strongly inflated toward base in the female than in the male, 

 nearly as in Centrinus hospes, which inhabits the same region. 

 My series consists of seven specimens. 



THYSAtfOCNEMIS Lee. 



In this genus the sexual divergencies in the structure of the beak 

 are extremely pronounced and far more noticeable than in Tylop- 

 terus, with which it is closely allied ; the present forms may be 

 distinguished from Tylopterus, however, by the much coarser, less 

 dense and non-sericeous vestiture. The fringe of hairs of the front 

 tibiae in the male is not a character of generic importance, and often 

 disappears completely. The five species in my cabinet may be 

 mutually distinguished by the following table : — 



Elytral intervals subequal in width and prominence. 



Body pale rufo-testaceous, the elytra with a broad, darker and generally 

 less densely squamulose band, narrowed toward the suture, often indis- 

 tinct ; sometimes also with a short angulate sutural band of paler scales 



near apical third fraxini Lee. 



Body piceous-black, the beak and legs rufous, the tibia? with a narrow sub- 

 median band blackish, the femora dark except toward base; vestiture 

 strongly mottled with black and whitish, fulvous near the base of the 

 elytra especially near the humeri, and on the pronotum except toward 

 the sides and in the middle toward base ; on the elytra a whitish band at 

 basal fourth and a narrower angulate band at apical third are especially 

 noticeable. Head squamose ; eyes separated by barely one-half of their 

 own width ; beak in the male short but rather thin, feebly arcuate, as 

 long as the prothorax, with the antennae inserted at apical third ; in the 

 female very thin, smooth, cylindrical; evenly, distinctly arcuate, as long 

 as the head and prothorax, with the antennae inserted at about the middle ; 

 antennae long, the funicle slender, with the basal joint more than one-half 

 as long as the remainder, club robust, blackish, not as long as the pre- 

 ceding six joints. Prothorax one-half wider than long, narrowed in apical 

 third, the sides thence parallel and almost straight to the base. Elytra 

 nearly one-half wider than the prothorax, three times as long, parallel, 

 broadly rounded at apex, with the subapical umbones rather distinct. 

 Length 3.0-3.3 mm.; width 1.3-1.6 mm. Arizona (Winslow). Mr. H. 



F. Wickham grapliica n. sp. 



Body uniformly pale ochreous-testaceous throughout. 



Vestiture dense, pale yellowish, consisting of elongate subrecumbent 

 scales, intermixed with narrower hairs on the pronotum, each elytral 

 interval with a single series of very broad semi-erect distant scales. 

 Head convex ; eyes separated by rather more than one-half of their 

 own width ; beak in the male rather thick, cylindrical, feebly arcuate, 

 finely, sublinearly punctate, barely as long as the head and prothorax ;
