yellow transverse line in its centre at the base. The other segments are broadly black 

 at the base. All the coxae bear a black line on the outside ; all the femora, trochanters, 

 the four anterior tibiae and tarsi, and the basal half of the hind tibiae are black above. 

 Areolet longer than wide, the outer nervure distinct and nearly joined to the 

 recurrent nervure. 



Not unlike P. chontalensis, but the metanotum is not strongly punctured and the 

 spines are much longer, thinner, and curved.

Antennae much longer than the body, pilose ; third joint considerably longer than 

 the fourth. Head black above the antennae, except the orbits broadly ; frontal spine 

 longish, thick, not tapering much towards the apex ; thr^ee carinae, not very distinct, 

 lead to it from above ; eyes not distinctly margined. Sides of the prothorax black and 

 longitudinally striated ; above black, except a broad yellow line on the edge. Meso- 

 notum black ; two lines in the centre, more than the apic&l half of the scutellum and 

 its keels, yellow. Pleurae below the wings black. The centre of the metanotum broadly 

 in the middle at the base black, the black continued as a narrow line down the pleurae, 

 and in the middle as a broad stripe ; a narrower line down the sides from the spiracles 

 (joined to the middle stripe by a short transverse line), arid a small line over the hind

 upper transverse keel distinct, the lower obsolete ; spines loiig, stout. First abdominal 

 segment black, except at the apex and laterally; second segment with a large black 

 mark, dilated at the apex like the segment itself; the other segments broadly black at 

 the base. A broad line on all the coxae, a line over the four anterior legs and also 

 over the hind trochanters and femora, and the hind tibiae, entirely, black. Areolet 

 longer than broad, the outer nervure quite distinct.
