as long as head, directed downwards ; palpi 1-jointed, long, 

 clavate, with long hairs. Antennae placed above middle line of 

 head, 3-joiuted ; 1st elongate, cylindrical, compressed at base; 

 2nd subglobular ; 3rd three times as long as first two together, 

 suddenly narrowing before one-fourth of its length and thence 

 gradually tapering to a point ; no style or arista.* Thorax 

 rectangular, considerably arched. Some weak dorso-central 

 bristles ; a humeral, post-humeral, larger and smaller notopleural, 

 supra-alar and postalar bristles present ; scutellum with two 

 bristles ; metapleura bare. Abdomen rather long and slender, 

 8-segmented ; the 7th and 8th segments in the male reduced, 

 covered by the genitaha, which latter are complex, somewhat 

 resembling those of Hilara. Abdomen in female rather thick at 

 apex, with only six obvious segments, the 7th being peculiarly 

 enlarged and the 8th concealed ; ovipositor small. Legs long 

 and slender ; fore coxae only slightly elongated ; fore femora 

 slightly thickened, with bristles below ; posterior tibiae with long 

 bristles and siuall apical spurs. Wings with auxiliary vein not 

 reaching margin ; 3rd vein forked ; discal cell present ; lower 

 branch of 5th vein recurrent, parallel with ])ind margin of 

 wing.

5 . Head blackish, eyes subcontiguous. Antennae with very 

 long cylindrical 1st joint, short large subglobular 2nd joint, and 

 very elongate conical 3rd joint, which has a very long thick 

 curved minutely pubescent style. Thorax dark brown, lighter at 

 the sides; scutellum and metanotum concolorous with dorsum. 

 Abdomen dark brown, but a little lighter than the thorax ; very 

 sparsely pubescent ; genitalia inconspicuous ; venter brownish 

 yellow. Legs long and slender, uniformly ])ale yellowish, except 

 the blacldsh tarsi. Pore coxae twice as long as the others, but 

 one-third the length of the fore femora ; all the femora approxi- 

 mately equal in length ; tibiae very little shorter than femora, 

 hind pair a little incrassated at the tips ; tarsi about as long as 

 tibiie, blackish. All the femora possess a few isolated long stifl' 

 hairs on the underside, and the middle femoi-a have one on the 

 front side near the tip ; all the tibiae with one such stiff hair on 

 outer side a little before the first third of the length, and a few 

 shorter ones on hinder side of middle tibiae, also a single one 



* Lundbeck describes the 3rd joint as taperiug into an arista, stating that a. 

 microscope fails to show any articulation. In such a case a simple joint only 

 must be recognised.
