RURALIS BETtfLJE. 29l 



hair (vi ?) towards the front portion of the segment, with two hairs 

 nearer proleg (vii) (March 25th). Four days later has fed up a good 

 deal, and is now more easily examined. The head, at first as wide as, 

 or wider than, the body, is now half the width of the prothorax, 

 into which it can be retracted, and the "slopes" are now long and 

 steep and contrast with the narrow level back, which were before 

 more in one rounded surface. The colour is now green, with whitish 

 patches round tubercles i and ii, and darker in the two slightly oblique 

 hollows on the slope, the beginnings of oblique markings, so usual in 

 Lycgenids. The general surface is covered with dark skin-points, which 

 are wanting between i and ii and on the white patch surrounding them. 

 The note concerning the tubercles, etc., on the abdominal segment, 

 given earlier, is correct, except that there is a lenticle above the solitary 

 hair noted on the second flange. There is also a large lenticle on the 

 front border of the segment just above the flange and below and in 

 front of the spiracle on the 1st and 2nd, and on the 7th and 8th, 

 abdominal segments, but wanting on the intermediate ones. On the 

 prothorax the plate has a median suture ; on each side towards the 

 front is a large lenticle. There are also five hairs, two in front — if 

 there were a third at the outer angle there would be three equally 

 spaced ; the largest hair is a little behind the middle, the two others 

 are one inside and in front of this, another towards the outer back 

 margin. There are three long hairs in a row below and in front of 

 plate and two others below them. These are almost directly in front 

 of the spiracle. Some way below the spiracle is a large lenticle with 

 a small hair in front of it, and lower two small hairs (at base of legs). 

 On the 2nd and 3rd thoracic segments the arrangement is almost as 

 on the abdominal segments. There is, on the "slope," only the single 

 lenticle, and a hair where the lenticle is on the 1st and 2nd abdominals, 

 at the front corner above the flange. The flange has three hairs, 

 without the fourth one below, and there follow only two hairs at the 

 bases of the true legs. The prolegs have, at the end of the prop 

 outside, a row of black hooks, then the usual central prolonged soft 

 pads and the front and back pads, each with two (or three '?) hooks. 

 On the 8th abdominal segment there is a dorsal hair (i?), and then 

 nothing to the spiracle. On the 7th abdominal segment, one lenticle 

 only between ii and the spiracle, i.e., the second minute lenticle 

 above the spiracle is wanting. On the 7th, 8th, 9th and 10th 

 abdominal segments the flange is continuous, with no segmental 

 divisions, and carries ten hairs (on each side) in an upper row and about 

 five in a lower, with other and smaller hairs behind. The anal plate 

 has dark markings, but no hairs or lenticles. [See plate vi., fig. 3, for 

 a clearer view of the disposition of hairs, lenticles, etc. It is slightly 

 diagrammatic, but is believed to be all but, if not quite, accurate as 

 to position, etc., of hairs and lenticles. The skin-points are not 

 shown on any of the sketches (pi. vi., figs. 1-4). They are present in the 

 first instar in all the species, but not after.] In the first instar, tubercles 

 i and ii carry, as usual, a long and a short hair, that on i more upright, 

 and together forming a crest down the dorsum. They arise from a 

 joint base, at least skin-points are absent between them. Above the 

 spiracles (abdominal) is a minute lenticle, with a more minute spot 

 just below it, probably really a second lenticle. Below the spiracle, 

 on the flange, are four hairs, a median the longest, one at same level
