106 LEPIDOPTERA. 



the specimen, informs me that it is PoUa Jiirjrocincta." It is 

 most interesting that Mr. Greening should have had the 

 pleasure of first making acquaintance with the larva, and he 

 has shown his usual acumen in predicting his captured 

 larva to be that of a species new to us, for there are few, if 

 any, Lepidopterists in this country who have a better eye 

 for specific distinctions than the gentleman in question. 



Mr. Hopley (Ent. Mo. Mag. vol. iv. p. 132), too, records 

 the occurrence of another specimen (a $ ), which was taken 

 by Mrs. Fisher, by daylight, from off" the window of a 

 lighthouse in Cornwall, about the middle of August, 18G2. 

 This interesting example, which Mr. Hopley had placed at 

 the head of his series of P.flavicinctay as a strange variety 

 of that species, had been unhesitatingly pronounced by 

 Mr. Greening, who saw it some year or so ago, to be alto- 

 gether new to our lists. 



Polia nigrocincta is placed by Dr. Staudinger between 

 Jlavicincta, S. V., and chi, Linn., riijicincta, Hiib., and ccb- 

 rulescens, Boisd., intervening between it and the former,. 

 argillaceago, Hiib., canesceiis, Boisd., and suda, Hiib., be- 

 tween it and the latter. In general cut, as well as in the 

 characters of the hind-wings, it appears to me to be moi'c 

 nearly related to clil than to Jlavicincta. The fore-wings 

 in colouration remind one of those o^ Jlavicincta ^ though 

 they have more the cut of clii, but the hind-wings of the 

 male bear great resemblance to those of clii, though they are 

 more strongly marked at the margin; the hind-wings of 

 the female arc darker than in clii $ , and have white cilia. 



M. Guenee also places it between Jlavicincta and chiy 

 with some species intervening. He remarks that it is as 

 common as, but less generally distributed than, Jlavicinctdf 

 that its time of appearance is July and August, and that it 

 varies excessively. It will be seen from the figure given at
