296 Mr. H. W. Bates on the 
behind, and the hind angles are not quite rectangular, with 
the points scarely prominent. The elytra are ovate, con- 
vex and very glossy, "with a large black patch over the 
suture, which is sometimes smaller and behind the middle, 
and sometimes oblong extending nearly to the base ; there 
are four jDunctured stria?, the first three of which are very 
strongly impressed, but the third ceases before the apex, 
and the fourth, deep at the base, becomes faint, and dis- 
appears beyond the middle of the elytra ; there are traces 
of a fifth at the base. The usual punctures on the third 
interstice are small and indistinct. 
Although the locality of the variety and its appearance 
are very distinct, I have failed to find the smallest struc- 
tural difference from the type.

Very similar in form to P. areolatus, but conspicuously 
longer, and with distinct large punctures on the disk of 
the thorax. The colour is imiform testaceous-tawny, or 
rather darker, ?'.e., testaceous-brown ; the basal joints of 
the antennas and the legs in either case being a little paler. 
The elytral stria? on the sides and at the apex are more 
completely obliterated than in P. areulatus.
