African Species.* 



Upper posterior tibial spur simple 



Upper posterior tibial spur subulate at tip 



18. — Scirtes sitbcostatus, n. sp. 



5 . Oblong-oval, broad, sbining, thickly pubescent ; fusco-testaceous or 

 brownish-piceous, the head and prothorax darker in one example, the antennae 

 piceous, the three basal joints, the legs, and under surface testaceous ; densely, 

 finely, the elytra a little more coarsely, punctate. Antennae long, slender, 

 joint 3 distinctly longer than 2, 4-11 elongate. Prothorax very short, rapidly, 

 arcuately narrowed from the base, bisinuate in front. Elytra long, sharply 

 margined, feebly tricostate. Posterior coxal plates transverse, arcuato- 

 emarginate behind, angulate at the outer angle. Posterior tibiae widened, 

 feebly curved, sharply carinate, the upper spur strongly curved, stout, shorter 

 than the first tarsal joint. 



Length 5^-6, breadth 3| mm. 



Sab. Uganda, Entebbe {S.A.Neave: ll.ix.l911 ; C. C. Gowdey. 

 xii.1912, and iii.1913). 



Described from two females ; a third example taken by Mr. Gowdey, 

 probably 6 , is somewhat injured. A large, broad, oblong-oval, brownish 

 insect, with the elytra feebly tricostate, not unlike a Microcara. S. costu- 

 latus Waterh., from Penang, and S. costtdipennis Fairm., from Tonkin, 

 are somewhat similar forms, with more densely sculptured elytra. 



19. — Scirtes zambesianus, n. sp. 



$ . Oblong-oval, broad, shining, pubescent ; rufo-castaneous, the elytra 

 becoming a little paler towards the apex, the antennae, legs (the infuscate 

 posterior knees excepted), and under surface testaceous or rufo-testaceous ; 

 densely, finely, the elytra more coarsely, punctate. Antennae long, slender, 

 joints 2 and 3 short, subequal in length, 4-11 elongate. Prothorax rapidly 

 narrowed from the base, the anterior angles prominent. Elytra long, with an 

 indication of four almost obsolete costae on the disc, narrowly margined. 

 Posterior coxal plates arcuato-emarginate behind, angulate at the outer angle. 

 Posterior tibiae widened, sharply carinate, the upper tibial spur long, shorter 

 than the first tarsal joint. 



Length b\, breadth 3-3|^ mm. 



Hab. Zambesi {Mus. Brit.). 



Two examples, in somewhat decayed condition, received by the 

 Museum in 1877. Very like S. subcostatus from Uganda, rufo- 

 castaneous above ; the antennae rufescent ; the el^'tra less rounded at 

 the sides, and the costae only just traceable. 



* Of the seventeen recorded African forms, one only, S. giganteus Champ., is known to me. 

 The eight hart enumerated are treated as new. One other before me, from Nyasa, is too imperfect 

 for description.
