66 HETEROMERA. 
setiferous impressions, the apices obtuse; beneath varying in colour from black to piceous-brown, smooth ; 
legs slender, rather long, black or brownish-piceous, the coxe, the basal half of the femora, and the four 
hinder tarsi in great part, testaceous, the femora smooth and glabrous. 
¢. Anterior femora armed with a short blunt tooth on the inner side beyond the middle; anterior tibie very 
slender and sinuous. 
Length 64-62 millim. ; breadth 13-1$ millim. (¢ 9.) 
Hab. Panama, Bugaba 1000 feet (Champion). 
Four examples, two of each sex. This insect has somewhat the facies. of certain 
species of Uroplatopsis, owing to the peculiar sculpture and colour of the elytra 
(resembling that of many Lycide and Hispide); but differs from them in the non- 
dilated intermediate joints of the antenne, differently-formed labial palpi, toothed 
anterior femora in the male, &c. 
COLPARTHRUM. 
Colparthrum, Kirsch, Berl. ent. Zeitschr. 1866, p. 204. 
Kirsch founded this genus upon a single species, C. gerstdckeri, Kirsch, from. 
Colombia, and gave as its chief diagnostics—(1) mandibles at the apex with three 
strong teeth of equal length, (2) last joint of the labial palpi deeply emarginate in 
front, and almost crescentic in shape, (3) tibie with distinct spurs; and, among other 
characters of less importance, (4) parapleura (metasternal episterna) along the inner 
suture with a furrow which in front is bent inwards in an almost rectangular manner 
(instead of an impression occupying almost the entire surface and becoming smaller 
behind, as in Statira), (5) eyes more convex than in Statira, (6) antenne with the 
apical joint scarcely one and a half times the length of the tenth. ‘I'wo species from 
Central America, Statira decorata, Makl., and a new one described here, agree exactly 
in these particulars*; but they also have the femora more or less clavate, of which no 
mention is made either by Kirsch or Maklin. In addition to these two species, three 
others from Central America agree in these characters, with the exception of the last 
joint of the labial palpi being simply triangular and not emarginate in front, and 
in the last joint of the antenne being very elongate in the males of two of them. 
These species must either be treated as congeneric-or separated into three genera ; 
the former seems to be the proper course, and the following diagnosis will include 
them all :— 
Last joint of the maxillary palpi securiform ; last joint of the labial palpi very broad and triangular—its apex 
concave-emarginate (very deeply so in C. decoratum, moderately so in C. foveiceps), or almost straight 
(C. calcaratum, C. sulcicolle, C. vitticolle); outer lobe of the maxillee short and very broad (much broader 
than in Statira); mentum extended on each side in front; ligula short and very broad, fan-shaped, 
extending laterally beyond the anterior angles of the mentum; mandibles furnished at the apex with 
three teeth (very long in C. sulcicolle) of equal length; eyes moderately large, convex, distant from the 
* Others from Peru and Brazil, apparently undescribed, are also known to me.
