56.52(78.8)Article XXV.- SOME COLEOPTERA AND ARACHNIDA FROMFLORISSANT, COLORADO.BY T. D. A. COCKERELL.On previous occasions (cf. Bull. Am. Mus. Nat. Hist., XXII, p. 420)attention has been called to the fact that Florissant, notwithstanding itshigh altitude (about 8000 ft.), is rich in austral elements. It must be con-sidered to belong to the upper part of the Transition Zone rather than to theCanadian. In 1906 I was able to collect small series of beetles and spiders,which have been very kindly determined by Messrs. H. C. Fall and N. Banksrespectively; and it is thought worth while to present the lists herewith,owing to their bearing on the zonal position of Florissant. I have givenparticulars of the distribution elsewhere in the State of most of the species,and it will be seen at once that the great majority reach the edge of the plains,-that is, go practically to the lower limit of the Transition, as at FortCollins, Denver, Colorado Springs, etc. Some, while ranging downwardsto Buena Vista, etc., seem, like the plant Hymenoxy8, to belong to the westside of the front range in the latitude of Florissant.The asterisks before the names of the families and genera indicate thatthese have been found fossil in the shales.COLEOPTERA,*CARABIDA3.*Bembidium bifossulatum Lec.

In galls (shallow subcircular cavities with thickened hairs)on leaves of Populus tremuloides. Mr. Banks says the galls and mites agree withthis European species, but he has no European specimens of the mites.Three Diptera new to Colorado were determined by Mr. Coquillett;Tersesthes torrens. Townsend, from Lake George June 18; and Scatopsenotata L. and Psilocephala munda Loew, from Florissant. The bug Dicy-phus californicus Stal was taken at Florissant July 3, and determined byM. Heidemann. The Coccid Erium lichtensioides (Ckll.) was common onArtemisia.
