2o6 MEMOIRS ON THE COLEOPTERA 



but prominent, at much more than their own length from the base, the 

 tempora equally prominent, parallel, arcuate, broadly rounding and then 

 strongly converging at base; antennae moderately short, infuscate, 

 pale and slender basally, rapidly incrassate in about apical half only, 

 the first three joints slowly diminishing in length and thickness, the 

 fourth as long as wide, tenth fully twice as wide as long, obtrapezoidal, 

 the last conoidal and longer than the two preceding; prothorax nearly 

 four-fifths wider than long, widest at the middle, the sides evenly and 

 strongly arcuate throughout, the basal angles very obtuse and rounded, 

 the transverse basal impression obsolescent; elytra much shorter than 

 wide, equal in width to the prothorax and a third longer, the sinuses small 

 and moderate in depth; abdomen rather broad, parallel, almost as wide as 

 the elytra, the three impressions rather fine but distinct. Length 1.5 mm. ; 

 width 0.4 mm. California (mountains near Claremont), Baker. 



Readily distinguishable from pasadence, which inhabits almost 

 the same locality, by its more strongly, more rapidly and more 

 distally incrassate antennae and very much more strongly rounded 

 sides of the prothorax; there are no sexual marks visible in the type, 

 which is probably a female. 



Subgenus Ulitusa Csy. 



The chief distinction of this group, when compared with either 

 of the two preceding, lies in the remarkable sculpture of very coarse 

 deep rounded punctures; but, as the structural characters do not 

 materially differ, it seems best to regard it as a subgenus for the 

 present. The type is Ulitusa cribratula Csy., (Tr. Acad. St. Louis, 

 XVI, p. 348). It was described from near Cincinnati, but last 

 summer I found it under old chestnut bark, on the Blue Ridge at 

 Buena Vista Spring, Penn., together with Leptusa opaca. 



Crimalia n. gen. 



In all of the preceding allies of Leptusa, the infra-lateral carinae 

 of the head are strongly, generally conspicuously developed and 

 always entire, this being one of the most constant features of that 

 group of genera and subgenera; in the minute species for which the 

 above name is suggested, however, there is no vestige of the carinae 

 at any part of the cephalic flanks. The antennae are nearly similar, 

 excepting a relatively greater thickness of the two basal joints, the 

 eyes well developed, the hypomeraand tarsi as in Leptusa; but the 

 mesosternal parts are different, the interval between the moderately 

 long and rather obtusely pointed mesosternal process and the
