196 Records of the Indian Mitseiun. [Vox.. IV^ 



The tj'pe of Tabanus orieniis is from Nepal, the types of 

 Tabanus consocius and perlinca from India, Saunders coll. 



In Brit. Mus. coll. specimens from N. W. Province ; Naini Tal 

 and Thandiani, Himalayas ; N. India ; W. Bhutan. 



In Indian Mus. coll from Mussoorie, N. India, about 7,000 

 feet; in Brunetti coll. from Naini Tal, Kumaon, 6 — 7,000 feet 

 (Lloyd); Minda, Nepal, and from Dongagali, Murree district, W. 

 Himala^^as. It appears to be a Northern Indian species in distri- 

 bution. 



A medium-sized species with almost clear wings and a reddish 

 3^ellow abdomen which, when not denuded, is clothed with yellowish 

 or whitish triangular median spots and segmentations. Forehead 

 moderately broad with a large callus, its linear extension almost the 

 same width as itself. Legs black, the tibiae ^-ellowish. Eyes with 

 three bands. Length 15 — 17 mm. 



Face covered with 3'ellowish or greyish tomentum. Beard and 

 pubescence of face yellowish white. Palpi long, slender, only slightly 

 stouter at base, ending in a rather obtuse apex, with scanty black 

 pubescence and few white hairs below. Antennae red, often darker 

 at apex, the first two joints and the apex of tooth with black hairs. 

 Forehead slightly narrower anteriorly, about five times as long as 

 it is wide, covered with yellowish or white tomentum and with 

 some black pubescence, the frontal callus blackish or reddish 

 brown, oblong, not reaching the eyes, its linear extension quite two- 

 thirds its own width, though sometimes narrower at its lower end 

 where it joins the callus. Eyes with three bands. Thorax black, 

 when undenuded covered with yellowish tomentum and with 

 appressed pale yellow hairs, the pubescence black, no stripes 

 visible ; the hairs at sides black : breast covered with yellowish 

 white tomentum and with white pubescence ; scutellum same as 

 thorax. Abdomen reddish yellow on the three first segments with 

 the exception of a large black median spot on the second and third, 

 very distinct when insect is denuded, the fourth segment is very 

 largely the same colour but often blackish on its posterior border, 

 the remaining segments appear blackish but in the fresh insect the 

 posterior segments are widely yellow, on all the segments appear 

 yellow-haired triangular spots, and the segmentations are all 3^ellow 

 tomentose with yellow pubescence, elsewhere on the dorsum the 

 pubescence is black, under side reddish yellow, only the extreme 

 apex black, with 3'ellow short pubescence. In some specimens the 

 abdomen is darker with blackish markings on each segment, but 

 the large callus of forehead distinguishes the species without diffi- 

 culty. Legs black, the tibiae a rather transparent yellow, the fore 

 pair black at the apex, the femora with 3-ellowish white tomentum 

 and pubescence, the tibiae and tarsi with chiefly black pubescence. 

 Wings usually clear, sometimes slightly tinged, usually without an 

 appendix. The ej^es in life are described as greenish with three 

 violet-green bands. 



Tabanus orientalis, Wied., Auss. Zweifl. Ins., i, p. 145, from E. 

 India, must be very nearly allied to this species, but Wiedemann
