 {Lappa officinalis), thistle {Circium lanceolatimt), red clover {Tri- 

 foliuiii partense), ragweed {Ambrosia artemisia; folia), smart weed 

 {Polygonum poisylvanicuni) and knotgrass {P. aviculare) and have 

 found it on burr oak, poplar, hazel {Corylns ainericana), sumac 

 {Rhus glabra), wild raspberry {Rnbus strigosus) wild blackberry 

 {R. villosus), horse radish, wild sunflower {HeliantJius grosse- 

 serratus) and blue vervain {Verbena hastata) ; and Dr, Packard has 

 found it upon Betiila populifolia,^ making in all twenty-four differ- 

 ent species of plants. It remains in the chrysalis state from five 

 to eleven days, and two broods are produced in one season. (F.) 



Penthina nimbatana. Clem. 



Body green; spiracles and piliferous spots concolorous ; 

 head and cervical shield polished black ; anal plate unmarked ; 

 length 15 mm. Lives in a folded leaf on Rosa blanda. Two were 

 taken the first week in June ; they pupated a few days later and 

 the imagos issued June 20 and 21. (F.) 



Boris osciTALis. Grote. 



Body green; piliferous spots concolorous; spiracles ringed 

 with pale brown ; cervical shield green, edged at the sides and 

 behind with black, that on the sides sometimes wanting ; head 

 mottled black and white ; anal plate unmarked ; length 16 mm. 

 Lives in a folded leaf, or between two leaves folded together 

 with silken threads, on willow and poplar. Found several in the 

 latter part of July and again about the middle of August ; one 

 pupated July 27 and the imago issued about August 8. (For the 

 generic determination of the imago I am indebted to Mr. Grote; 

 the [single] specimen bred by me agrees very well with his 

 description oi oscitalis [Can. Ent., Vol. XIL, p. 36], and as one 

 of his specimens was from Ohio it is not improbable that the 

 species ranges westward as far as Illinois). 



BOTIS GENEROSA. G. and R. 



Body green; piliferous spots and spiracles black; above the 

 spiracles is a black stripe on which is a row of large, raised, 

 polished black spots, those on the segments two and three the 

 largest ; head and cervical shield greyish-brown, the latter edged 

 each side with black; anal plate unmarked; length lO mm. 

 Lives singly on Monarda fistiilosa, webbing the terminal leaves 

 together. One found June 17 pupated June 30, and the imago 

 issued July 18. (G.) 



Penthina hebesana. Walker. 



Body green ; pilifergus spots and spiracles concolorous ; head 

 and cervical shield polished brownish-black ; anal plate unmarked ; 

 length 1 1 mm. Lives singly on Stachys palustris, binding the 

 terminal leaflets together. Found many larvae and two pupae 

 June 24. One imago issued June 30. (In the Amer. Ent. Vol.
