including marginal cross-vein ; tip of 2nd vein ; tip of anterior 

 branch of 4th ; tips of 5th and 7th veins ; base of 3rd vein, 

 the spot extending over the anterior cross-vein ; and the posterior

Hedescribed from two males and two females in the Indian 

 Museum, from Darjiling, 6. viii. 09 (Paiva) ; Mazbat, Mangaldai 

 district, Assam, 11-15. x. 30 (Kemp) and Peradeniya, Ceylon, 

 5. viii. 10 and J5. x. 09 (Green). There is a female in the Vienna 

 Museum, also from Ceylon. 



Type c? in the Amsterdam Museum. 



Meijere described only the male. The species varies con-

Libnotes rufa, Meijere, Tijd. Ent. liv, p. 39 (1911). 



S $ . Head bright orange-yellow ; proboscis and palpi brown ; 

 antennae formed as in L. fuscinervis, dark brown, except the 

 brownish yellow scape. Thorax and abdomen, with belly, bright 

 orange-yellow ; dorsum of abdomen with the faintest trace 

 of a very narrow black line. Genitalia resembling those of 

 L. fuscinervis, with a rather small, narrowly conical organ between 

 the claspers and the ventral sheath. Legs mainly pale orange- 

 yellow ; fore femora black on distal three-fourths, posterior femora 

 black towards tips ; tarsi black at tips. Wings clear grey ; costal 

 cell, as far as the dark brown stigma, and base of wing 

 orange-yellow in male, black or blackish in female ; veins con- 

 colorous. Venation as in L. notata, Wulp. Halteres yellow; 

 clubs black. 



Length 11 millim. 



Eedescribed from specimens in the Indian Museum from 

 Calcutta, 5. viii. 08 (Annandale), and Peradeniya, Ceylon, 13 and 

 17. vii. 10 (Gravely) ; also from two in my own collection from 

 Calcutta, taken by me. Mr. E. E. Green has also sent specimens 

 for identification from Ceylon. 



Type 5 in the Amsterdam Museum. 



In Osten Sacken's table of Oriental species the present one 

 would be separated from L. imponens, Walk, by the orange-yellow 

 (not piceous) abdomen, the yellow veins and the absence of the 

 long black stigma ; but this latter character would not so easily

 Java), but there can be little doubt, the male attributed here to 

 his species is really the other sex, being quite identical in all 

 respects except for the striking difference in the colour of the 

 costal cell. In this species, in the specimens that have come 

 before me at least, the 1st longitudinal vein seems to fade away 

 at its tip instead of turning up as usual into the costa, and as the
