Not uncommon in the Mexican State of Vera Cruz, some specimens having the 
elytra obsoletely striato-punctate (A. bonvouloiri) and others the elytra finely but 
distinctly punctate-striate (A. mexicanus). The prosternum in both sexes is more or 
Jess fulvo-pilose along the middle (the sulcus included) from the apex to the base, the 
vestiture being abundant behind the anterior coxe. The male has a very large oval 
depression on the first ventral segment. ‘The antenne are inserted towards the apex 
in both sexes. I have seen the types (¢ 3) of Kirsch and Solari; the locality “ Sierra 
Durango,” quoted by the last-mentioned author 2, requires confirmation. 
LEPTINOBARIS, gen, nov. 
Mandibles short, decussate; rostrum moderately long, arcuate, cylindrical, the antenne inserted beyond the 
middle, with joints 2-7 of the funiculus short and closely articulated, and the club ovate; prothorax 
feebly sinuate at the base; scutellum oblong, subquadrate, flat; elytra elongate, conjointly rounded at 
the apex; pygidium short, exposed, vertical; prosternum with a shallow, parallel-sided sulcus, which 
extends forwards to the apex and terminates in the v-shaped space between the narrowly-separated, 
rather small anterior coxe, the basal portion very short and depressed; mesosternum depressed, 
exposed ; metathoracic episterna narrow ; ventral segment 5 very little longer than 3 or 4,1 and 2 
connate; legs short; femora unarmed, the anterior pair feebly clavate; anterior tibix (¢ ) strongly 
bi- (fig. 27 5), and the others feebly uni-, unguiculate; tarsal claws minute, connate at the base ; body 
narrow, subcylindrical, polished. 
Type, LZ. bidens. 
The type ot Leptinobaris is of the same general shape as Stenobaris avicennia, Linell, 
which also has narrowly separated anterior coxee; but the two genera are not otherwise 
very Closely related. The strongly biunguiculate anterior tibiz is a striking character, 
and one that is also to be found in the male of “ Centrinus” suspensus, Boh., an 
insect probably belonging to the genus Anopsilus. Microbaris, Casey, based upon 
a minute Texan insect, seems to be nearly related to Leptinobaris. 
1. Leptinobaris bidens, sp. n. (Leptobaris bidens, Tab. XX. figg. 27%, 
27 a,b, 3). 
Very shining, black, the antenne and tarsi ferruginous ; almost glabrous above, the prosternum (including 
the sulcus) and metathoracic episterna somewhat thickly, and the rest of the under surface very sparsely, 
clothed with narrow hair-like whitish scales. Head very sparsely, minutely punctate, faintly foveate 
between the eyes; rostrum nearly as long as the head and prothorax, rather slender, very sparsely, 
* The insect is narrower and more cylindrical than represented on the Plate. The generic name Leptobaris 
proves to be preoccupied.
