intervals between the rows flat and sparsely and very minutely 

 punctulate. 



This species is larger and less convex than P. gagatina Makl., 

 its prothorax is relatively a little broader, the rows of punctures 

 on its elytra are much finer, and it is distinguished further from 

 that species by its darker coloration and its glossy elytra.

Black, opaque, rugose, clothed with short yellow pubescence 

 interspersed with longish black hairs. The head (which has an 

 elevated shining median longitudinal line), prothorax, and elytra 

 all thickly and coarsely punctured ; the elytra dilated and widening 

 towards the apex. 



Each elytron ornamented with two long oval basal yellow mark- 

 ings, the marginal one joining a trausverse yellow band extending 

 to >uture, and with a second transverse band, starting from but not 

 quite touching the suture, extending down margin and curving 

 round across the apex of elytron back to the suture : these markings 

 are all margined by a fine brownish-red line. Antenna? red, with 

 the exception of the first and second joints, which are black. The 

 underside, legs, and tarsi are all black with long yellow hairs ; the 

 nails and spurs red. 



This species is rery similar to Mylabria hypolachna of Gestro 1 

 in size, form, and general characteristics, but it differs in having 

 the second transverse band continued along the outer margin and 

 thence across the apex to the suture.
