Remarkable for the straightness of tiie margin of the 

 elytra, which is more straight even than that of D. puJchella. 

 The present insect resembles 'pidchella in some respects, but its 

 pronotum is very differently sculptured — the sculpture hav- 

 ing an areolated appearance after the manner of that of D. 

 Spencei^ Waterh., and others — and the longitudinal sulcus 

 of the pronotum is in the hind part very much wider than 

 that of 'pidchella, and continues to widen quite to the actual 

 hind margin of the segment. The colour seems to change from 

 blue to green, according to the point of view from which the 

 specimen is looked at. The bidentation of the front tibiae is 

 of the character of the same in D. Edwardsi, rather than in 

 D. colaspidoides.

This species stands unnamed in the Macleay Museum. 

 It is of an obscure dingy-copper or bronzy colour, with dull 

 greenish reflexions, the green somewhat more pronounced on 

 the under-surface. It is especially characterized by the ex- 

 treme faintness of the quasi-areolation of its pronotum. It
