three-fourth very much larger (about eight times) than those on the 

 lower part, and the large facets extend upwards to the vertex and 

 downwards beyond the junction of the eyes, while the small facets 

 extend in a narrow /.one all up along the back margin, the line of the 

 separation conspicuous and undulating and more obliquely downwards 

 than in Tabanus mandarinus^ but the vertical portion in the narrow 

 zone very inconspicuous ; in death pale reddish brown or greenish 

 yellow with darker median area which is usually transverse triangular, 

 and with a shimmer in a certain light. 



Thorax rather broader than in the female and the darker grey 

 stripes less evident and appearing in perfect specimens as faint narrow 

 stripes of brown or brownish yellow tomentum but the middle one 

 more conspicuously divided into two laterals by a fine but very con- 

 spicuous dark brown line nearly throughout the length ; the depressed 

 yellow pubescence less generally diffused and less obvious, and the erect 

 black hairs on the disc longer and more evident, which causes the 

 stripes to become less conspicuous ; the lateral stripes much more in- 

 conspicuous and the dividing stripe on the lower half hardly visible, 

 and the tufts on the upper wing-bases and on the posterior margin of 

 the postocular calli less conspicuous owing to the colour dull yellowish 

 grey ; pubescence on the pleurae longer and shaggier and more abund- 

 ant, and with more black hairs intermixed on the meso-pleurae ; 

 scutellum browner and with the black pubescence longer and more 

 abundant, but the yellow depressed one less and more inconspicuous. 



Wings, squamae, and halteres as in the female. 



Legs as in the female, but the pale pubescence usually light 

 yellowish without a shimmer and the black one almost always more 

 abundant and more obvious, and the colour being more dull especially 

 on the front tibiae which has no distinct whitish basal portion. 



Abdomen more conical, as long as the head and thorax (in- 

 cluding the scutellum) together ; dorsum more brownish, with the lateral 

 third or more usually reddish brown excepting the apical segments,
