feet, cleft near the middle, the inner tooth short, and not turned 

 inward. 



Length, Y-7.75 mm ; width, 1.Y5-2 mm. 



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



Type and paratypes.—V.S.'NM. No. 59563. 



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



Bemarks. — Described from 10 examples (one type) collected at 

 the type locality at an altitude of 3,960 feet, during July 1932 by 

 H. E. Hinton. 



This species is allied to carinifer Waterhouse, but it differs from 

 that species in having the pronotum convex at the middle, the elytra 

 uniformly reddish cupreous, with the tips broadly rounded and not 

 dilated. 



AGRILUS INFroELIS, new species 



Male. — Small, slender, moderately flattened above, strongly shin- 

 ing; head dark green, with a slight aeneous tinge, opaque; pronotum 

 and elytra reddish cupreous, each elytron ornamented with a vague, 

 whitish pubescent spot at apical third; beneath brownish cupreous, 

 with a more or less distinct aeneous or virideous tinge. 



Head with the front wide, nearly fiat, equal in width at top and 

 bottom, lateral margins parallel posteriorly, broadly, arcuately con- 

 stricted on lower half, and without distinct depressions; surface 

 densely, finely granulose, feebly, irregularly rugose, finely, sparsely 

 punctate, clothed with a few short, recumbent, white hairs ; epistoma 

 transverse between the antennae, not elevated, but broadly, deeply, 

 arcuately emarginate in front; antenna short, serrate from the fifth 

 joint, the outer joints slightly transverse and compact; eyes large, 

 oblong, slightly more acutely rounded beneath than above. 



Pronotum about one third wider than long, slightly narrower 

 at base than at apex, widest near apical angles ; sides obliquely nar- 

 rowed from near apical angles to posterior angles, which are rec- 

 tangular ; when viewed from the side the marginal and submarginal 

 carinae rather strongly sinuate, widely separated anteriorly but joined 

 near the base; anterior margin strongly sinuate, the median lobe 

 rather strongly produced and broadly rounded ; base strongly, arcu- 

 ately emarginate at middle of each elytron, with the median lobe 

 strongly produced and broadly subtruncate in front of the scutellum ; 

 disk moderately convex, broadly depressed on each side posteriorly, 

 without distinct median depressions, but with sharply defined, 

 straight prehumeral carinae which extend forward to middle of 

 pronotum; surface feebly granulose, densely but not deeply, trans- 

 versely rugose, finely, sparsely punctate between the rugae, nearly 

 glabrous. Scutellum not transversely carinate, but the surface 

 densely, finely reticulate.
