ations of the lateral margins) in addition to the usual transverse 

 depression in front of the middle. From P. macularia, Pasc. 

 (which I know only by description) it seems to differ by the 

 presence of ochraceous pubescence, of a well-defined longitudinal 

 line on the head, and of evident elytral costse, as well as by the 

 absence of a smooth glabrous line on the prothorax ; from 

 P. miliaris, Pasc, by the presence of white as well as ochraceous 

 pubescence on the elytra, the shape of the scutellum, &c; and 

 from P. pullina, Pasc, by its elytra not having "two prominent 

 costse marked at intervals by coarse tubercles." Its colours and 

 markings are as follows: — on aground of whitish pubescence 

 ochraceous pubescence occupies the hind part of the head, runs 

 forward between the antennae (not extending to the eyes) and 

 spreads out on the front of the antennal tubers, is distributed in 

 a kind of linear reticulation on the prothorax and runs similarly 

 over the disc of each elytron but is almost absent on the marginal 

 sutural and apical portions ; the whole upper surface is studded 

 with small black spots (evidently smaller than those of 

 P. melanosticta and much smaller than those of P. scenica) which 

 on the front of the elytra are raised granules but elsewhere are 

 even with the general surface.
