the trunks of oaks in the daytime, and may be some-

FAMILY XIV. HYBERNID.E 

 ANISOPTERYX JESCULARIA. 



This species is also common, and generally distributed 

 throughout the country. 



The female is perfectly apterous, but is readily dis- 

 tinguished from the female of the last-named species, 

 by the brush-like tuft at the extremity of the abdomen. 

 In the male the expansion of the wings is rather 

 more than 1J inch. The fore-wings are dull brownish 

 with an indistinct pale band before the middle, 

 edged externally with dark fuscous, and with a more 

 distinct pale band beyond the middle, much serrated 

 and edged internally with dark fuscous ; between these 

 bands is an elongate dark central spot ; the hind-wings 

 are very pale fuscous with a dark fuscous central spot. 



The larva is pale green, marbled with darker, with a 

 white subdorsal line. It feeds on sloe and hawthorn, 

 etc., in May. 



The perfect insect appears in March and the beginning 

 of April ; and the male may be constantly observed at 

 rest on palings, the fore -wings overlapping one another 

 so as to give it a peculiar elongate appearance ; some- 

 times we find it sitting on hedges at dusk, and it comes 

 rather freely to light ; the female is seldom met with at 

 large, but may sometimes be found by carefully search- 

 ing the hedges with a lantern ; it is more easily obtained
