BARIS. 469 
very gradually narrowing from the obtuse humeri; deeply punctate-striate, the interstices broad, 
flat or feebly convex, finely uniseriate-punctate, the third confusedly punctured, the ninth raised towards 
the apex. Beneath closely, the abdomen sparsely and finely, punctate; metasternum and first ventral 
segment deeply excavate, and the apical margin of the fifth segment distinctly thickened in the middle, 
in the g. Prosternum slightly depressed along the middle. Anterior coxe separated by less than 
one-third of their own width. Tibie almost straight, the anterior pair with a long apical uncus in 
the ¢. 
Length 32-4, breadth 14-2 milim. (<.) 
Hab. Mexico, Toxpam, Jacale (Sallé), Orizaba (1. H. Smith), Cerro de Plumas, 
Oaxaca (Hoge). 
Seven specimens, all males. A large, oblong form of B. wrea, with the upper 
surface very finely alutaceous, the prothorax closely punctate, the elytra rather coarsely 
and deeply punctate striate, the interstices sometimes feebly convex, and the ventral 
excavation of the male deep. It seems to require a separate name. Bb. subsimilis, 
Casey, resembles B. fratruelis, but is less oblong and has the abdomen much more 
closely and coarsely punctured. 
5. Baris corrusca. 
ious corruscus, Boh. in Schénh. Gen. Cure. viii. 1, p. 140°. 
Hab. Mexico! (Mus. Brit.), “Sierra de Durango” (f/oge, in coll. Solari ), Guanajuato 
(Sallé), Yucatan (Mus. Brit.). 
This insect is only separable from B. wrea by its rather more elongate form, the 
more closely punctured prothorax (except along the median line) and elytra, and the 
larger and more conspicuous setiform scales on the interstices of the latter. ‘The 
specimens from Guanajuato seem to belong to a distinct species, while on the other 
hand many of those from Guatemala city here referred to B. wrea are more or less 
intermediate.
