yellow with a broad, black, median stripe ^vliicli splits 

 beliiiid into two divergent arms enclosing a yellowish tri- 

 angular area between them, this lying immediately before 

 the suture ; lateral stripes broad, dark brown ; scutum with 

 the lobes brown : scutellum obscure yellowish ; postnotum 

 pale yellowish brown, the sides darker. Pleura pale brownish 

 yellow with indications of darker brown clouds on the 

 mesepisterna. Halteres moderately long and slender, dark 

 brown, the extreme base paler. Legs with the coxre pale 

 brownish yellow; trochanters dull yellow; in the male 

 allotype the femora are brown with a single yellow ring 

 before the broad brown apex, a narrow yellow median area 

 being barely indicated ; in the females, however, the femora 

 are pale brown, more yellow on the outer half, with a narrow 

 blackish postraedial ring and a slightly narrower and paler 

 subapical ring, the tip broadly yellow ; tibiie black, the 

 extreme bases a little paler ; tarsi black. Wings pale 

 brown with darker brown marks along the costal region, the 

 first at the arculus, the third at the origin of i?s, the fourth 

 at the tip of Sci ; stigma rectangular, dark brown ; cord 

 and outer end of cell 1^^ Mo narrowly seamed with brown ; 

 remainder of the wing-surface variegated with yellowish 

 spots and blotches, these occurring in all the cells, the more 

 conspicuous being as follows: before and beyond the stigma ; 

 before the wing-tip in cells 2nd Hi and R^ before the cord, 

 in cell 1st iV/g, in the bases and before the tips of cells 

 2n(l M2 and M^, in cell Cu before the basal deflection of C/Mj, 

 near the end of Cu^ Ist A, and 2nd A; veins dark brown ; 

 a[)ical cells of the wing with macrotrichia, these including 

 the stigma, cell 2nd R^, the outer half of i?3 and R^, all 

 but the base of 2nd Mo, M3, and the extreme tip of Cu^. 

 Venation : Sc long, ending about opposite mid-length of Rs, 

 Sc, at the extreme tip of ASc^and more than twice its length; 

 jR>- strongly anguluted at origin ; r at the tip of R^ ; veins 

 7i?2+3 and Ri^r, running parallel to one another, so cell 2nd Ri 

 is very wide at the wing-maroin ; cell 1st Mo closed, about 

 as long as vein Cu^ beyond it; basal deflection of Cmj before 

 the fork of M, this distance longer than 7'-in. 



Abdomen short in both sexes ; tergites pale brown, tho 

 sternites yellowish ; a blackish spot at the posterior lateral 

 angles of the sternites. Male hypopygium with the pleurites 

 rather small, on the proximal face with a large fleshy 

 appendage, which is provided with long coarse hairs ; j)leur:il 

 appendages small. Gonapophyses appearing as flattened 

 plates, each terminating in an acute blackened point that is 

 directed caudad and slightly latcrad. Ovipositor with the
