narrowly rounded; the strong, transverse, basal constriction noted in the pre- 

 ceding, wholly wanting, the neck and the occiput being continuous ; front 

 separated from the clypeus by a strongly impressed arcuate line, a distinct 

 median impression on the vertex ; antenna! tuberculations strong, antennae 

 slightly longer than the head and thorax, about the length of the terminal 

 joint, rather strongly incrassate distally, second joint about one half longer 

 than wide, third slightly elongate, four to eight subglobular. increasing grad- 

 ually in size, nine and ten larger, ten slightly transverse, terminal joint about 

 one third longer than wide and obtusely rounded at apex, antennae strongly 

 pubescent. Thorax thne fifths wider than long, slightly narrower than the 

 elytra, widest at apical third, narrowed anteriorly and posteriorly, posterior 

 angles distinct though rounded, base rounded, apex less rounded, disk with a 

 distinct, longitudinal impression cither side extending nearly the length of the 

 thorax, widened basally. Elytra about a fifth longer than wide and nearly 

 twice as long as the thorax, sides straight. Abdomen gradually wider to the 

 apex of the fourth segment, where it is the widest part of the body ; four basal 

 segments strongly micro-reticulate, indistinctly and sparsely punctate, mod- 

 erately shining, fifth segment very strongly shining, reticulation less distinct, 

 four basal segments with an apical row of long, coarse, fulvous hairs which lie 

 flat on the segments, apex of the fifth segment with a very dense fringe of 

 very short, pale, yellowish hairs, broadly and shallowly cmarginate, sixth seg- 

 ment deeply emarginate with lateral projections. Length 1.7 mm., width .4 

 mm. I specimen. 

 Type 21 May.

Lathrobium lintneri new species. 



Form rather slender, parallel, head, thorax and elytra subequal in width, 

 abdomen slightly wider at the apex of the fourth segment; the sexes not dif- 

 fering at all in proportions. Color black, antennae and legs pale piceo-rufous, 

 narrow apical margin of the elytra pale. Head coarsely, deeply and somewhat 

 sparsely punctured, thorax similar in punctuation with a median smooth area 

 equal in width to the length of the fifth antennal joint. Elytral punctuation 

 finer, subasperate and about as sparse. Abdomen densely and finely punctate. 

 Head about as wide as long, sides parallel and arcuate, posterior angles broadly 

 rounded, gular sutures well separated, straight and parallel ; antennae slender, 

 not quite reaching the base of the thorax (cj) shorter ($) joints all distinctly 

 longer than wide and obconic ((^) ; in the female the tenth joint is about as 

 wide as long ; they decrease regularly in length to the tenth, the terminal 

 slightly longer. Thorax one fourth longer than wide, as long as the elytra, 

 sides scarcely arcuate or convergent posteriorly. Elytra with the sides very 

 slightly divergent posteriorly and scarcely arcuate. Posterior tarsi slender.
