Vertex very slightly transversely depressed, length at middle 

 equal to that at eyes, anterior margin carinately elevated, a dis- 

 tinct circular brownish yellow depression between ocellus and eye 

 on either side ; ocelli equidistant from eyes and each other ; front 

 moderately inflated, disc broad, flattened-convex, transverse rib- 

 bing interrupted in median line by slight longitudinal depression; 

 pronotum three- fourths wider than long, disc strongly convex, 

 distinctly transversely wrinkled, two distinct pits behind elevated 

 anterior margin near median line, lateral to which and directly 

 posterior to inner angles of eyes are two circular brownish yellow

 C. delicata var. (i) lineata Ball. 



Vertex slightly depressed transversely in median line, depres- 

 sions lateral to tylus reaching entirely across it, a distinct, circular, 

 yellow depression midway between ocellus and eye on either side, 

 anterior margin carinately elevated, bordered from eye to eye with 

 black; eyes margined behind with black; ocelli equidistant from 

 eyes and each other ; front strongly inflated, disc sharply, rounded 

 convex, rising abruptly from face at sides ; face entirely black 

 (subvar. b), yellow above, transversely marked with interrupted
