The following is a translation of Chevrolat's original description : 



Form of Arrilus gemmata Say, linear, granulose and dark vio- 

 laceous; head densely punctate, vertex truncate, moderately convex 

 and bronzy-green ; frontal sulcus transversely impressed posteriorly, 

 antennae attaining the base of thorax, slender and black, joints 5 

 to 10 angulated (5 to 8 triangular) ; thorax just as wide as long, in 

 front straight, disk arcuate, base exteriorly strongly sinuate, at 

 sides arcuately dilated, with the margins deplanate, above deeply 

 f ossulate, disk longitudinally convex and densely transversely granu- 

 lose ; scutellum transversely reflexed ; elytra granulose, parallel, sepa- 

 rately rounded, apex denticulate, base impressed, at humeri reflexed ;

 Cuba, from central part of the island. Collections of Gundlach and 

 Poey. 



This small species rather approaches by its form to our slender 

 species from Europe. 



Gundlach (1891) records collecting in the Cienago de Zapata, Cuba. 

 The species is not represented in the Poey collection in Philadelphia, 

 but there is a single example labeled No. 959 in the Gundlach Museum 

 in Habana, which has not been available for study.

Head feebly convex, with a feeble longitudinal groove; epistoma

 Antennae short, glabrous, and dentate from the fourth joint; first 

 and second joints thick, the first slightly longer than second; third 

 small; the following joints triangular, (except sometimes the apical 

 joint), dentate on the inner side, and armed with a terminal porif- 

 erous fovea. Eyes moderately large, oval, feebly projecting, and 

 parallel on the inner margin. Pronotum wider than long, strongly 

 convex; anterior margin arcuately emarginate; sides arcuately 

 rounded; base transversely truncate. Scutellum very small and sub- 

 triangular. Elytra very convex, truncate, and transversely im- 

 pressed at base ; sides parallel in front ^nd broadly rounded behind.
