Var. The head with a spot on either side of the vertex and a broad stripe down the middle in front black; 
the thorax with a short median vitta, a spot at the sides in front, and some indistinct markings near the 
hind angles (in addition to the usual spot on either side of the middle of the disc), black; the elytra with 
the discoidal stripe greatly extended (only separated from the suture and lateral margin by a narrow 
border of the ground-colour), in two examples eoalescent with the basal spot; the underside and legs 
(the coxze and the extreme base of the femora excepted) black.

Hab. Muxtco®, Chilpancingo in Guerrero (H. H. Smith), Yautepec, Plan del Rio 
(Hoge), Oaxaca (Sallé, coll. F. Bates). 
We have received about forty specimens of this species, of which six belong to the 
var. clavipalpis. Varies greatly in the extent of the black markings on the thorax 
and elytra, and in the colour of the underside and legs, also in size, from 83-25 millim. 
P. clavipalpis only differs in colour, and an example of it was obtained at Yautepec 
with one of the palest forms of P. divirgata. 
In the palest specimens the elytral vitta is very narrow, in some specimens abbre- 
viated anteriorly, and the basal spot is obsolete or nearly so. ‘The femora and tibie 
may be yellow, with the tips only black. ‘The variety clavipalpis has the black greatly 
extended on the elytra, a short median vitta and some additional spots on the thorax, and 
the underside and legs almost black. The elytra are thickly, minutely punctate, and. 
have some widely-scattered, shallow, coarser impressions. The antenne always have 
their basal two or three joints pale. The last joint of the maxillary palpi is very 
stout and obliquely pyriform in the male. The much longer, smoother, differently- 
marked thorax, non-sulcate elytra, and different male-characters separate P. divirgata 
in all its varieties from P. tenwicostatis.
