rate excavation. An oval scarlet spot rests subterminally on the 

 median nervules ; above this is a small patch of pale blue scintil- 

 late scales divided centrally obliquely by the black scales which 

 cover the sub-costal nervure. Fringes black, except at extreme 

 apices. 



Under surface of anterior wings resembling upper, but the blue 

 scintillate scales encroach on and cover the basal scarlet patch infe- 

 riorly, also obtaining beyond it, and between it and the terminal 

 scarlet oval spot. The sub-costal scintillate patch is also larger. 



Posterior wings, black, with a brilliant dark blue shade, which 

 latter obtains principally at the base and along internal margin, 

 extending thence outwardly towards the middle and external mar- 

 gin. Under surface, resembling upper, but almost entirely covered 

 with paler blue scintillate scales of a variable shade. 



" Front," bright metallic blue. Palpi exceeding, and held hori- 

 zontally free from the front ; above, dull blackish ; beneath, bright 

 metallic blue. Antennae black, evenly pectinate ; the caputal sur- 

 face between them at base is covered with black scales ; behind, 

 with metallic blue scales. Thorax, above, dull blackish, overlaid 

 with blight blue metallic scales on the " collar," extending laterally 

 to the insertion of the wings, on the patagia inwardly, and on the 

 thoracic disc centrally. Beneath, a very prominent white patch 

 between anterior legs ; anterior femora, white on the inside ; legs, 

 bright metallic blue ; tarsi, dull blackish ; abdomen, dark metallic 

 blue, of hardly so violet a shade as secondaries above. The basal 

 glandular pouches are clothed above with longer mixed blackish 

 scales.

This narrower species differs from C. splendida, C. micans, 

 C. fnlgens, and C. fulgida, in the violet secondaries without 

 orange or scarlet tinges. The scarlet patches are broader and 

 differently proportioned compared with those of the Brazilian 

 C fastuosa, Menetries. The specific characters assigned to C. 

 jucunda, Walker, are scanty, but C. bivulnera seems to differ
