ASTYCUS. 135 



deeply sinuate and more strongly reflexed. The genitalia of tlie 

 J , however, afford a satisfactory specific distinction. In cliryso- 

 chlorus the male organ lias a distinct median dorsal carina; from 

 a lateral aspect the outline forms a regular curve both above and 

 below, being deepest at about one-fourth from the apex. In 

 Jlavovittatus there is no dorsal carina ; the dorsal outline is sinuate 

 at about one-fourth from the apex, the ventral outline being 

 sinuate quite close to the aj^ex ; the depth is uniform from near 

 the base to beyond the middle, diminishing thence to the apex.

 slightly dilated towards the apex, the apical margin with a broad
