38 RHYNCHOPHORA. 
men known has the middle tibie acuminate at the apex internally, and is probably a 
male. 
A very peculiar insect whose genus is somewhat doubtful, but at present it cannot be 
placed elsewhere than in Hugnamptus. 
22, Kugnamptus nigripennis, sp. n. (Tab. II. fig. 10.) 
Rufus, griseo-setosus ; antennis valde elongatis elytrisque nigris, his seriatim fortiter denseque punctatis, inter- 
stitiis perangustis. 
Long. cum rostro 5; millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Rostrum somewhat longer than usual. Head short, the constriction of the neck 
being near to the eyes, these large, widely separated, the space between them very ~ 
sparingly punctate. Antenne quite black, with extremely long club, the joints of which 
are linear, the terminal joint only about half as long as the tenth. Thorax coarsely, 
rather deeply, and closely punctate. Elytra black, the lateral margin red, bearing a 
long griseous setosity; the punctuation deep, coarse, and very close, but not perfectly 
regular as in L. brevicollis, the interstices very narrow and rendered somewhat indefinite 
by the interstitial punctures being only imperfectly separated from the coarse serial 
sculpture. Legs red, with the tips of the femora a little infuscate. 
I do not detect any sexual distinction among the four specimens from which I 
describe this species ; they are probably all of the female sex. 
23, Eugnamptus suturalis, sp. n. 
Rufus, griseo-setosus ; antennis, pedibus ex parte majore elytrisque nigris, his vitta suturali anterius latiore 
rufa, densius, fortius profundiusque seriatim punctatis. 
Long. cum rostro 5 millim. 
Hab. Panama, Volcan de Chiriqui, Boquete, Caldera (Champion). 
Closely allied to E. nigripennis, but with the club of the antenne rather less elongate ; 
the elytra with the sculpture rather less deep and rugulose, especially on the apical 
portion, and the suture, as well as the outer margin, red; the tibie and tarsi quite 
black, the femora black at the extremities, the black colour extending nearer to 
the base on the upper than it does on the lower aspect. Four examples. 
Our collections also contain an example of another species from Bugaba allied to 
this and to E. nigripennis, but it is in too decayed a condition to describe from. 
24. Kugnamptus plebeius. 
Angustus, nigerrimus, pube grisea erecta vestitus, fortiter punctatus. 
Long. cum rostro 43 millim. 
Hab. Mexico, Amula 6000 feet, and Chilpancingo in Guerrero 4000 feet (H. H. 
Smith, June 1888). 
Club of the antenne moderately long, its three joints subequal in length. Rostrum
