EUXENUS. . A495 
from the base yellowish-white, and the base broadly and indeterminately ochreous, the legs and under 
surface pale brown, the femora subannulate ; the upper surface also set with short, stout, clubbed setz, 
which are blackish and crowded on the prothorax (except down the middle) and scattered on the elytra. 
Head densely punctate; the eyes moderately distant; rostrum thickly punctate in the J, more sparsely 
so inthe 9. Prothorax transverse, densely, rather coarsely punctate. Elytra considerably wider than 
the prothorax, convex, subparallel in their basal half, the humeri obtuse, oblique in front; coarsely 
seriate-punctate. Femora unarmed. 
Length 44-53, breadth 2-23 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Four specimens. Very near EZ. apicalis, but with the humeri less prominent, the 
seriate punctures of the elytra closer and not so coarse, and the elytra themselves with 
a yellowish-white, sharply defined, streak extending for a short distance down the 
suture at the base, this not being connected with the apical patch as in E. apicalis. 
3. Huxenus ovatipennis, sp. n. (Tab. XXIV. figg. 12, 12a.) 
Extremely like Z. subparallelus, but with the elytra rounded at the sides, and at the base very little wider 
than the prothorax, the ochreous or yellowish-white streak at the base of the suture a little less extended 
posteriorly, the rest of the vestiture between the base and the apical declivity reddish-brown, becoming 
darker posteriorly. Femora unarmed. 
Length 44-43, breadth 22 millim. (d¢ 2.) 
Hab. Guatemata, Las Mercedes and Dueiias, Pacific slope (Champion). 
Five specimens. This insect is coloured almost exactly as in E. subparallelus, from 
which, and from F. apicalis also, it differs in having the elytra rounded at the sides. 
At first sight, Z. ovatipennis would appear to be an apterous form of £. subparallelus, 
but this is probably not the case. 
4, Buxenus rhombifer, sp. n. (Tab. XXIV. figg. 13, 13.) 
? Collabismus sellatus, Schénh. Gen. Cure. viii. 1, p. 400 (nec Boh.) *. 
Subovate, black, the antenne ferruginous; the prothorax clothed with coarse, intermixed brownish and black 
scales, the black scales erect and setiform and clustered into two fascicles at the apex, and with a small 
whitish v-shaped mark at the base; the elytra densely squamose, whitish or brownish-white, blackish 
along the basal margin, with a common, transverse, dark brown or blackish, rhomboidal patch on the 
dise, and also set with widely scattered, short, clubbed, erect, seriately arranged sete; the rest of the 
vestiture ochreous or brownish, intermixed with white, the legs setulose. Head densely punctate, the 
eyes large and not very widely separated; rostrum rugulose at the base and thickly punctate thence to 
the apex. Prothorax transverse, densely punctate. Elytra nearly one-half wider than the prothorax, 
convex, subtriangular, the humeri obtuse, oblique in front; coarsely seriate-punctate, the interstices 
somewhat convex. Femora unarmed. 
Length 4-44, breadth 14-2 millim. 
Hab. Muxtco (Hogberg'), Teapa (H. H. Smith), Temax in N. Yucatan (Gaumer). 
Two specimens. Readily recognizable by the densely squamose whitish elytra, 
which have a large, common, blackish, rhomboidal patch on the disc. ‘This insect is 
extremely like Collabismus sellatus, Boh., but the latter is larger, and has exposed 
metathoracic episterna, a longer prothorax, more closely setose elytra, &c.
