124 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 65 



a rather long inconspicuous hair; eyes large, strongly convex, more 

 acutely rounded at bottom than at top, and separated on the occiput 

 by about one-half the distance between the antennal cavities; epis- 

 toma deeply and narrowly emarginate in front, the lobe on each side 

 forming an arc from the bottom of the emargination ; aatennae 

 short, cupreous, the third joint about as long as the following two 

 joints united. Pronotum strongly transverse, one and three-fourths 

 times as wide as long, widest at apical third, slightly narrower be- 

 hind than in front ; sides broadly rounded anteriorly, then obliquely 

 attenuate to the posterior angles, which are rather obtuse; anterior 

 margin feebly arcuately emarginate; base rather strongly bisinuate, 

 with the median lobe broadly rounded and feebly truncate in front 

 of scutellum ; surface evenly convex and without impressions, densely 

 and coarsely punctate, the punctures rather deep and well sepa- 

 rated; intervals finely and densely granulose. Scutellum small, tri- 

 angular, the sides equal in length, and the surface obsoletely granu- 

 lose. Elytra distinctly wider than pronotum at base; sides broadly 

 rounded at humeral angles, nearly parallel to behind middle, where 

 they are slightly wider, then arcuately attenuate to the tips, which 

 are separately narrowly rounded ; lateral margins coarsely serrate to 

 middle, the teeth very short and widely separated; humeri promi- 

 nent; base feebly angularly lobed; surface without costae, but each 

 elytron with a deep round impression at basal lobe, a broader but 

 more shallow one at humerus, an obsolete one along margin behind 

 humerus, and a broad obsolete impression on the antemedian green 

 area, coarsely, densely, and irregularly punctate, the punctures some- 

 what confluent toward the apex; intervals densely and coarsely 

 granulose. Abdomen beneath coarsely, deeply, and irregularly punc- 

 tate; intervals obsoletely granulose and more shining than above; 

 first segment not impressed at middle; last segment with the lateral 

 margins entire, with an obsolete serrate submarginal ridge, and the 

 apex feebly truncate. Prosternum with a narrow rounded lobe in 

 front; surface more densely punctured than abdomen; prosternal 

 process flat, triangularly expanded behind the coaxal cavities, and 

 with a very small obtuse tooth at apex; anterior coxal cavities 

 separated from each other by about their OAvn diameter. Femora 

 robust; anterior pair with a large acute tooth on the outer edge, 

 closer to the apex than base, and finely serrate on the exterior mar- 

 gin. Anterior tibiae feebly arcuate near base, somewhat flattened, 

 and with an obsolete dilatation on inner margin near apex; middle 

 and posterior pairs straight and subcylindrical. 



Length, 5.4 mm. ; width, 2.5 mm. 



This species was described by Fabricius (1798) from the Island 

 of St. Thomas, and the above description was made from a specimen 

 from the type locality, kindly loaned by the British Museum. Herbst
