2. TABANUS 407 



tinned clearly to the hindmargin but inclined to join tlie next two stripes 

 soon after the suture, after which these two stripes continue rather more 

 vaguely and spread out all along the hindmargin, and the outer stripes do not 

 quite extend to this hindmargin but bend inwards and end m a pomt ; prsealar 

 calli obscurely brownish red. Pubescence composed of fairly numerous but 

 not conspicuous erect black hairs all over except on the front part where 

 they are shorter and denser though pale, and in good specimens numerous 

 sloping or depressed thin greyish yellow hairs occur intermixed among the 

 erect black hairs but are easily abraded and leave only traces of their 

 existence : pleurae with all brownish yellow pubescence which is dense and 

 woolly except on the lower parts. Scutellum with similar but slightly longer 

 erect black hairs all over the disc, but with a fringe of equally long fine pale 



hairs about the margin. , , , . , • ■, • u 



Abdomen longish, flat conical, and greyish black with conspicuous brownish 

 ochreous (but not reddish) and grey markings on the second and third segments 

 besides less conspicuous markings on the other segments ; the point of the 

 grey middle triangle on the second segment extended to the foremargm 

 but on the subsequent segments not reaching much above the middle, and 

 there is a rather long yellow hindmarginal fringe on the second and sub- 

 sequent segments, and a patch of similar pubescence at the midclle of the 

 hindmargin of the basal segment ; base and the basal corners broadly ot the 

 basal segment grey, and conspicuous sloping grey side-flecks of rather unde- 

 fined shape and marsin occur on the second, third, and fourth segments, but do 

 not as grey flecks exfend to the foremargins and not widely to the hmdmargins, 

 but the whole front corners (varying in amount) of the second segment are 

 brownish ochreous (but not so red as in T. glamiis) and often amalgamate 

 with the grey flecks and then extend broadly to the hindmargin, leaving 

 however a lateral black patch at each hind corner of the segment which 

 extends obscurely to the hindmargin • third segment sometimes \yith con- 

 siderable brownish ochreous coloring which is not so conspicuous or defined as 

 that on the second segment, and the blackish side patch much larger though 

 also rather indefinite ; fourth segment sometimes with a trace of similar 

 ferruginous coloring over about the space occupied by the grey side-tiecks • 

 absolute sidemargins of the second to sixth segments distinctly brownish 

 ochreous. Pubescence depressed and yellow on the ferruginous and grey parts 

 and occurring as a fairly continuous fringe on the hmdmargins of the second, 

 third, and fourth segments, though black between the middle and the side- 

 flecks and more conspicuous on the outer thirds of all the hmdmargins; 

 sidemarginal pubescence rather longer and fairly conspicuous, yellow on the 

 five basal segments but considerably black on the sixth and seventh segments, 

 while some black hairs appear to be intermixed near the hmd corners ot the 

 basal segment and on the black patch on the second segment, and there are 

 traces of black hairs on the third and fourth segments but close examina- 

 tion shows that they are not on the actual sidemargins ; pubescence on tlie 

 black parts short depressed and black, but more erect on the disc ot the two 

 basal segments. Belly blackish grey down the sides and on a more or less 

 interrupted middle line but usually dull ferruginous between ; hmdmargins 

 narrowly and inconspicuously lighter grey; sixth and seventh segments 

 blackish and with the usual longer black bristly hairs numerous and 

 fairly conspicuous. Genitalia small but margined with deep orange color- 

 ing beneath the seventh segment. .■ t 

 Legs dull greyish black, but dull reddish orange on the extreme tip ot 

 the femora, nearly the basal half of the front tibiae, all the middle tibiae 

 except the tip, the extreme base of the middle tarsi, and either the extreme 

 base of the hind tibiaj or sometimes all the hmd tibiae except just the tip; 

 front tarsi deep black. Pubescence on the front coxae long, greyish white, and 

 rather abundant ; on the front femora scattered and long, greyish yellow 

 about the base but black about the tip, with the underside conspicuously 

 shining black and bare (for the reception of the folded tibne) and witli a 

 dense row of minute black bristles on the anterior margin of the bare space ; 

 on the middle femora shorter and less conspicuous and dull pale yellowisli ; 

 on the hind femora dense, longer, and greyish yellow antero-ventrally ; 

 tibiie with short depressed bristles which are mainly yellowish on the under-
