in May and June and again in July and August. It is closely 

 allied to H. thysbe var. ruficaudis, but differs therefrom by its 

 smaller size and by having a red stripe on each side of the 

 thorax beneath, and three rows of white spots on the under side 

 of the abdomen. It flies during the day in the sunshine. 



5. Hemaris diffints. 



In the immediate vicinity of New York this species is very 

 rare. It is found from Canada to Florida, and westward to Mis- 

 souri and Iowa. In certain localities it is rather common. Found 

 during the latter part of May and early in June and again during 

 July and August. It flies during the day in the sunshine. The 

 caterpillar feeds on snowberry (Symphoricarpus) , feverwort 

 (Triosteum perfoliatum) and bush -honeysuckle. Forms a pupa 

 on the ground in a loose cocoon. 



Hemaris axillaris. 



Very rare in this vicinity, but more abundant in the Western 

 States. It is found from New York to Texas. In general ap- 

 pearance it resembles H. diffints, but the outer border of the fore 

 wing is broader, and is more or less toothed inwardly, while in 

 diffints it is even. The body is longer. The moth flies during 

 the day in the sunshine. The caterpillar feeds on different 

 kinds of honeysuckle. Forms a pupa in a loose cocoon on the 

 ground.
