antero-dorsal surface, the apical three or four much the strongest, 

 antero-ventral row consisting of about seven equally strong, equi- 

 distant on the basal half and about fifteen on apical half, the first two 

 of which are strong and widely placed and the next thirteen of which 

 rapidly decrease in size and become closer placed till they form a 

 comb of short setulae on the thin apical third of femora, postero-ven- 

 tral surface with a similar row, postero-dorsal surface with a row of 

 bristles which increase in size towards the apex, mid tibiae gradually 

 thickened on apical two-thirds, pubescence sparse and short, especi- 

 ally on basal half of ventral surface, one antero-dorsal bristle at 

 apical fourth and one at apical third and postero-dorsal surface, as 

 well as one at very close to apex on nearly the dorsal surface and the 

 end spurs, hind femora with a row of bristles on apical half of the 

 antero- and postero-dorsal surfaces which increase rapidly in size 

 on apical third, the last three being very strong, as well as three or 

 four strong bristles on the antero-dorsal surface from apical third 

 to tip, hind tibiae with a very long bristle at near middle and another 

 at near tip on dorsal surface, a series of four, the middle two of 

 which are strongest, on antero-dorsal surface and a series of four 

 shorter bristles on the antero- and postero-ventral surfaces ; wings 

 grayish, inner cross-vein almost directly below the end of first vein, 

 third and fourth veins distinctly convergent at wing margin, large 

 cross-vein slightly bent, barely its own length from inner cross-vein 

 and less than one-fourth the distance from inner cross-vein to wing 

 margin ; under scale of calyptra distinctly longer than upper ; hal- 

 teres yellow. 



Female. — In color and size similar to the male. Frontal stripe 

 nearly one-third as wide as head, central stripe " matt "-black, bifid 

 posteriorly, eye-margins silvery gray, frontal stripe slightly nar- 

 rowed towards vertex, antennae colored as in male, but the arista 

 hardly longer than antennae ; abdomen not so pale as in male and the 

 dorsal stripe interrupted on posterior margins of segments ; legs 

 colored as in male but the hind tibiae are paler, the mid tibiae have 

 two ventral bristles at apical third, the dorsal bristling being as in 

 male, the hind femora have two very distinct bristles at near tip 

 on antero-ventral surface, a row of short bristles and two or three 

 long ones on antero-dorsal surface, the latter at near tip, and the 

 hind tibiae have the two dorsal bristles as in male, as well as three 

 or four on the antero-dorsal and antero-ventral surfaces from basal 

 third to apical fourth ; the outer cross-vein in wing is nearer to wing 

 margin than in male. Length 2-3 mm.
