[1891. ENTOMOLOGICAL NEWS. 



day and night; I have found it on the mountain tops at 14,000 

 feet elevation, the larvae sometimes occurring by thousands on 

 low plants near north Denver in boggy places. 



8. Chcerocampa tersa Linn. One example only, found on a 

 window in the Union Depot, Denver, probably attracted by light. 



9. Philampehis achemon Dru. Larvae very common on Am- 

 pelopsis and Grape from Denver City to about 7500 in the Canons; 

 the moth occasionally at light. 



10. Dilophonota ello Linn. Not rare at light from Denver to 

 Utah, all I have taken in Colorado are rather light colored. 



11. Protoparce celeus Burm. Common all over the State, ap- 

 parently getting more abundant every year, June and September, 

 probably a part of the larva give moths the same season. 



12. Protoparce Carolina Linn. Occasionally at light (Denver). 



13. Sphinx drupiferamm S. & A. Very common at light all 

 over the State; the large form (var. utahensis H. Edw.) irequently 

 in central and western Colorado; larvae common on wild plum. 



14. Sphinx perelegans Hy. Edw. Uncommon at light in 

 central and western Colorado; my examples are larger than Cali- 

 fornia specimens. 



15. Sphinx vashti Strecker. Not rare; I have taken it wher- 

 ever I have collected in the State east or west; varies in size and 

 color. I have them from 2^2 inches to 3^3 inches in extent. I 

 am not surprised that it has received several names. 



1 6. Sphinx gordiiis Cram. Not rare in central and western 

 Colorado. I have never taken it near Denver; Colorado exam- 

 ples are very large (I have some extending four inches) and show 

 the soft warm color of luscitiosa. 



17. Sphinx luscitiosa. Not very rare; at light and over flowers 

 in the evening in Denver City. I have also taken it flying by 

 day over flowers. 



1 8. Sphinx oreodaphne Edw. Common in central Colorado. 

 Mr. Hy. Edwards saw several of my examples and identified 

 them as the form he had so named; the Colorado specimens are 

 a clear gray, with fine markings, and extend 3^ to 3^ inches. 

 I have seen nothing in Colorado like the eastern chersis. 



19. Sphinx coloradiis Smith. Not very rare in western Colo- 

 rado. I have beaten it from Cedars and taken it at light. It is so 

 variable in size and distinctness of markings that I think S. Do/Hi 

 Neum. may be a small form of this species.
