338 RHYNCHOPHORA. 
9. Chryasus plagiatus, sp.n. (Tab. XVII. figg. 21, 21a, 4, ¢.) 
Rhomboid-ovate, narrow, flattened above, opaque, black, the elytra each with a broad rufo-testaceous stripe 
on the outer part of the disc extending to near the apex, the antenne and tarsi ferruginous, the abdomen 
rufous; glabrous above, subglabrous and slightly shining beneath. Head very finely punctate ; rostrum 
stout, curved, about as long as the head and prothorax, striato-punctate to the tip, the antenne inserted 
at the middle, the antennal club ovate. Prothorax broader than long, subconical, feebly constricted in 
front; densely, obliquely strigose, the narrow depressed spaces very finely, confluently punctate. Elytra 
narrowing from about the basal third, the obliquely truncated humeri in a line with the sides of the 
prothorax; deeply punctato-sulcate, the interstices dull and convex throughout. Beneath closely, the 
abdomen more sparsely, punctate. Prosternum subtriangularly depressed down the middle, the 
depression not extending beyond the subapical groove. Legs rather elongate; femora sublinear, each 
armed beyond the middle with a small acute tooth, the intermediate and posterior pairs also with several 
minute denticles nearer the base. 
Length 22, breadth 14 millim. (¢?) 
Hab. Panama, Bugaba (Champion). 
One specimen only of this peculiar little insect has been obtained. The longi- 
tudinally strigose prothorax, the convex elytral interstices, the less prominent humeri, 
the longer femora, the straighter tibie, &c., distinguish it from C. cavernosus. 
DEIPYRUS, gen. nov. 
Rostrum very stout, arcuate, moderately long, and separated from the globose head by a deep transverse groove ; 
mandibles short, decussate; antenne with an ovate club, the outer joints of the funiculus transverse ; 
prothorax feebly constricted in front; scutellum small, flat, subtriangular; elytra a little wider than the 
prothorax, with the humeri oblique and not prominent; pygidium not visible ; prosternum unarmed, 
with a deep transverse excavation near the apex, limited on each side by a short oblique ridge ; anterior 
coxe separated by rather less than their own width; femora unarmed; tarsal claws long, divergent ; 
body oblong-elliptic, coarsely sculptured, setose. 
Type, D. hirsutulus. 
The single species from which the above characters are taken is one of the numerous 
isolated Tropical-American forms that seems to require a distinctive generic name. 
It approaches Chryasus, Centrinites, and Limnobaris (as extended by Casey), and the 
vestiture is like that of Chetobaris. 
1. Deipyrus hirsutulus, sp.n. (Tab. XVII. figg. 23, 23 @ *.) 
_ Rather narrow, shining, piceous or rufo-piceous; the upper surface and legs somewhat thickly clothed with 
long, suberect, fulvous sete, the under surface with scattered decumbent hairs. Head finely alutaceous, 
deeply transversely sulcate between the eyes; rostrum about as long as the head and prothorax, 
thickly punctate, the antenne inserted at the middle. Prothorax transverse, narrowed and constricted 
in front; coarsely, confluently punctate, and sometimes with an indication of a short median carina. 
Elytra punctato-sulcate, the interstices about as wide as the strive, becoming a little broader and flatter 
towards the suture, each with a scattered row of rather coarse punctures. Beneath coarsely, sparsely 
punctate. Legs short; tibie feebly unguiculate. 
Length 24-23, breadth 1-14 millim. 
Hab. Panama, Bugaba (Champion). 
* The insect is narrower than represented on the Plate.
