At Nonquitt, Mass., 7 June, 1889, 

 we found a nest of small, opaque, white, 

 globular eggs on a leaf of Trifolhitu 



agrariuni. These eggs were exactly 

 like some received the same day from 

 Miss Morton, and laid by a 9 Spilosotua 

 congrna. We found several moths of 

 i'. co?ig-rt(a^ flying i" Nonquitt this 

 year. 



We watched the larvae through all 

 their moults, comparing the two sets 

 daily, and they proved the same through- 

 out. 



The eggs turned lead-colored the day 

 before they hatched. They hatched 9 

 June. The young larvae were 4 mm. 

 long, with black heads. 



Body yellowish, with darl< wai'ts, 

 from which sprung gray or black hairs. 

 Anal shield dark. Feet and props like 

 body. 



They ate clover, but much preferred 

 plantain even to the Trifollum agra- 

 ri?(f/i on which the eggs were laid. 



When touched they curled up and 

 dropped from the leaf, like the other 

 •'woolly bears."

 Head black. Body-color yellow, with 

 black transverse dorsal lines between 

 the segments ; third and tenth segments

 body. Warts dark, with sparse black- 

 ish or dark gray hairs.

 disappeared and the color on and

 yellow. 



18 June. Second moult. Head 

 black. Body color deeper and browner 

 yellow ; warts darker, with hairs longer 

 and more numerous.
