BARINiE 509 



abdomen at base between the coxae, where there are sparse and rather 

 strong punctures, each enclosing a minute scale; beak in the male very 

 thick, cylindric, smooth and rather shining, finely, somewhat closely 

 punctate, evenly, moderately arcuate and nearly as long as the head 

 and prothorax, the antennae at about the middle; prothorax large, almost 

 as long as wide, the sides converging and straight for three-fifths, then 

 rounded, becoming sinuously oblique to the apex, which is half as wide 

 as the base, constricted and tubulate only beneath; base broadly, evenly 

 arcuate from side to side; punctures extremely minute and remote, 

 becoming more visible toward apex; elytra a fourth longer than wide, 

 inflated, with rounded sides near basal fourth, and there a fourth wider 

 than the prothorax, fully three-fourths longer, the sides behind basal 

 fourth oblique and broadly arcuate to the narrowly rounded apex; striae 

 fine and extremely feeble, almost obliterated, but with very large, widely 

 spaced and conspicuous punctures, the intervals with extremely minute, 

 sparse and confused punctures; male with the abdomen broadly, feebly 

 impressed and strongly punctured at base; tibiae with coarse fulvous 

 decumbent vestiture internally. Length (cf ) 3-5 mm.; width 2.0 mm.

This is one of the remarkable apterous rhomboidal species, such 

 as Oomorphidius and Eisonyx; they are probably the remains of a 

 very ancient fauna, and, at the present time, nearly all that are 

 known constitute monotypic genera. The upper profile of the body, 

 viewed from the side, is strongly and evenly arcuate from front to 

 elytra! apex, in this species more strongly so than in Oomorphidius 

 erasus, a specimen of which, from Iowa, is now in my collection. 



Zygobarella n. gen. 

 In this genus the body is small in size, oval, rather coarsely 

 sculptured and subglabrous, the elytra with remotely scattered 

 linear white scales. In the last-named feature, as well as in the 

 general structure of the beak, mandibles and prosternum, as well 

 as in the connate tarsal claws, it resembles Zygoharis Lee, but in 

 the type of elytra! sculpture, form of the distal parts of the antennae 

 and in the much smaller body, it differs conspicuously. The outer 

 part of the antenna! funicle does not merge gradually into the out- 

 line of the club as it does in Zygobaris, but the club is abrupt in 

 formation and its basal joint is not a third the total length as in 

 that genus, but fully one-half the mass or only slightly less. The 

 elytral striae are coarser, and are finely to obscurely punctate along 

 the bottom, and not fine, with very large punctures as in Zygobaris; 

 the interstitial sculpture, also, is altogether different. The type
