colour, bat withal very transparent, dorsally more delicate, and, there- 

 fore, paler in tint. The wings and appendages are very smooth and 

 polished, and absolutely free from hairs, etc., the ventral aspect of the 

 abdomen is also polished and almost as hairless as the appendages, 

 but the whole dorsum is clothed somewhat densely with long pale 

 hairs. These look even denser than they really are by having entangled 

 amongst them a good share of larval hairs. The thickness of the pupa 

 is about 3-omm., and the length of the hairs is 1-Omm. to l-5mm. 

 They stand up erect on the thorax, but on the abdomen slope back- 

 wards, their distribution is somewhat equal, i.e., they are not collected 

 into tufts, etc. in any way. The anal spike, penlike in shape, is 

 0.9mm. long, smooth and polished ; towards the tip are, dorsally, half- 

 a-dozen minute pale brown hairs or spines and terminally a score of 

 rather longer curved hairs spread out somewhat like a fan. The 

 mouthparts present a labrum and two mandibles (?) as tliin lappets, and 

 below these a small rounded protuberance with a central suture, the 

 labium, and on either side of this, and rather behind than in front of 

 it, two rather smaller processes (the maxilhe). The antennjeare very 

 large and cover all the second legs except the tarsi ; the bases of the 

 1st legsare largely exposed owing to the comparative minuteness of the 

 maxilhe. 



The female pupa is not very dissimilar in size and outline to the 

 others of the genus. The length is about 14mm. to 15mm. The 

 width at each abdominal segment is —

The distance of these from anterior extremity is —

 It tapers regularly from the 5th abdominal segment. Ventrally, 

 the appendages just reach so as to touch the Brd abdominal segment, 

 o'Smm. from anterior extremity. The movable segments are the 5th 

 and Gth abdominal as in all other obtect pupa\ It may be noted that 

 the exposed ventral aspect of the 8rd and 4th abdominals, which is 

 covered in most pupa', is paler and more delicate than any other 

 part of the pupa and has not yet completely trained itself to be an 

 exposed portion of the pupa. On these and the two following segments 

 faint cicatrices of prolegs exist. The anal spike is almost exactly the 

 same as that of the 3 • The dorsum (lst-4th abdominal) shows the 

 sites of the Inrushes by paler, depressed, and less polished areas. The 

 whole dorsum carries pale hairs about 2nim. long, less dense than in the 

 3 pupa, apparently because spread over a larger area (from size of 

 pupa), and not from being fewer. They are erect on the forward seg- 

 ments, dellexed on the latter ; there are some shorter ones below the 

 spiracles. The whole surface is shining and polished, the spiracles 

 hardly marked as slightly darker pits. The head has a central 

 pronDuence, below which is the rounded labrum somewhat 

 prominent, with a delinite projection at either side (mandible '?), 

 below this is the labium, prominent and bilobed, but very short ; 

 the maxilla? are also very short, shorter than the labium, as small 

 triangles on either side of it ; the antennae are broad and short, 

 reaching half-way to end of the appendages, their tips slightly 

 overlaying the wings. There is a large triangle below the labium, 

 presenting the basal portions of 1st leg ; the 1st and 2nd legs are well
