204 LEPtDOPTERA OF THE ISLE OF PURBECtf. 



feeds. The male expands 8J 9 lines, 

 while the female measures 11 12 lines. 

 It is thought by some to be probably a 

 distinct species ; but no tangible distinc- 

 tion has been detected between the 

 imagines or the larvae, and the difference 

 in the food-plants would readily account 

 for the difference in the size of the moths. 

 It is noticeable, however, that in the 

 ordinary form the males are, perhaps, a 

 trifle larger than the females, whereas in 

 this handsome sea form the females are 

 by far the larger of the two. 

 GRAPHOLITHA, Tr. 

 Grapholitha Cinerana, Haw., Corfe ; scarce. 



PHLCEODES, G. 



Phlosodes Immundana, F.K., Corfe ; the first brood has been 



bred sparingly from alder catkins. 

 SEMASIA, G. 

 Semasia lanthinana, D., Studland. 



Wceberana, S.V., Corfe, Holme, Studland ; the larva is 

 not uncommon under the bark of 

 fruit trees. 

 COCCYX, Tr. 

 Coccyx Nanana, Tr., Corfe, Studland ; scarce. 



RETINIA, G. 



*Retinia Buoliana, S.V., Studland, Rempstonc ; the larva is 

 locally common in the shoots of young 

 Scotch firs, doing considerable damage 

 to them. N.B. This species is 

 erroneously recorded in our former 

 list as R. Pinicolana, with which it is 

 constantly confused, and which has 

 not yet been met with in Purbeck. 

 Pinivorana, Z., Studland, Kempstoiie.
