Pygoccelis, gen. nov. 



Type P. africanuSj 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 mesosternura, 

 the anterior outline is feebly and rather widely arched and 

 sinuous on either side. The prosternum in Trijpeticus (type 

 T. gilolous, Mars.) is " nearly square " and slightly widest 

 at the base. 



Pygocoelis 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 Tryponceus and 

 Trypeticiis.

Pygocoelis diiplicatus^ sp. n. 



Cylindricus, niger, nitidus ; fronte minute strigosa, capita vertice 

 pnnctato, punctis hand densis ; pronoto punctato, stria lateral! 

 carinata, antice tenuiter impressa minute crenulata ; prosterno 

 antice striate, stria laterali antice abbreviata. 



L. 3f mill. 



Cylindrical, block, shining ; the head, face minutely strl- 

 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,
