Coraia is a form which, by its almost quadrate thorax, its 

 long and robust antennas, and its parallel body, reminds us of a 

 Longicorn. It is allied to Monocesta, but differs from all the 

 species composing that genus : it is elongate and very parallel, 

 instead of being (as in many species of Monocesta) broad and 

 apically dilated ; the antennas are relatively considerably longer, 

 and the form of the thorax is different. The genus Coraia is 

 related to Ccelomera and Monocesta by the bipectinated unguiculi 

 of the foot, by the relative lengths of the joints of the antennas, 

 and by the broadly transverse depression on the disk of the 

 thorax. Coraia differs from Galleruca (inter alia) by the greater 

 relative length of the antennas. It may be separated from Nes- 

 tinus by its much more robust antennas, the third joint of which 

 is equal to the fourth (in Nestinus the fourth being the longer), 

 in its parallel form of body, and in the form of the thorax ; the 

 anterior angles closely embrace the sides, being depressed in 

 position, not subporrect.

Not an uncommon species in Mexico. I have received it 

 under the name of astuta, Chevr.
