nearly as in fulvisetis but becoming still more concave and reflexed 

 at the sides, the thin edge not serrulate, the small hairs less distinct; 

 elytra fully one-half longer than wide, only moderately narrowed 

 basally and widest somewhat before the middle; costae very strong, 

 the first and second only imperfectly confluent midway down the 

 declivity, the intervals smooth but strongly undulato-rugose, the 

 minute granules very sparse and inconspicuous, each with a minute, 

 rather dark hair; abdomen with close asperate punctures and imbri- 

 cato-rugose sculpture, sparser and less pronounced laterally, the 

 fine hairs blackish and inconspicuous; last joint of the left palpus 

 of the male type intact, large and strongly scalene, the right with 

 a large apical excavation on the upper side near the apex. Length 

 (c?) 17-5 mm.; width 8.3 mm. New Mexico, Gissler.

9 Elytral humeri obtusely angulate and distinct, the elytra only 

 moderately narrowed basally. Piceous-black, slightly shining; 

 prothorax twice as wide as long, narrowed anteriorly and posteriorly, 

 the sides strongly rounded, depressed and transversely rugose, the 

 disk sparsely punctate, broadly bisinuate at base, the posterior 

 angles subacute; elytra oval, convex, strongly declivous behind, the 

 suture, two dorsal costse on each confluent before the apex and the 

 lateral margin obtusely elevated, the intervals unequal, not at all 

 punctate; beneath sparsely punctate; epipleura unequal, impunc- 

 tate. Length 18.7 mm. Texas (Llano Estacado). [Pelecyphorus

A Piceous-black, shining; prothorax more than twice as wide as long, 

 narrowed anteriorly, the sides rounded, depressed and trans- 

 versely rugose, the disk rather densely punctate, the base broadly 

 and slightly bisinuate, the hind angles subacute; elytra ovate, 

 convex, strongly declivous behind, the suture, two discal costae 

 on each confluent before the apex and the lateral margin elevated; 

 intervals very unequal, impunctate; beneath punctate. Length 

 20. 2 mm. Texas (Llano Estacado). [Pelecyphorns irrcgitlaris

B Oblong, rather stout, moderately convex, black, slightly shining, 

 the anterior parts duller and obscurely rufescent; head moderately 

 punctate; prothorax very short and broad, fully four-fifths as wide 

 as the elytra, very nearly twice as wide as long, the sides rather 

 strongly and almost evenly rounded, the base broadly bisinuate, 

 with the angles much produced posteriorly and very acute; 

 surface coarsely, confluently punctate, narrowly concave, moder- 

 ately reflexed and transversely rugose at the sides; elytra only 

 about a third longer than wide, widest at the middle, very moder- 

 ately narrowed basally, the sides rounded; surface with the costae 

 distinct, the discal confluent midway down the posterior declivity 

 and thence feebly continued nearly to the apex, where the feeble 

 ridge meets the marginal ridge; interspaces strongly, very con- 

 fusedly, subtransversely rugose and without evident granules
