382 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 95 
Hemelytra coarsely punctate, veins on clavus and corium and 
apical margin of corium yellow; embolar margin broadly convex, 
length 2.95 mm.; cuneus small, impunctate, length 0.8 mm., width 
0.8 mm., reddish yellow, exterior margin dark brown; membrane 
dark brown, rugulose, inner apical angle of major areole acutely 
angulate. 
Propleura coarsely punctate, mesopleura and metapleura finely punc- 
tulate and rugulose. Xyphus, ostiolar peritreme, venter and legs 
yellowish brown. Length of posterior femora 2.45 mm., length of 
posterior tibiae 3.55 mm. 
Differs from all the known species by the unusual coloration, length 
of rostrum, and size of the body. 
Types.—U.S.N.M. No. 56724, holotype, female, Sandakan, Borneo 
(Baker) ; paratypes, 11 females, same data as holotype; 9 females, — 
Island of Basilan (Baker). 
Note.—I have before me a few male specimens collected from the 
same locality as the type. ‘They are very similar to this species in col- 
oration but are so much smaller that I prefer to await study of 
additional material before placing them with certainty. 
RHINOPHRUS, new genus 
Body elongate, shining, clothed very sparingly with simple hairs. 
Head small, horizontal, a little wider than the apex of pronotum, 
seen from above about one and one-half times as long as wide, seen 
from side longer than high; vertex immarginate, narrower than the 
width of eye seen from above, destitute of longitudinal sulcus; frons — 
horizontal, strongly produced into a cone-shaped process over clypeus; 
clypeus compressed, very prominent; bucculae united behind. Eyes 
large, granulate, occupying whole height of head, seen from above 
not prominent, far removed from apex of pronotum, anteocular part 
longer than postocular part. Antennae linear, shorter than the 
length of body, inserted at the middle of anterior margin of eyes, first 
seoment thickest, second slightly thickened at apex. Rostrum gradu- 
ally tapering toward apex, reaching upon intermediate coxae. 
Pronotum horizontal, finely transversely rugulose, wider than long, 
over twice as wide at base as at apex, strongly widened behind calli, 
lateral margins vertically rounded, posterior margin broadly sinuate 
before scutellum; apical collar flat; calli flat, confluent. Mesoscutum 
widely exposed, scutellum triangular, flat, wider than long. 
Hemelytra complete, embolar margins nearly parallel, cuneus hori- 
zontal, longer than wide, fracture distinct; membrane well developed, — 
unicellulate. 
Xyphus with disk flat, lateroposterior margins elevated; ostiolar 
peritreme small. Last dorsal segment produced in both sexes. Legs
