line three anterior marginal setae and. two posterior setae. 

 Supraspiracular and prespiracular tubercles each have three 

 setae. The spiracle is circular in shape, and posterior. A 

 tubercle above the legs has two setae. 



Meso- and post-thoracic segments : Trapezoidal tubercles 

 appear to be coalesced, forming large dorsal tubercles with 

 about six setae. Supraspiracular has about eight setae, 

 slightly below which a small posterior (subspiracular) tubercle 

 has a single very fine seta ; a larger anterior subspiracular 

 tubercle has a single seta. Tubercles above the legs have two 

 setae. 



The thoracic legs have spinulose hairs, and terminate with 

 a long claw, a rudimentary claw, and a flattened seta, to 

 which Dr. Chapman gives the name " battledore palpus " 

 in describing Arctia caia.* 



Abdominal segments (vol. xxxiii., pi. ix., rig. 18) : Anterior 

 trapezoidal tubercle has three setae, posterior trapezoidal one 

 seta. Supraspiracular tubercle is anterior above the small cir- 

 cular spiracle, and has about seven setae. One subspiracular 

 tubercle is below the spiracle, but posterior to it, with one 

 seta, and almost beneath this, but a little anterior, is another, 

 with a single seta, and still lower a tubercle-like area without 

 seta. On the base of abdominal feet are one spinulose seta, 

 one smooth seta ; on the footless segments 1 and 2 these rise 

 from a subventral tubercle and are both spinulose ; the sub- 

 ventral tubercle of segments 7 and 8 have only one seta 

 (spinulose). Segment 9 has a very large dorsal multi- 

 sttiferous tubercle, one lateral, one subventral, each with 

 only one seta. Segment 10 has a dorsal multisetiferous 

 tubercle, a lateral spinulose seta, and some setae on claspers ; 

 also on each side of the anal orifice a single smooth seta 

 curved upwards. On all the segments one seta of each 

 supraspiracular tubercle is about twice the length of any 

 other. Mr. Howes mentions the presence of several long 

 grey hairs from the anal extremity. This is a very striking 

 feature, and persists, I believe, until the larva is full fed. 

 These hairs are actually the post-trapezoidal setae of abdo- 

 minal segments 7 and 8, which are about four or five times 

 the normal length, are spinulose throughout, and greyish 

 beyond. 



Second Skm. — Length immediatelv after ecdvsis J§L in. 

 The tubercles, being more setiferous, are larger, and form 

 very prominent elevations on all segments. The skin is 

 yt-llowish-brown, the setae brown and spinulose 



Head has spinulose setae, but not noticeably more nu- 

 merous than in first stage.
