DICRANOMTIA. 379 



forming the stigma, square in shape, ending just beyond the 

 marginal vein, and contiguous to a round one over the origin of 

 the 3rd longitudinal. Basal and distal sides of discal cell, with 

 posterior cross-vein, just perceptibly infuscated. 



Length 5-6 millim. 



Described from three females from Darjiling, 5-8.viii.09(P<Mva). 



Type in the Indian Museum. 



Although so closely related to D. puncticosta, this form seems 

 sufficiently characterized by the three distinct thoracic stripes 

 (although absent in one individual), the black ring on all the 

 femora, and the clear, not yellowish grey, wing, with a less 

 number of markings. 



267. Dicranomyia fascipennis, sp. nov. (PI. VII, fig. 9.) 



$ . Head : frons narrow, with back of head dark grey, the 

 latter with pale hairs ; proboscis dark brown, palpi blackish ; 

 antenna3 brownish yellow. Thorax dark yellowish grey, with a 

 median, barely darker brownish stripe, ending at the suture. 

 Scutellum and metanotum, also sides of thorax, yellowish brown. 

 Abdomen dark brown, with very short sparse pale hairs. Legs 

 uniformly brownish yellow. Wings clear. Auxiliary vein ending 

 immediately before the base of the 2nd longitudinal, which begins 

 just beyond the middle of the wing; the 1st longitudinal ending 

 just before the middle of the marginal cell ; marginal vein 

 distinct, placed exactly at the bend in the 1st vein where it 

 turns up to the costa, this section of it being very indistinct, 

 making it appear as though the 1st vein turned downwards at its 

 tip, meeting the 2nd vein ; praefurca less than half as long as the 

 remainder of the vein, tip of vein turned sharply upwards at tip ; 

 basal section of 3rd vein two and a half times as long as the 

 anterior cross-vein, which latter is as long as the basal side of 

 the discal cell ; discal cell nearly oblong, slightly broader towards 

 the tip, three times as long as broad, rather longer than the 2nd 

 and 3rd posterior ceils ; posterior cross-vein in a line with base of 

 discal cell. The markings of the wing consist of pale grey spots 

 placed as follows : At the base of the 4th vein ; near the middle 

 of the 4th vein, situated so as to be in the middle of both basal 

 cells ; at the base of the 2nd vein ; on the marginal cross-vein, 

 forming the stigma; and near the tip of the 7th vein. All the 

 cross-veins are narrowly infuscated, as is also the tip of the 

 2nd vein and base of the 3rd vein. Halteres whitish, clubs 

 black, small. 



Length 3 millim. 



Described from one female from Kurseong, 5. vii. 08 (Dr. 

 Annandale}. 



Type in the Indian Museum. 



The example is a female, and was perfect when identified as a 

 new species, but before being described the apical segments of the 

 abdomen were accidentally lost.
