710 RHYNCHOPHORA. 
set with rather coarse, short, erect sete, the legs setose. Head densely punctate, the eyes small, laterally 
placed; rostrum very short, stout, curved, a little widened at the base and apex, squamose and rugulose 
at the base, the apical half bare and finely punctate, the antenne inserted at a little behind the middle, 
the club ovate. Prothorax rather convex, transverse, subtruncate at the base, rounded at the sides, 
narrowed and feebly constricted in front ; densely punctate. Scutellum not visible. Elytra considerably 
wider than the prothorax, truncate at the base, subparallel in their basal half ; finely punctate-striate, 
the alternate interstices convex. Beneath dull, densely, finely punctate. Mesosternum prominent, 
v-shaped. Legs short; anterior femora unarmed, the other with a short tooth ; tibie almost straight on 
their outer edge. 
Length 3, breadth 13 millim. (9 ?) 
Hab. Panama, near the city (Champion). 
One specimen. The subcylindrical shape, the truncate base of the prothorax and of 
the elytra, the unarmed anterior femora, &c., distinguish this small species. ‘The 
prothorax has a whitish spot in the middle at the base, and a dark patch on each 
side of it. | 
ULOSOMUS. 
Ulosomus, Schénherr, Cure. Disp. Meth. p. 293 (1826); Gen. Cure. iv. p. 316; Lacordaire, Gen. 
Col. vii. p. 100. 
The few described species of this genus are all Antillean. The four now added from 
our region agree in the following characters :— 
Funiculus 6-jointed; eyes distant; rostrum very short and broad, almost straight, at most feebly curved, 
rugose to the tip in the ¢, the antenn@ inserted at the middle; scutellum visible; metathoracic 
_ episterna exposed; ventral segment 2 very little longer than 3; femora unidentate or unarmed; meso- 
sternum very prominent, feebly arcuate-emarginate in front ; body squamose and strongly setose. 
Type, U. ertnaceus, Boh. 
The differences between Ulosomus and Ulosominus have already been pointed out, 
anted, p. 483. 
§ 1. Femora unidentate. 
1. Ulosomus horribilis, sp. n. (Tab. XXXV. figg. 8, 8a, 0.) 
Oblong-ovate, piceous, the antennz ferruginous ; densely clothed with pale brownish scales and also thickly 
set with very long, coarse, erect sete, which are clustered into large fascicles on the prominences of the 
upper surface—six on the prothorax and various others on the disc of the elytra, the latter broadly 
infuscate across the middle and with a transverse series of blackish spots at the base, the legs fusco- 
annulate and strongly setose, the scutellum ochreous. Head densely punctate, the eyes distant; rostrum 
short, flattened, almost straight, rugulosely punctate. Prothorax transverse, abruptly narrowed and 
strongly constricted in front, subtruncate at the base; densely, finely punctate, with four prominences 
extending across the middle and two others at the apex, the disc depressed along the centre. Elytra 
considerably wider than the prothorax, subparallel to about the middle, the humeri prominent, obliquely 
truncated in front; irregularly seriate-punctate, the alternate interstices with scattered setigerous 
prominences, those on 2 and 4 large. Beneath closely punctate. Legs rather long; femora unidentate. 
Length 41, breadth 2 millim. (¢ ?) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. A very remarkable insect, recognizable by the large fascicles of long, 
coarse sete arising from the dorsal prominences of the prothorax and elytra.
