Brazilian Barinle 99 



It is probable that these species are truly congeneric with the 

 type described by Solari, although no definitive mention of the 

 antennal club is included by the author; the generic relationships 

 are therefore more or less in the nature of a surmise. 



Trinacria n. gen. 



The body here has very nearly the same parallel and convex 

 form as in the preceding, but the system of sculpture and ornamen- 

 tation is different, besides the rather radically different mandibles, 

 as before stated. The beak in the male is rather short, thick, 

 feebly arcuate, not separated from the head above and with the 

 antennae greatly beyond the middle, and, in the female, not differing 

 very much, but more slender and with the antennae more medial. 

 The prosternal canal is only well defined before the coxae, and is 

 not inclosed by high lateral walls as it is in Ccelonertus; it is not at 

 all defined behind the moderately separated coxae. The two known 

 species may be defined as follows : 



Body narrow, parallel, convex, deep black and moderately shining, the legs 

 piceo-rufous and slender, the beak more or less rufescent at apex; whitish 

 squamules above minute, sparse and inconspicuous, a little more distinct 

 on the elytra medially at apical fourth, and becoming dense conspicuous 

 scales on the intervals in basal sixth and also at the hind angles on the pro- 

 notum; beneath they are fine and sparse, but in the form of dense scales on 

 the met-episterna; beak moderately thick, much shorter than the prothorax 

 in both sexes, the prothorax strongly convex when viewed in profile, as long 

 as wide, the sides parallel and straight to somewhat beyond the middle, there 

 rounded and thence oblique and feebly subsinuate to the apex; punctures 

 coarse, deep and not quite in mutual contact; scutellum subquadrate, small, 

 impressed and glabrous; elytra three-fifths longer than wide, barely visibly 

 wider than the prothorax and two-thirds longer, the sides parallel and straight 

 in about basal half, thence arcuately converging to the narrowly rounded 

 apex; striae deep, punctulate, fine apically, gradually rather coarse basally; 

 intervals twice as wide as the striae, each with a single series of small distant 

 punctures. Length 2.2-2.35 mm.; width 0.75-0.85 mm. Brazil (Santarem).

Body much larger, subparallel though rather more ventricose, convex, somewhat 

 shining, the pronotum alutaceous; color dark red-brown; yellowish-white 

 squamules above small, sparse and inconspicuous on the pronotum, coarser 

 but sparse at the hind angles; on the elytra they are coarse and distinct in 

 single lines, becoming gradually confused at base and almost wanting through- 

 out on the flanks, fine but rather long and abundant beneath, coarser on the 

 presternum and dense also on the met-episterna; beak (cf) thick, closely 

 and finely sculptured, straight, bent a little apically and three-fifths as long 

 as the prothorax, the antennae near distal third; prothorax convex, rapidly 

 sloping at apex when viewed in profile, as long as wide, the parallel sides 

 feebly arcuate for two-thirds, then rounding and sinuously oblique to the 

 truncate apex, much more than half as wide as the base; punctures moder- 

 ately coarse, uneven, separated by once to three times their diameters; scu- 

 tellum elongate, parallel and deeply canaliculate; elytra only one-half longer 

 than wide, distinctly wider than the prothorax and two-thirds longer, parallel,
