|HESPERIA MALViE. 237 



behind these, near the centre, two ochreous black-ringed lenticles, and 

 some smaller setae ; it is nearly cut in two by a fine black embedded 

 transverse line. In front of the spiracle is another lenticle, while 

 below, and anterior to the spiracle, is a large whitish tubercle bearing a 

 stout pointed seta directed forwards ; the 4th subsegment is rather 

 narrow. The meso- and metathorax have also four subsegments, the first 

 being very narrow, and the other three more of equal width. On the 

 mesothorax in the subdorsal area, is a lenticle, and just behind the 

 lenticle is a large pale membranous wart with a long fine hair (0-55mm.) 

 on its centre ; both wart and hair are remarkable and totally unlike any 

 other dermal warts or setae of the larva, except the two similar hairs on 

 the posterior margin of the 10th abdominal segment. Above the legs is 

 another lenticle. The metathorax is similar, but the peculiar hair and 

 wart above mentioned are both absent. On the 1st and 2nd abdominal 

 segments, which consist of five subsegments similar to the other 

 normal abdominal segments, there is a lenticle above the spiracle, and 

 another, below the spiracle, and a third (and sometimes a fourth) 

 beneath, in the position occupied by the legs in the thoracic segments. 

 The 3rd to 7th abdominal segments have each five subsegments, the 

 first very wide, the second half the width of the first, and the last 

 three much narrower, of nearly equal width ; the first subsegment bears 

 two lenticles about its centre, one on either side, and not far from the 

 mediodorsal line, just below tubercle i ; the 2nd subsegment bears the 

 rather oval rather raised spiracle, and an oval lenticle above the spiracle 

 anteriorly, another on the fold, and a fourth on the clasper. The 8th 

 abdominal segment has three equal subsegments, the very large spiracle is 

 on the 2nd subsegment ; the dorsal lenticles are wanting here, but those 

 immediately above and below the spiracle are present. The 9th abdominal 

 consists of two subsegments of nearly equal width ; the dorsal lenticles 

 are here present, and, owing to the smaller area of the 9th abdominal, 

 the lateral lenticles are crowded towards the dorsal so that there is a 

 transverse row of four lenticles ; the lenticle on the fold is also 

 present. . The 10th abdominal consists of the broad rounded anal nap. 

 Besides the usual secondary setae, which spring from the posterior 

 border of the anal flap, two long fine hairs may be observed, and one 

 or two setae which appear less stout than the majority. Below the 

 flap is a strong fold, and below this the claspers. There is a lenticle 

 on the claspers, and on their outer posterior wall a little above the 

 hooklet, is a large, conical, purple-black, horny wart. The pointed tip 

 is directed backwards and the wart is without any seta. Just below 

 the flap some of the teeth of the anal comb are visible. The anal 

 comb is wider and has more teeth (about eleven) than in the pen- 

 ultimate instar (Sich). Full fed : Length 18mm. (22mm. stretched); 

 colour a peculiar apple-green with overlaid yellow, especially where 

 intersegmental membrane overlaps, and with a reddish tone on the 

 thoracic segments ; head quite black (but with golden hairs) ; a darker 

 green dorsal line (really dorsal vessel). Rather nearer the spiracles 

 than to this is a band that suggests a darker tone than that above and 

 below it, and really is so, in so far that it has rather fewer yellow (?) skin- 

 points than the rest of the surface ; this band is bounded at each margin 

 by a very narrow and extremely tortuous yellow line ; these run from 

 skin-point to skin-point and are of much the same tint as they are. The 

 spiracles are orange. Below these is a marginal flange with comparatively
