Labium almost exactly as figured for Dicterias atro sanguine a (Monog. 

 Calopt. pi. 8, fig. 12). 



Abdomen 35-36 mm., hind wing 28.5-29 mm.

9. Thorax as above described for the males but without any prui- 

 nosity. Abdomen evidently much faded, but apparently it was of a 

 pale color without black stripes or markings. Abdominal segments 8 

 and 9 of nearly equal length dorsally, 10 half as long as 9 with a mid- 

 dorsal carina for its entire length, hind margin entire. Appendages a 

 little longer than 10, straight, simple, tapering, apices very acute. 

 Genital valves reaching caudad almost to the level of the hind end of 

 11 (anal tubercle), their " palps" subequal in length to the mid- 

 dorsum of 10. 



Venation as described for the Chapada males except as follows : 

 point of separation of M 1+2 from M 3 only one cell distal to the level of 

 the distal end of the quadrilateral on the front wings, one cross-vein in 

 the median area of all the wings, only one basal subcostal cross-vein 

 on the wings of the left side, both front and hind. 



Abdomen 33 ; hind wing, 29.5 mm.

As will be seen from the above descriptions, these three specimens 

 not only combine some features of H amazona and of H libera 

 Selys, but also differ in some respects, e. g., the extent of petiolation 

 of the wing, from the characters laid down for the genus. So few 

 specimens of Heliocharis have been examined, however, that we are 

 not yet in a position to say which of the venational differences are in- 

 dividual variations and which represent more fundamental features. 



15. Chalcopteryx rutilans Rambur. 



Prof. Needham has figured the venation of this brilliant species in 

 the Proceedings of the United States National Museum, xxvi, p. 729, 

 fig. 22, 1903.
