396 Records of the Indian Museum. [Vol. IV, 



concave in the middle, becoming broader at the sides; the under 

 side yellow at the base and black on the apex. Legs black, the an- 

 terior and middle femora and the middle and posterior tarsi yellow. 

 Wings clear, the dark colouring hardly perceptible at the extreme 

 base ; along the fore border it is narrow and only reaches the band, 

 the apex being quite clear ; the band hardly attains the hind bor- 

 der and becomes paler in the fourth posterior cell, only just con- 

 tinuing into the fifth; in some of the specimens it does not reach 

 be^^ond the fourth and never attains the anal cell : it is straight on 

 both its borders. 



Length 8^ mm. 



One of the specimens from Borneo does not measure more 

 than 6-| mm. Ricardo, Ann. Mag. Nat. Hist. (7), ix, p. 380. 



In Indian Museum coll. are females of this pretty little species 

 from Pallode, 20 miles N. E. of Trivandrum, Maddathorai, west 

 base of W. Ghats, all in Tra^ancore. The greyish stripe or band 

 below the antennae and a narrow border between the eyes and the 

 facial tubercles are in some ot these specimens almost golden yel- 

 low. The species is easily recognized by the long cylindrical 

 antennae, all the joints about equal in length, the black shining 

 face, and the attenuated band of wings usually not attaining the 

 fifth posterior cell, its outer border is rather concave in these 

 specimens. 



[This species, which is very common on the west side of the 

 W. Ghats in Travancore in November, resembles C. dispar (p. 382) 

 in habits. — N. Annandale.J

 wanting. Thorax shining black, with a large spot of fawn-coloured 

 tomentum in front of the wings and prolonged below; scutellum 

 black, bordered with testaceous colour Abdomen pale yellow, 

 the second segment with a blackish chevron, the last one black. 

 Posterior femora brown. Wings on posterior border and the 

 cross incised band biownish. From India. M. Bigot's collection.

This type is unknown to me. From the description it is not 

 clear whether an apical spot is present on the wing, but as it is 

 said to be related to C. translucens, Fabr., which possesses one, it 

 may be assumed to have one. From the description it might 

 possibly be a specimen of Chrysops dispar, Fabr., with the black 

 stripe almost obsolete. It is not included in the table.
