PYGOC@LIS, gen. nov. 
Type P. africanus, Lew. 
This genus is established to receive certain African species 
allied to Trypeticus. The head is recumbent and the forehead 
declivous ; the pygidium wholly concave; the prosternum 
twice as long as wide, widest anteriorly ; the mesosternum, 
the anterior outline is feebly and rather widely arched and 
sinuous on either side. ‘The prosternum in Zrypeticus (type 
T. gilolous, Mars.) is “ nearly square” and slightly widest 
at the base. 
Pygocelis africanus, Lewis. 
The specimen from which the original description was 
drawn is somewhat immature; the examples before me now 
are dark, almost black ; the prosternum is punctured and the 
surface rough; the punctures of the mesosternum are elon- 
gate and subaciculate. In six examples I fail to find any 
sexual characters such as those seen in T'ryponeus and 
Trypeticus. 
Hab. Yogoland and Cameroon. 
Pygocelis duplicatus, sp. n. 
Cylindricus, niger, nitidus; fronte minute strigosa, capite vertice 
punctato, punctis haud densis; pronoto punctato, stria laterali 
carinata, antice tenuiter impressa minute crenulata; prosterno 
antice striato, stria laterali antice abbreviata. 
L. 33 mill. 
Cylindrical, black, shining; the head, face minutely stri- 
gose, vertex punctured, punctures not close, evenly placed ; 
the thorax rather longer than broad, depressed behind the 
eyes, anterior angles somewhat rounded off, surface punctured, 
punctures shallow, not very dense but evenly set, marginal 
stria carinate laterally, complete anteriorly and minutely 
crenulate ; the elytra punctured like the thorax; the pro- 
pygidium clearly and rather thickly punctured ; the pygidium, 
punctures much larger and proportionally close; the pro- 
sternum as long again as wide, with a marginal (obsoletely 
crenulate) stria in front ; laterally there is no stria anteriorly, 
but for about two thirds from the base there is a fine irregular 
stria, and in the lateral median region there is a longitudinal 
shallow furrow or impression, surface microscopically strigose,
