almost an cfiiiilatcral triauf^lc : niaiulihlcs densely scinaniosc; 

 (oeea-sionally bare — /*. s/xirsKs, l''lis., and P. loiniulns, Holi.), 

 luiiltisetosc, with n distinct median tootli, the sear variaijle ; 

 mentnm with nnmeions erect setjo on the anterior half, 

 nsnallv arran^'ed in a tnlt ol'thrce to six oneaeh side, the basal 

 hair snnk in the cavity ; scrobes passinj^ mcII below the 

 eves, more or less s(|uamosc. AutcinKe with the scape 

 slender, clavate, reaching; abont the middle of the eye; 

 t'nnicle S(|Uamose, j(nnt 1 nuicli longer than 2 (except in 

 /*. slri(/ifru/is, Fhs., in which they are eqnal). Prothorux 

 variable in form, bnt always tiansversc and narrower at the 

 apex than at the base. Scu'el/um invisible. Sieriium with 

 the pillar margin more or less sinnate, the coxie about 

 in the mitldle of the prosternuni ; nu'sepisterniun usually, 

 but not always, separated (rom the elytron by its epimeron ; 

 metasternnm much shorter than the mid-cox;e, with a more 

 or less distinct antecoxal fold, the episternal suture com- 

 j)leie, the episternnm not pnMluced inwardly at the base and 

 lajjidly narrowin};; to a point behind, the hind coxie touch- 

 ing the elvtra. I'enf^r with the intercoxal process narrower 

 than the coxre, slightly angulate or gently rounded ; hind 

 margin of segment 1 shallowly sinnate, segment 2 much 

 longer than 3, Leys with the corbels of the posterior j)airs 

 of tibiie si|uamose or bare, veiy oblique, with the upper 

 fringe of setie ascending the dorsal edge of the tibia in a 

 straight line, and the extreme apical edge narrowly enclosed 

 (except in P. spu?'sus-aud its allies) ; claws connate. 



In the males the elytra are narrower than in the females ; 

 the first ventral segment is very slightly impressed, and the 

 last is shorter and more broadly roniided ; in some species 

 the legs are maikcdly stonier than in the females. 



(lenotyi)e, Strojihosomvs crucijrons, Boh. 



Distinguished from true Strophosomus by the setose 

 nientum.the squamose mandibles and antenna?, and the very 

 oblique corbels of the hind tibite. 



Apart from the sj)ecics here assigned to the genera Pro- 

 scephalaitcres, Braclnjbainoii , Po)iip/u/:<, and Leiirops, all the 

 African " Stropluisomus''' known to me fall within the present 

 genua; and, judging by the descriptions, this is also likely 

 to prove true of -i>. nticorifrons. Boh., rotiiiidicollis, Boh.,
