P.ferniginea is very closely allied to the typical specie? 

 of the genus, P. vitfalata, Fairm., but rather narrower iti 

 shape, with the ground-colour rusty brown instead of red. 

 The whole surface is very finely and rather closely punctured, 

 and the elytra are more deeply striate-punctate. Each elytron 

 has the extreme outer edge and four narrow longitudinal 

 lines black, the outermost line extending* almost to the suture 

 but not uniting with the others, which also remain distinct 

 at their extremities.

 conjunctis, plerumque ante medium haud apparentibus, iuterdum 

 etiam linea intermedia vestigiali antica ornato ; corpore vix 

 punctato, prothorace quam longitudiuem vix latiore, lateribus 

 ad basin paulo divergentibus, postice fere rectis, basi regulariter 

 arcuato, angulis posticis acutis ; elytris postice acuminatis, Isevis-

This is very near P. rufoviitata, Har. (described as a 

 species of Megalodacne) . It is rather more oval in shape and 

 more pointed behind, the sides of the prothorax are more diver- 

 gent behind and the hind angles sharper, and the elytra are 

 very lightly striated, without visible punctures in the stria3 

 or between them.
