BY WM. EEUTENMULLER, NEW YORK. 



Chionobas Macounii, Edw. 



P'.GG. — White, subglobose, slightly flattened above and below, with 

 about seventeen longitudinal ridges, which are connected by numerous 

 fine transverse ridges. Length, about 1.2 m.m. Width, about i m. 

 Laid July 11. Emerged July 27. 



Young Larva. — Head whitish, globose, rather large, finely punctured, 

 mouth parts black. Body above bright pink, with a series of four whitish 

 longitudinal stripes on each side ; those on the dorsal region are very 

 broad, with the intervening spaces very narrow. The lateral stripe very 

 fine, and the one below the spiracles very broad. The spaces between 

 these stripes rather broad. Spiracles black. At the posterior extremity 

 of the body is a short, fork-like process. Underside of body pinkish, 

 without markings. Length, about 2 m.m. Food-plant — Grass ( Poa 

 pratensis). I very much regret not to have been able to raise the larvas 

 to maturity, but hope that Mr. James Fletcher, from whom I received the 

 eggs, may have further notes upon this interesting species, 



Ancyloxyplia numitor, Fabr. 



Egg. — Semi-spherical, yellow, rounded at the side and top, base 

 flattened. After two days the egg became dirty-whitish, speckled with 

 bright red. Length, about 1.5 m.m. Width, about .75 m.m. Laid on 

 Grass (Setaria op.), Sept. 8. 



Arzatna Obliquata, G. & R. 



Mature Larva. — Head, subcaudate ; rugose, chestnut brown, some- 

 times jet black; shining. Cervical shield, rugose, chestnut brown, some- 

 times black. Body above, shining olive brown, with numerous very fine trans- 

 verse wrinkles, which are hardly visible to the naked eye ; posterior segment 

 much depressed. Spiracles black. Body beneath, dirty brownish white, 

 including the abdominal legs, which have a chestnut brown or jet black 

 patch on the outer side of each, and the extremities black. Thoracic 

 feet chestnut brown or jet black. Length, about 55 m.m. Found several 

 full grown specimens under decaying stumps, Sept., 188S.
