 on the vertex, a large tuft of white hairs and hair-scales between the eyes pro- 

 jecting forward ; a row of black setse along the margins of eyes. 



Prothoracic lobes lateral, prominent, with blackish bristles. Mesonotum nar- 

 row, elongate, dark brown on the sides, pale brown and with pale blue-gray 

 pruinosity in a broad median stripe ; vestiture of numerous short pale yellowish 

 hairs and many very narrow white scales on anterior fourth of median stripe, 

 blackish hairs on the sides. Scutellum collar-like, grayish brown, with pale 

 brown marginal bristles. Postnotum elliptical, prominent, dark brown, nude. 

 Pleurae dark brown, coxse lighter, with a few fine hairs. 



Abdomen subcylindrical, depressed, truncate at tip, brownish black ; vestiture 

 of rather long, fine pale hairs arising from small black punctures. 



Wings (plate 41, figs. 13 and 18) moderate, hyaline; second marginal cell 

 longer than its petiole, second posterior cell distinctly shorter than its petiole ; 

 basal cross-vein distant about its own length from anterior cross-vein ; scales of 

 the veins narrowly lanceolate to broadly linear, dense, outstanding, black and 

 yellowish white, the black predominating, a large patch of white scales at outer 

 third of costa and involving first vein, a similar one just before wing-apex in- 

 volving also upper branch of second vein, a smaller one at extreme apex and on 

 the fringe, first vein with two long white patches on basal half, third vein with a 

 small white patch at base and a very long one at middle, fourth vein with the 

 stem mostly white scaled, fifth vein largely pale-scaled, a black spot near base and 

 another close to tip of lower fork, the upper fork black scaled, a spot toward 

 base and extreme base and apex white scaled, sixth vein with the basal half pale, 

 apical half black ; fringe with large pale spots at tips of all the veins. Halteres 

 whitish, with brown knobs. 



Legs long and slender; vestiture brownish black, tips of femora and tibisB 

 narrowly whitish. Claw formula, 0.0-0.0-0.0. 



Length : Body about 5 mm. ; wing 4.5 mm. 



Male. — Palpi as long as the proboscis; last two joints short, swollen, club- 

 shaped, with many long yellow silky hairs ; vestiture of last two joints yellowish 

 white, a black ring at the last articulation, long joint brown with a pale ring 

 near middle. Antennae rather stout, plumose ; last two joints long and slender, 

 rugose, black, pilose, the others short, pale, with black basal rings; hairs of 

 whorls long, dense, brown with silky luster. Coloration as in the female. 

 Abdomen elongate, depressed, brown above, the bases of the segments broadly 

 pale, each with a small median elongate shining brown basal spot; lateral 

 ciliation irregular, pale brown. Wings narrower than in the female, the stems 

 of the fork-cells longer, the vestiture more sparse. Claw formula, 3-0.0-0.0. 



Length : Body about 4.5 mm. ; wing 4 mm. 



Genitalia (plate 40, fig. 365) : Side-pieces about twice as long as wide, 

 conical, bearing a moderately stout spine beyond middle of inner margin; at 

 base two spines from a common base, two other spines arising from a detached 

 conical piece. Clasp filament as long as side-piece, slightly enlarged at base and 

 apex, with a small articulated terminal spine. IJnci slender, columnar, short, 

 rounded at tip. 



Larva, Stage IV. — Head rounded, elongate, bulging at sides, frontal portion 

 before antennae conieally produced; both pairs of dorsal head-hairs single but 

 numerously branched, in a line between antennae, a smaller hair at base of 

 antenna; two long approxjimate spines on front margin. Antennae sub- 

 cylindrical, slightly tapered, spined all over ; a single smooth hair toward base ; 

 two long terminal processes, a slender hair-tuft and a small digit at tip. Eyes 

 large, pointed. Mental plate small, with a median tooth and four on each side, 

 rather evenly spaced, the fourth small. Mandible quadrangular ; a basal row of 

 slender filaments, becoming short outwardly; two filaments and two branched 

 ones before tip; an outer row of cilia; five feathered filaments on outer margin; 

 dentition heavy, six teeth on a process, the third longest, a stout tooth below 

 followed by a small group of confluent spines ; a serrate filament within ; basal
