72 RHYNCHOPHORA. 
narrow and a little convex. Legs rather long, yellow, but varied with fuscous, the 
middle of the femora, the knees, and the tibie before the extremity being of this 
colour. Middle coxe slightly separated. Under surface without any distinct pubes- 
cence; cox and trochanters black. 
The variegate colour of the legs will be one of the best clues to the identification of 
this obscure insect. Only three examples have been received; the one from Northern 
Sonora does not differ in any important particular, so far as I can discover, from the 
two found on the Volcan de Chiriqui. Perhaps all are of the male sex. 
56. Apion epicum, sp. n. 
Minus elongatum, nigrum, subnitidum, fere nudum, pedibus rufo-testaceis, antennarum basi flavescente, apice 
fusco; rostro subgracili, mediocri, parum sculpturato ; prothorace fere brevi, parce punctato : elytris sat 
profunde sulcatis, interstitiis planis. 
Long. 2 millim. 
Hab. Panama, Pefia Blanca (Champion). 
Rostrum slender, cylindrical, shining, in the male about as long as the head and 
thorax, in the female slightly longer; eyes convex, not widely separated, the space 
between them obsoletely grooved; antenne inserted a little farther in front of the 
eyes than the width of the interocular space. ‘Thorax coarsely but not closely 
punctured. Elytra broad and short, with moderately deep grooves and broad flat 
interstices. Legs clear yellow; coxe and trochanters reddish. Under surface bare ; 
middle coxe rather widely separated. Seven specimens. 
This is another obscure species, but differing from nearly all the Central-American 
allied forms with similarly-coloured legs by the more slender rostrum and the absence 
of pubescence on the under surface. | 
57. Apion errabundum, sp. n. 
Angustum, nigrum, opacum, antennarum basi pedibusque rufis, femoribus intermediis et posterioribus nigri- 
cantibus; rostro mediocri, gracili; prothorace brevi, fortiter punctato; elytris minus profunde sulcatis, 
sulcis fortiter punctatis, interstitiis planis. 
Long. 14 millim. 
Hab. Mexico, Chilpancingo in June and July (7. H. Smith). 
Rostrum slender, cylindrical, curved, nearly as long as the head and thorax, shining, 
except at the base; eyes convex, the space between them rather small, obscurely 
bisulcate ; antennee inserted quite as far in front of the eyes as the width of the ocular 
interval. Thorax transverse, narrowed in front, rounded at the sides, rather coarsely 
punctate, with a very feeble white setosity, the channel in front of the base in the 
middle scarcely visible. Elytra dull, black, with conspicuous but shallow grooves, the 
punctures in which are very evident; the interstices flat and rather broad. Legs 
reddish, the middle and hind femora black. Middle coxe distinctly separated. Two 
specimens.
