Head nearly flat; surface coarsely, deeply, uniformly, confluently 

 punctate; epistoma wide and slightly depressed between antennal 

 cavities, broadly, feebly, arcuately emarginate in front. 



Pronotum strongly convex, strongly deflexed at sides, nearly one- 

 third wider than long, slightly wider at base than at apex ; sides nearly 

 parallel from bases to apical sixths, then arcuately narrowed to apical 

 angles; lateral margins when viewed from side sharply defined and 

 sinuate ; disk with three deep, oblong, basal depressions extending to 

 middle of pronotum, the median one with a narrow, longitudinal 

 groove at middle ; surface coarsely, deeply, densely, uniformly punc- 

 tate. Scutellum twice as wide as long, feebly rounded at sides, and 

 surface smooth. 



Elytra as wide as pronotum at base ; sides strongly, angularly ex- 

 panded behind humeral angles, broadly, feebly arcuately constricted 

 at middles, then strongly, obliquely converging to tips, which are 

 acute ; lateral margins coarsely serrate posteriorly ; basal depressions 

 shallow, broadly transverse; surface slightly transversely rugose bas- 

 ally, irregularly striato-punctate, the striae slightly impressed toward 

 apices; intervals finely, densely granulose, with a few coarse, incon- 

 spicuous punctures intermixed. 



Abdomen beneath coarseh-, sparsely punctate, intervals finely, in- 

 conspicuously reticulate, sparsely clothed with short, recumbent, whit- 

 ish hairs ; last visible sternite deeply, narrowly, arcuately emarginate. 



Length 11 mm., width 3.5 mm. 



Tyfe locality. — Indiera Alta Maricao, Puerto Rico. 



Type.— U. S. N. M., No. 58798. 



Described from a single specimen collected June 5, 1944, by J. A. 

 Ramos. 



This species is closely allied to Peronaemis thoracicus Waterhouse, 

 but it diilers from that species in having the sides of the pronotum 

 parallel posteriorly and not expanded at the bases, and the basal de- 

 pressions shallower, the elytra uniformly olivaceous green without 

 any distinct brownish or cupreous spots, and the underside of the ab- 

 domen uniformly brownish green. 



Genus TAPHROCERUS Solier 



TAPHROCERUS HAITIENSIS, new species 



Broadly elongate, strongly attenuate posteriorly, moderately con- 

 vex above, moderately shining, black, with a vague greenish or bronzy 

 tinge in different lights. 



Head subequal in width to pronotum at base, and when viewed from 

 above truncate in front, without a distinct longitudinal groove; front 

 wide, with a broad, shallow depression between the eyes, and with the 

 sides nearly parallel ; surface coarsely granulose, coarsely, shallowly.
