Brazilian Barinle 505 



usual fine subapical constriction, separating the coxae by two-thirds 

 their width, the intercoxal suture distinct. Prothorax short, not 

 tubulate, although the dorsal surface at apex is feebly impressed, 

 the truncate base feebly and obtusely cuspidulate at the middle; 

 scutellum free, oblong, parallel and longer than wide. Elytra with 

 rather coarse striae, the legs normal, the femora scarcely inflated; 

 tibiae but little shorter than the femora, the tarsi moderate, the 

 first two joints rather narrow, the third subcircularly inflated and 

 the claws moderate, free and divergent. The type is the following: 



Canopinus rectirostris n. sp. — Oblong-suboval, shining, deep black throughout 

 and glabrous above; beak (c?) straight, as long as the head and prothorax, 

 sparsely punctate and somewhat squamulose, or ( 9 ) a fourth longer, thinner and 

 sparsely punctate, slightly squamulose at the sides basally; antennae slender, 

 nearly black; prothorax transverse, two-fifths wider than long, somewhat wider 

 just behind the middle than at base, the sides strongly, almost evenly arcuate, 

 converging gradually from about two-thirds, the apex truncate, much less than 

 half as wide as the base; punctures rather coarse but not very deep, narrowly 

 separated at the sides, more so anteriad, smaller and sparse in basal four-sevenths, 

 the narrow median line not well defined but just visibly subprominent by oblique 

 light; elytra one-half ( 9 ) to four-sevenths (c?) longer than wide, at the middle 

 widest and evidently wider than the prothorax, nearly two and one-half times 

 as long, the sides parallel and broadly arcuate; apex rather rapidly and obtusely 

 rounded; striae strong, somewhat impressed, closely and moderately punctate, 

 not much coarser at apex; intervals four to five times as wide as the striae, not 

 quite flat and each with a single series of moderately coarse, close-set punctures; 

 under surface rather strongly and loosely punctate, the prosternum somewhat 

 coarsely so, the abdomen with a moderate impression medio-basally (cf), the 

 last segment short, transverse and densely clothed in both sexes. Length 4.65- 

 5.2 mm.; width 1.85-2.25 mm. Brazil (Obidos, Amazonas). Rolle. Four 

 specimens. 



At first it seemed as though this genus might be the Parallelosomus 

 of Schonherr, but on closer observation it becomes obvious that 

 there can be no close resemblance. 



To one desiring to identify a miscellaneous lot of genera and 

 species in this subfamily, the proper references may seem almost 

 impossible of attainment, except after prolonged study of the entire 

 series, and it is therefore proper to throw out a few hints, which 

 may serve to point the way to the tribal group most likely to include 

 such isolated material, as follows: 



If the anterior coxae be contiguous or nearly so and the femora 

 denticulate, the unknown genus may pertain to one of the first three
