174 CURCULIONID^. 



[LeConte. 



Kansas; one specimen. A very small species, related to 8. tycldoides, 

 and easily known by the narrow scales and rounded sides of the prothorax. 

 The scales are partly abraded, but appear to be mottled in color. 



Group III. Engnomi. 



Following the example of Lacordaire, I recognize as a distinct group a 

 small number of genera which are closely related to the Erirhini proper, 

 and like them have the antennal grooves directed against the eyes ; they 

 differ in having the eyes larger and more prominent, and separated from 

 the margin of the prothorax by the head being more or less prolonged be- 

 hind. The head thus recalls the form already seen in Rhinomacer and 

 Rhynchites, though otherwise there is no resemblance. 



The two species in my collection resemble in appearance small Dorytomus 

 but the thighs are unarmed, and the second joint of the funicle of the 

 antennte is short. 



I will for the present refer them to the genus Phyllotrox, though they 

 differ from the description given by Lacordaire (Gen. Col. vi, 505), by the 

 fii"st ventral suture being well-marked. 



PHYLLOTROX Sch. 



1. P. nubifer, n. sp. 



Elongate, fuscous, thinly clothed with golden pubescence ; antennae, legs 

 and elytra fulvous, the latter with the suture and scutellar region more or 

 less blackish. Length 1.8-2.3 mm. ; .075-09 inch. 



San Francisco, California ; collected by myself. 



Beak rather stout, nearly as long as the prothorax, punctured, feebly 

 channeled from between the antennae for a short distance; eyes rather large, 

 prominent ; anteunne yellow, with the scape reaching to the eyes. First 

 joint of funicle stout, and moderately long, followed by six short joints, 

 club oval, pubescent. Prothorax not lobed behind the eyes, longer than 

 wide, narrowed in front, feebly rounded on the sides, slightly constricted 

 near the tip, rather densely punctured, thinly clothed with shining yellow 

 hair. Elytra wider than the prothorax, elongate, humeri rounded, strise 

 with close-set punctures, interspaces densely punctulate, and sparsely 

 pubescent, brownish-yellow, with the scutellar region and frequently the 

 suture dai'k. Body beneath dark, strongly punctured ; abdomen and legs 

 brownish-yellow. Thighs not toothed, rather thick ; tibiae stout, truncate 

 and not armed at tip, tarsi rather broad, third joint wider, deeply bilobed; 

 claws simple, divergent. 



This insect strongly resembles the figure of Braclwnyx indigena Herbst, 

 as given by Duval, Gen. Col. Eur. iv, pi. 19. 



I have seen a variety from Colorado in the collection of Mr. Ulke, in 

 which the color is bright yellow, only the head, trunk beneath, and the 

 suture near the base of the elytra are dark. 



2. P. ferrugineus, n. sp. 



Smaller than the preceding, entirely ferruginous, sparsely pubescent.
