individuals ; hind femora with a row of black bristles behind; all 

 tibiae with the usual rows of small black bristles ; hind femora with 

 a number of small black bristles on upperside at tip, giving the 

 appearance of the tip being blackish. Wings nearly clear, costal 

 and subcostal cell yellowish or dusky, the colour sometimes ex- 

 tending a little posteriorly, or in some specimens faintly or more 

 distinctly across the wing, even to the hind margin ; tip of wing 

 generally clear; 2nd longitudinal vein rather deeply looped 

 towards tip ; upper branch of 3rd vein with or without appendix ; 

 halteres mainly yellow.

 more specimens, mostly in good condition. 



Description of the -pupa-case. Pale yellowish, 10-segmented, the 

 1st with a brown prolongation, bearing six very strong blunt black 

 spines arranged two in an upper and four in a lower row ; two 

 similar but much smaller black spines in middle of underside of 

 segment ; 1st segment smooth and bare ; 2nd similar, but with 

 three or four very long filamentous pale yellow strong curved 

 hairs on each side ; 3rd segment bare, except for a row placed 

 just behind front margin, of very long, closely-placed, similar 

 curved hairs, which are almost spine-like at base, but taper 

 gi'adually so that the major portion is flexible; there are also 

 three very long yellowish similar bristly curved hairs (their bases 

 not spine-like) on each side of the segment. Dorsum of each 

 remaining segment with a transverse row, placed at about middle 

 of segment, of twelve or more strong bright brown hooks, about 

 three-fourths of the length of each being fixed to the surface, and 

 the tips curved upward and forward, evidently designed to hold 

 the pupa-case tightly, enabling the imago to draw itself free and 

 escape. These hooks are largest in the middle of the row, and 

 gradually diminish in size towards the sides, where are several 

 very long bristly hairs as on 3rd segment ; also between each two 

 hooks, its roots near the upturned portion (of the hooks), is a 

 similar rather shorter (though still actually very long) bristly 

 curved hair. On 4th, 5th, and 6th segments the hooks are very 

 large and strong, on the 7th considerably smaller, and on the next 

 three segments smaller still ; but the long bristly pale yellow 

 hairs are equally long on all the segments, except the 10th, on 

 which they are distinctly shorter. Tip of 10th segment formed
