Apathus, New n. 



The following remarks on this genus are from Mr. Cresson's " List of the North 

 American species of Bombus and Apathus" Proc. Ent. Soc'y Phil., 1863: 



This genus is parasitic on that of Bombus, and resembles it very much iu general 

 appearance. The characters with which to distinguish it from Bombus are as follows : — 

 The posterior tibiae are destitute of corbiculae (or baskets) and are couvex exteriorly ; the 

 basal joint of the posterior tarsi has no tooth at its base above. Iu the female the apex 

 of the abdomen curves under, and the apical segment beneath has the lateral margins 

 elevated. The mandibles have a single notch, while those of Bombus are distinctly 

 toothed. This genus has no workers. 



The males may be distinguished from those of Bombus by the posterior tibiae being 

 exteriorly convex and thickly coated with short hairs. The males of the latter genus 

 have the exterior surface of the posterior tibiae concave in the centre, with a few scattered 

 hairs, and are fringed at the exterior margins. 



The economy of our species is almost unknown.

INSECT DESTRUCTIVE TO PINE TREES. — NEPHOPTERYX ZIMMERMANI. 



BY D. S. KELLICOTT, BUFFALO, N. Y. 



This pine-boring Pyralid was described by Prof. A. R. Grote in a paper read at the 

 Nashville Meeting, 1877, of the American Assoc. for the Adv. of Science, and published 

 in Canadian Entomolot/ist, vol. ix., 161. During the summer and autumn of 1878, and 

 again this year, I have made some observations upcn the occurrence, larval habits and 

 parasitic enemies of this moth, and am able to state concerning them some additional 

 facts of interest. 



The moth, it appears, is pretty widely spread, aud it seems rather odd that it should 

 not have been discovered until 1877, having been overlooked by our excellent economic 

 Entomologists. I have met with it in some one of its stages in the following localities : 

 It occurs not uncommonly in both foreign and native pines in and about Buffalo ; many 

 of the trees of this species in the Niagara St. Parks have been bored by it. I found it 

 quite abundant in small white pines of the forest at Chehtowaga, Erie Co., N. Y. At
