CALLOPHRYS KUBI. 107 



on each side, a dorsal group (i + ii) of seven or eight very large 

 (0-42mm.) hairs, with smaller ones, making about fifteen ; below this, are 

 six or eight hairs, above and behind spiracle, and not widely separated 

 from those above ; below the spiracle, a group of twelve or fourteen hairs 

 (about 0-3mm. long) and two groups of paler hairs follow; the groups 

 are even less distinguishable on the latter segments. Between the 

 dorsal warts (they are too large for warts and are rather groups of 

 independent hairs), is, on each segment, a lenticle (never two), some- 

 times median, sometimes on one side, sometimes the other; group i + ii 

 has a lenticle on its anterior aspect ; there is another on front of segment, 

 between this and the supraspiracular group, two just above spiracle, 

 and one or two lower. The prolegs have five hooks on each pad. The 

 hairs are finely spiculated as in first skin. Their bases deserve a word, 

 for they are conical, but with curved outline ; reversing them, and 

 regarding the hair as a stalk, they are like a salver-shaped flower, a 

 convolvulus or petunia, the margin being divided, by lines or sutures 

 running up, into seven or eight divisions, the margin of each division 

 convex, like a separate petal. The skin-surface is finely reticulated. 

 It is to be noted that the hairs, though so much more numerous, 

 are not only relatively, but actually, shorter than in first instar. 

 Third instar : 9mm. long. The most notable feature, which existed 

 somewhat, but only slightly, before, is that the mesothorax, as it were, 

 forms a deep fold behind and above prothorax, somewhat overlapping 

 it ; the appearance is as if the mesothorax formed the front of the 

 larva, and the prothorax was a small appendix in front and below; 

 this smallness and thinness of the prothorax must facilitate thrusting 

 the head into flowers, which is still its habit, though it eats them 

 away now more completely. The prothoracic plate is small, brown, 

 with median pale line or suture. The lateral line may still claim to 

 be yellow, and is narrow and rather well-defined, and occupies the 

 prominent margin of the lateral flange. The general colour of the 

 larva is green, most marked on the site of the old subdorsal white mark 

 or band. The spiracles are also on a very green line; above and below 

 these are reddish shades ; the double dorsal band is also fairly marked, 

 of a dull reddish or pale brown ; these colours vary much according to 

 the angle of view, being apparently some distance beneath the cuticle, 

 as is so common in Lye£enid larva?. The larva is 2-7mm. wide, and about 

 2-5mm. high, and narrower at either end, but the mesothorax and 8th 

 abdominal segment are still very wide, and the greatest narrowing is 

 done forwards in the rounded prothorax, and behind in the last three 

 segments, which are very short, and almost without trace of incisions. 

 The head is nearly black, polished ; the labrum and antennas nearly 

 white. The dorsal ridges are wide and very rounded, so that they can 

 hardly be called ridges ; the incisions are deep, and each segment 

 presents a large dorsal boss, a fairly pronounced lateral boss, 

 and, in addition to these two (the dorsal and lateral flanges), there 

 is, above the spiracles and between the other two, a smaller 

 boss. Each of these bosses possesses a number of nearly black 

 hairs that radiate from it as separate sets (the larva moulted into third 

 instar May 7th, and was described May 9th, 1906). The colouring of the 

 larva was rather brilliant in the second instar ; most are now green, but 

 with the yellow of second instar, as a paler green, looking like a boss 

 on the side of the dorsum of each segment, stretching downwards
