Wings. — Ground colour^ rather dark grey, the extreme base 

 is tawny yellow, which colour suffuses more or less narrowly the 

 costa and most of the veins. The central portion of the wing is 

 blackish, becoming merged in the grey, posteriorly and towards 

 the tip. The 2nd posterior cell is equally wide at base and at 

 tip. Halteres dull reddish orange, stem darker. 



Described from a single 9 (?) in my collection, labelled " Key 

 Ins." Though I do not know on whose authority it is identified, 

 there is little doubt of it being Walker's species, with whose des- 

 cription it agrees, the only discrepancy being the reddish instead 

 of black 1st antennal joint. This species may prove synonymous 

 with satyruSj F., my specimen agreeing very closely with Van der 

 Wulp's description of that species, and fairly well with his plate,

? (?). Long. 15 mm. 



Head. — Frons rather narrow on vertex, widening until at 

 the upper part of the mouth-border it attains a width of nearh* 

 one-third that of the head : blackish grey with black bristly hair. 

 Ivower half of frons and the whole face round and below the an- 

 tennse (where it is somewhat prominent), rather bright ferru- 

 ginous red, with short black bristles. Ocelli very small, close 

 together, at some distance from the eyes and well below the vertex. 

 Antennae missing, except a single basal joint which is dark ferru- 

 ginous (nearly black) with thick black bristles. Proboscis black 

 with two apical, striated leaf-shaped ferruginous lamellae and a stiff, 

 pointed, central, spike-like organ. Mouth-border rather thickly- 

 beset with short black bristles. Eyes dark red with bronze reflec- 

 tions, facets very minute, uniform. Back of head dark grey with 

 a fringe of short bright yellow pubescence. 



Thorax. — Dorsum black, covered with sparse, very short, 

 yellow pubescence. On the front of the anterior border is a fringe 

 of thick orange-yellow bristly hair, with some shorter soft black 

 hair behind, which probabl}' spreads sparsel}'- over the whole dor- 

 sum, standing above the short yellow pubescence. On the pos- 

 terior border of the dorsum is a row of strong black bristles. On 

 the shoulders this black hair becomes very bristly, and is supple- 

 mented by three powerful long black spines just before the insertion 

 of the wings. Just below the humeral calli is a dense bunch of 

 long, fiery orange, erect, scaly bristles, behind which is a large tuft 

 of pale creamy orange, silky pubescence. The fiery orange bristles 

 extend forwards and below, joining the lower part of the anterior 

 fringe of similar colour. The posterior calli bear a similar bunch 

 of dense, similarly coloured bristles. From these calli four power- 

 ful long black spines spring, deflected backwards. The sides of 

 the thorax are cinereous grey, with long black bristles below the 

 base of the wings and a dense cluster of them around the fore coxae,
