890 RHYNCHOPHORA. 
antennex inserted at the middle, joint 2 of the funiculus much shorter than 1. Prothorax transverse, 
narrowed and strongly constricted in front, deeply bisinuate at the base; densely, rugulosely punctate. 
Elytra subtriangular, compressed and a little dilated beneath the humeri, and narrowing thence to the 
apex, the humeri rounded and rather prominent; coarsely seriate-punctate, the interstices densely 
rugulose, 3, 5, 7, and 9 sharply costate, the ridge on 5 twice interrupted and that on 3 also interrupted 
beyond the middle. Mesosternum somewhat convex between the coxe, declivous and rather protuberant 
in front. Ventral segments finely, sparsely punctate. Femora clavate, sharply unidentate. Tarsal 
claws with a short tooth. 
Length 43, breadth 23 millim. (9 .) 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
One female. Extremely like C. miatus (2 ), but with a longer, slender, almost 
smooth, cylindrical rostrum, more widely separated eyes, an interrupted white ring on 
the head, a larger humeral patch on the elytra, and conspicuously triannulate femora ;. 
the mesosternum, too, is slightly convex in the centre in front. 
14. Conotrachelus squamulatus, sp.n. (Tab. XVIII. figg. 13, 134, 2.) 
Subovate, nigro-piceous, the legs and rostrum in part, and the antenna, ferruginous; densely clothed with 
reddish-brown, broad, oval scales, these becoming a little whiter along the basal margin of the elytra 
(the prothorax slightly mottled with whitish and brown, and the whitish scales showing a tendency to 
form a curved line on each side of the disc, in one specimen), the upper surface and legs also with 
scattered, fine, semierect, whitish sete, the femora faintly annulate. Head densely punctate; rostrum 
slender, curved, depressed at the base above, more than twice the length of the prothorax, shining, very 
sparsely punctate, striate towards the base, the antenne inserted just beyond the middle, joint 2 of the 
funiculus shorter than 1. Prothorax transverse, narrowed and constricted in front, parallel behind, 
the base bisinuate ; densely, finely punctate. Elytra subtriangular, with the humeri obliquely truncated 
in front and more or less dentiform; rather finely seriate-punctate, the interstices densely, minutely 
punctulate, 3, 5, 7, and 9 feebly costate, the ridge on 3 and 5 each reduced to three widely separated 
elevations, the short median one on 3 alone conspicuous. Mesosternum simply flattened between the 
coxe. Ventral segments sparsely, finely punctate. Femora clavate, unidentate. Tarsal claws with a 
short tooth. 
Length 34-4, breadth 2-23 millim. (2.) 
Hab. Mexico, Sierra (tde Agua) (ea coll. Flohr); Panama, Volcan de Chiriqui 
(Champion). 
Two females, agreeing inter se, except that the Mexican specimen has the prothorax 
rather mottled. This species somewhat resembles C. aristatus, but the clusters of 
coarse setee are wanting, the prothorax lacks the median prominence on the disc, the 
rostrum ( @ ) is slender, very elongate, and depressed at the base, the mesosternum is 
not depressed, &c. The vestiture of the upper surface is coarse, regular, squamiform, 
and almost unicolorous, and the sete are fine and whitish. 
15. Conotrachelus armatus, sp. n. 
Subovate, shining, nigro-piceous, the head, rostrum, antennw, elytra, and legs rufo-piceous or ferruginous, the 
intermediate and hind femora blackish in their basal half; above densely and uniformly clothed with 
brownish scales, those on the elytra oval and rather coarse, the others more elongate, and also with 
inconspicuous, short, scattered, decumbent, pallid hairs, the femora faintly annulate, the clothing of the 
under surface very sparse. Head closely, rugulosely punctate, depressed and foveate between the eyes ;
