226 LEPIDOPTERA. 



(Rev. H. H. Crewe.) There are indications of two pairs of 

 prolegs, imperfect, in addition to the usual pairs. 



May to July or August, on privet, lilac, and currant — but, 

 according to Dr. Hofmann,on Smilax aspera, Genista, Cytisus, 

 and Jasminura. In the case of larvee obtained from eggs of 

 the second generation, the Rev. Joseph Greene recorded that 

 partial hybernation took place, and that they did not assume 

 the pupa state until towards spring. 



This larva is well known to be extremely sensitive to the 

 colour of its surroundings, its own colour being greatly 

 influenced thereby. 



Pupa long and narrow, cylindrical ; eye-covers shining, 

 not prominent ; tongue-case rather visible ; limb-covers com- 

 pact and smooth ; antenna-covers flattened and broadly 

 sculptured with the form of pectinations ; wing-covers laid 

 close, not thickened, nor sculptured, except in the most 

 minute pattern of raised lines; dorsal and abdominal seg- 

 ments sparsely and minutely pitted, but the hind band of 

 each smooth and broad ; anal segment fully rounded ; cre- 

 master very rough and bristly, and having a long bristly 

 hooked spike ; general colour very dark red-brown ; bands of 

 the segments pale brown. In a tough silken cocoon, con- 

 structed upon the surface of a twig, and covered with morsels 

 of the bark. 



The moth sits by day on the flat surface of a tree or paling, 

 with wings closely appressed to the wood, and there bears a 

 most accurate resemblance to a flat chip of wood, or to the 

 place where such a chip might have been broken awaj^ ; or, 

 if on the trunk of a lilac or cypress, or other shrub, it places 

 itself sideways, with wings straight up and down, and thus 

 perfectly imitates the scar of a torn-ofi" twig or small branch. 

 This should be seen, as I have seen it, to be appreciated ! At 

 dusk it flies about hedges and shrubberies, and will come, 

 though not commonly, to light. Especially attached to 

 gardens, and nowhere else so common as in those of the
