falls to the surface on which the host rests, and having no method 

 of locomotion, begins to spin its cocoon where it chances to fall. 

 This it can do as well lying on its side as when standing on end; 

 only in the former case it passes the head from side to side, over 

 the body, instead of up and down, as when perpendicular. 



As to the time occupied in the various stages from five to eight 

 minutes elapse after the worm is first discovered beneath the skin 

 until the small rounded head is seen above the surface of the skin. 

 Not far from ten minutes are consumed in fully freeing the body, 

 while the cocoon spinning goes on visibly for at least half an hour, 

 and probably continues twice to four times as long in the privacy 

 of its own chamber. 



The first crop, the one upon the pupa when captured, hatched 

 in about one week from the time it was taken. The second crop 

 began to hatch on the tenth day from the time they first appeared. 



Unfortunately, all the perfect insects of the first lot were lost; 

 they were wholly black. Of the second lot some specimens ac- 

 company this paper. They all had yellowish legs, being con- 

 spicuously distinguished by these from the first to appear. 



The first crop consisted of twenty-five to thirty-five cocoons; 

 the second of upwards of fifty. It is worthy of remark that no 

 visible mark or injury could be found under the glass at the points 

 where the worms emerged from the surface of their host.

TERIAS NICIPPE ON LONG ISLAND. 



By RICHARD E. KUNZE, M.D. 



On Sunday morning, August 2d, this year, a rainy and threat- 

 ening kind of a day, I started off with a small Catocala net, ovoid 

 in shape and only 5x8 inches in respective diameters. A friend 

 of entomological aspiration whom I met, went with me. After 

 spending two hours inspecting many trees of Long Island City 

 in vain, we started off in another direction, which brought us to 

 the edge of a swamp and low meadows, the water of which 

 empties directly into the East River. By this time the sun came 

 out hot. I suggested to take in the swamp, part of which was 

 good cow pasture with a solitary thistle Cnicum pumilnm here 

 and there on rising ground. On thistles I took a few Papilio 

 asterias and troilus, also sometimes thysbe. Lower down as far
