One spécimen, collccted in California by M. Child, and given me 

 by M. Rathvon. The markingsare on the same plan as those of the 

 pi'cceding species , but ihey are not dilated along the siiiure, 

 and the anleiior is broken up so as to form a roundet spot each side 

 behind the humérus, and a larger less distinct one at the suture, 

 The liner punctuation of the thorax, and the black feet, will enable 

 it to be readily recognised.

One spécimen from Oregon, Col. M'Call. The posterior angles of 

 tlie (borax are long and acute; the third joint of the antennœ is 

 equal in length to thefourth, but is notât ail dilated. The last joint 

 is wanting, so (bat \ve cannot be certain that it belongs to this divi- 

 sion (I); ils gênerai appearance, however, prevents it from being 

 placed in any other. The front is slightly concave, not showing the 

 quadrate outline which may be perccived in the others of this 

 group.
