-BHYPHUS. 555 



infuscated over the 2nd longitudinal vein just beyond the prsefurca, 

 on the base of the 3rd vein, on the anterior and posterior cross- 

 veins, and on the outer side of the discal cell ; whilst very pale 

 brownish infuscations of larger extent occur below the stigma, 

 contiguous to it, more or less over the middle portions of the 

 longitudinal veins from the 4th, more conspicuous on the two 

 upper branches of this vein, and on the two branches of the 5th. 

 Halteres pale yellowish. 



Length 4-5 millim. 



Described from several specimens of both sexes in the Indian 

 Museum from Simla, 7000 ft., 24. iv.07 and 10. v. 09, and Matiana, 

 Simla district, 8000 ft., 28-30. iv.07 (both Annandale); Darji- 

 ling, 5-9. viii. 09 (Paiva); Kurseong, xi. 1910 (D'Abreu) also 

 from Ukhrul, Mauipur, Assam, 6400 ft. (Pettigreivi). 



The main difference in this variety, which I am almost inclined 

 to rank as a separate species,* from typical fenestralis is the colour 

 of the thorax, with its stripes, and the wing-markings. The apical 

 wing-spot in fenestralis (typical) (PI. XII, fig. 3) is brownish, its 

 inner sides forming a right angle, and at the edge of the wing the 

 spot extends distinctly below the 3rd longitudinal vein; whereas 

 in indicus (in life) it is much blacker,t the edge is much more 

 clearly cut, and the distal half of the spot does not extend below 

 the 3rd longitudinal vein, although above this vein it reaches the 

 wing-tip as usual, so that the inner sides of this spot do not 

 form a right angle, but are irregular.

c? 2 . Head : vertex blackish grey, with a few bristles. Pro- 

 boscis and palpi blackish brown. Antennae black, extreme tips of 

 scapal joints slightly whitish. Thorax moderately light grey, 

 with pale hairs ; the usual three dorsal dark stripes, the outer 

 ones considerably shorter, the median one attaining the anterior 

 margin ; the hinder part below the dorsum yellowish ; scutellum 

 grey. Abdomen moderately dark brown, with rather numerous 

 yellow hairs ; hind margins of segments pale yellowish. Belly 



* The comparison was made between the set of Indian examples mentioned, 

 about twenty in number, and a number of European female specimens in the 

 Indian Museum, and my own collection from England, Wales, Scotland, and 

 Austria. 



t The colour fades to brown in specimens a year or more old, and perhaps 

 this is the case with most species of Hhyphus.
