6. Diplatys lefroyi, sp. n. (Fig. 5.) 



Eelatively large, General colour blackish brown, body reddish. 

 Antennae brown, yellowish near the base, blackish towards the 

 apes. Head black, the frous tumid and smooth, the transverse 

 suture obscure ; postocular keels sharp and distinct ; median 

 suture distinct only near posterior margin, which is depressed, as 

 also the occiput. Pronotum of d about as broad as long, irregularly 

 pentagonal, with rounded angles ; anterior margin roundly convex; 

 posterior roargin truncate, sides gently converging so that the 

 pronotum is somewhat narrower posteriorly than anteriorly ; 

 prozona black ; metazona yellowish. Scutellum yellow. Elytra 

 ample, smooth, black. Wings long, smooth, black. Legs yellow, 

 banded with blackish. Abdomen blackish red, gently widening 

 posteriorly. Last dorsal segment not very strongly dilated, about 

 half as wide again as the middle of the abdomen, rather longer 

 than broad, smooth, tumid, black with yellowish pubescence. 

 Posterior margin simple, gently sinuate in the middle, the sides 

 obliquely truncate. Penultimate ventral segment ample, rounded, 

 the posterior margin gently sinuate. Forceps with the branches 

 stout and trigonal, not very much depressed ; at the very base 

 itself the inner margin is produced into a depressed triangular 

 tooth, which is best seen from below, as it does not extend beyond 

 the edge of the last dorsal segment, and so is not easily visible 

 from above ; the branches are gently tapered, nearly straight or 

 gently incurved, the points scarcely hooked ; the interior margin 

 in the apical portion is denticulate ; the basal portion of the 

 forceps is pale yellow, the apical portion black.

This species is related to D. falcatus. The dilation at the 

 base of the forceps is so short that it is not at first noticeable, 

 and thus the forceps appear to resemble those of D. bormansi. 

 The penultimate ventral segment also is different from that of 

 D. falcatus, being rounded or sinuate, thus approaching the African 

 D. macrocephala, but the last abdominal segment is very little 

 broader than the abdomen. 



7. Diplatys angustatus, sp. n. (Pig. 6.) 



Size small, general colour black. Antennae black with a yellowish 

 ring near the base ; IG segments, all cylindrical, third rather short. 

 Head black, tumid ; occiput depressed, with sharp postocular
