HYLOCURUS. 223 
This species is not in our collection, but I have seen a typical specimen from that of 
Chapuis. It is a male, the female (and therefore the sexual differences) being unknown 
to Hichhoff. Closely resembling H. cancellatus, 3, in general appearance, it is very 
much smaller, piceous-brown, and not blackish, and has the basal half of the prothorax 
punctate rather than granulate; the elytra are relatively shorter, the interstices less 
broken towards the declivity, round which they terminate in a series of short blunt 
teeth; the declivity is more abruptly truncate, nearly vertical, covered with scattered 
upstanding scales, somewhat irregularly punctured, with two tubercles only in the line 
of the third interstice. Length 1:6 millim. 
The following species are all based on examples taken from the débris of tobacco- 
bales unpacked in Paris, and have been forwarded to me by M. Grouvelle. Their 
origin is probably Mexican, but it is doubtful in the case of one or two examples, 
which may be natives of San Domingo or Brazil. ‘The types are in my collection. 
Hylocurus retusipennis, sp. n. 
Mas. Breviter cylindricus, subnitidus, niger, antennis pedibusque fusco-testaceis ; prothorace postice punctato ; 
elytris illo haud sesquilongioribus, postice dilatatis, striatis, striis grosse punctatis, interstitiis posterius 
carinatis et in dentes obtusos productis; declivitate circulatim retusa, glabra, in limbo superiore striato- 
punctata, punctis infra obsolescentibus, interstitio 3° trituberculato. 
Long. 2 millim. 
Male. Cylindric, short, moderately shining, black, the antennz and legs brown-testaceous. Prothorax broadly . 
rounded at the apex, without prominent tubercles, the dorsal elevation indistinct, rufescent, the surface 
slightly impressed behind it, subnitid and moderately closely punctured at the base. Elytra less than 
one-half longer than the prothorax, evidently widened towards the apex, the inferior margin of which is 
transverse rather than oblique, with a small excision on each side, and the sutural angle produced into a 
rather broad triangular mucro; surface strongly punctate-striate, the stris deeper behind, the interstices 
shining, irregular, convex, carinate before the declivity and ending round its margin in a series of short 
obtuse teeth, bearing scattered squamiform hairs; retuse area vertical, circular, subopaque, glabrous, 
striato-punctate above, with the interstices elevated, obsoletely punctured below, without elevated interstices, 
the margins of the suture elevated and tuberculate throughout, the third interstice with three pointed 
tubercles. Underside black, the abdomen rather closely punctured. 
Hab. t Mexico. 
I have one specimen frem Mexican tobacco. The species is of the configuration of 
H. elegans, but larger, with the apical retuse surface glabrous and not squamous, duller 
and trituberculate on either side. In the latter point it approaches ZH. discifer, Eichh., 
but differs in having the elytra very markedly dilated towards the apex. 
Hylocurus alienus. 
9. Hylocurus alienus, Kichh. Rat. Tom. p. 301°. 
Mas. Cylindricus, nigro-piceus ; prothorace latitudine longiore, ad basin granulato-punctato ; elytris parallelis, 
punctato-striatis, punctis sat magnis dilatatis, interstitiis angustis, convexis, in tuberculos obtusos 
terminatis ; retusione circulari, subobliqua, convexa, subopaca, in limbo superiore striato-punctata, sutura 
subelevata subtiliter tuberculata, lateribus muticis. 
Long. 2 millim.
