hairs. On the 1st and 2nd abdominals at a rather higher level, is a 

 longish plate with one hair, not so long as those above ; below this one 

 is a single-haired tubercle, and again another before the ventral line is 

 reached, three tubercles at about equal distances apart, below the long- 

 haired series. They are nearly in the middle line of the segment, the 

 lowest being a trifle posterior to the others. On the 1st thoracic is a 

 plate carrying a pair of median front bristles, one at each posterior corner 

 and two towards the anterior corner, i.e., four on either side. Below the 

 anterior angle of plate is a solitary hair, and another below and behind 

 this. Next a tubercle with two long hairs. On the 2nd and 3rd thoracic 

 i and ii seem to range with those on abdominal segments, iii has two 

 hairs, iv (?) has four hairs on 2nd, and five on 3rd. The 9th abdominal 

 segment has only one tubercle in place of i and ii, 10 has an anal plate 

 with four long hairs on each side, and a row of short simple hairs 

 along its hind margin. 



The anal prolegs appear to have ten large hooks arranged along 

 frds of a circle. The ventral prolegs are on distinct bosses, and have 

 columns or pedicels about 0-lmm. high, and 0-05mm. thick, and 

 slightly enlarged at the circlet of hooks. This circlet appears to possess 

 seven hooks, but to be without them on the outer side. The true legs 

 are of an usual appearance, with several very long bristles, especially 

 two at end of middle joint (tibia) ; the bristles are faintly spiculated. 

 Along with the claw is a long claw-shaped hair, placed above the claw 

 proper, and rather longer than it. This is not either of the two 

 shorter lateral straight hairs. The hairs on the legs are very faintly 

 spiculated. The long hairs of body (Fig, A., no. 2, x 130, Fig. A., no. 

 3, X 400) as well as being spiculated, have a slightly swollen extremity, 

 and this sometimes looks balloon-like, sometimes serrated or spiculated. 

 It does not seem to have any aperture, or is the balloon appearance due to 

 a delicate membrane that may very easily rupture and afi'ord the aperture 

 usually present in such hairs? The hairs have a double outline as of 

 a central tube. The general surface is covered by minute, apparently 

 very sharp, points. 



The ocelli present four in a curve, a fifth in the line of curve but 

 somewhat separated, and at the base of the antenna, and a sixth, near 

 the centre of the curve in which the others lie. The jaws have four 

 large teeth and a smaller one behind, and several very small ones in 

 front. On the anterior aspect the large teeth appear coarsely serrated. 

 The antenna has (1) a narrow basal ring, (2) a large joint rather 

 longer than broad, carrying a long bristle, two narrow processes 

 (thicker than bristles), and (3) a small joint, which again carries a 

 minute hair, two rounded processes, and (4) a minute joint with a fine 

 hair, and (5) a minute process. This description probably overlooks 

 several fine hairs and processes. If the basal ring and terminal process 

 be joints, then the antenna has five joints.
