ERIRHININI. 189 



1. P. setosus, n. sp. 



Black, covered with a dirt-colored crust ; prothorax deeply and broadly 

 channeled ; elytra finely striate with the alternate interspaces elevated, and 

 bearing each a row of long bristles ; a transverse common pale spot is seen 

 behind the middle, extending from the suture to the third stria. The an- 

 tenna and legs are brown. Length 2.4-2.8 mm.; .09-.12 inch. 



Texas, Belfrage; two specimens. 



Group VIII. Phycocoetes. 



This group is established upon one small species of pale brown color, 

 which lives under sea-weed cast up by the waves at San Diego, California. 

 It differs greatly from all the other members of the tribe, by the front 

 coxae which are not absolutely contiguous, but separated by a very narrow 

 lamina of prosternum, and by the very short metasternum, only one-third 

 the length of the first ventral segment. 



In color, form and sculpture it resembles EmpJiyastes, but differs from 

 that genus by such strong structural characters, that I cannot venture to 

 place them together in one tribe. 



Body clothed with very sparse pubescence. Beak cylindrical, slightly 

 curved, as long as the prothorax, not very slender; mandibles of normal 

 form; antennal grooves commencing near the tip, extending to the eyes, 

 which are small, rounded, and coarsely granulated; front continuous with 

 the beak. Antennae with scape extending to the eyes, funicle .7 -jointed, 

 first joint stouter and longer, second nearly as long as the first, 3-6 rounded, 

 seventh transverse, rounded; club rather small, oval, annulated, pubescent. 

 Prothorax oval, longer than wide, rounded on the sides, not constricted 

 nor lobed in front. Elytra oval, a little wider than the prothorax, humeri 

 rounded, not prominent, base feebly emarginate. Prosternum rather long 

 in front of the coxae, flattened, not sulcate; joining the posterior point, so as 

 to slightly separate the front coxae which are large and globose. Mesoster- 

 num declivous, rather widely separating the middle coxae; side pieces with 

 the episterna very large, and the epimera very small, extending along the 

 margin of the elytra. Metasternum very short, side pieces very narrow, but 

 distinct; hind coxae oval, very widely separated, extending to the margin 

 of the elytra. Ventral segments, first longer than the second, separated 

 by a sinuous suture; third and fourth united equal to second; fifth 

 shorter than second, rounded at tip. Legs moderate, thighs clavate; tibiae 

 slender, nearly straight, slightly mucronate at tip, hind pair truncate, but 

 without corbels; tarsi rather short, spongy beneath; third joint broader, 

 deeply bilobed; fourth as long as the two preceding with rather large 

 diverging simple claws. 



The generic and group characters are combined in the above description.
