it is also destroyed by the wood pcwce (Contopus virens) and the 

 niglit hawk (Chordeiles virginianus), as he lias taken large numbers both 

 of the larva and imago from their stomachs. 



Desiderata. Although so common an insect, our knowledge of its his- 

 tory is far from perfect. The two or three records of its excessively early 

 appearance remain unexplained. AVe do not know whether it ever hiber- 

 nates in the larval condition, and if it does whether such hibernation is con- 

 fined to localities where it is triple brooded ; the line of demarcation between 

 the double and triple brooded stations needs to be carefully traced, and this 

 limit will most probably be of considerable importance for lepidopterologi- 

 cal life in general ; western Massachusetts, the southern half of New 

 Hampshire and Vermont and Maine, south of Portland, should be espe- 

 cially studied. The duration of the egg and chrysalis for each brood 

 needs to be established by abundant observations in the north and south. 

 Doubtless other parasites may be found.

 Was formed of the wings of butterflies.

Soon spreads the dismal shade 

 Of mystery over his head ; 

 And the caterpillar and fly 

 Feed on the mystery.

Imago (55 : II). Head moderately large, densely clothed with scales and profusely 

 covered wth rather short curving hairs, bending forward above and downward on 

 the face. Front flat, excepting that it is very slightly full down the middle and a very 

 little protuberant below, the lower half projecting slightly beyond the front of the 

 eyes; half as high again as broad, scarcely so broad as the eyes on a front view, the 

 sides straight; upper border scarcely ridged, the corners a little hollowed iu front of 

 the antennae ; lower border very broadly rounded. Vertex slightly hollowed In the 

 very centre, with a slight sulcation running from the middle of the hinder border to 

 each antenna and a rather abrupt, not very large, tuberculate buttress behind each 

 autenna; separated from the occiput by a rather large aud deep, slightly zigzag chan-
