450 CASEY 



or beaded at the sides ; scutellum obsolete ; elytra even, inflated, 

 very widely embracing the body beneath, the inflexed part sepa- 

 rated from the dorsum by a line strongly convex in section, the 

 epipleurae short, terminating anteriorly at the base of the abdo- 

 men ; prosternum flat, truncate behind, abutting evenly against 

 the equally flat and elevated mesosternum ; legs long, slender, 

 the hind tarsi short but slender, sparsely spinose and not at all 

 grooved beneath, with long flying hairs above as on the femora 

 and tibi^ externally, the basal joint not quite as long as the 

 fourth, the claws evenly arcuate and slender; inet-episterna wide 

 anteriorly, narrow posteriorly, with the suture very feeble ; hind 

 coxai transverse, separated by less than their own width. [Type 

 E. ventricosus Lee] Edrotes 



Body less stout, oblong-oval, subparallel ; head nearly as in Edrotes^ 

 except that the epistoma is declivous and angularly produced at 

 the middle, confounded with the front and limited posteriorly by 

 a broad shallow transverse depression, which becomes deeper 

 .aterally, the lateral lobes thickened but not prominent, broadly 

 rounded, the antennae with the eleventh joint small, the eyes 

 bounded above by distinct carinas ; prothorax with acute and 

 prominent apical angles, closely fitted to the elytra as in Edrotes; 

 scutellum wanting; elytra oblong, carinulate and granulose, the 

 epipleurae only extending anteriorly as far as the apex of the 

 second ventral segment, the hind coxa widely separated, the pro- 

 and mesosterna as in Edrotes; met-episterna very broad; legs 

 short and stout, the tarsi clothed with short spiny hairs, not sul- 

 cate beneath ; body apterous as in Edrotes^ sparsely clothed with 

 coarse decumbent hairs, the sides of the elytra with long erect 

 hairs. [Type P. gratmlata Champ.] * Pimeliopsis 



Edrotes is represented by numerous species scattered through 

 our entire Sonoran fauna, but Pimeliopsis Champ., is now 

 known only by the type species, about 8.0 mm. in length, of 

 which two specimens were taken by H. H. Smith at Venta de 

 Zopilote, in Guerrero, Mexico, and, being unknown to me in 

 nature, will not be further alluded to. 



Edrotes Lee. 

 In this genus the pubescence, usually long and bristling, is 

 frequently lineate on the elytra, owing to the condensation of 

 punctures along a few longitudinal lines, which represent the 

 low carinas of Pimeliopsis , Adesmia and Cranioius. The sur- 

 face is probably always polished but is frequently dull, because 

 of a thin gray-black indument which forms upon it. The 

 species are difficult to classify and describe in a recognizable
