[LeUonte. 



Atlantic slope; found also by Mr. Crotch at San Diego and San Bernar- 

 dino, California. 



A small yellowish -brown insect, densely clothed with yellow pubescence, 

 with a large dark spot near the base and another transverse one behind the 

 middle, connected by a sutural stripe; sometimes there is an appearance of 

 a third spot near the tip of the elytra. 



This insect might be easily confounded with some of the varieties of 

 Phyllotrox nubifer, but the elytra are less broadly rounded at tip, and the 

 claws are not simple, but broadly appendiculate. It varies greatly in size, 

 1.8-2.9 mm.; .07-.11 inch. Bred by Mr. Walsh from a Cecidomyidous 

 gall; 8. brassicoides of Salix longifolia. 



Tribe X. PBIONOMERI3JI. 



This tribe contains a few small species of robust form, easily known by 

 the following assemblage of characters : 



Beak stout, sometimes short and flat: antennae inserted about the middle, 

 scape extending upon the eyes which are large and rounded ; funicle 

 7-jointed, club very large, pubescent, oval pointed, almost articulated. 

 Prothorax without postocular lobes, front coxae contiguous; prosternum 

 short, not emarginate. 



Ventral sutures deeply impressed; the first is straight, the others strongly 

 angulated at the sides; fifth segment scarcely longer than the fourth. Legs 

 stout, tibiae with a slender terminal hook ; tarsi dilated, spongy beneath ; 

 third joint bilobed, claws appendiculate. Pygidium more or less visible. 

 Beak as long as prothorax. sub-cylindrical; long; front 



thighs with a large serrated tooth Prionomerus. 



Beak short, broad and flat; thighs with a small acute 



tooth Piazorhinus.

Atlantic States. I do not know why Gyllenhal has suppressed the spe- 

 cific name proposed by Say, in favor of one taken from Dej can's Cata- 

 logue. It is unfortunate that the generic name given by Say was not ac- 

 companied with a proper description, as it would then (1831) have had 

 precedence over the homonyms of Silbermann in Coleoptera, and Laporte 

 in Hemiptera.

Atlantic States. The antennae are scarcely geniculate, and being in- 

 serted nearer the eyes in consequence of the shortness of the beak, the 

 scape is less elongated than in the preceding genus. I observe in my spe- 

 cimens that the thighs are armed with a small but acute tooth about the
