 front wing, one or two in hind wing; distal thickened ante- 

 nodal the fifth ; anal angle well developed in the male, the tri- 

 angle 2- or 3-celled (the venation of C? dcmcrarae known to 

 me only from de Selys' brief description).

 M. Menger at Bruxelles through the good offices of Dr. F. Ris.

 conchinus, n. sp. Notice in fig. 10 the curved basal projections of 

 the superior appendages which overlap the broadened base of the

 the superiors above and the inferior below.
