92 A FRAGMENTARY PAPER ON THE LARVA!., ETC. 



bearing 1 hair, below which is a large tubercle, slightly posterior, 

 with one hair. Post thorax corresponds with meso-thorax, and 

 the legs on each with pro-thorax, no spiracles. Abdominal 

 segments : 1st situate on the large dorsal swollen areas of the 

 principal sub-segment are the two dorsal tubercles (anterior 

 trapezoidals) one on each side, separated by a thin median line 

 along the back. These have one hair. The posterior trapezoidals 

 are remote, smaller (more lateral) with one hair on the posterior 

 edge of the next sub-segment. Spiracle large, situate about f 

 down the anterior sub-segment (from the median line) on the 

 anterior edge if not actually on the intersegmental membrane ; 

 above the spiracle slightly posterior is a swollen area with a 

 tubercle bearing, one long, one short, hairs (supra spiracular 

 tubercle) ; immediately posterior to the spiracle is a large 

 swelling bearing two remote hairs ; below the spiracle is a large 

 swelling bearing one hair, and below this a sub-ventral swelling 

 bearing two hairs ; 2nd abdominal segment, corresponds with 

 1st except that on the large sub-spiracular swelling are two 

 scarcely distinguishable remote tubercles, each with one hair 

 (posterior and anterior sub-spiracular tubercles) ; 8rd abdominal 

 .segments, corresponds with 2nd except there is no sub-ventral 

 swelling, the pro-legs having instead four single hairs at the 

 base, the 3rd, 4th, 5th, 6th, abdominal segments having pro-legs, 

 and correspond in other respects. 7th corresponds with 2nd ; 

 8th correspond with 7th ; 9th has the anterior trapezoidals small 

 and more remote than are the posterior trapezoidals, the supra- 

 spiracular tubercle is small and has only one hair, the latter and 

 three other tubercles (one hair each) are situate one below the 

 other on the posterior edge of the segment. 10th has three 

 single hairs above the anal fold and the leg has two single hairs 

 at base. Ventral aspect under one inch objective. 



Immediately at the base of each leg of the thoracic 

 segments on the posterior ridge is a single hair ; 1st and 2nd 

 abdominal segments have four tubercles each, with one hair 

 each, arranged transversely (from side to side of segment) 3rd, 

 4th, 5th, 6th, have one hair at the base of each pro-leg on inner 

 side. 7th has two tubercles at either side with one hair each, 

 arranged longitudinally. 8th has only the outer most tubercles, 

 and an inner hair marking the transverse position (as on 2nd) 

 of the tubercles. 9th has two single hairs only. 10th has 

 several hairs on inner side of claspers.
