base of femora, abdomen and genitalia. Tegmina hyaline, slightly 

 opaque with waxy secretion, veins yellow on basal half, reddish brown 

 on apical half, apical veins and transcostal veins red, fuscous along 

 costal, apical and hind margins, subcostal and radial veins darker, 

 a dark mark at base of fourth median sector, two small marks in 

 clavus and one in median cell; wings hyaline, opaque with waxy secre- 

 tion, veins basally yellow apically fuscous. 



Ventral edge of pygophor straight, lateral edge slightly curved; 

 anal segment long, dorsal surface angular, sloping from middle to sides, 

 apex rotundate, anus at apex; styles long and narrow, apices rounded 

 and turned inward, ventral edge gradually produced into a short wide 

 angle about middle, dorsal edge produced into a small rounded process 

 near base and a small spine about middle. 



9 Second joint of antennae globose, covered with short sense or- 

 gans as in Kdha; posterior margin of last sternite angular, apex 

 turned upward into base of styles. Body lighter colored than male. 



Length 2. 5 mm. ; tegmen 4mm.

 I name this species after Mr. F. Leefman, to whose gnidanee 

 I owe some verv pleasant collecting tri]is.

From Bnitzenzorg, -lava, on palm trees, both sexes in num-

9 Antennae small, globous, with elevated sense organs and small 

 "scales", last abdominal sternite as in Irrfnniiiii.

This species was described from a single specimen with dam- 

 aged antennae. I can now recognize that it should be placed 

 with the above species. All three differ from the description 

 of the generic type in the form of antennae, but I think there 

 is some mistake, as peetlnata is described as having antennae 

 different from any Derbid yet known. I submitted specimens 

 of one of the al)Ove species to ]Mr. Distant, who considers it 

 distinct from Deeadeuida, but I shall await the opportunity to 

 examine the type before I erect a new genus.
