40 ABIA FASOIATA. 



proleg is 1 mm - 1-55 p.m., first moult began, 

 two or three (out of thirty-one) moulted or moulting. 

 Found the length of one quite recently moulted 

 to be 6*5 7 mm. Pace (with anal proleg) about 

 1 mm. 



June 20th, 6.30 a.m. Twenty-one (out of thirty- 

 one) have gone through first moult. The moulted 

 have not yet become ardoise ; the others have lost the 

 bloom for some time. There is no appearance of spots 

 in the moulted. Any increase of size in these is rather 

 in the knees than in length. Several of the unmoulted 

 measure 8 mm., and none of the moulted exceed this 

 length. 



June 21st, 7.5 a.m. All moulted but four. They 

 have mostly recovered the ardoise bloom, which at 

 last covers the black head. One measures 9*5 10 

 mm., another only about 8 mm. There is no trace of 

 spots yet. 



June 22nd, 6.30 a.m. Still one or two unmoulted. 

 Length, one, 9 mm., crawling pace nearly 2 mm. with 

 anal proleg. Another is 1 cm. long. On the other 

 hand, I find one moulted no more than 5'5 or 6 mm. 



June 23rd, 7.20 a.m. Measure, 1 cm. 8*5 mm. Two 

 still very small. 



June 24th, 8 a.m. Measure, one, 11 12 mm. The 

 yellow lateral spots are distinct under the lens in all 

 but one (which has never moulted). These colours are 

 proper to the larva after the second moult, and are 

 now shining through the old skin. 



June 25th, 7.25 a.m. Becoming de-ardoise prepara- 

 tory to the second moult. One measures about 11 

 mm., two others are 12 13 mm. ; others, again, much 

 smaller. 



June 26th, 6.50 a.m. Second moult well on ; earlier 

 moulted ones re-ardoise; black spots very distinct. 

 Great increase in breadth of head and anterior seg- 

 ments ; body still tapering posteriorly. No increase 

 in length about 12 mm. in both moulted and un- 

 moulted. Smaller ones measure about 10 or 9'5 mm. ;
