152 NOTODONTA DROMEDAR1US. 



quite cylindrical, smooth, the tail rounded, without a 

 spike, but with what might represent the end of a 

 spike, namely, two tiny diverging groups of rough 

 points; the skin rather glossy, in colour deep rich 

 red-brown. (J. H., 20, 12, 86.) 



NOTODONTA ZICZAC. 



Plate XXXIII, fig. 4. 



Mr. Buckler's note on this species is as follows : 

 " Feed on willow and sallow, two broods in the year, 

 reared the above from eggs received from G. Gascoyne, 

 Newark, 1857." His other date is June 11th, 1868. 



I have bred the moth in various years, April 26th 

 to May 18th, again May 26th, June 9th, July 11th and 

 14th. I found four eggs on sallow May 20th, 1868, 

 the larvae hatched May 27th, and I bred the moths in 

 the second week of July, thus confirming Mr. Buckler's 

 note on the double-broodedness of this species. In 

 1874, August 19th, I found two larvae on willow, and 

 bred the moths May 26th and June 9th, 1875. I have 

 also the record of a larva taken September 14th, 1861. 

 In 1886 Mr. Porritt sent me eggs June 9th, the larvae 

 hatched June 13th, moulted twice or thrice, but died 

 early in July. July 17th, Mr. Porritt sent me a second 

 supply of eggs, but somehow I could not get the larvae 

 to full growth. August 4th, Mr. Bignell sent me a 

 larva 20 mm. long, and August 6th Mr. Porritt sent 

 me two larvae, so altogether I was able to describe one 

 or two varieties. 



The egg is what is called button-shaped, slightly 

 domed above, and flat below, just 1 mm. wide, and 

 0*7 mm. high, the shell dull, very finely granulated; 

 colour at first whitish-green, afterwards dead white, 

 with a faint leaden tinge where the dark head of the 

 larva shows through. The young larva makes its exit 

 by a large hole in the side of the egg, but does not 

 eat the shell ; it is not quite 3 mm. long, with a large
