330 Mr. G. J. Arrow on the 
and 5th together. The club is short and broad. The elytra 
are deep violet in colour and ornamented with four large 
rounded yellow patches, which are separated in the longi- 
tudinal direction by an interval about half as wide as one of 
them, and in the transverse direction by a narrower interval.

There are two specimens, which I believe to be male and 
female, but which are identical externally. 
There is a close resemblance to D. borneensis, but the new 
species is considerably larger, the red patch upon the elytra 
is more extensive, although exactly similar in outline, and 
not divided along the line of the suture, the sides of the 
pronotum are less regularly curved, the front angles more 
abruptly contracted, nearer together and more acute, the 
lines of punctures upon the elytra much more irregular and 
the antenne more slender, with a less abrupt club, the ninth 
joint not broader than long. 
Lycoperdina mandarinea, Gerst. This widely-distributed 
species has been recorded from Tonkin by Fairmaire, but 
I have received no specimens from the region. 
Saula fuscicornis, Fairm. Tonkin: Hoabinh. The antenne 
of M. Vitalis’s specimens are black except at the base, and 
not brown, but this is not a distinction upon which it is safe 
to rely, as Cziki has done in his key to the species.
