THE STATE ENTOMOLOGIST. 75 



There is but one other described, N. A. Amphipyra, namely, the A, iiwrnala of Grote— (Pro 

 Enl. Soc, Phil., Ill, p. 86,) which upon the very face of it, seems to be but a small variety of 

 pyramidoides, as will be seen by comparing his description with that found above. The species 

 was described from a single specimen belonging to Mr. Win. Saunders, of London, Ont., who 

 agrees with me in believing it to be but a variety of pyramidoides. 



I have a unique in my cabinet which differs so .emarkably in the front wings from pyramidoides 

 that I feel constrained to briefly describe it, and yet in all other characters it so closely resem- 

 bles that species that I should hesitate to do so, had I not bred it from the larva. It looks exactly 

 as though something had been sprinkled uniformily over the front wings and had eaten the dark 

 color away in spots and splashes, but the specimen is in reality perfect, with not a scale rulHed* 

 It may be called the Spattered Copper Underwing r — 



Amphipyra conspersa, N. Sp. — Larva. — Found full grown July 2nd, 1867 on Hazel. No pyra- 

 mindal hump, and of a uniform emerald-green, the dorsal palpitations visible and the stigmata pale 

 with a black annulation, but with no other markings either on the head, body or legs. 



Imago— Like pyramidoides in every particular except that the brown of front wings is almost 

 uniformily spattered over, more or less suffusely with pale grayish spots so that no regular marks 

 appear. The costal marks are however tolerably distinct as in pyramidoides and by careful exami- 

 nation and comparison, traces of the more conspicuous marks of that species may be discerned. 



Described from one § bred July 31st. 



THE GRARE-ROOT BOKER-^fferia polistiformis, Harr. 



(Lepidoptera, iEgei idse.) 



The most common root-borers of the Grape-vine in this State are 

 those which I have termed Gigantic Hoot- borers, namely, the larvae 

 of two large beetles (Prionus I atioollis and P. imhricornls) which 

 were treated of in my previous Reports. The insect now under con- 

 sideration is a moth and not a beetle and has for a number of years 

 been known as THE Grape-root Borer. It bears a very close resem- 



[Fig. 33.] 



blance to the common Peach Borer, both in habit, and in the size and 

 general appearance of the larva, but it is a somewhat larger insect 

 and the moths differ mater ally. 



It has usually been c nsidered a Southern insect and certain it is 

 that it is not as destructive in the vineyards of Missouri as the Gigantic 

 borers. But I captured specimens of the moth and found the larva 

 in St. Louis county last summer, and it has long been known to be 

 destructive throughout Kentucky. It was also reported around Cin-
