Atherix intermedia, mihi, sp. nov. 



cf . West Bengal. Long. 8^ mm. 



This species closely resembles both limhata of Osten Sacken 

 and my recently described calopa, and takes an intermediate posi- 

 tion between the two. 



From limhata it is distinguished by an all-black thorax, with 

 a little whitish shimmer on the humeral parts, round the edges of 

 the dorsum and in front of the insertion of the wings ; also by an 

 oblique, whitish stripe on the sides of the thorax, which, otherwise, 

 are wholl}^ black, as is also the scutellum. The legs are black ; the 

 fore femora (except base and tip ), the apical half of the middle 

 femora, the middle tibise wholly, and the hind femora are yellow, 

 but the latter bear a broad, deep, black band, occupying about 

 the middle half of their length. The wing has a large, very 

 distinct blackish brown stigma, whilst the cross-band on the wing 

 is much darker. The abdomen is differently coloured, closely 

 resembling that of calopa, except that the posterior half of the 

 4th and 5th segments are occupied by a whitish band, which is 

 invisible from certain points of view. The basal half of the 5th, 

 and the whole of the 6th segment, is black. 



From calopa, the broad band on the hind femora easily sepa- 

 rates it, this character being consistent in the ten specimens ex- 

 amined. The wing marks also distinguish it by the prominent 

 stigma and the much more distinct apical part. 



Described from ten cf cf in excellent condition taken by Dr. 

 Annandale, i6-iv-09, ^^ ParesnathHill, West Bengal, at an altitude 

 of 2,000 ft., on rocks at the edge of a small jungle stream, where 

 it was present in large numbers. 



N.B. — This is evidently a good species, the ten specimens 

 agreeing exactl}^ in all particulars, whilst the three examples of my 

 calopa are also consistent; limbata of Osten Sacken, however, 

 according to him, appears to be variable. My present species is 

 best described as possessing the abdomen of calopa with the wing 

 of limhata, with the addition of an all-black thorax and a large, 

 black stigma.
