stripe is again a little wider on the pronotnm, bnt here reduced to two oblong spots, 

 one apical and the other basal, the sides of the pronotnm also bearing some rnsset 

 pubescence. In contradistinction to the other species of Physopterus descriljed 

 from Africa [si'lci/ro/is Fahrs. (1839), dorsoeittis Kolbe (1895), and inelanoleucus 

 spec, nov.] the pronotum is only depressed behind the carina, the centre of the disc 

 being convex, apart from a slight flattening in front of the carina; the carina 

 resembles that of P. dorsovittis. None of the interspaces of the elytra are raised, 

 and all are jiractically of the same width ; there are no tufts ; the base, sides, and 

 apex are more or less rnsset, while the sutural area from the subbasal depression 

 to the apical declivity bears numerous greyish white spots, some being continent, 

 others isolated, the spots extending anteriorly and posteriorly to the fifth inter- 

 space, while they are restricted to the sutural interspace in the middle. The 

 underside is grey, with the sides of the prothorax broadly black ; the metasternum 

 bears a russet lateral patch. The tibiae have two grey rings, which are sharply 

 defined, the greater part of the first and fourth tarsal segments also being u-rev. 



The rostrum is broader than in P. dorsovittis, the carinae are sharply marked, 

 being convergent from the eyes forward and then divergent ; the space between 

 them is broadly depressed, bearing a median sulcus at the base and a slightly 

 raised median line near the apex, the sulcus being replaced on the frons by a thin 

 carina.

Although very close to S. gitineemis Kolbe (1895), which also occurs at 

 Bailundn, the present insect is undoubtedly specifically distinct. It is narrower 

 than ffuineensis, the intercoxal process of the mesosternum is shorter and the 

 process of the metasternum consequently longer, the latter proces.s beino- lonfer 

 than it is broad, while in guineensis it is broader than loug. The abdomen is 

 rather more coiwsely punctured, particularly the last three segments, and, in the S, 

 more deeply depressed. 



The upperside is pubescent black, with an inconspicuous intermixture of grey, 

 and variegated with definite Inteons grey spots. The prothorax bears about fourteen 

 spots: the largest spots on the elytra are ])laced in interspaces 3 and 5, viz. one 

 behind the base, a second in the middle, and a third at tiie commencement of the 

 apical declivity, the suture and interspaces 7 and 9 being conspicuouslv dotted 

 with luteous grey. The greyish white median ring of the tibiae is sharply defined.
