98 OTIORHYNCHIDJE. 



[Horn. 



stances are numerous in every tribe of genera which have characters of 

 other tribes, of more or less distant position, in addition to the distinctive 

 characters of the tribe to which they belong. In addition to the above 

 generic characters the outer elytral striae have the characteristic form of 

 the other members of the tribe, the outer stria joins the next inner one third 

 from the base. This is not known in our Otiorhynchini. 



A. griseus, n. sp. 



Form oblong oval, gradually narrower anteriorly, surface densely cov- 

 ered with greyish scales, irregularly variegated on the elytra with darker 

 spots. Head and rostrum as long as the thorax ; a fine medium line extending 

 to the vertex, surface moderately densely scaly. Thorax cylindrical, some- 

 what narrower in front, slightly longer than wide ; apex truncate, base 

 feebly arcuate, sides moderately arcuate, disc convex, moderately densely, 

 but not coarsely, punctured. Elytra oval, one and a half times longer than 

 wide, conjointly emarginate, humeri oblique, feebly prominent, sides 

 moderately arcuate and gradually divergent, apex feebly prolonged ; disc 

 moderately convex, feebly striate, striae with moderate, not closely placed 

 punctures, intervals feebly convex, surface densely scaly, each interval 

 with a single row of minute setae. Body beneath and legs densely scaly, 

 and sparsely setose. Anterior tibiae with distant denticulations within ; at 

 tip (also the middle tibiae) finely mucronate. Length .20-. 24 inch ; 5-6 mm. 



In many of the specimens the intervals slightly alternate in the degree of 

 their convexity. 



Occurs in Texas. 



Group III. Aplirasti. 



Head broader behind the eyes ; scrobes slightly visible from above, deep, 

 directed toward the eyes but not reaching them, gradually broader behind. 

 Antennae moderate. Elytra slightly wider at base than the thorax, humeri 

 obtuse. Scutellum distinct. Articular surface of hind tibiae not cavernous, 

 slightly scaly. Claws connate. 



The structure of the tarsal claws will serve to distinguish this group 

 from either of the preceding. The outer stria of the elytra joins the next 

 inner at one-third from the base as in all the Cyphini and the genge are 

 deeply emarginate. 



One genus constitutes this group in our fauna.

Aphrastus Schonh. Curcul. vii, 1, p. 39. 



Head broader behind the eyes, vertex convex. Rostrum slightly longer 

 and narrower than the head, moderately robust, subangulate, above flat 

 w r ith a fine groove attaining the vertex, tip and gense deeply emarginate. 

 Eyes round, moderately convex. Scrobes short, deep, passing directly 

 backward but not reaching the eyes, moderately dilated behind and slightly 

 visible from above. Antenna? moderate ; scape slightly arcuate, attaining 

 the thoracic margin ; funicle 7-jointed, 1-2 longer, 3-7 short, gradually de- 

 creasing and becoming wider ; club oval. Thorax cylindrical, slightly nar- 

 rower in front, apex and base truncate. Scutellum moderate. Elytra ob-
