Dr. Malcolm Burr’s Revision of the Genus Diplatys. 43 
This species is founded on a single male, now in the 
British Museum, which is one of the original specimens 
taken by Fea in Burma, and recorded by de Bormans 
under the name of Nannopygia gerstaeckerr. 
It is more nearly allied to D. nigriceps, but the subanal 
plate is not convex: the rectilinear pronotum distinguishes 
it from that species, and also from D. rufescens. The 
forceps are short, broad and flat, thus approaching the 
two following species.

This is a small jet-black West African species, re- 
D. aethiops. 
sembling the Central American D. severus in colour and the 
structure of the head.

In the British Museum there is a specimen from Dar-es-

My inability to place this species in its true position 1s 
just retribution for the unpardonable offence of describing 
a new species without possession of an undoubted male. 
The original description includes two distinct species ; 
the true D. viator is a dull black female from Madagascar, 
nearly hairless, with a long and narrow pronotum. 
The male attributed to it is from Fernando Po, but the 
apex of the abdomen, with the essential characters, is 
missing ! 
The pronotum is short and rather broad, obtusely
