ENTOMOLOGY OF COLORADO. 329 



147. Buprestis nuttalli Kirby, Willow Creek, Ciisack Ranch. N. to Canada. 



148. " maculiventris Say, Ciisack Ranch (M. E. Cusack). N. to Can. 



149. Melanophila long-ipes Say, common. 



150. Agrilus torpidus Lee. 



C. virginiensis is stated by Dr. Hamilton to be hardly or not specifically 

 distinct from C. mariana of Europe. 31. longipes is European and 

 Asiatic— in short, circumpolar. 



LAMPYRID^. 



151. Eros aurora Hbst. 



152. EUychnia corrusca L., West Cliff, May 25. N. to Canada. 



153. Pyropyga fenestralis Melsh., Ula, July 30. 



154. Pyractomena borealis Rand., West Cliff, May 26 ; Cusack Ranch, June 18. 



155. Chauliog-nattius basalis Lee, Beddoes' Old Ranch, Aug. 9. "Abundant 



near Fort Bridger and in the Black Hills" (LeConte). 



156. Podabrus lateralis Lee. Also high-alpine. N. to Laggan, Alberta (Bean). 



157. Silis tnunita Lee. 



1.58. " difflcilis Lee. E. New Mexico (LeConte). 



159. Telephorus sp., West Cliff, July 27. 



Eros aurora is circumpolar. It is interesting to note that near Iowa City, 

 although Mr. Wickham records species of Pyropyga, Pyractomena, 

 Chauliognathus, Podabrus and Silis, none of them are the same as ours. 

 A. species of Chauliognathus is fossil at Florissant. 



MALACHIID^. 

 IfiO. Collops vittatus Say, var. (or u. sp. ?), West Clifif, July 26. C. vittatus 

 occurs in Canada. 



161. Malachius montanus Lee. 



162. Listrus senilis Lee, West Cliff, July 27; Beddoes' Old Ranch, Aug. 9. 



In Mr. Wickhani's Iowa City list are three genera of this family; only 

 one, Callops, is the same as ours, and then the species is different. 

 Another lowa'City genus, Attains, was found by Mr. Wickham in the 

 subalpine at Canon City, the species being A. basalis. 



CLERIDJE. 



163. Trichodes ornatus Say, very common ; June 3, on flowers of Ligusticum 



montanum ; July 19, on Geranium fremontii ; July 20, on Achillea; one 

 on a flower of Rosa blanda. and many on yellow flowers, June 26. 



164. Clerus sphegeus Fab., West Cliff, May 24 (Mrs. Chetelat). N. to B. Col. 



165. Necrobia violacea L., very common. Specimens of what must have been 



this, I have formerly called Corynetes coerideus, one having been so 

 named for me. 



N. violacea is circumpolar. T. ornatus goes north to Laggan. Alberta (T. 

 E. Bean in litt.) ; southward, LeConte quotes it from E. N. Mexico. 



Trichodes ornatus, as observed by me in our district, is constant in color, 

 with yellow markings and the thorax blue. This is quite the same 

 as T. hartwegianus White, the type of which I saw in the British Mu- 

 seum. Spinola's description of ornatus agrees with this form, but his 

 figure shows the yellow less developed. T. douglasianus White from 

 California, is a distinct form, both as to color and markings; the tho-
