STICTOBARIS. 
Stictobaris, Casey, Ann. N. York Acad. Sci. vi. pp. 466, 516 (1892). 
Casey refers three species, from Texas, Arizona, and New Mexico respectively, to 
this genus, the type being Onychobaris cribrata, Lec., which extends into Mexico. 
‘They are all oblong, depressed forms, with the rostrum in both sexes short, stout, and 
abruptly arcuate, the prothorax strongly constricted in front and very coarsely punctate, 
the elytra rather broad and parallel-sided, the prosternum feebly impressed, the anterior 
cox separated by less than their own width, the tarsal claws divergent. |

Hab. Nort America, Waco? in Texas!.—Mexico, Acapulco, Jalapa (Hodge), 
Guanajuato (Sallé), Omilteme in Guerrero (H. H. Smith), Gonzales in Hidalgo 
(Wickham). 
The five specimens from Mexico agree so nearly with the above-quoted descriptions 
that there can be little doubt that they belong to Leconte’s species, the types of which 
were probably somewhat abraded. The Mexican insects are sparsely clothed with 
long, yellowish-white, decumbent, setiform scales, those on the prothorax condensed 
along the sides and middle, and those on the elytra into a spot on the shoulders, a 
streak at the base of the third interstice, and a transverse patch on the disc beyond 
the middle. The rostrum is short, stout, and closely punctate in both sexes, and the 
first and second ventral segments are slightly depressed down the middle in the male. 
S. pimalis, Casey (an example of which is before me), has the vestiture of the upper 
surface very much sparser than in S&S. cribrata. 
GYMNOBARIS, gen. nov. 
Mandibles short, notched within, slightly decussate at the tip; rostrum curved, moderately long, separated 
from the head by a deep transverse groove, the antenne inserted at or behind the middle, the antennal 
club pubescent, stout, oblong-ovate, about as long as joints 2-7 of the funiculus; prothorax transverse, 
constricted in front, bisinuate at the base, the median lobe slightly impinging on the scutellar cavity ; 
scutellum strongly transverse, flattened ; elytra oblong, flattened, finely striate; pygidium fully exposed, 
small in the 2, larger in the ¢; prosternum convex or flattened, neither suleate nor foveate behind the 
transverse subapical groove, the basal process declivous laterally; mesosternum exposed, connate with 
the metasternum, the intercexal portion on almost the same plane as the prosternum; anterior coxe 
distant, separated by at least their own width; ventral segments 1 and 2 connate at the middle; femora 
more or less clavate, not sulcate beneath (except at the knees), the anterior pair sometimes with a short 
tooth ; tarsi rather slender, the claws free ; body elongate or oblong-ovate, flattened above, polished, 
almost glabrous. 
Type, G. brevidens. 
This genus includes two species from Central America, and Baridius nigerrimus,
