LAMPIDES BOETICUS. 351 



7th and 8th abdominal segments are remarkably modified ; here the 

 basal spines are much as in the others, but the central spine has a 

 very short stalk and a globular top, which is glassy- white and glisten- 

 ing, and with apparently an extremely minutely-spiculated surface ; 

 amongst these are a few with the same form, but with stem and globe 

 deep brown ; there are no ordinary spines, and a few show no central 

 spine, and might easily be taken for lenticles, some of which also 

 occur. Each segment is_^divided into two subsegments by a median 

 groove. The lenticles are not specially abundant near the spiracles, 

 but, in the incisions a little higher up, are so ; here they form rings 

 with marginal serrations, and some appear to stand up like cups ; the 

 serrations are semiobsolete spicules, and occur several together and 

 then a blank ; only rarely is there a complete regular set round the 

 margins. The prothoracic plate is obsolete, i.e., it cannot be defined, 

 unless these spots with slightly darker spines be its corners. The 

 lateral hairs are longer than the others, 0'5mm. in many cases, the 

 dorsal about 0-08mm. or less (Chapman). 



Vaeiation of larva. — The following notes on larvae from far 

 distant geographical districts may prove interesting : 



(1) South Africa : Bright green, paler on the undersurface ; a dark green 

 dorsal line ; beneath it, on each side, an indistinct line interrupted on each 

 segment, followed by a row of short, oblique, indistinct streaks of the same dark 

 green, and a pale green line just above the legs. Head small, shining reddish- 

 brown. Two-thirds of an inch in length (Trimen). 



(2) India : When full-grown seven-sixteenths of an inch in length, pale dull 

 green throughout, slightly shagreened, but not hairy, except slightly so at the sides; 

 the small retractile head smooth, pale ochreous-brown, shining ; a dorsal line of a 

 somewhat darker green than the ground, no other markings whatever, altogether a 

 very plain-looking creature. The constrictions at the segments shallow, the 

 spiracles black but inconspicuous, the usual extensile organs on the 12th segment 

 very short (Niceville). 



(3) Hawaiian Islands : Onisciform. Obscure olive-green, pretty thickly 

 sprinkled with short hairs (much the appearance of a bristly surface shaved); dorsal 

 and subdorsal lines and the region included obscurely rosy ; head testaceous, 

 bearing a black V-shaped mark, which points backwards ; the rosy markings vary 

 in intensity, as also the ground colour ; legs of the ground colour ; spiracles white 

 (Blackburn). 



(4) Europe : Elongated oval form, convex above, flat underneath, olive-green, 

 with somewhat reddish lozenge-shaped marks on the back. The vascular (dorsal) 

 line is broad and uninterrupted. No subdorsal. The stigmatal flange (line) bright 

 green, straight, uninterrupted. The stigmata are yellowish. There is a white line 

 running the whole length of the ventral surface, which surface is of a bright green. 

 The head small, black, very retractile, is almost entirely hidden under the first 

 segment. The true legs are brown, the prolegs are concolorous with the body. 

 The larva varies sometimes to bright green, and, but more rarely, to brown 

 (Milliere). [Milliere figures two larvae (Icon., i., pi. xxviii., figs. 1 (green), 2 (brown).] 



Godart describes the European larvae as "variegated with red on 

 the back," which leads Trimen to remark that Blackburn's Hawaiian 

 larvae, " described as of an ' obscure olive-green,' and as having the 

 ' dorsal and subdorsal lines and the region included obscurely rosy,' 

 accord in the latter character with Godart's description ; the head is 

 further described as ' testaceous, bearing a V-shaped mark which points 

 backward,' and the spiracles as white. It thus seems evident that the 

 larva varies considerably." One readily follows Trimen in this, by 

 reading his description of the African larva (supra). Anderson notes 

 (Victorian Butts., p. 84) that the Victorian larvae vary in colour, some 

 being very pale green, and others various shades of brown, but all have
