median one of which is edged by two blunt tubercles on each side ; 

 elytra subquadrate, truncate behind, broader than the prothorax by 

 one-third, with the shoulders sloping slightly and the outer margin 

 curving slightly inward, irregularly and deeply punctured except 

 along the outer margin, which has a regular series of very broad 

 punctures, discoidal part with three series of elongate, not much 

 raised and blunt wart-like tubercles tinged with black at apex, the 

 outer one of which develops in a curved carina overhanging the 

 shoulder ; under side totally black. Length 4 mm. ; width 2^- mm.

PLATYPRIA MASHUNA, n. sp. 



Pale yellow, shining, antennae rufescent, with the two basal joints 

 black ; head black ; prothorax broader than long, faintly impressed 

 transversely along the base, pale yellow with four nearly always dis- 

 tinct black or fulvous round spots in the centre, provided on each 

 side with a subvertical series of six sharp spines radiating from an 

 alveolated process, the four median spines are long, tipped with 

 black, the anterior and posterior ones are very short, and the angle 

 of the base is also spiniform ; elytra subquadrate, very deeply and 

 broadly punctured, and having two discoidal series of black spines 

 on each side, those on the median part longer than the others, and 

 a marginal one the spines of which are still longer than the dorsal 

 ones, the four sub-humeral spines of this marginal series are ramified 

 at the base, and they are infuscate at the tip, the fifth one is placed 

 at some little distance from either those preceding or following, and 

 is also infuscate at the tip, while the post-median ones are quite 

 black ; the suture shows faint traces of spicules, and at the base of 

 every dorsal spine there is a rounded black patch ; under side 

 deeply infuscate, legs pale yellow. Length 7-7-J- mm. ; width 

 4-4-g- mm. 



The black dorsal patches on the back are sometimes obliterated.

In shape and length of the spicules it resembles altogether P. 

 masliuna, but the size is always smaller, the colour of the upper part 

 is testaceous, the black dorsal patches are broader in proportion to
