and 5th tofjcthcr. The club is short and Ijroad. The elytra 

 are deep violet in colour and ornamented with four lar<je 

 rounded yellow patches, whicli are separated in the longi- 

 tiuliual direction by an interval about lialf 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 

 pronotuni 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 anteunaj more slender, with a less abrupt club, the ninth 

 joint not broader than long. 



Lycoperdma mandarinea, Gerst. This widely-distributed 

 species has been recorded from Tonkin by Fairmaire, but 

 I have received no specimens from the region. 



Saulafiiscicoi-nis, Viurm. Tonkin: Iloabinh. The antenna' 

 of M. Vitalis's specimens are black except at the base, and 

 not brown, but tliis is not a distinction upon which it is safe 

 to rely, as Cziki has done in his key to the species.
