Agaristidae 



on the under side of the purslane leaf, either singly or in clusters 

 of from *wo to five. The larva hatches in two or three days, and 



is at first light green or yellowish 

 green with darker shading across 

 the middle of the body. In eight 

 or nine days it attains full growth 

 after having passed through four 

 molts. The full grown larva is 

 light gray or dull white with black 

 dashes on the sides of each seg- 

 ment, and with the shadings of 

 salmon pink." 



"The full-grown larvae enter 

 the ground for pupation, excavat- 

 ing a tubular burrow in the sur- 

 face soil, gumming the lining 

 and closing the opening v/ith a 

 thin layer of particles of soil. . . . The insect remains in 

 this state in the neighborhood of twelve days." 



In the accompanying figures we show the egg, the pupa, 

 and the adult larva and moth. The insect is very abundant 

 at certain times in Nebraska, 

 Kansas, and the southwestern 

 States generally, and ranges into 

 northern Mexico. It appears 

 to feed exclusively upon purs- 

 lane, and as this plant is of no 

 particular economic value, but 

 is justly accounted as a trouble- 

 some weed, we may wish bless- 

 ings upon Copidryas gloveri.

This pretty insect, which 

 belongs to the same genus as 

 the preceding, though assigned 



by the author of the species to the genus Euthisanotia, is found 

 in Arizona and in Mexico. Its habits are undoubtedly very much
