equidistant from the middle, after the middle these two gradually apart 

 from the middle band and on the hind quarter sharply converging until 

 they each almost touch the middle band. 



Thorax rather short and roundish, black slightly dusted 

 with greyish. Dorsum much grey apically, with three inconspicuous 

 greyish median stripes of which the middle one is very narrow and 

 appears about the anterior part, while the others are about twice as 

 wide as the middle line (still narrow) and extends from the anterior margin 

 to the posterior margin sinuated at the suture ; the sides of the disc 

 more or less greyish white, so that there are very inconspicuous 

 though broad lateral stripes ; pubescence on the disc short, depressed, 

 yellowish, but with abundant somewhat long erect black bristly hairs 

 intermixed all over the surface, the yellowish pubescence growing up 

 much longer just above the wing-bases and on the outer margin of 

 the postalar callus and the black hairs becoming more numerous and 

 longer towards the sides ; humeri distinct greyish brown, clothed with 

 long shaggy greyish yellow hairs ; scutellum more greyish than the 

 thorax, clothed with scattered long black bristly hairs. Pleurae dark 

 yellowish grey, covered with a numerous long yellowish white pu- 

 bescence which is intermixed with similar but black hairs, the tuft of 

 long shaggy greyish yellow hairs on the prothorax, and on the upper- 

 hind margins of the meso-, meta- and ptero-pleurae, conspicuous. 



Wings about as long as the thorax and abdomen together, 

 somewhat greyish hyaline but brownish towards the costal margin, 

 with the veins at the apical margin of the basal cells, stem 

 and lower branch of the postical fork, and the base of the up^er branch 

 of the cubital fork (and sometimes with other veins), more or less 

 brownish, and with the stigma dark brown ; the upper branch of the 

 cubital fork with no recurrent veinlet or some trace ; first posterior cell 

 widely opened, and somewhat equal in width about the apical half; 

 anal cell closed long before the wing-margin ; discal cell moderate in 

 size, slightly longer than second posterior cell. Squamae in the alar
