and figures the female with t\v(j black spots on eacli segment, but 

 these do not show so clearly in any females I liave noticed. The 

 moths appear from the end of October onwards until the beginning of 

 February. The females crawl up the tree trunks, just in the same 

 way as the 'Winter iloths. The ova are deposited on the Inids and 

 twigs, in bark crevices and on p)runed surfaces. The caterpillars 

 hatch out later than those of the Winter Moth, usuallv in April. 

 Tiiey are readily told from the Winter INfoth by their colour ; the 

 back is chestnut-ljrown, and the sides a pale creamy-yellow to bright 

 yellow, the venter pale yellow to pale greenish-yellow, and the 

 spiracles pale with dark rims. Their means nf progression is just 

 like that of the former species. Wheir mature they reach 1^ inch 

 in length. They have been sent by varioirs correspondents as late 

 as July, but most reach maturity at the end of .Tune, they then fall 

 to the ground and pupate in the soil.
