second posterior cell, also very slightly narrower, its base nearer 
the apex of the wing, its stem nearly equal to its length; stem 
of the second posterior about two-thirds the length of the cell ; 
posterior cross-vein about its own length distant from the mid. 
Halteres with ochraceous stem and fuscous knob. 
Length.—4 mm.

1, Mid ungues of & D. obturbans, Walker ; 2, of D. fusca, n. sp. ; 3, g palp 
of D. panalectros, Giles; 4, of D. fusea, n. sp. 
6. Head, thorax and abdomen as in the 9 ; palpi black, similar 
to D. obturbans, but the apical joint not as long as the penultimate 
joint ; fore ungues unequal, both uniserrated ; mid more or less 
equal, one toothed and of usual form, the other contorted and 
apparently simple; posterior tibiae longer than the metatarsi. 
Length.—4 mm. 
Habitat.—Kuala Lumpur (Dr. Durbam). 
Observations.—Closely related to obturbans and panalectros, but 
smaller, and the ¢ has the apical palpal joint shorter than the 
penultimate joint ; in panalectros the two joints are about equal ; 
in obturbans, the apical slightly longer, but especially differs in 
having the curious mid ungues shown at fig. 75. 
The larvae of this species sent by Dr. Durham were taken in 
a tub. It resembles very closely the larva of panalectros, and I 
have not had enough perfect material to work it out, but I could 
detect one constant difference, namely, in the number of spines at 
the base of the last segment, which are six (vide Plate X VI1.), 
not ten to twelve (probably twelve always), as in A. panalectros. 
The hair tufts on the sides of the first abdominal segments are 
composed of two bristles only, not several as seen in A. panalectros.
