other animals. We do not know positively that any bird attacks 

 them, even while young; but Mr. Lintner caught the Modest Soldier- 

 bug (^Arma modesta Dallas) in the act. This bug is congeneric with 

 and of much the same size and appearance as the Spined Soldier-bug, 

 illustrated in former reports. Of true parasites, Limneria fugitiva 

 (Say), a small Ichneumon- fly, which preys on several other insects, 

 (Rep. 4, p. 41), and an undetermined species of Microgaster, have 

 been bred from it — the latter by myself, and both by Mr. Lintner. I 

 have also noticed, in one instance, a number of Tachina eggs behind 

 the head of a larva in the third stage ; but, singularly enough, they 

 were shed with the third skin before hatching — the only case of the 

 kind that has ever come under my observation. From another larva, 

 however, I bred 7 specimens of the same Tachina-fly, which I have 

 designated anonyma., and bred from so many other larvas (Rep. 4, 

 p. 129).

This is one of our most 

 beautiful motlis, receiving 

 its name from two conspicu- 

 ous eye-spots on the hind 

 wings, in allusion to the an- 

 cient Greek heroine, lo, who, 

 as the fable went, was jeal- 

 ously guarded by the hun- 

 dred-eyed Argus. The sexes 

 differ remarkably in colora- 

 tion. The male, (Fig., 63), 

 v/hich is smaller, is also 

 much brighter colored, be- 

 ing of a deep yellow, marked, 

 as in the figure, with purple- 



brown, the body and hind wings being of a deeper ochre-yellow. In 

 the female, (Fig. 64), the purple-brown color predominates, and she is 

 somewhat differently marked. The species shows considerable varia-
