fine median line, confused on the strial intervals and scutellum and closer and 

 whiter beneath, except anteriorly; beak thick, moderately arcuate, sculptured, 

 dull and also setulose almost throughout, as long as the prothorax ( 9 ), a little 

 shorter (o 71 ); prothorax (o 71 ) rather small, conical, scarcely a fifth or sixth wider 

 than long, the sides converging and evenly, very moderately arcuate through- 

 out, or ( 9 ) much larger, a third wider than long, with the nearly straight sides 

 feebly converging, broadly rounding and more converging apically, the apex 

 non-tubulate and only about a third as wide as the base in both sexes; punctures 

 dense; base transverse, the lobe small, rounded; scutellum moderate, subquadrate 

 and free; elytra triangular, with strongly arcuate sides and very narrow apex, 

 with deeply reentrant sutural angle, only a fourth or fifth longer than wide, 

 evidently wider than the prothorax but much less than twice as. long, the grooves 

 very coarse, punctured along the bottom. Length 2.4-2.6 mm.; width 1. 3-1. 55 

 mm. Brazil (Santarem). Two specimens. 



In the male, the abdomen is feebly impressed medio-basally but 

 not notably different in vestiture, the fifth segment with a large 

 subglabrous median area. The sexual differences in the prothorax 

 are unusual and very marked. 



Calorida n. gen. 



This genus has straight non-decussate mandibles, prominent when 

 closed, the rather slender, smooth cylindric beak separated from 

 the head by a very shallow reentrant angle and with slender medial 

 antennae, having the first funicular joint very long, nearly equal to 

 the next three, although both the second and third are sensibly 

 elongate, the club small, oval, abrupt, as long as the three preceding 

 joints, with the first segment much less than half the mass. The 

 prosternum is abruptly canaliculate, but with the sulcus closely 

 squamose like the rest of the surface, and behind the narrowly 

 separated coxae it is bituberculate. The femora are very moderate 

 in thickness and unarmed, and the lobes of the third tarsal joint 

 are broad and oval, the diverging claws moderate. The arrange- 

 ment of the scaly vestiture is peculiar, as will be noted in the follow- 

 ing description of the only known species: 



Calorida binocularis n. sp. — -Body somewhat broadly ovoidal, deep black 

 throughout, closely squamulose above, the pronotum with rather dense parallel 

 yellowish and uniform scales, except in an abrupt rounded basal spot at each 

 side at outer fourth, where the scales are blackish and narrower; on the elytra 

 the long scales are nearly white, dense throughout the first interval as well as 

 scutellum, on 2-4 in an oblique subapical area, on the fifth and sixth from base 

 to apical fifth, on the seventh in a line from the middle to apical fourth, and on 

 the marginal interval in a short line near the base, elsewhere deep black and with 

 narrow blackish squamules; under surface with dense white scales throughout; 

 beak ( 9 ) moderately slender, gradually and slightly thicker basally, evenly and 

 not strongly arcuate, very smooth, black, polished, with minute and remote 

 punctulation, becoming strong and close and with small pale squamules at the 

 extreme base, and nearly three-fourths as long as the elytra; head polished, 

 nude and finely, sparsely punctate; prothorax short, nearly twice as wide as 

 long, the sides strongly arcuate, subparallel basally, oblique anteriad, strongly
