half of the surface but being interrupted by the humeral oallus 

 (which is of a goklen copper color) and a little contracted at its 

 apex externally ; it is bordered except at the base and the front 

 part of its lateral edge by golden copper color. The pattern and 

 colors of the upper surface do not appear to be variable. 'I'he 

 underside is for the most part of a dull olivaceous tint, and is 

 more or less closely covered with small scale-like pubescence ; in 

 some examples the underside (especially the metasternum) is in 

 parts of a decided green. Toe head is somewhat convex and is 

 longitudinally impressed between the eyes. The prothorax is less 

 than half again as wide as it is long down the middle, its base, 

 which is bisinuate, being about a third as wide again as its front 

 margin, which also is bisinuate ; the true margin is very slightly 

 arched and is strongly bent under the head and front. The three 

 little elevations (each bearing a pencil of pubescence) near the 

 apex of the external margin oE the hind tibiae are a conspicuous 

 character. 



Very different from iV. chrysopygiiis. Germ., in the markings of 

 its elytra and other characters. Gisseis cuprifera, Gestro, is 

 probaljly a member of this genus, and must be very close to 

 Germar's species.

The spots of white pubescence on the elytra and hind body are 

 arranged as in the preceding species. The color of the elytra is
