92 PROORIS GERYON. 



am able to offer descriptions of the egg, the young 

 larva, the full-fed larva, aud the pupa. I hope I may 

 be able to bring the young larvae from this year's eggs 

 through the winter for better comparison with statices 

 next May. 



The females deposited their eggs sometimes singly, 

 but more often in little patches of five or six, placed 

 generally side by side in two rows. The egg is in 

 form and structure just like that of statices, but 

 perhaps a trifle smaller; it is also yellow in colour. 

 The newly- hatched larva is just over 1 mm. in length, 

 very stumpy, yellow, with small black head; the 

 trapezoidals combined in two large transverse tuber- 

 cles, each tubercular dot bearing one bristle. When 

 five weeks old my larvae were about 3 mm. long, some 

 more, some less. They had their tubercles by this 

 time set with fascicles of short bristles. The smaller 

 ones were dirty whitish on the back, with an edging 

 of dark brown, the lateral warts browmsh ; in the 

 larger ones all the brown had turned to dull purplish, 

 and the skin round the tubercles had become set with 

 tiny black points. Now, at three months old they are 

 about 5 mm. long, very plump, the back quite white, 

 with the tubercles on it very slightly brownish; the 

 distinctly double dorsal line is dull claret ; the scal- 

 loped line which borders the back is deep purplish, 

 the large lateral warts are dull claret, bordered below 

 with a whitish line, then comes a deeper claret line, 

 then another whitish line, and the two lower rows of 

 tubercles are brownish-pink. I cannot see such varia- 

 tion in colour as noted above for statices; they seem 

 rather more active, I fancy, than the larvae of statices, 

 unrolling themselves more quickly, and walking off 

 whilst under examination. 



The larvae sent to me on April 19th, 1886, and 

 again those on May 18th, varied very much in size, 

 some being full grown, and some even at the later 

 date no more than 7 mm. long, but I find I did not 

 note very much variation in colour. The full-grown
