 margin. The figure of the antenna is taken from a 

 specimen from Amula, Guerrero.

 Journ. N. York Ent. Soc. xx, pp. 255, 272. 



(^. Antennae with joint 1 strongly curved, convex within, con- 

 siderably widened outwards, rounded at the outer apical angle; 

 2 angularly dilated at about the middle externally, the appendage 

 short and slender. 



Hab. United States, Arizona. 



The antennal characters are taken from a male from 

 Nogales sent by Mr. Nunnenmacher to the British Museum. 

 This insect has the head wholly black, dull, and densely 

 punctate, the two basal joints of the antennae almost 

 entirely testaceous, the bluish-green elytral spots not 

 reaching the outer margin, and the femora and trochanters 

 rufo-testaceous. The southern C. femoralis, Gorh., is, of 

 course, a different species.]
