Mr. A. Gr. Butler on new Sjjecies o/Tlaty pleura. 389 



I conclude that tliis cannot be the ordinary female of P. 

 gigas, since it differs niarkedlj from that species in size, 

 pattern, and coloration, in addition to the structural distinc- 

 tions above indicated. Should it prove to be so, the species 

 would stand alone and distinct, even from its nearest allies, 

 in having a female unlike itself; there is, in fact, extremely 

 little variation cither in form, pattern, or size, in individuals 

 of the same species of Platypleura^ at any rate, so far as my 

 experience goes. I therefore regard the female before me as 

 a distinct species, more nearly allied in structure to P. Came- 

 roni than any other form yet described.

2 S- Antananarivo [Wilh). Type, B.M.. 



This species has the general coloration of P. semiclara of 

 South Africa ; the tegmina are formed as in P. gi'gas^ with 

 similarly expanded membrana costte ; the pattern of the mark- 

 ings on the tegmina is also as nearly as possible identical ; 

 the wings, however, are smaller, the face is shorter, the ante- 

 rior angles of the pronotum more oblique, and the entire body 

 narrower ; the drum-flaps are shorter, formed as in /•*. mada- 

 yascariensis ; the preanal ventral plate is decidedly narrower 

 and longer ; the rostrum (as in P. gigas) extends to a point 

 between the femoral articulation of tiie last pair of legs.
