Brazilian Barin^e 113 



black throughout; beak long, arcuate, cylindric, feebly compressed and more 

 punctate at the sides basally, sparsely and very moderately punctate and nearly 

 as long as the elytra, the antennae medial, the second funicular joint even some- 

 what longer than the first, the club narrow, long and very gradually, sharply 

 pointed, finely, densely pubescent, the basal segment fully half the mass; pro- 

 thorax one-half wider than long, the sides subevenly arcuate, becoming parallel 

 basally, tubulate at apex, impunctate; elytra scarcely as long as wide, triangular, 

 with rounded apex and very feebly arcuate sides, the humeri very prominent, 

 with shining summit; striae very fine, minutely, remotely subpunctulate, the 

 first four dilated at base; intervals very flat, impunctate; femora acutely spicu- 

 late and with a few minute serrules beneath beyond the middle. Length 7.6-8.5 

 mm.; width 5.7-6.2 mm. Brazil (Rio de Janeiro). Three males, the female 

 not at hand. 



The prosternum in the male has a very deep rounded excavation 

 between the two short, slender and somewhat contorted ante-coxal 

 spines, the coxae separated by four-fifths their width. The under 

 surface of the body throughout has fine and remote punctures. 



The species described by Solari (Ann. Mus. Civ., Genova, XLII, 

 p. 438) under the name Camelodes pascoei, it seems to me, may quite 

 possibly prove to form a distinct though allied genus; the body is 

 strongly shining throughout. 



Stegotes n. gen. 



This genus is composed of a very large number of polished, 

 glabrous, rhomboidal species, resembling each other so closely in 

 external appearance in some parts of the series, that any exposition 

 of them affording a sure means of identification, in the absence of 

 actual types, is practically an impossibility. Numerous Mexican 

 Stegotes were described as members of the genus Diastethus by 

 Mr. Champion, but, in common with Gladosius, they are readily 

 distinguishable from that genus by the sharply canaliculate pro- 

 sternum and lack of abruptly defined patches of dense scales beneath. 

 In both Gladosius and Diastethus , the body in most of the species 

 is of a brilliant metallic color, while no such feature is anywhere 

 discernible in Stegotes, the only variation from a uniform and 

 intense black being the rufous prothorax of a number of species. 

 The body is never quite as large as in Camelodes, and, in some 

 species, is moderately small in size. I have endeavored below to 

 separate the many species at hand as carefully as possible, but fear 

 with only moderate success as an aid to identification ; it is wholly 

 useless to attempt to identify any of them surely with the species 

 published by Schonherr, which, however, do not seem to be numer- 

 ous: 



Body deep black and shining throughout 2
