segment of c? very large, ample and smooth, nearly square, much 

 broader than the abdomen, yellowish brown ; sides somewhat 

 converging posteriorly, posterior margin truncate ; in $ ample, but 

 narrower than the abdomen, truncate posteriorly. Penultimate 

 ventral segment of d" ample, somewhat narrowed posteriorly, the 

 sides straight and converging ; posterior margin gently sinuate, 

 with a triangular depressed area m the middle ; in 2 narrow, 

 acutely convex. Forceps with the branches iu the cT strongly 

 flattened throughout their length and almost sulcate above, 

 strongly dilated at the base itself, this portion ending abruptly in 

 a blunt tooth, as the branches are sharply attenuated near the 

 base and diverging, then strongly arcuate, so as to enclose a 

 slightly transverse oval area ; in the $ the branches are simple, 

 straight, contiguous, tapering.

Pig. 3. — Apex of abdomen of male, showing penultimate ventral segment 

 and forceps, from beneath , of six species of Biplatys. 



A. D.falcatus. 



B. D. Irfroyi. 



C. D. anrjiisfatus. 



D. D. gersi(pchen. 



E. D. ei-)iesfi. 



F. D.flet chert. 



This is a fine species, which most nearly approaches the African 

 D. macrocephala, but the penultimate ventral segment is of a 

 diflferent shape, and the forceps are very strongly arched. 



Perhaps de Borraans included this species in his D. macrO' 

 cephala from Burma.
