256 RHYNCHOPHORA, 
CERPHERES, gen. nov. 
Rostrum arcuate, stout, not longer than the head and prothorax ; mandibles short, notched on the inner edge, 
decussate; antennal club ovate; prothorax subconical, feebly constricted in front ; scutellum small, free, 
subquadrate; elytra wider than the prothorax, deeply striate throughout, the humeri oblique and not 
prominent; pygidium not visible; prosternum unarmed, deeply sulcate, the sulcus extending backward 
between the anterior coxe and forward to the apex ; femora unarmed, linear or feebly clavate, narrowly 
or obsoletely sulcate beneath; tarsal claws small, free; body more or less ovate, polished or finely 
alutaceous, glabrous above. 
Type, C. glabrescens. 
Two very small forms are referred to this genus, one (C. glabrescens) with the 
anterior cox narrowly separated and the femora linear, the other (C. rufescens) with 
the anterior coxe more distant and the femora subclavate *. Cerpheres is nearly related 
to Diorymerellus. 
1. Cerpheres glabrescens, sp. n. (Tab. XIV. fig. 12, ¢.) 
Subovate, narrow, shining black ; glabrous above, the scattered punctures on the legs and under surface each 
bearing a minute whitish scale. Head sparsely punctate, transversely depressed between the eyes ; 
rostrum curved, rather stout, a little longer than the prothorax, closely punctate, except along the median 
line, the antenne inserted at about the middle, the antennal club short ovate. Prothorax transverse, 
conical, feebly constricted in front; sparsely, rather coarsely punctate. Scutellum flat, subquadrate. 
Elytra considerably wider than the prothorax, narrowed from the middle, conjointly rounded at the apex, 
the humeri obtuse; sharply punctate-striate, the interstices broad, smooth, and flat. Beneath sparsely 
punctate ; first ventral segment deeply excavate down the middle. Prosternum with a deep subtriangular 
excavation extending backward between the anterior coxe, which are separated by about half their own 
width. Legs short and comparatively smooth ; femora linear, narrowly and shallowly sulcate beneath ; 
tibie almost straight. 
Length 22, breadth 14 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
One male. A small, glossy-black, almost glabrous form, with a narrow, conical 
prothorax and feebly sulcate femora, the prosternal sulcus extending narrowly back- 
ward between the anterior cox. Narrower and more shining than C. rufescens, wholly 
black, the prothorax rapidly narrowed from the base, the elytral interstices smoother, 
the anterior coxe much less widely separated. 
2. Cerpheres rufescens, sp. n. (Tab. XIV. fizg. 13, 13a, 3 .) 
Ovate, rather narrow, moderately shining, piceous or obscure castaneous, the elytra and legs ferruginous; 
glabrous above, subglabrous beneath. Head sparsely punctate, transversely grooved and obsoletely 
foveate between the eyes; rostrum arcuate, moderately stout, about as long as the prothorax, a little 
longer and smoother in the 9, the antenna inserted at the middle, joint 1 of the funiculus as long as 2-4 
united, the club ovate. Prothorax transverse, gradually narrowing from the base, constricted in front ; 
closely, somewhat coarsely punctate, except along a narrow median space. Scutellum oblong-subquadrate. 
Elytra narrowing from a little below the base, the humeri oblique and forming an almost continuous 
outline with the sides of the prothorax; deeply punctate-striate, the interstices flat, 2 and 3 or 2-4 with 
an irregular double, and the others wlth a single, row of very fine punctures. Beneath 
closely and 
rather coarsely, 
a broad space down the middle of the abdomen more sparsely and finely, punctate ; first 
* Baridius thoracicus, Kirsch, from Peru, approaches these forms ; but it has the prothorax obtusely margined 
at the sides anteriorly, and will doubtless have to form the type of a new genus,
