LAMUS. —THYMBREUS. 211 
front (including the carins), obscure reddish-ochreous ; the scutellum with the two carine and the apical 
process rufous ; the elytra sordid ochreous, the corium with the apical nervure, a spot: near the base, and 
two narrow, partly connected, angulated fascie black, the membrane with the entire inner half much 
mottled with fuscous, and with a large similarly coloured patch at the base of the outer discal area; the 
connexivum reddish-ochreous, each segment with the basal margin and a subquadrate median lateral patch 
black ; the basal joint of the antenne ferruginous above; the femora each with a narrow annulus at the 
apex, and the upperside more or less to near the tip, rufo-ferruginous; the legs and antenna pilose, the 
three outer joints of the latter also with long fine projecting hairs. Head much shorter than the pronotum, 
the anterior lobe stout, parallel, and a little shorter than the posterior lobe, the antenniferous processes 
short, about half the length of the very large and prominent eyes, the post-ocular portion very short, the 
ocelli large and prominent ; antenne with joint 1 about reaching the tip of the apical process of the head, 
2 more than three times longer than 1, 3 and 4 decreasing in length ; rostrum with the apical third pilose, 
joint 3 much shorter than 1. Pronotum hexagonal, deeply sulcate down the middle anteriorly; the 
anterior lobe almost smooth, with two prominent, smooth, rounded tubercles on the disc and one on each 
side posteriorly ; the anterior angles dentiform, oblique, strongly produced; the posterior lobe rugose, 
with two anteriorly converging carine on the disc, these becoming evanescent behind and extending on 
to the base of the anterior lobe in front; the hind angles rounded, raised, and moderately dilated. 
Scutellum transversely rugose, with two posteriorly coalescent carine on the disc, the apical process 
horizontal, stout, and rather short. Abdomen moderately dilated at the sides, rounded at the apex. 
Legs moderately long : anterior and intermediate femora each armed on the underside before the apex with 
two, transversely placed, short teeth ; posterior femora slightly swollen on the lower side before the apex. 
Length 25, breadth 8} millim. 
Hab. Panama, Bugaba (Champion). 
One specimen. This species has very much the facies of Conorrhinus venosus, Stal; 
but the head is much shorter, with the antenniferous processes short (the antenne, in 
consequence, being inserted much nearer the eyes), the post-ocular portion very little 
longer than the ocelli, and the eyes very large. It has a longer pronotum and a shorter 
scutellar process than the South-American L. gentculatus (Latr.) (=corticalis, Walk.). 
The red tubercles on the disc and sides of the anterior lobe of the pronotum resemble 
those of Spiniger rubropictus. 
Subfam. PIRATINA. 
The six known American genera of this subfamily of Reduviide are all represented 
within our limits, and nearly all the Central-American species belong to known 
Tropical South-American forms, one only being treated as new.
