dozen medium-sized setulse inside the hind edge from which they are sep- 

 arated by a more distinct groove than usual, one long and one short spur. 

 Hind femora with a few curved bristly hairs below at the base. Wings rather 

 long and narrow, the costa reaching barely beyond the middle of the wing, 

 its bristles rather long, slender and closely placed ; first division equal to or 

 scarcely exceeding the second ; third one-third as long as the second, the fur- 

 cation of the third vein acute ; fourth vein curved only at the base ; fifth vein 

 nearly straight, sixth slightly sinuate, seventh distinct. Halteres piceous, 

 yellowish at the base of the knob. 



One male from Goenceng Gedeh, Java, March, 191 1 (Jacobson). 

 This is related to the British A. bcckeri Wood, from which it dif- 

 fers by the small hypopygium, shorter costal bristles and higher front. 



Aphiochseta atrita new species. 



Male. — Length 2 mm. Black ; legs piceous, the front pair fuscous ; wings 

 hyaline, veins dark fuscous ; palpi pale yellow. Front abotit as high as broad, 

 its bristles strong; ocellar tubercle and median frontal groove present; four 

 post-antennal bristles, the lower ones half the size of the upper and two-thirds 

 as far apart ; inner bristles of next row barely above the upper post-antennals 

 and midway between them and the eye-margin ; outer bristles of this row 

 close to the eye-margin and considerably above the inner ones ; row above 

 strongly curved downward medially. Antennas rather large ; arista pubescent, 

 one-half longer than the height of the front. Palpi of moderate size, strongly 

 bristly below. Cheeks each with two large, stout bristles directed downwards 

 and a series of much smaller ones extending toward the base of the antennae. 

 Mesonotum strongly convex, subshining, its lateral bristles short, except for 

 one very long one a short distance in front of the hind angle; one pair of dis- 

 tinct dorsocentral bristles. Scutellum twice as broad as long, not strongly 

 curved behind, with one pair of strong bristles and a weak hair anterior to 

 each of these. Propleura bare except for three downwardly directed bristles 

 at the lower margin and one upwardly directed one just below the spiracle. 

 Mesopleura bare, shining below and slightly roughened above. Abdomen bare 

 except for a few bristles on the last two segments and a very few short ones 

 evenly distributed along the sides ; none of the segments elongated. Hypo- 

 pygium very small, sparsely clothed with fine hairs ; lamella dark, paler at tip. 

 Legs long, but rather stout; front tibiae without setulas, their tarsi slender; 

 middle tibise with no distinct setulae and one long spur; hind tibiae with a few 

 weak and rather short setulae inside the hind margin on the apical two thirds, 

 with one moderate and one short spur; hind femora with a few weak curved 

 bristly hairs below near the base. Wings moderately long and narrow ; costa 

 just attaining the middle of the wing, its bristles of medium length and sparsely 

 placed apically although closer together near the base ; first section of costa 

 barely longer than the second and third together; second twice as long as the 

 third ; fourth vein weakly curved at the base, almost straight beyond ; fifth
