lesser development of the inferior branch. The inferior ap- 

 pendage is higher and curved forward farther so the enclosed 

 space at the apex, as seen in profile, is vertical rather than 

 horizontal as it is in tristaui. Superior appendages yellow or 

 yellowish, shading into black at the apices of the various 

 branches; the inferior dark, almost black, shining reddish 

 brown. In the specimen of, tristani given me by Dr. Calvert 

 the ventral branch of the superior appendage, as seen in 

 profile, is more triangular and more sharply set off than in the 

 type specimen, as figured by Calvert. 



Legs as described for tristani, except that the pale under 

 color of the middle femora is greenish brown, darker and 

 duller than the under color of the first femora, and this color 

 is not limited to a distal spot on the middle femora, but is con- 

 tinuous the length of the femora. 



Female. — Head, thorax and abdomen as described for 

 tristani; the coloration of head and thorax essentially like that 

 of the male. Segments 3-10 badly faded and discolored, more 

 or less blotched with brown and black; the median dorsal 

 stripes on 3-6 nearly or quite obliterated, seen here and there 

 as minute spots or short thread-like lines of color; the basal 

 lateral spots on 3-6 are obscure but discernible ; on 7 the pale 

 areas in the blotched pattern are greater in extent than on 

 3-6, but in its discolored condition no description is possible, 

 and unfortunately no living color notes were made of this 

 specimen; 8-10 are progressively darker, 8 being largely red- 

 dish brown, and 10 being largely black. Vulvar lamina as in 

 tristani. 



Male and Female. — ^Wings clear in the male with yellow- 

 ish tinges basally to about the level of the triangles; yellow- 

 ish smoky tinged throughout in the female. . Antenodals of 

 front wings 15-16, of hind wings 11-12; postnodals of front
