any other described, but the prosternal (except that they do 
not meet in front) and mesosternal strie resemble those of 
P. cyanipennis, Fahy. 
Hab, Zanzibar (Raffray). 
Note.—Pachycrerus Bocandet, Mars., P. cyaneipennis, 
Fahr., P. morulus, Lew., and P. frater, Lew., form a small 
group in the genus in which the mesosternum has no marginal 
stria on the anterior border: P. Bocandet, Mars., is known 
from the others by having the thoracic stria complete; in 
P. cyaneipennis, morulus, and frater the stria is interrupted 
behind the neck; in P. frater the fifth dorsal stria is some- 
times evanescent before the base. 
Ilister Colensot, sp. n. 
Breviter ovatus, convexus, niger, nitidus; fronte minute punctu- 
lata, stria antice recta; pronoto bistriato, striis parallelis, margine 
ciliato; elytris striis 1-3 integris, 4—5 apicali-punctiformibus, 
suturali antice late abbreviata; prosterno in medio angustato 
haud striato. 
L. 82 mill. 
Shortly oval, convex, black, shining; the head very 
minutely punctulate, stria complete, straight anteriorly, 
vertex smooth; the thorax, outer margins ciliate, lateral rim 
very finely carinate and continued as a stria behind the head, 
but is widely interrupted behind the neck, outer lateral stria 
runs parallel to the margin, has a narrow interstice, and 
ceases after passing the anterior angle, inner stria complete 
and parallel to the outer one, interstice wide save in front ; 
the elytra, outer humeral stria absent, inner deep and shortened 
before the base, 1-8 complete, 4—5 represented by a few very 
fine apical points, sutural dorsal turning from the suture 
apically ; the propygidium and pygidium punctate, but the 
points are not closely set, apical edge of the latter smooth ; 
the prosternum, keel before the coxe narrow, without strie ; 
the mesosternum is feebly sinuous, stria complete, also 
sinuous and close to the anterior edge; the anterior tibiz 
strongly tridentate, the others spinose. 
The species should be placed next to HZ. robusticoll’s, Lew. 
It belongs to Marseul’s first division. 
Hab. Ulundi, Natal (Marshall). A stercoraceous species 
(no. 428). 
Hister planiformis, sp. 1. 
Ovalis, parum convexus, niger, nitidus; fronte impressa, stria 
integra; pronoto stria laterali interna haud interrupta, externa
