thick, the first funicular joint stout, nearly as long as the next 

 three, the outer joints gradually a little wider and compact, the 

 club short, obtuse, broadly oval, rather abrupt and but little longer 

 than the preceding three joints as a rule. The prosternum is 

 broadly concave, squamose, and separates the tarsi by about a 

 third their width. The legs, on the whole, are of the usual structure, 

 but are here opaque and with the femora much longer than the 

 tibiae and having a few close-set denticles medially beneath, the 

 tarsi normal, but with small and very slender, almost contiguous 

 claws. The prothorax is feebly tubulate at apex and with the 

 basal lobe small, gradual and broadly rounded, the scutellum sub- 

 quadrate, tumid, rough and more or less squamulose, the elytra 

 with strongly punctured striae and finely carinulate intervals. The 

 dense opacity of the integuments is caused by an almost undefinable 

 minute subreticulate sculpture, the minute discrete ground punc- 

 tures of Torcus not evident. The three species now at hand are the 

 following: 



Elytra strongly narrowed and with oblique and broadly arcuate sides from the 

 humeri to apex, their surface strongly alutaceous. Body more oval, strongly 

 convex, dark red-brown, the elytra somewhat clearer, glabrous above, having 

 fine slender sparse and scarcely visible pale squamules throughout beneath; 

 beak (o") densely punctate and opaque, feebly arcuate, not very slender 

 and as long as the prothorax, the latter but slightly wider than long, the 

 feebly converging sides slightly and subevenly arcuate to the shallow apical 

 constriction, the truncate apex half as wide as the base; punctures strong, 

 deep, extremely dense and longitudinally subconfluent, with a very fine but 

 sharply marked, even and subtumid smooth median line, not attaining the 

 apex; elytra two-thirds longer than wide, a fourth wider than the prothorax 

 and between two and three times as long; apex narrow, the humeri rather 

 broadly subtumid; striae not coarse but very distinctly punctate, the inter- 

 vals distinctly carinate along the median line; male abdomen finely, feebly 

 punctate, with a rather large, deep medio-basal concavity and impressed 

 medial part of the fifth segment. Length 2.6 mm.; width i.i mm. Brazil 

 (Para). A single specimen, communicated by Desbrochers des Loges. 



carinulosa n. sp. 



Elytra more oblong, parallel basally, arcuately oblique to a rather more obtuse 

 tip from only behind the middle, their surface more densely opaque 2 



2 — Form narrower and more oblong suboval, densely opaque and devoid of lustre 

 above, piceous-brown in color, the fine sternal squamules more distinct, but 

 finer on the met-episterna than on the metasternum; beak in both sexes 

 opaque and much shorter than the prothorax, only feebly arcuate, rather 

 thick (cf), obviously thinner ( 9), the antennae well beyond the middle in 

 both sexes; prothorax slightly wider than long, the sides parallel and straight, 

 broadly rounding beyond the middle, sinuate just behind the truncate apex, 

 which is three-fifths to two-thirds as wide as the base and diaphanously 

 rufescent, the punctures strong, dense and longitudinally subconfluent, the 

 median line of the preceding species not apparent; elytra two-thirds longer 

 than wide, a fourth wider than the prothorax and much more than twice as 

 long, the humeri not distinctly tumid, oblique to the base; striae coarser
