angle to the other, and finally, it differs in the elytra by the 

 larger and closer excavated depressions. The upper tooth on the

17. — Carenum scitdlum. 

 Nigrum nitidum, thorace subquadrato antice truncato postice 

 rotundato medio canaliculafco transversim subrugoso, elytris

 extus bidentatis.

The head in this species is a good deal wrinkled in front, and 

 has the facial grooves connected together behind by a curved de- 

 pression. The thorax is a little broader than long, nearly trun- 

 cated in front and rounded behind : along each lateral margin 

 there are three setigei'ous punctures, while the disc is covered 

 with transverse scratches. The elytra are green, and of an oval 

 shape truncated in front, and with a large puncture on each not 

 far from the apex. The surface is glossy, though when seen 

 under a lens it appears to be marked with several wavy strice. 

 The fore tibiee are bidentated externally. 



This insect is unique in the Australian Museum, and is 

 marked " Statchbury, North District." It is probably from 

 Moreton Bay or Port Curtis.

 Nigro-cyaneum nitidissimum, thorace lato valde marginato, 

 abdomine ovato, elytris puncto versus apicem impressis,

 than the thorax, convex, and almost perfectly oval ; there is a deep 

 puncture on each near the apex, and a row of smaller punctures 

 in each lateral margin, with a few small punctures on the base. 

 The fore tibiae are tridentate externally, the upper tooth being 

 much smaller than the others.
