polished ; pubescence very short, dense, pale cinereous in color. Head 

 coarsely, somewhat closely punctured, the beak much shorter than the pro- 

 thorax, about two-thirds longer than wide, densely pubescent and narrowly, 

 feebly bisulcate above, abruptly nearly glabrous at the sides. Prothorax one- 

 fourth wider than long, widest at the anterior tubercles which are small but 

 very pronounced ; sides thence to the base parallel and straight ; base broadly 

 angulate, the scutellar lobe slightly produced and rounded ; apex subtruncate, 

 but slightly more than two-thirds as wide as the base ; disk very coarsely, 

 deeply foveate, the bottoms of the fovese highly polished, the interspaces 

 densely and rather strongly punctate ; pubescence dense laterally, the inner 

 margin of the pubescent area sinuous. Scutellum very small. Elytra scarcely 

 two-thirds longer than wide, two and one-half times longer, and, in the mid- 

 dle, two-fifths wider than the prothorax ; sides arcuate, obliquely convergent 

 behind to the apex which is rather acutely ogival ; humeri not prominent ; 

 disk with series of extremely large deep and somewhat distant punctures, the 

 alternate intervals distinctly elevated and costiform, the vestiture imperfectly 

 denuded in a large transverse discal area before the middle and a narrower 

 transverse band three-fifths from the base, the sutural interval evenly pubes- 

 cent throughout. Abdomen very densely pubescent but sparsely so on seg- 

 ments three to five except at the sides and along the apices, the small denuded 

 points nearly obsolete. Legs moderately stout, densely clothed, the femora 

 annulate at apical third. Length 11.5 mm. ; width 5.0 mm. 



Lower California (Cape San Lucas). Cab. LeConte. 



The unique type is in an almost perfect state of preservation, 

 and the species may be easily identified by its very coarse punc- 

 tures of the elytral series, feebly bisulcate beak and peculiarities of 

 the vestiture which will be more fully described under the next 

 species. 



I>. farctlis n. sp. — Robust and convex, oval, black and rather shining 

 throughout, the vestiture cinereous. Head coarsely, sparsely punctate, the 

 punctures deep and variolate ; beak three-fourths longer than wide, slightly 

 shorter than the prothorax, densely pubescent above, glabrous at the sides, 

 the pubescent region much narrower than the beak and scarcely perceptibly 

 bisulcate, the lateral edges broadly convex. Prothorax more than one-fourth 

 wider than long, subconical in form, slightly wider at base than at the ante- 

 rior tubercles, the latter small and but moderately prominent, the sides behind 

 them slightly divergent to the base and nearly straight ; base broadly angu- 

 late, the slightly produced scutellar lobe angulate, the apex broadly arcuate, 

 scarcely two-thirds as wide as the base ; disk coarsely, extremely unevenly 

 foveate, a median discal area before the middle more or less impunctate and 

 finely canaliculate ; vestiture obliquely dense laterally. Elytra nearly three- 

 fourths longer than wide, two and one-half times as long as the prothorax ; 

 sides broadly arcuate ; humeri not prominent ; disk broadly rounded in 

 apical third, having series of very large deep somewhat distant punctures, 

 the alternate intervals but feebly elevated, the vestiture in great part denuded
