112 RHYNCHOPHORA. 
Sallé’s collection were, however, labelled E. depilis, Schonh., which I consider to be 
the male sex, in a worn condition, of E. cultripennis. An example of EF. cultripennis 
sent from Chevrolat’s collection by Dr. Aurivillius is a female of this species. 
E. cultripennis has the thorax obscurely punctate, and, in addition, more or less 
coarsely and abundantly transversely rugose-sulcate. ‘The insect is unusually elongate 
in proportion to its width, and the thorax is remarkably long; viewed in profile, the 
angle at the junction of the dorsal and apical parts of the wing-cases is much less 
broadly rounded than usual, the apical part being perpendicular; the sexual disparity 
is very marked, the female being usually quite twice the size of the male, the outline 
of the body in the latter sex being so slender and parallel as to remind one of the 
genus Lirus. 
We figure the species in profile so as to allow an idea to be formed of the 
sexual distinctions in the shape. Such distinctions exist in many other species of the 
genus, though usually to a less extent than in H. cultripennis; indeed they vary not 
only from species to species, but also in the same species to a certain extent; the 
variation apparently being due to the fact that some males partake to a greater or less 
extent of the peculiar sexual outlines of the female. 
Boheman’s description of E. depilis no doubt refers to worn examples of the male of 
E. cultripennis, and a specimen sent from Schonherr’s collection—not, however, the 
type—as L. depilis is certainly E. cultripennis, 3 . 
16. Epicerus inflatus, sp.n. (Tab. V. fig. 5.) 
Anguste ovalis, convexus, niger, nitidus, fortius punctatus, fere esquamosus. 
Long. 103 millim. 
Hab. Mexico, Yolotepec (Sal/é). 
Rostrum rather short and broad, moderately deeply impressed on the middle, 
without fovea on the forehead. Thorax narrowed in front, not elongate, not con- 
stricted behind, with coarse rugulose sculpture and a very feeble depression along the 
middle, the fine basal margin unusually distinct and definite. LElytra not elongate, 
convex, rounded at the sides, with the surface uneven and with series of rather large 
punctures ; there is a slight squamosity on the depressed spots. ‘Two specimens. 
The bare surface is not, I believe, due to abrasion, the two specimens being in very 
good preservation. They represent, I think, the sexes, the female having the elytra 
rather more convex. 
17. Epicerus frontere, sp.n. (Tab. V. fig. 6.) 
Pyriformis, convexus, niger, fusco-setosus; prothorace fortiter punctato, transversim subcylindrico ; elytris 
regulariter seriatim punctatis. 
Long. 13 millim. 
Hab. Mexico, Frontera in Tabasco (Héoge, H. H. Smith).
