CALLOPHRYS RUBI. 105 



and a large lenticle ; there are thus four along the front evenly spaced, 

 these are the shorter of the longer ones, viz., about 0'22rum. The 

 large lenticle is between and behind the pair of either side. One 

 of the long hairs (045mm.) is close behind the lenticle, and the other 

 further back and outward, the short hair (Olmm. or less) is close to 

 the outer angle. There are three long hairs in a line in front of the 

 spiracle, but well above ; another below these, just in front of, and in 

 line with, the spiracle, and two short hairs at the base of the leg. The 

 mesothorax, like all the other segments to the 7th abdominal, carries 

 i and ii on each side on a conjoined base (and about 2-2mm. from 

 opposite pair) ; the hairs about 0*6mm. long. In front of these, and 

 nearer the middle line, is a short hair (0-2mm.). This seems to be 

 the same hair that, on all the other segments, is in front of, and 

 exterior to i and ii ; then follows a group of four hairs set four square, 

 apparently representing iii ; then a shorter hair and a shorter one still 

 below it, apparently iv and v ; then the two fine ones at base of leg. 

 The metathorax has i and ii (0-7mm.) with the accessory in front and 

 outside (0-22mru.) ; on one side, a second shorter hair is outside this in 

 one specimen ; below this is a very large lenticle with minute hair above 

 it, in range with the pair of lenticles on following segment ; then two 

 hairs in line of iii, ranging with two similar hairs on all the following 

 segments to the 6th abdominal ; then four hairs ranging with the 

 similar four, and representing iv |v on the following segments, and 

 then the two fine ones at base of leg. With regard to i + ii, they are 

 identical on the mesothorax, the metathorax, and the abdominal 

 segments 1 to 6 ; here, these tubercles are conjoined, and carry 

 long flowing hairs (0-6mm.), the accessory in front and outside 

 (012rum.), then there are two lenticles smaller than the one on meta- 

 thorax, their rims are nearly as deep as high, so that they look very 

 like hair-bases ; at this site many larvae have a surface puckering or 

 depression. Above the spiracle, iii is double, and carries two hairs on 

 separate bases, the front one the upper and longer (0'23mm.). Then 

 comes the spiracle, followed by four hairs, nearly four square, but the 

 lower posterior one is rather lower than this would admit. Below this 

 are two hairs, on a level with each other, on the segments with prolegs, 

 but one above the other on the other segments, and then (vii) carrying 

 two small hairs on base of proleg; on the other segments there is only 

 one minute hair. On the 7th abdominal, i (?) is absent ; ii from 

 each side, with the accessory, are combined on one base in middle of 

 segment, together with a large lenticle that may be base of ii ; then 

 follows another lenticle, two hairs (iii), then spiracle, then below it 

 four hairs (as usual), a lenticle, and one hair. Abdominal segments 

 8, 9, and 10 cannot easily be distinguished. Above the spiracle of the 

 8th abdominal, and between the 7th abdominal and anal plate, are 

 four lenticles placed four square (two on each side) ; no hairs ; below 

 the spiracle is a group of five hairs with their bases very close together, a 

 lenticle, and two hairs. The anal plate is a shield-shaped scutcheon, 

 and behind and beside it are three hairs, each with another approximately 

 beneath it. Behind these the skin-points are finely acuminate. The 

 true legs are ochreous or brown ; of the prolegs, each pad has two 

 hooks. The skin-surface is beautifully netted with very fine lines, 

 and, at each intersection, is a little 4-, 5-, or 6-rayed star, the rays 

 having no relation to the lines of netting. I irst instar (f ullgrown) :
