the apices sub-truncate ; they are without basal tubercles or crests, 

 and are dark-l)rown in colour \aried with pubescence of a yello- 

 wish tint usually forming spots or broken lines on the hinder 

 part of the elytra , an oljlique fascia on each sid(' before the 

 middle, and a narrow, transverse zig-zag band behind the middle. 

 Last ventral segment black or ])rownish-black ; the rest of the 

 underside covered with greyish or yellowisli grey pul)(^scence.

P. camurae (Newm.) persimilis sed plaga albida postica 

 elytrorum ad apicem extensa, pronoto hand albido-vitkito. 



Hab. Sumatra: Si Rambé {Modigliani). 



Very like P. camnra , New^m. (posticalis, PascJ in size, 

 structure and markings but differing 1) in liaN'ing no yellowish 

 white lines on the pronotum, the latter being covered with yel- 

 lowùsh-brown pubescence mottled with dark brown, and 2) in 

 the shape and position of the luteous-white patch on the posterior 

 slope of the elytra; this patch extends along the whole slope 

 from the end of the dorsal carinae up to the apex but does not 

 reach the outer margin except near the apex; whereas in P. 

 camitica it is of the nature of a transverse band reaching to the 

 outer margin but not extending more than half way from the 

 dorsal carinae tow^ards the apex.

D. circulatae (Paso.) persimilis sed tubercfdls sub-hasalibus

Long. 14-15, lai. mm. 



Hab. Sumatra: Si Rambé {Modigliani). 



This species greatly resem]:>les D. circulata Fase, both in 

 form and coloration but is easily distinguishable from it by the 

 character of the sub-basal tubercles of the elytra. These tubercles 

 are more strongly raised , somewhat conical in shape , and each , 

 instead of being capped with a dense tuft of black hairs as in 

 T>. circidata, is simply covered like the surrounding parts with 

 greyish-tawny pubescence. The curved white band wdiich crosses
