OCTOBER. 171 



oaks ? They are the males of Chimabacche Phryga- 

 nella, and their apterous females may be found on the 

 trunks of the oaks. The females differ considerably 

 in colour from the males, being light grey, with a dark 

 dash through their abbreviated wings. By beating 

 the oaks we shall obtain the extremely variable Ceros- 

 toma radiatella, and perhaps the beautiful Coriscium 

 sulphurellum likewise; while at sugar Calocampa 

 vetusta and C. exoleta, together with Chariptera 

 Aprilina and Miselia Oxyacanthce, occur; and by 

 beating we may obtain Hibernia aurantiaria and H. 

 defoliaria, while their apterous females may be found 

 on the trunks of the trees. This latter species, H. 

 defoliaria, is subject to great variation in the mark- 

 ings, some specimens being wholly of an orange colour 

 thickly sprinkled with black atoms. 



Let us now turn our attention to those species that 

 will be most likely to attract the notice of the tyro this 

 month, if he be really in earnest in his search ; and let 

 the Lithocolletides and Nepticidce have our first atten- 

 tion. This month is the best time in which to collect 

 them, the larvae being now nearly if not quite full fed. 

 On oaks we shall find the following species of Litho- 

 colletis, Roboris, hortella, Amyotella, lautella, querci- 

 folieUa, Messaniella, Heegeriella and Cramerella, 

 together with the following species of Nepticula, 

 atricapitella, ruficapitella and subbimaculella. In 

 hawthorn leaves we shall find the larvae of L. pomi- 

 foltella on the under side, and L. corylifoliella on the 

 upperside, together with the larva? of N. pygm&eUa, 

 Oxyacanthella, ignobilella and gratiosella; in sloe 

 leaves, L. spinicolella, N. plagicolella and Prune-
