inclusion of the two additional species. I also give a table 
differentiating the species. 
Ligula short, wide, truncate at apex, bisetose: paraglosse 
very narrow, adnate to near apex of ligula and projecting 
only a little beyond it. Mentwm moderately excised, sinus 
oblique at sides, with a short wide triangular tooth : epilobes 
rather pointed at apex and extending a little in advance of 
lobes. Palpi stout: labial with penultimate joint bisetose ; 
apical joint short, hardly longer than penultimate, compressed, 
truncate: maail/ary with apical joint short, hardly longer 
than penultimate, obtuse at apex. Labrum shagreened, 
truncate, sex-setose. MJandibles short, without seta in scrobe, 
pointed at apex, serrate along lower half of internal margin, 
right one with a small median tooth. Clypeus bisetose. 
Head small; front deeply and shortly bi-impressed ; eyes 
hemispherical, narrowly separated from buccal fissure beneath. 
Antenne short, moniliform, lightly incrassate ; joints 1-3 
glabrous, 6-11 compressed, first large, about as long as 
second and third together, second shortest. Prothorax widely 
transverse, considerably wider at base than apex ; basal 
angles obtuse ; margins more or less bordered ; two marginal 
setee on each side, anterior just before middle, posterior at 
basal angle. lytra with bordered base ; apex sinuate and 
with margin interrupted on each side by an internal plica; 
no scutellary striole, interval 3 impunctate. Prosternum 
smooth ; intercoxal process more or less bordered. Metepi- 
sterna much longer than wide, punctate. Ventral surface 
more or less punctate along sides. Legs short: anterior 
tibiee with wide apex, rounded and spinose externally : tarsi 
short, glabrous on upper surface, joint 5 glabrous beneath, 
claws simple: anterior tarsi (¢) with joints 1-3 moderately 
dilated and biseriately squamose beneath, 1-2 triangular, 3 
rather more quadrate, 1 shorter than 243, 4 very small: 
anterior tarsi (2?) with joint 1=2+4+3+4, first two joints 
with apex produced internally into a spiniform process: 
posterior tarsi slender, joint 1=2+3+44: posterior tro- 
chanters with a setiferous pore near base. 
The genus is allied to Celostomus (Stomonazus), but the 
antenne are more slender, tle thorax wider, nearly as wide 
as elytra, flatter, hardly contracted behind, median line and 
basal sulci much fainter, border less reflexed, elytra flatter, 
hardly contracted towards base, strie impunctate.

1 (4). Prothorax with front and side margins 
bordered throughout, basal margin un- 
bordered, surface smooth.
