Female. Body almost uniform pale yellow ; antennal tubercles and the space between 

 the antennae, blackish ; antennie long, slender, filiform, the last joint blackish, and 

 l)ointed, vertex transverse, raised, with a rounded elevation on each .side, between which 

 and the eye is a blackish .spot. Pronotum about twice as long as broad, gradually 

 widened behind, a brown line on each side at the base, parallel, and another jiair^ 

 diverging towards the extremity ; a black irregular band interrupted at the sutures 

 passes from the back of the pronotum over the middle of the meso- and meta-notum ; 

 the pleura is also marked with a broad black line. Abdomen with slender and in-^ 

 complete brown or blackish lines in the back and on each side ; it is densely clothed 

 with short hair, especially towards the extremity. Front legs pale yellow, femora 

 thickly clothed with longer black hair and raised slender bristles on the ai)ical half ; 

 tibia? with three rows of a very few long, slender diverging black bristles : terminal 

 spines of equal length, and extending to the third tarsal joint ; the remaining legs- 

 wanting. Wings hyaline, lirilliantly iridescent, with a pink shade in some lights, and 

 irregularly varied with pale ochraceous, especially towards the marginal area of the^ 

 apical third. Fore wings very slender at the base, very broad at two-thirds of their 

 length, and obtusely pointed. Many of the cross nervules in the costal area are double 

 at their base, where they are marked with a pale ochraceous spot. Two oblique black 

 irregular transverse stripes, one near the base, and the other before the middle of the 

 wing ; the latter shades into ochraceous above, below, and in the middle. A row of 

 irregular and interrupted ochraceous and blackish markings also crosses the wing at 

 three-fourths of its length. Hind wings longer, narrower, and produced into a point- 

 at the extremity ; the space between the hyaline portion of the wing and the apex 

 is irregularly varied with brown ; and the outer third of the inner margin is ochraceous, 

 slightly marked with brown on the inner side ; and before the inner end of this- 

 ochraceous border an irregular ochraceous mark, varied with brown above, is thrown 

 up for about one-third of the width of the wing, the whole inner area of which is 

 other\^-ise entirely hyaline. 



Entebbe, March 24th, 1900. 



DiiFers from all the described species of this curious genus by its pale colouring, 

 and pattern, as well as in the comparatively long, slender antennte, which hardly 

 accord with the short clubbed antennae which are usually characteristic of the family 

 Mj/rmeleonidce.
