complete, inner liinii('r;il and 1-8 dorsal stron<;, complete, and 

 similar in having the outer edge somewhat elevated, the third 

 dorsal is rather less strong than the secoad, 4 dorsal and the 

 sutural are fine and almost complete, being joined anteriorly, 

 bur they are slightly shortened apically, 5 dors.il is apical,

fine, and reaches just beyond the middle. The propygidium 

 and pygidium are clearly punctulate; the prosternum is bi- 

 striate, stria? divergent posteriorly ; the mesosternum is like 

 that of the last species, except that the fine marginal stria is 

 conspicuously complete anteriorly ; the metasternum is striate 

 laterally and the suture is marked by a line transverse stria ; 

 the legs are similar to those of P. africanus.

Proholostemus minor, sp. n. 



Ovalis, parum convexus, niger, nitidus ; fronte punctulata, stria 

 laterali perspicue anguluta ; pronoto stria latorali Integra ; elytris 

 striis 1-4 suturaliquo intcgris, 4 cum suturali arcuatim connexa, 

 o basi abbreviata ; prosterno bistriato, striis utriuque divergenti- 

 bus ; mesosterno stria marginali antice Integra. 



L. 3 mill. 



Oval, rather convex, black and shining; the head punctu- 

 late, punctures varying in size, with very minute points 

 intermixed, lateral stria rather strong and very distinctly 

 angulate in the middle, area behind the epistoma is very 

 faintly impressed; the thorax punctured like the head, except 

 along the base, where the punctures are larger, lateral stria 

 entire and feebly creimlate behind the neck; the elytra, the 

 stria? resemble those of J^. permutiduSj except that the fourth 

 and sutural are not shortened at the apex, the surface punctu- 

 ation is only seen under the microscope and consists of 

 extremely fine points ; the proj^ygidium is margined laterally 

 with a very fine stria, surface clearly nut closely punctate, 

 with very tine points intermixed ; the pygidium is curiously
