10 PEOCEEDINGS OP THE NATIONAL, MUSEUM vol.82 



Abdomen beneath vaguely granulose, rather densely marked with 

 fine, transverse, crenulate lines, which are denser on basal segments, 

 rather densely, finely punctate, and sparsely, uniformly clothed with 

 short, recumbent, white hairs; first segment convex at middle, the 

 suture between the first and second segments not distinct at the 

 sides; last segment broadly rounded at apex; vertical portions of 

 segments not conspicuously pubescent; pygidium densely, coarsely 

 punctate, without a projecting carina at apex. Prosternum feebly 

 rugose, sparsely, coarsely punctate, and sparsely clothed with short, 

 recumbent, white hairs; prosternal lobe broad, strongly declivous, 

 and broadly, rather deeply, arcuately emarginate in front ; prosternal 

 process broad, the sides parallel to behind the coxal cavities, then 

 obliquely narrowed to the apex, which is acute. Tibiae slender, 

 nearly straight, the anterior and middle pairs armed with a small 

 tooth on inner margin at apices. Posterior tarsi distinctly shorter 

 than tibiae, the first joint as long as the following three joints united. 

 Tarsal claws similar on all feet, cleft near the middle, the inner tooth 

 broad, distinctly shorter than outer one, and not turned inward. 



Female. — Similar to the male but the tibiae not armed with a 

 tooth at apices. 



Length, 4.5-7.75 mm; width, 1.2-1.8 mm. 



Type locality. — Tejupilco, Mexico, D.F. 



Type and paratypes. — U.S.N.M. No. 49555. 



Paratypes. — In the H. E. Hinton collection. 



Remao'ks. — Described from eight examples (one male type) col- 

 lected at the type locality at an altitude of 3,960 feet, during July 

 1932 by H. E. Hinton. 



This species is allied to consobrinus Duges, but it differs from 

 that species in being uniformly olivaceous-green above, with the 

 elytra uniformly pubescent, and the pronotum without a median de- 

 pression. The small series of specimens examined show considerable 

 variation in size, and in some of these examples the upper surface 

 has a distinct golden-green tinge. 



AGRILUS SILVICOLA, new species 



Fetnale. — Kather robust, flattened above, strongly shining; head, 

 pronotum, and scutellum reddish cupreous; elj^tra black, with a 

 feeble purplish tinge; beneath aeneous, with a distinct greenish 

 reflection. 



Head with the front rather wide, slightly convex, about equal in 

 width at top and bottom, lateral margins parallel, and with a shal- 

 low, longitudinal depression extending from occiput to epistoma, the 

 depression distinctly broader on the lower half of the front ; surface 

 coarsely, irregularly, but not deeply rugose, coarsely, sparsely punc-
