EURHEXIUS.—JUBUS. 43 
terminal joint scarcely so long as the preceding two together; the club very loosely 
articulated. Head broad and remarkably short, so as to be very strongly transverse ; 
the clypeal margin elevated, a linear curved impression behind it; the vertex behind 
distinctly impressed in the middle. Thorax much constricted at the side behind the 
middle, with a very deep median channel, and a transverse sulcus before the base con- 
necting three impressions. Elytra with the sutural stria foveolate at the base, a second 
fovea near this, and external to this latter a broader depression. 
This insect also is unique; the individual being probably a male, as the apex of the 
hind body is curvate and the extremity concave. The elongate first dorsal plate of the 
hind body renders the species very distinct. 
4. Kurhexius trimiodes. 
Minor, angustulus, subtiliter pubescens, nitidus ; antennis tenuibus, clava tri-articulata ; capite minore, ante- 
rius impresso, utrinque foveolato; prothorace elongato, canaliculato, ante basin transversim sulcato; 
elytris basi sex-foveolata. 
Long. 13 millim. 
Hab. GUATEMALA, Totonicapam 8500 to 10,500 (Champion). 
This is very distinct from the other species on account of its narrower form and 
slender antenne ; these latter have the basal joint not elongate, but little longer than 
the second, the second joint bead-like and considerably larger than the following one, 
the joints 3-8 small, similar to one another, the ninth and tenth markedly larger, trans- 
verse, the terminal joint rather elongate. ‘The head is short, but almost triangular 
in form, the vertex impressed in the middle behind. The thorax is elongate, much 
narrowed behind, the greatest width rather in front of the middle. The elytra have 
three impressions on each at the base, the median impression extending backwards as a 
short fold. The first dorsal segment of the hind body is scarcely longer than the second. 
Only two examples were met with; they are no doubt male and female, the penulti- 
mate ventral ring being much abbreviated in the middle in the specimen I take to be 
the former sex. 
_JUBUS. 
Jubus, Schaufuss, Nunq. Otios. ii. p. 454 (1876) ; Reitter, Verh. Ver. Briinn, xx. pp. 199 & 211 
(1882). 
Schaufuss includes in this genus three species from Colombia, in addition to the one 
from Mexico which is apparently the type. This author assigns two unequal claws to 
Jubus, but Reitter surmises it may prove to have two equal claws; I follow the latter 
in the position I give the genus.
