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

 then subtruncate to the median tooth, which is acute. Tibiae 

 slender and unarmed at apices. Posterior tarsi slightly shorter than 

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

 Tarsal claws similar on all feet, cleft near the middle, the teeth 

 slender and acute at tips, about equal in length, and the inner one 

 turned inward. 



Female. — Differs from the male in having the first abdominal seg- 

 ment strongly convex at middle and the presternum without long, 

 erect, white hairs. 



Length, 7.5-9.75 mm ; width, 2-2.5 mm. 



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



Type and paratypes. — U.S.N.M. No. 49562. 



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



Remarks. — Described from nine examples (one male type). The 

 type and seven paratypes were collected at the type locality at an 

 altitude of 3,960 feet, during July 1903, by H. E. Hinton, and one 

 paratype was collected at Eeal de Arriba, Mexico, D.F., at an altitude 

 of 6,300 feet, July 16, 1932, by the same collector. 



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

 that species in having the posterior angles of the pronotum rectangu- 

 lar, the prehumeral carinae connected to the lateral margins, and the 

 pubescent spots on the elytra differently placed. 



AGRILUS VELASCO, new species 



Male. — Rather robust, rather strongly flattened above, and strongly 

 shining; head aeneo-virideous, opaque; pronotum and elytra reddish 

 cupreous; beneath brownish cupreous, with a vague aeneous or 

 virideous tinge. 



Head with the front rather wide, flat, wider at top than at bottom, 

 lateral margins parallel on upper half, distinctly, broadly, arcuately 

 constricted on lower half, and broadly, longitudinally depressed on 

 vertex and occiput ; surface densely, finely granulose, feebly, coarsely, 

 irregularly rugose, coarsely, sparsely punctate, and rather densely 

 clothed with moderately long, semierect, white hairs; epistoma 

 rather wide between the antennae, feebly elevated, and very broadly, 

 deeply, arcuately emarginate in front; antenna moderately long, 

 serrate from the fifth joint, the outer joints triangular, rather com- 

 pact, and about as long as wide; eyes large, strongly oblong, and 

 about equally rounded above and beneath. 



Pronotum slightly wider than long, feebly wider at apex than at 

 base, and widest near middle; sides parallel anteriorly, obliquely 

 narrowed behind the middle to the posterior angles, which are rec- 

 tangular ; when viewed from the side the marginal and submarginal 

 carinae feebly sinuate, narrowly separated anteriorly, and connected
