Brazilian Barix.-e 141 



sharply defined channel. The beak is short and thick, peculiarly 

 sculptured and separated from the head by a well defined impressed 

 line, the antennae notably short, medial, the first funicular joint 

 about as long as the next three, the club oval, densely pubescent, 

 as long as the preceding four joints, gradually pointed and with 

 conspicuous sutures, the basal segment less than half the mass. 

 The mandibles are straight, coming together on a perfectly straight 

 line, which is scarcely modified, having medially only an almost 

 imperceptible nick. The femora are wholly devoid of the small 

 inferior spicule characterizing all the preceding genera, and the 

 tarsal claws are connate at base. The type is the following: 



Pseudogarnia obesula n. sp. — Rhomboidal, strongly convex, smooth, polished 

 and very deep black throughout; beak much shorter than the prothorax, thick, 

 moderately arcuate, strongly, closely sculptured, not much compressed, the distal 

 upper surface with close and longitudinally strigose sculpture and with a fine 

 distinct median carina: more basally the surface becomes smoother, with several 

 longitudinal lines of close-set punctures; prothorax a fourth wider than long, 

 the sides moderately converging, evenly and slightly arcuate from base to about 

 apical third or fourth, there becoming rapidly rounded and converging to the 

 very moderate and not very abrupt tubulation, which is three-sevenths as wide 

 as the base, its sides being oblique and not parallel; surface with minute sparse 

 punctulation, becoming strong and sparse punctures toward the sides, still coarser 

 and closer throughout the inferior flanks; basal lobe rather strongly rounded, 

 with a very minute and feeble sinus at the middle of the apex, the lateral impres- 

 sions wholly wanting; scutellum rather longer than wide, fiat, parabolic and 

 somewhat closely fitting the elytra, the latter very evenly oval, but little longer 

 than wide, a fifth or sixth wider than the prothorax and three-fifths longer, the 

 humeri not very prominent; grooves strong, deep, abrupt and nearly smooth, 

 not so coarse and slightly punctulate suturally; intervals flat, with minute 

 sparse punctulation in uneven single lines, the first and second near the scutellum 

 with very few slender whitish squamules; under surface strongly, somewhat 

 closely punctate, the abdomen more finely and sparsely, not modified in the type; 

 legs rather short. Length 3.7 mm.; width 2.45 mm. Brazil (Santarem). One 

 specimen, of undetermined sex. 



I know of no other generic type particularly allied to this, either 

 in the Brazilian or Central American faunal regions. 



Leptogarnia n. gen. 



In some respects this genus is allied to the preceding, as in the 

 absence of femoral denticles and the simple rounded external outline 

 of the tibiae basally, but the beak is altogether different, being 

 long, strongly sculptured, rather thick basally, very gradually 

 tapering thence to the tip, with the channel at the sides beyond 

 the antennae very long and conspicuous; it is separated from the 

 head by a rather feeble impression. The mandibles are much 

 shorter, prominent when closed and apparently with straight inner 

 lines; the anterior coxae are separated by fully their own width,
