Tegmina light yellow, opaque with waxy secretion, veins on basal 

 half yellowish, on apical half reddish, especially media and 

 median sectors; a large, round, black spot at apex over fourth 

 median sector, dark fuscous over basal half of costal cell, shad- 

 ing off into subcostal cell, dark fuscous over hind edge of clavus ; 

 wings fuscous, veins dark. 



Ventral edge of pygophor straight, lateral edges slightly ar- 

 cuate ; anal segment longer than width at base, slightly narrow- 

 ing toward apex, which is roundly emarginate, anus just before 

 apex; genital styles reaching to end of anal segment, narrow, 

 curved slightly dorsad, apex rounded, a small angular projec- 

 tion about middle on inner surface. 



Length, 2.3 millimeters; tegmen, 4.

Genus KAHA Kirkaldy 



Kaha Kirkaldy, Ent. Bull. Hawaiian Sugar Plant. Assoc. (1906), 1, 



433. (Feb. 3.) 

 Devadanda Distant, Fauna Brit. Ind., Rhyn. (1906), 3, 315. 



Kirkaldy's work above quoted bears the date of publication, 

 February 3. The exact date of publication of Distant's work 

 I do not know, as the volume only bears the date of 1906, the 

 introduction being dated February, 1906. It is highly prob- 

 able that the publication of Kaha antedates that of Devadanda, 

 because the introduction to Distant's work must have been 

 written at least several days before the day of publication. 



Devadanda differs from Kaha in the shape of the antennae, 

 a character which cannot be taken as of generic importance, as 

 there is much specific and sexual difference in this group. The 

 former genus was founded upon a single specimen, the sex of 

 which is not mentioned, but it is probably a male ; I do not think 

 the description of the antennse is morphologically correct, as the 

 condition described is not found in the Derbidae or in the 

 Fulgoroidea. 



Nesokaha differs from Kaha in having the vertex and face, in 

 profile, forming a continuous curve or with only a small angu- 

 lation at the junction of vertex and face, the face not prolonged 

 in front; the antennae are simple in both sexes. It is possible 

 that the two genera will have to be united. 



Kaha flava sp. nov. 



Female. — Yellowish; vertex and basal portion of face trans- 

 parent, apically fuscous red, darkest between eye and middle 

 of face; clypeus and lateral portions of pro- and mesonotum
