Types in the British ^Museum ; o^ captured l)y me at Calcutta, 

 S-ii-og ; $ from ^Nlussoorie, ix-06 [HowleU]. Other specimens in 

 the British Museum from Allahabad, 6-X-05 [Hoivlett] ; Sylhet, 

 i3-iv-05 [Hall]; and Henaratgova and Haldumulla (both Ceylon), 

 7-ii and i4-vi-92 respectively [Ycybury]. In the Indian Museum are 

 3 d' cf from Tharbani, Nepal, 27-ii-o8; and from the base of 

 the Dawna Hihs, Lower Burma, 2-iii-o8 [Annajidale]; 3 cf c^ from 

 Bandra (Bomba}' Presidency) '' hovering in slaughter house," 

 28-xi-09 [Hodgart] ; and one 9 from Maddathorai (base of Western 

 Ghats, Travancore, i7-xi-o8 [Annandale]. I have a <f in my own 

 collection taken b}' me in Calcutta, i8-ii-05. Both Dr. Annandale 

 and the Museum Collector Mr. Hodgart have noticed the apparent 

 habit in the males of this species of hovering, an unusual practice 

 of the members of this subfamily, although I have occasionally 

 noticed it in Stomoxys calciirans. 



N.B. — Although the s])ecinien forming the type of this genus 

 was taken b}' me I was unaware of its generic difference from 

 Stomoxys at the time of capture. 



HiEMATOBIA, Rob. Desv., 1830. 



Original description. — " Palpi elongati, ultra epistoma porrecti, 

 interdum apice dilat^i ; apud quasdam species, tarsi postici externe 

 serrati.' ' 



This genus was lirst split off from Stomoxys by Robineau 

 Desvoidy for those species in which the palpi are as long as the pro- 

 boscis, in contradistinction to calcitrans with its very short slender 

 palpi. The author added that the palpi are sometimes a little 

 dilated at the tip, and that in some species the hind tarsi (" tarses 

 posterieurs ' ' ) were serrated. He only included four species, all 

 from France. Of these, two [ferox and gcniculata) are s^'nonymous 

 with stimulans, Mg., and another {serrata) is synonymous with 

 irritans, L., a species for which Rondani erected the genus Z.y/'^^osm, 

 The remaining species, tibialis, still stands good as distinct and 

 remains in Hcematohia. 



From the more restricted point of view, the characters of 

 Hcematohia are: (i) the presence of minute but distinct (though 

 easily broken off) bristles at the base of both the ist and 3rd longitu- 

 dinal veins, this being the only genus in which these bristles 

 appear on the ist longitudinal vein ; (2) the arista being plumose 

 below as well as above ; (3) the i^alpi, which are practically as long 

 as the proboscis ; (4) the well-curved a])ical part of the 4th longitu- 

 dinal vein (as in Stomoxys, to which genus the present species bear 

 considerable resemblance in size and shai)e) ; (5) the broadly open 

 1st posterior cell. Ivcsscr characters may be gleaned from my table 

 of genera.
