THE LARVA OF PHIBALAPTEEYX LAPIDATA. 209 



pale baud begins the warmer, 'redder, but paler, ventral area. It 

 is followed by two darker (reddish) fine lines, then after a broader pale 

 baud, a dark band, and a very fine, not quite so dark, medio-ventral 

 line. 



The subsegmentation is elaborate and complicated, dorsally are 

 seven subsegments (2nd to 4th abdominal segments), five small, and 

 two larger, the latter again subdivided each into two, if these be 

 reckoned separately, then nine nearly equal, subsegments. The large 

 ones are the first and last. The first large one carries tubercles i and iii ; 

 the second and third, united laterally into one, bear the spiracle ; the fourth 

 has a tubercle (iv ?) behind and below spiracle ; the fifth carries ii. Below, 

 and in front of, the spiracle, is a tubercle on the first subsegment, which 

 here broadens obliquely backwards to quite below spiracle ; lower, on 

 two bosses, the anterior of which combines subsegments one, two, three, 

 and four, and the posterior five, six, and seven, are two hairs ; below 

 the front of these is a hair on the darker band most ventral (except the 

 medio-ventral line), and below the other are two hairs, one on each of 

 the pale bands below, and one therefore dorsal, the other ventral, to 

 the hair in front of them just mentioned. The hairs are of fairly 

 uniform length, about 0-25mm. to 0-8mni. long, dark brown, stiff' and 

 smooth, on the conspicuous black bases already referred to. There are 

 other very minute hairs or hair-points, one, for example, in front of i, 

 and one below iii. Behind, just above, prolegs, is a slight dark pro- 

 jection, but no points. The head is rounded, smooth (at least its 

 granulations are very fine), ochreous, with brownish marblings, four 

 eyespots in a semicircle, a hair looks like a fifth, and a central one ; a 

 good many hairs, rather paler than those on the bodj'. 



The prothorax has two transverse rows of four hairs (tAvo on each 

 side) apparently on a prothoracic plate, and one at each end, with a 

 smaller companion below it (between the two rows), just beyond plate, 

 and not far ahnre spiracles. The subsegmentation makes it difficult to 

 define margins of the meso- and metathorax, but, on a forward subseg- 

 ment of each, are, in a transverse row, six hairs (three on each side) down 

 to spiracular level, the two most dorsal in the two most dorsal pale 

 bands. Laterally, the prothorax has a small hair and accessory in 

 front of, and hehnv, spiracle; lower are two hairs on a level, just above 

 legs. On the mesothorax and metathorax, below the three hairs 

 already noticed, is a rather smaller one in a hollow ; then two on a 

 level, rather far apart, on a large lateral boss (lateral fiange ?) with 

 another below the front one, on a process of the same raised boss, then, 

 after some elevations unarmed, is a hair on a boss above leg. On the 

 lateral view, the dorsal hairs do not look so much in front as they did 

 on dorsal view, but the complicated wrinklings, to describe which 

 would be practically impossible, that denote subsegments, flanges, etc., 

 make clear demarcation of a segment difficult in the living larva. 



Mr. Buckler's figure of the larva seems rather large, and is much 

 paler than the specimen before me, those shown by Mr. Newman at 

 the meeting of the South London Entomological Society (June 24th, 

 1909) were also (one or two yellow at least) paler — possibly this one is 

 darkening for pupation.
