distinct variety from larvcC obtained from otlier parts of the 

 county. Perhaps the above were hii^^h in comparison, but it 

 seems very extraordinar\ that the same sallow bushes should 

 be supporting- at one and the same time, exactly under the 

 same conditions, three species, one ordinary in colour, and 

 practically showing- no variation ; another invariably almost 

 black, an absolute departure from the type ; and another, 

 of which above one-third were of the bri<^ht form mentioned, 

 with the remainder showing a nice s^radation between it and 

 the ordinary type. 



Another case of local \ariation came under my notice 

 last season, 1905, and one worthy of mention both from its 

 local sig-nificance, and the striking varial position in which 

 the species stands, when compared with its kind in other 

 parts of the county. In June last, on a heath about three 

 miles from here, and detatched from the moors, it was my g-ood 

 fortune to accidentally come across larvae of Agrofis agdthiua. 

 This in itself was regarded as a stroke of g^ood luck, for I had 

 not previously found the species in this district, nor had I a 

 specimen in my collection. From the larvae found fifteen moths 

 were bred. I suspected from the first that the specimens were 

 of a darker form than usual, but had no idea of the g^reat 

 difference that really existed between them and those from other 

 parts of the country, until Mr. G. T. Porritt pointed it out to me 

 when he saw them. It occurred to me that it would be 

 interesting- to compare them with others taken in the county. 

 The Rev. C. D. Ash, of Skipworth, very kindly sent for my 

 inspection a few of his forms taken near Selby. Of the five 

 specimens sent the following brief descriptions will perhaps be 

 sufficient for the purpose intended. 



No. I. Ground colour, lightish brown, with pinkish and 

 black dashes. Common. 



No. 2. Groundcolour, darker brown than No. 1, pinkish and 

 black not so prominent. Common. 



Nos. 3 and 4. \'ery worn, seemed to be rather sooty, and 

 markings not distinct. Very rare. 



No. 5. Ground colour a \cry pale pink, black niaiks not 

 conspicuous, except the black flash on which the discoidal spots 

 are placed. Rare. 



When compared with Mr. Ash's specimens mine were almost 

 black. With the exception of one the\- are all of one t\pe, with 

 a very short dirty pinkish streak at the base of the costa, the 

 discoidal spots small l)ut distiiict, the centre of the wing's a deep
