CUPIDO MINIMUS. 121 



portionally large, 0*20mm. in length, out of 1-OOmm. The dorsal 

 hairs are long (0*1 6mm.), and the lateral 0-1 lmm. down to O05mm., 

 or even shorter. The hairs taken in series are i longest, ii more than 

 half as long, two supraspiracular hairs on each segment, and three 

 below the spiracle ; lower are two marginal hairs level, and two at the 

 base of prolegs. Of lenticles, there are two on each segment below i 

 and ii. The head has a few fine hairs. There are five ocelli in a 

 semicircle round a sixth central one, all of about the same size, and, 

 whilst the head is black, the mandibles are of a brown chitinous tint, 

 and have five teeth. There are four hairs along the front of the 

 clypeus, and three very fine ones on each side of the labrum. The 

 antenna? have two short broad joints, the second carrying a long hair, 

 and a small complicated joint. The prothorax carries a plate # 18mm. 

 across, diamond -shaped, with the angles very rounded, and the front 

 projecting more than the posterior edge. The plate has, on each side, 

 a long hair (015mm.) towards middle of posterior margin, and one rather 

 shorter near middle line, rather nearer front than posterior margin, and 

 a short one nearer middle line on front margin ; a little outside the 

 last is a large lenticle, and further .out and up on the disc three dots, one, 

 larger than the other two, is a small lenticle, the others probably 

 obsolete lenticles or hairs. Then there is, a little way in from the 

 external angle, the remarkable hair found in these Lycaenids, on a 

 peculiar base, and, being itself slender, and threadlike, and, unlike any 

 other hair on the larva, so fine is it that it is difficult to see, and may 

 be O08mm. long or more. In front of the plate are the usual three 

 hairs on each side, with one further back near the angle (all about 

 0'12mm. long); there are also two some way in front of the spiracle, 

 and two smaller lower down, and two very minute ones close to base 

 of legs. There is a large lenticle in front of spiracle. On the meso- 

 thorax and metathorax, the dorsal tubercles might be described as 

 duplicated. On the mesothorax there are two tubercles (hairs) to i, 

 one in front of the other, some little way apart ; the front one has a 

 lenticle just outside it, and then another long hair ; the posterior one 

 has a hair related to it just as ii is to i on the abdominal segments. 

 Lower down are four hairs corresponding with the three subspiracular 

 hairs of the abdominal segments ; the outer of the two front dorsal 

 hairs would, therefore, probably correspond with the supraspiracular of 

 the abdomen. These four subspiraculars of mesothorax are three in 

 an oblique row downwards and backwards, the fourth above, and 

 behind the third ; there are the two marginal hairs some little way 

 above the legs, the minute ones close to the leg belong rather to the 

 leg than to the ordinary tubercles. The metathorax has tubercles 

 i and ii much as on the abdominal segments, or as the posterior pair 

 on the mesothorax, yet the i corresponds, not with the posterior but, 

 with the front i of the mesothorax, in so far that, like it, it has outside 

 it first a lenticle and then a hair ; this hair on meso- and on meta- 

 thoracic segments, may correspond with the supraspiracular (iii ?) of 

 the abdominal segments, but it differs in being one long hair instead 

 of two very short ones. The four subspiracular, and two marginal 

 hairs are as on mesothorax. The abdominal segments have the hair 

 on i long, that on ii shorter ; two lenticles, a large anterior and upper 

 one, and a rather smaller one ; two short hairs, a front one about 

 0*06mm. long, and a posterior about half that length; the spiracle ; three
