182 Coleopterological Notices, III. 



in large blotches, especially in a large discal area before the middle and a 

 broad transverse band behind the middle, the suture narrowly pubescent 

 throughout. Abdomen extremely densely pubescent, the last three segments 

 sparsely so along the basal margins, the denuded points obsolete. Legs 

 moderately robust, densely clothed, the femora not distinctly annulate. 

 Length 13.7 mm. ; width 6.0 mm. 



California (near the southern boundary). Mr. Dunn. 



A large and distinct species, represented by a single specimen. 

 It is allied to porosus but is much larger and with larger denuded 

 areas on the elytra, a more conical prothorax, more narrowly 

 pubescent and less sulcate beak, and differs also in several other 

 important respects. The vestiture, where not denuded, is denser 

 than in porosus, and consists of rather broad attenuate scales, re- 

 cumbent and mutually overlapping, while in poi-osus it is composed 

 of very short robust or subsquamiform hairs which are erect, and, 

 although dense, everywhere mutually separated. The posterior 

 femora mfarctus are longer than in porosus, extending nearly to 

 the middle of the fifth ventral segment, while in the latter they ex- 

 tend scarcely beyond the base of the fourth. 



D. saginatus n. sp. — Very robust, convex, the integuments black and 

 rather strongly shining throughout ; the vestiture short, broadly squami- 

 form, very dense and persistent throughout ; pale ochreous-cinereous in color. 

 Head and beak densely clothed throughout and with large widely scattered 

 punctures, which are not concealed by the vestiture ; beak not as long as the 

 prothorax, broadly flattened and without distinct sulcations or carina. Pro- 

 thorax scarcely one-fifth wider than long, the sides feebly convergent from base 

 to apex, strongly tuberculate at apical fourth, the sides thence to the base 

 feebly arcuate ; apex truncate, two-thirds as wide as the base, the latter 

 broadly angulate throughout and without distinct scutellar lobe ; disk very 

 slightly wider at base than at the subapical tubercles ; very broadly, feebly 

 impressed before the scutellum, sparsely, very coarsely foveate, the bottoms of 

 the foveas polished, the interspaces rather strongly, densely punctate ; along 

 the middle there is a very narrow opaque but non-pubescent line, the vesti- 

 ture dense laterally as usual. Elytra one-half longer than wide, two and 

 three-fourths times longer, and, behind the middle, nearly four-fifths wider 

 than the prothorax ; sides nearly straight, obliquely, strongly convergent in 

 apical third, the apex narrowly, arcuately subtruncate ; humeri obliquely 

 truncate ; disk slightly widest behind the middle, with unimpressed rows of 

 very deep, distinct, moderately large punctures, which, in the small oblique 

 subdenuded spot at basal third, and another nearer the suture behind the 

 middle, become very large and conspicuous ; there is also a small denuded 

 spot near the side at basal fourth. Abdomen and legs extremely densely 

 clothed throughout, the small denuded points of the former very sparse. 

 Length 15.5 mm. ; width 6.6 mm.
