Head comparatively shorterand, seen from in front, rounder than in P. dypcuta ; clypeusmore convex and much more strongly carinate, anteriorly producedinto a rectangular lobe as in P. ch/peata, but the anterior margin,though transverse, is not dentate. Thorax broad in front, narrowposteriorly, the pro-mesonotal suture broad and deep, the meso-metanotal suture marked by a transverse carina; the prouotum.

Nodeof pedicel l3iconvex, thicker than in P. clypeaia, and quadrispinousas in that species, but the lateral spines are broader and placedhigher up on the node, and the two medial spines are reduced toobtuse teeth and placed much closer together; abdomen broadlyo\al. 2 . Very similar to the ^ , the stria; on the head and thoraxcoarser, the pronotum laterally obtusely angled; the basal portionof the metanotum transversely rectangular, its posterior marginwidely emarginate, the lateral angles slightly turned u]); theabdomen longer and more massive; the soft fine sericeous recum-bent pile much denser, especially on the abdomen, and of a reddishyellow.
