4. — BiojjJiida cvstata, n. sp. 

 (Plate VII, tigs. 13, 13rt, f^ ; 14, ? elytron.) 



Elonwatf, 9iil>parallel-sided, depressed, rather broad, moderately shining, 

 finely pubescent ; fusco-testaceous or brown, the month-parts, femora, and tarsi 

 in part, testaceous ; densely, finely, the elytra rather coarsely and confusedly, 

 punctate. Head transverse, much narrower than the prothorax, well developed 

 behind the eyes, foveate in the middle between them, the frontal suture 

 distinct, the eyes deeply emarginate and separated in the two sexes by about 

 their own width as seen from above; joint 4 of the maxillary palpi cultriform, a 

 little longer than 2; antennae filifoi-m, moderately long, rather slender, joint 2 

 much shorter than 3, the two together scarcely longer than -i, 4-11 sub-equal. 

 Prothorax broad, strongl}' transverse, rapidly, arcuately narrowed from the 

 middle forwards, the sides sub-parallel at the base, the latter sinuate, the two 

 basal foveae deep, the disc canalictilate down the middle behind. Elytra long, 

 sub-parallel, wider than the prothorax, rounded at the apex ; in the $ with a 

 sharply defined sub-marginal ridge extending from the humeral callus to near 

 the apex, the ridge becoming sinuous posteriorly, and curving inwards to the 

 middle of the disc at its point of termination. Legs rather stout ; tibial spurs 

 moderately long, thick ; penultimate joint of each tarsus widened and lobed, 

 deeply excavate above for the recei^tion of the claw-joint, the basal joint of the 

 posterior pair less than half the length of the tibia, the claws toothed at the 

 base. Length 7-8^, breadth 2^-2| mm. ( c? ? ) 



Eah.: E. Africa, S.E. Slopes of Kenya, alt. 6000-7000 ft. 

 {S.A. Neave). 



One pair, captured in February, 1911. A large, elongate, de- 

 pressed, broad form, Avitli a prominent sub-marginal ridge on the 

 elytra in ? , the head foveate between the eyes in both sexes, the pro- 

 thorax short and broad, with two deep basal foveae, and a short 

 median channel between them. The long, tubular, apically bilobed 

 process projecting from the tip of the abdomen in the larger costate 

 example seeuas to be an ovipositor, and not a part of the ^ armature. 



5. — Blo2>hida quinqv.efovecda, n. sp. 



Elongate, sub-parallel-sided, rather broad, flattened above, dull (till 

 denuded), finely pubescent ; brown, the head, antennae, and prothorax nigro- 

 fuscous ; head and prothorax densely asperato-punctate, the elytra more 

 coarsely, confusedly punctured, with the interspaces minutely punctulate, the 

 puncturing of the under-sui-face very fine and dense. Head transverse, narrower 

 than the prothorax, well d(;veloped behind the eyes, tiunid in the middle 

 posteriorly, the frontal suture distinct, the eyes separated by fully their own 

 width as seen from above ; joint 4 of the maxillary palpi stout, sub-cultrifonn.
