Coleojdem. 123 



characters : — Head speckled above with a number of small glabrous 

 brown spots, each of which surrounds a puncture. Pubescence of 

 elytra ashy white in colour at base, yellowish grey over the rest of 

 their surface ; each elytron with two snow-white spots — one under 

 the shoulder, similar to that in bilohis, the other, which is very 

 small, and surrounded with a naked brownish-testaceous border, 

 being placed on the disk beyond the middle. The two snow-white 

 spots, which in 0. hilohus are present on the disk near the base, 

 are in the new sjjecies wanting, their place being taken by two 

 glabrous spots, not very regular in outline, and therefore, possibly, 

 due to accidental rubbing. 



One male specimen, taken in the north part of the island.

 near the lateral margin ; the interspaces on the elytra between the 

 rows of spots are rather strongly punctured, and more or less-
