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. Philampelus achemon Dru. — Larvae very common on Ani- 

 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 caroliyia Linn. — Occasionally at light (Denver). 



13. Sphinx drupiferarum S. & A. — Very common at light all 

 over the State; the large form (van utahensis H. Edw.) frequently 

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



14. Sphinx perelegmis Hy. Edw. — Uncommon at light in 

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

 fornia specimens. 



15. Sphinx vashti 'i\x^c\i^x . — 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)^ inches to 3^^ inches in extent. I 

 am not surprised that it has received several names. 



16. Sphinx gordius 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 hcscitiosa. 



17. Sphi7ix 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. 



18. 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 coloradus 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 kS. Dollii 

 Neum. may be a small form of this species.
