 Feronia (Pterostkhus) vagepunctata, White, I. c. p. 4. 



Port Nicholson ; also Christchurch. 



I obtained an example from M. Doue's collection named Platysma 

 subcenea, which is evidently authentic, agreeing with the author's description 

 and the types of vagepunctata of White.

valde dilatatis et dentatis. Subseneo-nigra, nitida ; thorace magno, quadrato, 

 postice perparum angustato, ante basin vix sinuato, angulis posticis paulo 

 productis ; elytris brevibus profunde striatis, striis punctatis et passim (pra>- 

 cipue postice) subinterruptis. Long. 8 lin. M.

thorax rather longer than in that species. The thorax is very nearly as long 



as broad, and is somewhat regularly and slightly rounded on the sides, the 

 greatest width being in the middle ; behind it is very much less sinuate, and 

 the hind angles are less produced than in subcenea ; the basal fovea also is 

 larger, and offers on its outer slope a distinct second smaller fovea ; but some 

 trace of tbis is visible in well-developed examples of subcenea. The hind legs 

 are remarkably short, and the femora are widely dilated beneath, forming a 

 tooth, between which and the base is lodged the elongated trochanter. 

 One example ; in my own collection. Exact locality unknown.
