recumbent, -wliite hairs; prosternal lobe broad, strongly declivous, 

 and broadh^, rather deeply, arcuately emarginate in front; proster- 

 nal ]3rocess broad, the sides parallel to behind the coxal cavities, 

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

 nearly straight, unarmed at apices. Posterior tarsi about one half 

 as long as 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 the outer one, and not 

 turned inward. 



Length, 5.25-7 mm; width, 1.3-1.75 mm. 



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



r^/^e.— U.S.N.M. No. 49556. 



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



Remarks. — Described from three females (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 megerlei Fisher, but it differs from that 

 species in having the head, pronotum, and scutellum reddish- 

 cupreous or aureous, and the elytra black, with a feeble purplish 

 tinge. The species varies considerably in size, and in the paratypes 

 the sides of the pronotum are more obliquely narrowed posteriorly 

 than in the type. The anterior and posterior tarsal claws are missing 

 on the type. 



AGRILUS RESPLENDENS, new species 



Female. — ^Moderately elongate, robust, feebly narrowed posteriorly, 

 strongly flattened above, rather strongly shining, uniformly greenish 

 blue above and beneath. 



Head with the front wide, rather strongly convex, distinctly wider 

 at top than at bottom, lateral margins obliquely converging from 

 top to botttom, and rather deeply, broadly concave, the concavity 

 extending from occiput to epistoma ; surface feebly, coarsely rugose, 

 coarsely, densely punctate, sparsely clothed with short, erect, in- 

 conspicuous hairs; epistoma strongly transverse between the anten- 

 nae, moderately elevated, broadly, rather deeply, arcuately emar- 

 ginate in front, the surface deeply, triangularly depressed ; antenna 

 short, serrate from the fourth joint, the outer joints triangular and 

 about as long as wide ; eyes large, equally rounded above and beneath. 



Pronotum nearly one half wider than long, subequal in width at 

 base and apex, and widest near apical third ; sides feebly, arcuately 

 rounded anteriorly, more obliquely narrowed to the posterior angles, 

 which are rectangular; when viewed from the side the marginal 

 carina is arcuate, the submarginal carina strongly sinuate, the two 

 carinae widely separated anteriorly, and connected to each other at 

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