ing carina at apex. Prosternum finely, rather densely punctate or 

 rugose, and sparsely clothed with long, erect inconspicuous hairs; 

 prosternal lobe rather broad, vaguely declivous, and very broadly, 

 feebly emarginate in front; prosternal process broad, feebly ex- 

 panded behind the coxal cavities, then obliquely narrowed to the 

 apex, which is obtusely rounded. Tibiae slender, nearly straight, 

 and the anterior and middle pairs armed with a short tooth on inner 

 margin at apex. Posterior tarsi distinctly shorter than tibiae, and 

 the first joint as long as the following two joints united. Tarsal 

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

 and broad, and not turned inward. 



Length, 10.75 mm. ; width, 2.T5 mm. 



Female. — Differs from the male in being broader and more robust, 

 front of head uniformly cupreous, antennae slightly shorter, and the 

 prosternum more coarsely punctured and not clothed with long erect 

 hairs. 



Length, 12.5 mm. ; width, 3.75 mm. 



Type locality. — San Jose, Costa Rica. 



Type and allotype.— Cdii. No. 41604, U.S.N.M. 



Described from two examples, male and female, collected on 

 Erythrina ruhrinervia, at the type locality, July 8, 1923, by Ferd. 

 Nevermann. 



This species is allied to oculatus Waterhouse described from Mex- 

 ico, but oculatus differs from it in having the pronotum transversely 

 depressed along the base, with the sides only feebly rounded, the 

 elytra expanded behind the middle, and the surface fuscous, strongly 

 shining, and ornamented with numerous aeneous spots and markings 

 which are finely rugose. The species resembles in form some of the 

 species of the genus Trypantius. 



AGRILUS RAVENTAZONUS, new species 



FeTmde. — Elongate, slender, subopaque, and strongly flattened 

 above; above brown, with a more or less cupreous tinge, the head 

 slightly more reddish cupreous, and the elytra ornamented with white 

 pubescent designs ; beneath brown, with distinct aeneous and cupreous 

 reflections, and more shining than above. 



Head with the front rather wide, slightly convex, vaguely wider 

 at top than bottom, the lateral margins feebly, arcuately expanded at 

 middle, a moderately deep dej^ression extendinir from occiput to 

 middle of front, the depression deeper and broader on vertex, and 

 with a shallow, elongate, triangular depression behind the epistoma; 

 surface glabrous, more or less longitudinally rugose on occiput and 

 vertex, sparsely, irregularly punctate on lower half, and more densely 

 and finely punctate in the triangular depression; epistoma slightly
