that it is a distinct species. Perhaps it is the female of 
D. rufescens. 
Type in the Paris Museum.

Diplatys ernesti, Burr, (1910!) p. 48, fig. 9. 
A small black Singalese species closely allied to D. 
gerstaeckert. It differs in the all-black colour and in the 
more obtuse and broader median triangular lobe on the 
posterior margin of the penultimate ventral segment of 
the male. 
Type in my collection.

This black and white species is characterised by the 
form of the penultimate ventral segment of the male, 
which is gently rounded at the sides, with the posterior 
margin slightly, but distinctly, convex in the middle; 
there is also a median depressed sulcus. 
It was originally described from Hong Kong, but prob- 
ably D. croiai, Burr, in the Paris museum, from Malacca 
Peninsula, and the Borneo specimen in the Budapest 
Museum, are to be referred here. 
It is unknown in Burma, Ceylon, and India, though 
specimens of D. greeni, Burr, from Ceylon, were confused 
with it; and probably, also, of D. bormansi, Burr, and 
D, liberatus, Burr, from Burma. 
Therefore, several mentions of D. nigriceps in literature 
really refer to one of those species, the synonymy of which 
should be examined. 
Type in the B.M.
