" Olivaceous-grey, or brownish grey, with clove-brown mark- 

 ings ; dorsum of thorax with 2 pairs of clove-brown longitudinal 

 stripes (outer stripes broader and widely interrupted at transverse 

 suture), and a less sharply defined median stripe ; dorsum of abdo- 

 men with a clove-brown median longitudinal stripe, extending 

 from front margin of 2nd to be^'ond middle of 4th. segment, narrowly 

 interrupted before hind margins of 2nd and 3rd segments, a pair of 

 transversely elongate dusk}' blotches on ist segment, a pair of large 

 clove-brown spots on 2nd segment and a pair of similar but smaller 

 spots on 3rd segment ; wings slighth' infuscated, light sepia coloured ; 

 legs clove-brown, bases of tibiae ochraceous-buff . ' ' 



The types of this species are in the British Museum taken 

 at Kasauli, Punjab (W. Himalayas), "on cows" [Lt.-Col. F. 

 Wyville Thomson^. ' ' The flies sucked the animals, and their abdo- 

 mens became distended with blood. I have never noticed them 

 biting man." Mr. Austen compares his species to the European 

 H. stimulans of Meigen, distinguishing it b}' " its usually somewhat 

 smaller size (average length of 6 cf cf , 575 mm.), by the median 

 dark dorsal stripe on the abdomen being practically^ continuous 

 throughout its extent instead of widely interrupted before reaching 

 the hind margins of the 2nd and 3rd segments, by the 4th abdominal 

 segment in the cf being always without a pair of dorsal spots, 

 and by the ist longitudinal vein being either entirely bare or having 

 at most one or two minute bristles, instead of a row of bristles con- 

 spicuous under a strong lens when viewed at a low angle from the 

 direction of the hind margin of the wing. ' ' 



N.B. — One & in the Indian Museum, taken io-viii-09 by 

 Mr, Paiva at Darjiling (7,000 ft.), agrees almost perfectly with 

 Mr. Austen's description. Incidental!}', I may note that, previous 

 to reading of his species, I had marked this specimen as a variety 

 of stimulans. ]\Ir. Austen however mentions six specimens that 

 show consistency in the markings. The lesser size I do not value 

 as a specific character as I have noticed that Oriental specimens of 

 v^er}' common European species appear to be generally undersized. 

 The intrinsic value of the minute spines on the bases of the ist 

 and 3rd longitudinal veins, when present, is also, to my thinking, 

 much less than some writers have considered it.
