Imago. — <£$. No constant difference in colour from C. hylas. 

 In fresh specimens the upperside of head, thorax and abdomen 

 pure green instead of yellowish, but the green fades to yellowish 

 in time ; red abdominal belt very often narrower, sometimes 

 even absent, and individuals often rather smaller and less 

 robust than those of hylas. Fore tibia ending in a prominent 

 rust-coloured thorn. Expanse : <$ 50-66 mm., $ 70 mm. 



$. Ninth and tenth segments asymmetrical, tenth sternite 

 moved towards the right side ; tenth tergite (fig. 64 D) 

 divided by a longitudinal groove, the two halves separated 

 only at the tip, slightly tapering apicad, so twisted that the 

 right lobe lies higher than the left one, the latter the shorter ; 

 sternite curved, lanceolate. Right clasper very large, ventral 

 part of inner surface covered with black hairs ; left clasper 

 narrow, sides nearly parallel, apex somewhat dilated, sub- 

 truncate, ventral angle more rounded than upper one. Penis- 

 funnel large (fig. 64 E).
