136 FIFTH ANNUAL REPORT 



somewhat lighter colored, lacking the plaited edges on the sutures 

 described in that species, and having the hind side of the deep mobile 

 sutures longitudinally and broadly striate or carinate, instead of 

 transversely aciculate. There are some sparse, rust-colored, curled 

 bristles on the abdominal joints, and the anal tubercle terminates in 

 quite a bunch of them. 



The moths frequently issue in the fall of the year, and some as 

 early as the middle of September; in which case it is not known 

 whether they or their eggs hibernate. They more often issue, how- 

 ever, during the following May. Unlike the exceptional liaia, they 

 are doubtless nocturnal, as I have never seen them flying during the 

 day-time. 



FOOD PLANTS. 



The species is a very general feeder. I have found it myself on 

 the so-called false Indigos {Ainorpha fruticosa and Baptisia^ two 

 species), on Sassafras, Black locust, Indian corn, wild Black cherry 

 {Primus serotioia), and Willows. It has likewise been found on Elm, 

 Hop vine. Balsam, Poplar, Balm of Gilead, Dogwood, Choke cherry, 

 Currant, Cotton and Clover.* I have also taken the full grown larva 

 from Ironweed ( Vernonia), but without any other proof that it feeds 

 upon this plant. 



PARASITES. 



Parasitized larvae are frequently met with, and the white cocoons 

 intermingled with their spines, and of which I have reared great num- 

 bers, produce the same species of llicr'Offasier, already referred to as 

 parasitic on Maia. The Long-tailed Ophion (4th Rep., Fig 37) also 

 breeds within it.
