the largest. The stigmata or breathing-pores are broadly oval, and 

 bordered with red. A magnifier shows a short blackish hair upon each 

 of the ordinary piliferous spots. The legs are reddish. 



The Moth. 



The moth is quite unlike the usual slender-bodied and broad-winged 

 Qeometridm, having a short and stout abdomen, in which, together with 

 ils proportionate spread of wings and their general shape, it strongly 

 resembles many of the Bombycicke. Indeed until its structural char- 

 acters are studied, it seems quite out of place in an arranged collection 

 of the Geometridm. 



Fig. 17, taken from Saunders' /wsecAs Injurious to Fruits, gives good 



representation of the insect. The 

 body and the thorax are gray, the 

 latter with a white collar. The 

 wings are gray, dotted, streaked and 

 lined with black. Two black lines 

 bound the central portion of the 



F,«.ir.-Thec,,nantAmpi,Ma«y,.AMPm».sv-s ^ings, the outer one of which is 

 eoGNATARiA Guence. Strongly two-toothed on the primar- 



ies, and one-toothed on the secondaries. Between these lines, the 

 ground is white sprinkled with black, and traversed centrally by a two- 

 lobed shade on the primaries. The antennae are broadly pectinated in 

 the male; the abdomen short and quite stout in the female. Expanse 

 of wings, two inches. 



Life-History. 



There are two annual broods of this insect. From larvae collected in 

 August, I have obtained the imago in the following May. From larva; 

 taken by Miss Morton on the 28th of June, nearly full-grown, and which 

 entered the ground for pupation on the roth and 12th of July, the moths 

 were produced from the 12th to the 2 2d of August. The last of these at- 

 tracted several males during the night following its appearance, and de- 

 posited a large number of eggs on the succeeding night. The larvae from 

 the eggs were fed upon the honey locust, but being only about one- 

 third grown when the leaves fell, they were not matured. They doubt- 

 less died from starvation and exposure in the bag in which they were 

 confined upon a locust, where no suitable shelter could be had, for they 

 were observed traveling about within the bag during all the warmer days 

 of October and November. 



Other larv?e taken by Miss Morton during the summer of 1882, bur- 

 ied themselves in the ground, from the i6th to the 20th of September, 

 but failed to produce the perfect insect.
