen fi-om Java.Peer reviewe

A revision of the group Mesopsis (Orthoptera, Acrididae)

The genus Mesopsis I. Bolivar is usually referred to the subfamily Catantopinae, because of the presence of a prosternal tubercle. This, however, is not an absolute character, since the tubercle is absent in some members of Catantopinae, and present in some genera of other subfamilies. On the other hand, the specialised elytral venation in the male of Mesopsis and the presence of the stridulatory pegs on the inner side of its hind femur are definite characters not of the Catantopinae, but of the Acridinae. In fact, Mesopsis is clearly related to Brachycrotaphus Krauss, which has been originally described as a member of Catantopinae. but is an unquestionable Acridine. The Acridine affinities of Mesopsis have been recently confirmed by Slifer on anatomical grounds (Journ. Morph., vol. 65, 1939, pp. 444, 447).Peer reviewe

New or less known Acrididae from Central Asia

About three years ago I undertook, on the suggestion of my friend V. I. Plotnikov, Director of the Central-Asian Station for Plant Protection in Tashkent, a general survey of the Acrididae of Central Asia, with a view of publishing a handbook for their identification and study. As a basis of this work served collections sent to me by Mr. Plotnikov, which proved to contain a number of undescribed species, or such as have been only very inadequately described by previous authors. A re-examination of Central-Asian specimens of other species, recorded from the country before, showed that in a number of cases they have been referred to known species incorrectly, being either distinct specifically, or belonging to well distinct geographical races. While the book on the Acrididae of Central Asia, containing keys, descriptions and figures, is hoped to be published in Russian shortly, I thought it imperative that all descriptions of new forms and notes of systematic and synonymic value should be published separately and in a more widely known language and the present paper is one of the series written to this end.Peer reviewe

Orthoptera Palaearctica critica: VI. Genus Bergiola Stschelk. (Tettig.)

Stschelkanovzeff described in 1907 (see bibliography at the end) a new genus of Decticinae allied to Paradrymadusa Herrn., which he called Bergiella, but this name proved to be preoccupied and in 1910 he renamed the genus Bergiola, publishing a German literal traslation of the original description (it was mainly in Russian) and a photograph.Peer reviewe
