62 RHYNCHOPHORA. 
transverse, sinuous fascia below the base, and a few small scattered spots, black; the vestiture of the 
under surface coarser, ochreous, the ventral segments 3-5 almost bare, that of the legs fulvous and 
cinereous intermixed. Eyes moderately large, narrowly separated. Rostrum carinate and rugulose at 
the base. Joint 2 of the funiculus elongate, nearly as long as 3-9 united. Prothorax much broader 
than long, narrowing from the base, strongly constricted in front; densely, rugulosely punctate, and also 
carinate, the disc somewhat swollen. Elytra narrowing from a little below the base, blunt at the apex, 
the apices distinctly explanate; rather coarsely seriate-punctate, the punctures distant one from another, 
the interstices 5, 7, and 9 sharply, and 3 more feebly, costate, the ridges on 7 and 9 merging into 
the humeral callus. Meso- and metasternum broad and flattened between the intermediate coxee. Legs 
rather short; femora unidentate beneath, the posterior pair carinate externally and not reaching the 
apex of the abdomen ; the area on the anterior pair coarsely strigose; tibic almost straight. 
Length 6, breadth 3, millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen. The cinereo-variegate, nigro-fasciate elytra, with sharply costate 
alternate interstices and narrowly explanate apices, separate C. octocostatus from its 
allies. It approaches the genus Copturosomus. 
4, Copturomimus stridulans, sp. n. (Tab. IV. figg. 21; 21a, ant. femur.) 
Subovate, short, robust, nigro-piceous, the antenne and the tips of the tarsi ferruginous; sparsely clothed 
with small, narrow, ochreous and cinereous scales, which are condensed into three interrupted vitte on 
the prothorax and various scattered. irregular, more or less confluent patches on the elytra (a small spot 
near the apex of the eighth interstice usually conspicuous), the rest of the elytral surface with small 
blackish or fuscous scales, these latter condensed into a common subquadrate patch before the middle of 
the suture and a ~-shaped mark towards the apex; the vestiture of the under surface and legs sparse, 
cinereous. Head sparsely, minutely punctate, the vertex without a smoother space in the middle; eyes 
very large, narrowly separated; rostrum stout, carinate and rugulose at the base; joint 2 of the 
funiculus elongate, longer than 3 and 4 united. Prothorax short, narrowing from near the base; 
densely, rugosely punctate and feebly carinate. Elytra rounded-subquadrate, blunt at the apex; deeply 
striate, the striw finely punctate, the interstices flat and rugose. Meso- and metasternum flattened and 
unimpressed between the intermediate coxw. Legs short, stout; femora feebly unidentate beneath, the 
posterior pair carinate externally, the area on the anterior pair large, depressed, and somewhat coarsely 
strigose ; tibie almost straight. 
Length 34-43, breadth 2-25 millim. 
Hab. Panama, Bugaba (Champion). 
Eleven specimens. Near C. cinereus, but with a shorter, rugosely punctate 
prothorax, subtruncate elytra, which have a subquadrate blackish patch near the 
middle of the suture, a larger strigose area on the anterior femora, and an unimpressed 
mesosternum. 
5. Copturomimus ceruleotinctus, sp. n. (Tab. IV. figg. 22, 22 a, b, ¢.) 
Subovate, piceous or rufo-piceous, the prothorax black, rufescent at the sides or apex, the elytra each with 
a large, outwardly narrowed, subtriangular patch on the basal half of the disc (sometimes reaching the 
suture), a large patch before the apex, and a spot on the humeral callus, black, the rostrum, antenne, 
and legs testaceous; the prothorax sparsely clothed with narrow ochreous scales, and sometimes with a 
white median line in front, the posterior lobe with a metallic blue or green reflection; the elytra mottled 
with fine, narrow, ochreous and whitish scales, and sometimes with a denser white patch at the sides
