500 RHYNCHOPHORA. 
8. Oxypteropsis bipartitus, sp.n. (Tab. XXIV. figg. 20, 20a.) 
Elongate-ovate, black, the antenn# ferruginous; clothed with small brown scales, with a few whitish or 
ochreous scales intermixed, the elytra with a dense, anteriorly dilated, patch of whitish or ochreous 
scales extending from the apex to near the middle and each with a minute whitish spot on the disc, the 
upper surface also somewhat thickly set with short, semierect setee, the legs setulose. Head densely 
punctate, the eyes large and narrowly separated ; rostrum very finely punctate, rugulosely punctured and 
squamose at the base ; joint 2 of the funiculus much shorter than 1. Prothorax transverse, constricted 
and narrowed in front ; densely punctate. Elytra much wider than the prothorax, subparallel in their 
basal third, broadly and strongly produced at the apex, the humeri rounded ; coarsely seriate-punctate, 
the interstices closely, minutely punctulate, 2 and 4 slightly raised posteriorly. Legs moderately stout, 
the femora almost linear and unarmed. 
Length 4-47, breadth 14-2 millim. 
Hab. Guatemaa, Cerro Zunil 4000 feet (Champion). 
Two specimens, probably male and female. This insect much resembles Euscepes 
truncatipennis, but the femora are unarmed, the prothorax is shorter and has the sides 
less rounded, the squamigerous scutellum is distinctly visible, and the elongate densely 
squamose whitish or ochreous apical patch is without intermixed broad scales. 
MICROXYPTERUS, gen. noy. 
Rostrum curved, stout, triangularly dilated at the base, the antennse inserted a little behind the middle, the 
funiculus 7-jointed, the club ovate, with distinct sutures; eyes large and not very widely separated ; 
prothorax transverse, somewhat rounded at the sides, bisinuate at the base, the ocular lobes almost 
obsolete; scutellum not visible; elytra convex, a little wider than the prothorax, ovate, laterally 
compressed and attenuate at the apex, 10-striate, the humeri rounded; mesosternum very prominent, 
arcuate-emarginate in front; metasternum moderately long, the episterna not visible; ventral segments 
2-4 subequal in length ; femora feebly clavate and minutely dentate ; tibia narrow, unguiculate at the 
outer apical angle; tarsi slender, joint 3 bilobed, the claws minute and approximate; body narrow, 
squamose and setose. 
Microxypterus includes two small species of peculiar facies, each having a large 
space at the sides of the elytra sparsely squamose or almost bare. They approach 
Oxypterus obliquus, but lack the prominent humeri; and the fasciculate vestiture of 
the elytra is here replaced by a row of long, scattered, erect setae on each interstice, 
The femoral tooth is narrow and minute. The humeri are less prominent than in 
Pseudomopsis. 
1. Microxypterus suturalis, sp.n. (Tab. XXIV. figg. 21, 21a.) 
Oblong-ovate, narrow, shining, nigro-piceous, the antenna, the tarsi, and the apices of the tibie more or less 
ferruginous, the elytra rufescent, with the sides darker ; the squamiform vestiture of the head ochreous, 
that of the prothorax ochreous and brown intermixed, except upon the white median vitta; the elytra 
w.th a posteriorly widened, dense, brownish-white sutural stripe, bordered externally by an interrupted 
blackish line, the rest of the squamosity much finer, more scattered, and ochreous, the interstices each 
with a row of long, fine, erect, scattered sete; the under surface and legs squamose, the latter also 
setulose. Head densely punctate, the eyes large and rather narrowly separated; rostrum widened and 
rugosely punctate at the base, and sparsely, finely punctate thence to the apex; joint 2 of the funiculus 
shorter than 1. Prothorax transverse, convex, rounded at the sides, narrowed and slightly constricted
