Not uncommon in Chiriqui, whence we possess ten examples. The types of Stal’s 
and Walker’s species have been seen. In this species the pronotum is opaque, often 
with a slight violaceous lustre, with the sulci on the anterior lobe (except the median 
one posteriorly) very shallow. The ochraceous or whitish elytral markings show little 
sign of variation: there is a small spot adjoining the apex of the scutellum, a transverse 
spot a little below the base of the membrane, and a short A-shaped streak near the 
apex of the corium. A Chiriqui specimen is figured. 
7. Rasahus bifurcatus, n. sp. (Tab. XIII. fig. 11, ¢ .) 
Moderately elongate, opaque, nigro-piceous or black ; the elytra with a broad ochreous stripe extending along 
the clavus and inner portion of the corium to beyond the base of the membrane, and then bifurcating 
and continued for some distance along its inner and outer margins, the outer branch following the 
direction of the outer nervure to near the tip and usually with a narrow ramus extending backwards 
along the median nervure at its point of termination (forming a hook-like mark); the abdomen slightly 
shining above, the connexival segments opaque, each with a broad ochraceous patch at the base; the 
legs piceous or nigro-piceous, the intermediate and hind femora each with a flavous ring at the base, the 
tarsi fusco-testaceous ; the antenne piceous, with the basal joint black and the tip of the second joint 
ochraceous ; the head, pronotum, antenne, and legs with a few widely scattered, long, fine, projecting 
hairs. Antenne with joints 2-4 subequal in length, 1 less than half the length of 2. Pronotum much 
longer than broad, both lobes obsoletely margined laterally ; the anterior lobe rounded at the sides, twice 
as long as, but much narrower than, the posterior lobe, the disc broadly and very shallowly trisulcate 
down the middle and with two very shallow oblique sulci on each side, the sulci and the lateral margins 
closely granulate, the median sulcus becoming very deep at the base; the posterior lobe closely and 
conspicuously granulate, with the obtuse hind angles moderately prominent; the anterior angles 
tuberculiform and very prominent. Scutellum granulate, the spiniform apical process compressed and 
semierect. Elytra comparatively short, reaching to about the middle of the sixth abdominal segment in 
the male and to a little beyond the apex of the fourth segment in the female. Abdomen oval, very much 
wider than the pronotum, rounded at the apex in the female and broadly subtruncate in the male; the 
connexivum broad, in the male extending broadly round the apex of the abdomen. (Pro-, meso-, and 
metapleura granulate, the venter smooth. Anterior tibie with the spongy fossa extending to nearly 
two-thirds of its length. Posterior tarsi with the third joint a little shorter than the two others 
united. 
Length 123-14; breadth of the pronotum 3, of the abdomen 4-4} millim. (¢ 9.) 
Hab. Panama, Volcan de Chiriqui, Caldera (Champion). 
Four specimens, two of each sex. Allied to &. flavovittatus, Stal (=vittifer, Walk.), 
from Colombia, but differing from it in the unusually short elytra in both sexes, the 
‘more prominent anterior angles of the pronotum, the spotted connexivum, and the 
extended and subtruncate apex of the latter in the male. When the elytra are closed
