Hab. Panama, Bugaba (Champion). 
One specimen. Very like C. quadrilineatus (infra), but with the elytra relatively 
narrower, the vestiture much sparser (except at the base), the humeri less prominent, 
the seriate punctures coarser, the elevations on the third interstice smaller and less 
swollen, the mesosternum less protuberant in front, &c. 
65. Conotrachelus albolineatus, sp. n. (Tab. XIX. figg. 13,134, 3.) 
Subovate, dull, black, the antenne and tarsi obscure ferruginous, and the elytra and tibiee mottled with the 
same colour; the vestiture very fine, brownish-ochreous, intermixed with whitish, dense on the rostrum, 
prothorax, and base of the elytra and sparser elsewhere, the prothorax with two rather broad whitish 
vittee on the disc and a whitish line on each side, these being continued on to the extreme base of the 
elytra, the latter with a cluster of dense ochreous spots on each side at the apex, the femora biannulate 
with whitish. Head densely punctate ; rostrum very stout, arcuate, as long as the head and prothorax, 
rugulose and finely unicarinate, thickly punctate and bare at the tip, the antenne inserted near the apex, 
joint 2 of the funiculus shorter than 1. Prothorax broader than long, narrowed and compressed in front, 
moderately sinuate at the base; densely, finely punctate, carinate almost to the base, the disc with two 
minute granules about the middle. Elytra subtriangular, compressed beneath the humeri, which are 
obliquely truncated in front; seriate-punctate, the punctures oblong in shape, the interstices dull and 
rugulose, 3, 5, 7, and 9 very sharply costate, the ridge on both 3 and 5 abruptly twice interrupted and 
the elevations very prominent. Mesosternum flattened between the cox. Ventral segments sparsely, 
finely punctate. Femora unidentate. ‘arsal claws with a short tooth, 
Length 3-34, breadth 13-13 millim. (<¢-) 
Hab. Panama, David in Chiriqui (Champion). 
Two specimens from Chiriqui, precisely similar. Smaller than C. guadrilineatus and 
C. venustus, the dorsal vitte of the prothorax broader. The elytra are narrower 
than in the first-named species, with the dorsal prominences much smaller, and the 
ochreous apical spots are lateral. Compared with C. venustus, the elytra are duller, with 
the vestiture closer (the densely clothed basal portion being also more extended), and 
the seriate punctures not nearly so coarse. 
C. quadriguttatus, Kirsch, from Peru, is a closely allied form, but has much less 
prominent dorsal elevations on the elytra. 
66. Conotrachelus eburneus, sp. n. (Tab. XIX. figg. 14, 144, 2.) 
Conotrachelus ventralis, Jekel, in litt. (nec Lec.). 
Subovate, nigro-piceous, the antenne, and the tibie and tarsi in part, ferruginous; the vestiture fine, dense, 
white, the elytra with the apical fifth fulvous variegated with white, preceded by a denser broad white 
fascia, the suture and third interstice fulvous at the middle, the prothorax with a similarly-coloured 
subtriangular patch on the disc behind, divided down the centre by a white line, the head, rostrum, and 
legs fulvous, the femora biannulate with white, the under surface fulvous and white, the abdomen almost 
bare. Head densely punctate, depressed between the eyes; rostrum very stout, curved, about as long as 
the head and prothorax, rugulosely punctate throughout, and also tricarinate, the antennz inserted 
towards the tip, joint 2 of the funiculus much shorter than 1. Prothorax convex, transversely sub-
