Pupal suspension of Thais. 209 



about normal, intermediate between these and the shrunk 

 1st and 2nd. 



10.45. A few more movements, the changes of dimen- 

 sions of segments have placed the mouth parts and the 

 legs below the girth. They were not very definitely 

 above or below it before, but rather unrelated to it, but 

 a strictly lateral view made it cross over 2nd pair of 

 legs. 



11.35. Colour all but gone from warts of 9th abdominal 

 and claspers are almost collapsed, no other very obvious 

 change. Th. 64° Fahr. 11.50. Some movement occurring. 

 The large size of abdominal 4th, 5th, 6th and 7th very 

 conspicuous, the incisions being much expanded. The 

 appearance is as though the girth was holding up the skin 

 on 1st and 2nd abdominal and meta-thorax, but the 

 contents had gravitated back and distended these lower 

 segments. In this specimen the silk for the tail grip is a 

 little tag, a little loose and flocculent, shaped like a short 

 blunt thorn, of which the apex is at present opposite the 

 middle of the dorsal surface of 10th, the prolegs holding 

 the stem to which the larva is attached some 25 mm. 

 above it. 



12.30 p.m. Length of different portions of larva: 

 Head and 1st and 2nd thoracic = 3 mm., but these are 

 curved and are much more along dorsum. 3rd thoracic, 

 1st abdominal = 2 mm., i. e. 1 mm. each. 2nd and 3rd 

 = 3 mm. = 1-5 each. 4th, 5th, 6th = 7 mm., i. e. 

 2'3 mm. each ; 7th, nearly as much. 7th, 8th, 9th, 10th 

 = 5 mm. 



12.45 p.m. Strong movements of contraction in 2nd, 3rd, 

 4th abdominal segments, but quiescence elsewhere. No 

 definite vermicular movements. 



12.55. Regular vermiform movement from behind for- 

 wards, one every five seconds without so far much change 

 in skin. 



12.58. Tracheae drawn out along abdominal segments 

 2-7, loop drawn back, front segments straight. 



1.2 p.m. Split down back in usual way. Skin slips back 

 under loop. 



1.5. Skin behind loop. Scrap of broken-off tubercle 

 sticks to it ; loop lies in 3rd and 4th abdominal incisions. 



1.10. Skin gone. The movements of getting hold by 

 the cremaster move the loop to the thoracic abdominal 

 incisions, where it deeply indents wings during movements
