This species is very easily recognisable when alive by the 

 metallic pattern of its elytra, which consists of a well defined 

 wide subsutural vitta (more or less completely interrupted in 

 front of the middle of the length of the elytra) and a similar 

 vitta placed just within the lateral margin of the discal portion 

 of the elytra (this vitta abbreviated in front), the two of a metallic 

 golden or green colour and confluent at the apex of the discal 

 part of the elytra. There is also a small metallic patch on the 

 shoulder. The parts (of the discal portion of the elytra) that are 

 not metallic are of a piceous tone ; the marginal portion is 

 testaceous. 



Dried specimens may be at once distinguished from nearly all 

 other species of the subgroup by the head being black at its base, 

 the black colour extending forward far enough to reach beyond 

 the level of the back of the eyes. The head is similarly coloured 

 in the species that I have called hitnaculata, Oliv., but the latter 

 is not at all closely allied to the present insect, being of a much 

 less wide form, notably less strongly convex, with the punctures 

 of the elytral series less symmetrical and notably finer, &c., &c. 

 Apart from colour, P. vitatta is closely allied to P. decolorata, 

 Chp., from which, however, it differs by its evidently wider form, 

 metallic elytral pattern (in the living specimen), extensively black 

 base of head, and (in dined examples) generally darker tone of 

 colour.
