CcELOCNEMODES, n. g. 
Habit of Ccelocnemis, Mann. Submentum rather strongly [pedunculate ; the sinus very 
open, exposing the base of the maxilla, its outer angle feebly dentiform : mentum broader than 
long, nearly plane, contracted posteriorly, sides and front angles broadly rounded from near 
the base, coarsely rugosely punctured, nearly covering the ligula, which is strongly transverse, 
and, apparently, broadly emarginate in front : last joint of labial palpi ovoid and truncate at 
apex; that of the maxillary feebly securiform: mandibles very thick, notched at apex: 
antennae having the first seven joints coarsely punctured and hispid ; joint 3 elongate, equal to 
4-6 united ; 4-7 equal, obconic ; 8-11 perfoliate, setose, clothed, except at the base, with a fine 
silky yellowish pubescence ; 8-10 moniliform, scarcely wider than long ; 11 longer and tapering 
to an acute point : head transverse, sub-quadrate, but little contracted behind the cheeks ; not 
prolonged behind the eyes : antennary orbits sub-angulate, prominent : epistoma rather short, 
gradually narrowed to the front, which is broadly emarginate with the angles distinct : labrunn 
strongly transverse, pilose, nearly entirely visible, very feebly emarginate in front, the 
angles rounded : eyes very narrow, flat, obsolctely faceted, anterior margin entire : prothorax 
moderately convex, a little wider than long ; sides well rounded, somewhat abruptly contracted 
near the base, narrowly but distinctly channelled and transversely rugulose, finely margined ; 
base and apex not margined, the latter arcuately emarginate, the angles broadly rounded, the 
former truncated, the angles distinct but not prominent, and reposing on the shoulders of the 
elytra : scutellum broadly triangular, penetrating between the elytra : elytra regularly convex, 
scarcely wider at base than base of prothorax ; oblong-ovate, rapidly declivous behind, the apex 
produced but scarcely mucronate ; shoulders depressed ; sides a little sinuous near the base, 
gradually expanding to behind the middle : epipleurce broad; the fold attaining the humeral 
angle, moderately broad, very gradually narrowed to the apex, which it attains : proslerna l 
jwocess closely curved round the coxse, and broadly truncated behind : mesosternum declivous, 
faintly concave : metasternum very short between the coxse ; the episterna narrow and but 
little contracted posteriorly ; epimera distinct : intercoxal process broad, truncated in front, 
angles rounded : legs moderate ; femora thickened outwardly, the 4 posterior a little com- 
pressed, the anterior with a strong tooth on the upper edge near the apex; all the tibia 
rounded, the anterior not denticulate at outer edge, and having a curved excision near the 
base on its inner side; the intermediate the same but more feebly : tibial spurs short, but 
stout : tarsi channelled and briefly spinose beneath, the first joint of the posterior much 
shorter than the last, upper surface granulous. 
Notwithstanding its peculiar habit, this genus unquestionably belongs to the Blaptides. 
As in this genus, so in many species of true Blaps, the ligula is almost entirely concealed by 
the mentum. The structure of the antennas is entirely that of the genus Blaps, and most 
closely approaches the form as seen in B. mortisaga, Linn. The short epistoma, leaving the 
labium almost entirely uncovered, the unmargined base and apex of the prothorax, the hind 
angles reposing on the shoulders of the elytra, also manifestly approach this genus to Blaps.
