contrast of two sliades, the darker interiorly. Died the fourth 

 day after capture, having previously laid 10, 19, and 4 eggs, 33 

 in all. 



" No. 5. — Another pale specimen, but not so striking as the 

 last, having more dark markings towards the hind margin of the 

 wings. Laid 18 eggs on the second niglit, 19 on the tliird, 13 

 on the fourth, and died on the seventh after capture. 



" No. 6. — Caught three days later. Very dark central band, 

 the spaces on either side of it pale umber-brown ; an occasional, 

 but scarce, form at Dover. Laid 9, 16, and 2 eggs, and, the 

 weather turning cold, died third night after capture : 27 eggs in 

 all. [Note. — The umbrous ground colour became lighter in 

 appearance as the insect showed signs of wear.] 



" Nos. 7 and 8. — Not very distinct examples of a peculiar type. 

 Colour of central band and markings blackish brown, the paler 

 subterminal stripe distinctly divided by one or two waved unbroken 

 lines. Kept these, hoping to rear a lined var. like that shown. 

 Laid respectively 19 and 34 eggs, and died the third day. 



" These specimens were all caught on the wing, consequently 

 the appenrance of but one sex is known. 



" Notes on the Life-history. 



'•'The eggs of C. suffumata, like those of russata, are large in 

 proportion to the size of the insect. They are not laid in any 

 order, but scattered about in ones or twos ; from 35 to 40 would 

 appear to be the average number deposited, but out of a number 

 of freshly-developed specimens the extremes of '25 and 78 have 

 been noted. They hatch about the ninth day, and the caterpillars 

 grow very quickly, being full-fed about thirty days afterwards ; 

 thus but few are likely (in the South of England) to continue 

 feeding, even under exceptionable circumstances, longer tlian the 

 second week of June ; yet Newman, in his ' British Moths,' gives 

 the month of July for the date of their occurrence, whilst other 

 text-books assume the larvae to feed in the autumn and to hyber- 

 nate before attaining their full growth, which is quite contrary to 

 the experience of those who have reared the insect in this country, 

 and only explainable by an hypothesis of a second brood, which 

 we have not as yet ascertained to exist in nature. 



" The habits of the species whilst feeding are exceedingly 

 flltliy, and, after shedding their skins for the last time, the larvue.
