THYSANOCNEMIS. 205 
3. Thysanocnemis bicinctus, sp. n. (Tab. XI. figg. 28, 284, 3.) 
Oblong-ovate, black, the rostrum in part, the head, prothorax, and elytra obscure ferruginous, the prothorax 
with two short vittee on the disc behind and the sides black, the elytra with two broad, clearly defined, 
transverse black fasciee, both widening outwards—one median and the other before the apex, the two 
separated by a narrow, feebly sinuate band of the ground-colour, the antenne and legs ferruginous, the 
femora blackish at the middle; thickly pubescent, the pubescence ochreous on the reddish portions cf 
the surface and darker elsewhere, the elytra also with widely scattered, short, pallid, semierect, squamiform 
sete. Head rugulosely punctate, the eyes very narrowly separated ; rostrum stout, curved, a little longer 
than the prothorax, smooth and carinate down the centre, rugulosely punctate and faintly carinate at the 
sides, the antenne inserted at about one-third from the tip. Prothorax strongly transverse, rounded at 
the sides, much narrowed in front, densely punctate. Elytra subparallel in their basal third ; finely 
punctate-striate, the interstices equal in width, almost flat, and densely punctulate. Femora unarmed ; 
anterior tibie simply sinuate. 
Length 24, breadth 13 millim. (<¢.) 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
One specimen. A near ally of ZT. odscurus, but more oblong in shape, the eyes 
almost contiguous above, the elytra with two broad, clearly-defined, transverse, black 
fasciee separated by a narrow ferruginous band. 
4, Thysanocnemis suturalis, sp.n. (Tab. XI. figg. 29, 29 a.) 
Subovate, rufo-piceous, darker beneath, the antenne and legs ferruginous, the femora blackish in the middle ; 
clothed with fine yellowish-grey pubescence, that on the first elytral interstice velvety-black from a little 
below the base to the apex and that on the scutellum whitish, the elytra also with short, scattered, 
whitish, squamiform sete, which tend to form a common, transverse, irregular, postmedian fascia (the 
black sutural stripe being interrupted in a line with this by a patch of pallid pubescence), and extend 
down the second interstice thence to the tip. Head rugulosely punctate, the eyes narrowly separated ; 
rostrum stout, curved, about as long as the prothorax, widened in its apical third, carinate down the 
middle, the carina widening forwards, sulcate and rugulose at the sides, the antenne inserted towards 
the tip. Prothorax transverse, rounded at the sides, a little more narrowed in front than at the base, 
densely punctate. Elytra punctate-striate, the interstices convex and densely, rugulosely punctulate. 
Intermediate and hind femora obsoletely toothed ; anterior tibiw sinuate. 
Length 2,1,-22, breadth 1,,-1} millim. (¢ 2.) 
Hab. Guatemaa, Aceituno (Champion). 
Two specimens, no doubt male and female, one of them having the rostrum smoother 
than the other. Distinguishable by the interrupted velvety-black sutural stripe of the 
elytra, this being bordered on each side posteriorly by a row of the pallid squamiform 
setee which are scattered over the surface. 
5. Thysanocnemis ornatus, sp.n. (Tab. XI. figg. 30, 30a.) 
Subovate, rufo-piceous, the elytra with a common, interrupted, angulated, median fascia, widening outwards, 
and the apex broadly, the markings connected laterally, black, the antenne and legs ferruginous, the 
femora and tibie partly infuscate, the under surface in great part black ; clothed with fine pubescence, 
that on the light-coloured portions of the surface yellowish and that on the dark markings black, the 
scutellum, the base of the elytra on each side, and an oblong space on the suture a little beyond the 
middle, with whitish pubescence, the elytra also with widely scattered, short, whitish, squamiform seta. 
Rostrum short and stout, curved, about as long as the prothorax, carinate down the middle, the carina
