rf". Elongate, narrow, cylindrictal, very shining; testaceous, the head^ 

 antennae, base and apex of elytra, nietasteruum, abdomen in part, and legs 

 (the bases of the femora, and in one specimen the knees also) black or piceoiis, 

 the pro thorax rufo-testaceous ; the elytral interstices set with long, fine, erect 

 hairs throughoivt, the head also with projecting hairs. Head short, transverse, 

 polished, foveate in the middle between the eyes, the piligerous punctures deep, 

 the ej^es rather small, distant, not reaching the base; antennae long, feebly 

 serrate, joint 11 curved, rather longer than 8-10 united. Prolhorax convex, 

 about as wide as the head, as long as broad, subcordate, deeply constricted 

 before the base, canaliculate anteriorly and with a deep, oblique excavation on 

 each side of the disc behind the middle, the basal margin moderately raised, 

 the surface sparsely, obsoletely punctate. Elytra long, cylindrical, about one- 

 half wider than the prothorax, rounded at the apex ; closely, rather coarsely 

 crenato-striate, the interstices iiiirrow, more or less convex, strongly so at the 

 tip, the piligerous punctures minute; and with a small, oblique, opaque patch 

 towards the sides, not interrupting the striae. Legs slender, t^imple, the femora 

 feebl}' clavate.

Two specimens, varying slightly in the colour of the legs. vSmaller 

 and more slender than the Pei'uvian C. sijinicamln ; the head less exca- 

 vate between the eyes, the latter not so large ; the el^'tra black at the 

 base and apex, with a faint opaque spot near the oviter margin, and 

 the tip unarnted. The structure of the mandibles cannot be ascertained 

 without dissection.

The diagnosis of Disema was apparently, and tiiat of Barsenis 

 certainly, drawn u]) from mal(?s only, thougli the autliors seem to have 

 been unaware of the fact. The females of all of them are rare, and, as 

 they want most of the essential characters used to define these genera, one 

 or two of them have been described as separate species, or placed under 

 Slafira., etc. The numerous S. American forms represented in the col- 

 lections before me divide up into several groups, mainly on S -structures. 

 The chief characters of the genus are — the strongly serrate {Disema 

 s. str.) or llabellate {Barsenis) d -antennae, tliese organs being feebly 

 serrate in the 2 ; and the presence of a depressed opaque area on the.
