GLOCHINOCERUS. 267 
thorace latitudine longiore, postice levi, subopaco; elytris subtiliter punctatis, ad apicem subretusis. 
retusione ad latera et infra marginata, subopaca, glabra, utrinque juxta suturam linea tuberculata 
ornata. 
Long. 3-6-4 millim. 
Mas. Fronte subdeplanata, haud cirrata; prothoracis apice bituberculato. 
Fem. Fronte concava, pilis fulvis cirratis in fasciculos ordinatis compta. 
Oblong, cylindrical, subglabrous, dull brown with a testaceous tinge, the head, dise of prothorax, and sides and 
apex of the elytra darker. Front (¢) somewhat flat, punctured, thinly pubescent, with a median supra- 
oral raised line ; front ( @ ) deeply excised, its margins with four brushes of fulvous hairs curled inwards, 
one rising from each side of the upper border and one above each mandible; the latter strong, black, 
larger in the female; eyes oval, emarginate ; antennez testaceous-brown, the scape more flattened and 
the club longer in the female. Prothorax longer than broad, widest behind the middle, the sides scarcely 
rounded, the apex circularly rounded, and in the male bituberculate, the hind angles subrectangular, the 
hind margin sub-bisinuate ; surface with a median transverse elevated line, in front asperate, more strongly 
in the male, behind opaque, impunctate. Scutellum rather large, rounded-triangular. Hlytra as wide as 
the prothorax and less than one-half longer, with subtruncate base, obliquely rounded shoulders, and sub- 
parallel sides, strongly inflexed behind, the apical margin therefore obtuse ; surface cylindrical, with very 
fine and rather close punctuation in indistinct rows; apex subretuse, nearly vertical, with a defined 
circular margin at the sides and beneath, but obsolete above, its surface opaque, glabrous, impunctate, 
impressed above along the suture, on each side with a raised tuberculate line, beginning at the upper 
extremity of the marginal border, then running parallel to the sulcus, below incurved and less distinct. 
Underside and legs testaceous, the tibie: more distinctly spined in the male. 
Hab. Guatemaua, Cerro Zunil (Champion). 
‘wo pairs were obtained. As this species is like the next, of which the colour is 
darker, it is probable that these examples have not reached maturity. The sexes have 
been determined by dissection, and the result agrees with the observations of Hopkins 
on the sexual characters of Corthylus and Pterocyclon. 
2. Glochinocerus gemellus, sp. n. 
Fem. Oblonga, cylindrica, subnitida, nigro-fusca, antennis pedibusque fusco-testaceis ; G. retusipennt assimilis, 
pilorum fasciculis inferis in fronte densioribus, elytris proportione longioribus, declivitate in singulo 
elytro gibbosa, sine ordine tuberculata, linea elevata nulla, distinguenda. 
Long. 3°8-4 millim, 
Female. Very like the female of G. retusipennis. Oblong, cylindrical, blackish-fuscous, with the legs and 
antenne testaceous, and the frontal fringe bright red-brown; o wholly black, with the legs, antenna, 
and fringe infuscate. Head with the insertion of the antenne less near the mouth, and the brush of 
hairs arising above it wider and denser. Prothorax with the discal transverse line less noticeable. 
Elytra relatively a little longer, more accurately parallel-sided, the suture impressed before the declivity, 
the surface more evidently punctured; apical surface more rounded above, with the side-margin not 
traceable above the middle, opaque, impressed along the suture to the middle, laterally convex, and with 
scattered minute piliferous tubercles, the elevated line absent. 
Hab. Guatemaua, Quiché Mountains, Volcan de Agua (Champion). 
A single example was taken at each locality. That from the Quiché Mountains is 
the darker, and has the antennal club entirely black, whereas it is testaceous in the 
other. ‘The difference of colour, especially noticeable in the frontal fringe, is not 
accompanied by any difference in structure.
