STTKINGOMTIA. 463 



bristly at the base, rather more than half as long as the 6th, 

 sharply curved near its tip towards the border. A slight brownish 

 suffusion over the anterior cross-vein, the outer side of the discal 

 cell, and the posterior cross-vein. Halteres dirty yellow; knobs 

 blackish. 



Length 3-6 millim. 



Originally described by Mr. Edwards from a single male from 

 Weligama, Ceylon, 9.ii.08 (T.Bainbriyye Fletcher); here redescribed 

 from a pair in the Indian Museum taken in cop. at Sukhwani, 

 Nepal, 15.-16.ii. 08 ; a pair in cop. horn Puri, Orissa, 10. xi. 10 

 ( Annan J ale) ; a pair in cop. taken at light 30. vii.10 (Gravely); 

 a pair taken at Sukna, Darjiling district, 500 ft., 1. vii. 08 (Annan- 

 dale) ; and from other specimens. 



Type 3 in the British Museum. 



The above description was written some months before the 

 publication of Mr. Edwards' S. ceylonica, under the assumption 

 that it was a new species, having been drawn up from a 

 series of more than a dozen specimens representing both sexes. 

 The species shows considerable variation, and a form which 

 I had intended to describe as a variety has the wings more 

 yellowish, the veins paler and the tip of each one very slightly 

 but distinctly darkened at the wing-margin. In the Indian 

 Museum, are one male and three females from Sukna, 500 ft., 

 1. vii. 08, Puri, Orissa, 22. x. 08 (both Annandale), and Calcutta, 

 9. xii. 07. I took it at first for a " plains " variety of my 

 supposed new species, but intermediate individuals connect it 

 with the typical form. Dr. Annandale says it rests with its 

 anterior legs stretched out flat in front and its hind legs behind. 



The precise mathematical distinctions appertaining to the 

 bands on the legs, as given by Mr. Edwards do not hold good, as 

 they exhibit considerable variation. The "bristly hairs" men- 

 tioned in the above description are sometimes (especially those 

 on the neck, shoulders and pleuras) sufficiently strong to be 

 termed real bristles.

3 . Head : frons brownish yellow, antennal scape dark brown ; 

 flagellum (of fourteen oval joints) yellowish, pubescent ; palpi dark 

 brown, pubescent ; proboscis brown ; back of head light reddish 

 brown, with some bristly hairs. Thorax: neck (with strong 

 bristles), dorsum of thorax, scutellum and metanotum uniformly 

 dark brown ; traces, on hinder part of dorsum, of a pale median 

 line, extending over the scutellum and metanotum. Two rows of 

 dorsal bristles as in S. ceylonica, and a few bristly hairs above and 

 in front of the wings. Sides and lower part of thorax brownish 

 yellow. Abdomen moderately dark brown, minutely pubescent,
