Found in abundance at Cerro Zunil and also in Chiriqui, some of the specimens 
agreeing well with a co-type from Venezuela sent me by Dr. Heller. A species of 
large size (varying from 62-8 millim. in length), piceous or rufo-piceous in colour, 
with a broad, anteriorly attenuate vitta on each side of the prothorax, a transverse 
patch at the shoulder and an oblong mark at the apex of each elytron, and a trans- 
verse patch on the prosternum, densely clothed with ochreous or whitish scales. 
The femora have a minute tooth exterior to the larger one, which is very sharp 
on the posterior pair; they are annulate with whitish or ochreous a little beyond 
the middle, and on the anterior pair above there is a dense line of fulvous scales 
extending along their basal half. The tarsal claws have a short tooth. The male has 
a stouter and more arched rostrum than the female. ‘The sculpture of the elytra is 
rather variable. C. inexplicatus is a close ally of C. amabdilis, Boh., from Cayenne, the 
latter having a large oblong patch at the base of each elytron. 
34. Conotrachelus quadripustulatus, sp.n. (Tab. XVIII. figg. 29, 29a, 3.) 
Subovate, shining, piceous or rufo-piceous ; the vestiture sparse, ochreous or whitish, here and there subfasci- 
culate on the elytra, the prothorax with a sinuous line on each side of the disc, the elytra with an 
interrupted transverse patch at the shoulder and a small spot on the subapical callus, and the prosternum 
with a transverse space in front of the anterior coxe, densely clothed with ochreous scales; the femora 
with a ring of whitish scales a little beyond the middle, the anterior pair with at most a faint line of 
fulvous scales at the base above. Head densely, rugosely punctate; rostrum exceedingly stout, strongly 
curved, considerably longer than the head and prothorax, tapering outwardly, 5-carinate to beyond 
the middle and sparsely punctate thence to the apex, the antennx inserted at about one-third from the 
tip, Joints 1 and 2 of the funiculus subequal in length. Prothorax transverse, rounded at the sides 
anteriorly, parallel behind, feebly constricted in front, and strongly bisinuate at the base; the entire 
surface very coarsely, confluently punctate. Elytra subtriangular, rounded at the sides posteriorly ; 
coarsely and deeply seriate-punctate, the interstices 3, 5,7, and 9 costate, the ridge on 3 and 5 prominent, 
broadly and abruptly twice interrupted, that on 7 entire. Mesosternum flattened between the coxe, 
obsoletely bituberculate in front. Ventral segments very sparsely, finely punctate. Femora clavate, 
each with an acute triangular tooth and at most the faintest indication of a minute prominence exterior 
to it. Tarsal claws with a short tooth. 
Length 43-54, breadth 23-23 millim. (¢.) 
Hab. GuareMaua, Senahu in Vera Paz (Champion); Panama, Bugaba (Champion). 
Seven specimens, probably all males. Separable from C. qguadrinotatus by the much 
stouter rostrum of the male, the very rugose prothorax, and the shorter tooth of the
