is about 0"6 ni.iu., tuid it is very slender ; from this a.s lar out as the 

 eyes is the base of the maxilla, which, at first broad, soon narrows 

 and does not quite reach the end of wings. From the labrum to end 

 of appendages is about 4*0 m.m. The maxilla exceeds 3'5 m.m., and 

 where it ceases the 3rd tarsi appear and continue to occupy the 

 central position to the extremity. Outside them the second pair of 

 legs reach the extremity, and then the antenn.ne usually do so, but 

 are sometimes fractionally short. The tirst legs are about 3"3 m.m. 

 just outside the maxillasand a trifle shorter. Beginning at 0"6 m.m. 

 from the labrum and extending to 2'0 m.m., there is between the 

 maxilliB and first leg a spindle-shaped piece, divided by an oblique 

 joint, that is some portion of trochanter and femur of first leg. 

 Beneath the eye-])ortion of the face is a minute transverse piece 

 (the maxillary palpus), and below it, and of a width exactly equal to 

 the length of the palpus, is the first leg. The second leg touching, 

 or just failing to toucli, the palpus, ends here at a sharp angle between 

 first leg and antenna. The basal j^ortion of antenn;i; above other 

 appendages is very wide. The transverse markings of the antennte 

 are distinct, but the leg-covers, etc., are so finely sculptured by rows 

 of minute points that they may be called smooth. The labrum lias 

 strong transverse ridges. These are finer above, and at the upper 

 part of head are longitudinal. There is a rather strong dark point 

 just above outer angle of labrum, and above and within this a rather 

 strong bristle. 



The wings (and ajjpendages) reach nearly to hind margin of 4tli 

 segment. The nervures are well marked, and Poulton's line also along 

 the hind margin; the general surface is smooth, being very minutely 

 dotted. 



Close to the apex, just within Poulton's line, is a small, definite, 

 unmistakable bristle, and another at the anal angle similarly just 

 within Poulton's line. In some specimens I cannot discover the 

 latter, and in one specimen the former is wanting, not broken away. 

 This is a most unusual feature in pupse, perhaps because not looked 

 for. 



The prolhorax is devoid of bristles, but is very finely spiculated 

 at the margin of the spiracle, some of the spicules being fine and 

 hairlike. On the mesothorax the opposite side of the spii-acular open- 

 ing is also spiculated, but the spicules are very short and small, little 

 more than points ; they extend some distance back on to the outer 

 surface, and gradually merge into the points of the general surface, 

 which are here very minute, rounded and closely packed on the 

 wing-surface, but become large and separate on the dorsum, and have 

 a ringed appearance, being in fact centrally pitted. There are two 

 bristles on the mesothorax, about the middle, one near the middle
