Brazilian Baring 34 1 



almost smooth, nea'rly four-fifths as long as the elytra; antennae blackish inserted 

 near basal third; prothorax about as long as wide, somewhat wider behind the 

 middle than at base, the sides broadly arcuate, the tubulation somewhat more 

 than half as wide as the base, the basal lobe small, very short and broadly rounded; 

 elytra three-fourths longer than wide, a fourth wider than the prothorax and 

 nearly twice as long, ogival in about apical half, the sides thence straighter and 

 feebly diverging to the feebly swollen humeri; grooves very feebly punctulate, 

 only about a fifth as wide as the intervals, which are entirely smooth; first ab- 

 dominal suture extremely fine. Length 5.8 mm.; width 2.35 mm. Venezuela 

 (Caracas). 



The type was received from Desbrochers des Loges under the 

 title " Daclylocrepis ebeninus Db." I have preserved the specific 

 name which is probably unpublished. 



Theantis n. gen. 



This genus is evidently related to the preceding, but differs very 

 much in the form of the basal thoracic lobe, scutellum, antennae and 

 in sculpture. The body is rhombic-oval and glabrous above, each 

 puncture of the under surface with a minute slender squamule. 

 The beak is slender, smooth, cylindric and evenly arcuate in both 

 sexes, separated by a subobsolete impression and with the mandibles 

 dentate and similarly decussate. Antennae at basal third (o 71 ) or 

 slightly behind this point (9), long, slender, with the first two 

 funicular joints long and subequal, the seventh somewhat longer 

 than wide, not so similar to the club in pubescence as in the pre- 

 ceding genus, the club much smaller, but little longer than the two 

 preceding joints, its basal segment more than half the length, the 

 remainder forming a regular cone, the sutures similarly distinct; 

 the scrobes are subsimilar, the scape shorter and more gradually 

 clavate. The prosternum is even, separating the coxae by twice 

 their width and, in the male, has two short porrect spines at a third 

 of the distance from coxae to apex, the part beyond the line of the 

 spines rapidly inclining upwardly and smooth, but not impressed. 

 The legs are long and rather slender, and the tarsal claws arcuate 

 and divergent, but very much shorter and feebler than in the 

 preceding. The prothorax is tubulate at apex, the basal lobe 

 rapidly formed, long, prominent and rounded at tip, the scutellum 

 very small, not so free, transverse, and the elytra with series of 

 distinct punctures in very fine obsolescent striae suturally, becoming 

 coarse grooves laterally and also at apex, the intervals flat even at 

 apex, not cariniform posteriorly as in the next genus. 



This genus is probably allied to Eutoxus Schon. (type reflexus), 

 but there is no trace of pygidium in either sex. 



The species known at present are three in number, as follows: 



Body rhombic-suboval, convex, shining, piceo-rufous, the under surface, legs and 

 beak blacker; beak strongly, evenly arcuate in both sexes, about as long as
