inconspicuous, but on the front coxae, and about the outside of all the 

 femora longer and rather conspicuous ; there is a few short or long 

 black pubescence intermixed about the upper surfaces of almost all the 

 joints of the legs espesially on the tibiae conspicuous. 



Abdomen flat, very little longer than the head and thorax (in- 

 cluding the' scutellum) together, blackish grey with two somewhat 

 straight but gradually approach po.-teriorly to each other blackish 

 stripes and scarcelyany fulvus colouring. Dorsum with the hind corners 

 of the basal segment and the fore corners of the second segu'ient 

 obscurely fulvus, and the extreme sidemargins of all the segments also 

 obscurely fulvus ; densely clothed with short adpressed pale yellowish 

 white pubescence somewhat except on the two faint blackish stripes ; 

 the blackish stripes leave an intermediate fairly broad slightly grey 

 dorsal space, and the spaces between the blackish stripes and side- 

 margins are uniformly greyish (without any other blackish stripes), so 

 that (when viewed from behind) the abdomen does not show traces of 

 the usual Tabanoid three rows of grey flecks ; on the two blackish 

 stripes there is a fair amount of short sloping black bristly pubescence 

 which also appears on the space between the stripes especially on the 

 four posterior segments conspicuous so that a man could describe as 

 the abdoman has a broad blackish dorsal stripe, and also there is a 

 similar but very inconspicuous very few black pubescence on the middle 

 of the space between the black stripes and the sides so that the 

 abdomen does not show the traces of the black lateral stripes ; the 

 outer margins of the two black stripes are hardly dentate even though 

 the dark colour widens out slightly at the hindmargins of the second 

 and third segments ; the stripes become indistinct on the sixth and 

 seventh segments ; submarginal pubescence all greyish white but slightly 

 brownish, longer, and more outspread on the basal segment ; seventh 

 segment with fairly conspicuous rigid black bristly hairs, of which there 

 are traces on the sixth segment. Ventre ashy grey, but the three 

 posterior segments' yellowish, slightly shining, without any fulvus
