Two males of this small but remarkable species w^ere jDresented 

 to the S.A. Museum by Mr. C. M. Bagot, who captured them. 

 Besides the colour, the shortness of the abdomen and the almost 

 microscopical smallness of the femoral spines are unusual.

There are four specimens in the collection of the S.A. Museum 

 (locality unrecorded) which agree fairly with the general character

 precise enough to settle the point. I append, therefore, a fuller 

 one based on my specimens, supjDlementing the former. 



Metallic green (male), dull blackish (female), or pale yellowish 

 (larva?), margins narrowly yellowish; dorsal surface finely scabrous 

 with scattered, elevated, smooth, shining, pale brown or yellowish 

 tubercles and ridges, the latter existing chiefly on the pronotum, 

 less on the meso- and meta-notum, forming various patterns diffi- 

 cult to describe. The abdominal segments ha%'e a row of tubercles 

 along the hindmargin and one or more in the middle, the bases 

 in the larvae being marked with a narrow black or metallic green 

 band. The hindmargins of the male are pale, of the female dark,
