with (liirker; male hypopygium with tlie apex of each 

 pleurite produced into a short blade ; inner pleural ap- 

 })eiulagc fceljly bifid at ajjex. 



Mall'. — Length 8G-!) nun. ; wing 8'5-9'4 mm. 



Rostrum and |)alpi dark brown. Autcniue black ; 16-seg- 

 mcnted, tlie formula l)eiiig 2 + 2 + 9+3; pectination of the 

 third flagellar si'gment inserted at a slightly dilTerent piano 

 from that of the basal two and the distal flagellar segments; 

 flagellar pectinations of moderate length. Head black, 

 sparsely brownish-grey pruinose anteriorly. 



^lesonotal prsescutum deep reddish brown with tliree in- 

 distinct darker brown stripes, the surface subshiny though 

 covered with a sparse microscopic pubescence; scutum brown, 

 the cephalic margin of the lobes l)lackened ; scutellura and 

 postnotum obscure yellowish brown, somewhat shiny. Pleura 

 with a very heavy silvery-white microscopic pubescence that 

 appears like a bloom ; propleura dark brown, sending a 

 narrow longitudinal stripe eaudad onto the niesepisternum ; 

 mesosternum dark; a narrow, longitudinal, brown line on 

 sides of mesosternum immediately dorsad of raid-coxse. 

 Ilalteres pale yellow. Legs with the coxae concolorous with 

 the pleura; trochanters brownish yellow; femora dark brown, 

 the bases more reddish, more extensive on the middle and 

 posterior ffuiora; tibiie and tarsi black, the posterior tibiaj 

 [)aler with black tips. Wings subhyaline, the base and cells 

 C and Sc brownish yellow; a very heavy dark brown pattern 

 covers approximately one-half the wing-surface, including 

 the following general areas : a large blotch at origin of Rs 

 not attaining vein J/; stigmal blotch sending a broad seam 

 along the cord, interrupted only in the centre of cell \st JV^; 

 wing-a()ex broadly darkened leaving pale areas only in the 

 mid-third of cell R.2, the second quarter of 71*3, and indistinct 

 j)ale blotches in the centres of cells R^, 2nd Mo, and M^, 

 the two latter more extensive; cell M is largely suffused 

 because of the unusually broad dark seams along veins 

 M, Cu, and Cwj; a large dusky suffusion before mid-length of 

 cell Cu and near the outer end of cell 1st A; other veins more 

 or less seamed with dusky; veins dark. Venation: cell 2nd 

 Ri very small, ?• being at tip of Ri and about three times its 

 length from the tip of R.^', petiole of cell M^ about three 

 times 7/t ; basal deflection of Cw^ near two-thirds the length 

 of the lower face of cell 1st A/j. The right wing of the type 

 shows a remarkable malformation of the veins, Rij^.^ bending 

 eaudad and fusing with the third section of 3/i+3 (petiole of 

 cell Ml) for almost the entire length of the latter. 



Abdominal tergites dark brown, the intermediate segments
