agrees so well with Walker’s description (as far as it goes) that I 
have little doubt in referring it to this species, and from it the 
following fuller description is drawn up. Being, however, im- 
mature, it may really belong to the next species notwithstanding 
their widely distant habitat, Wc. 
Black. Head reddish brown. Antenne brown, middle portion 
above third joint black. Pronotum smooth, shining, with a few 
distant impressed dots ; margin all round pale yellow; disk black, 
oval. Meso- and meta-notum similar, the black discal spot form-

This species belongs to the same type as the preceding and 
P. trifasciata, Tepp., but differs from both not only in the color 
marks, but in various other more essential details.
