4 THE MOTHS OF THE BRITISH ISLES. 



Kane states that it is very rare in Ireland, and I fail to find any 

 record from Scotland. 



The range abroad extends to Japan. 



The White-spotted Pinion (Calymnia diffinis). 



This pretty species is shown on Plate 2, Figs. 6 ^ and 7 ^ • 

 Its colour and marking are little prone to variation. Some- 

 times the ground colour has less red and rather more purple 

 in its composition, and in some specimens the white marks on 

 the front margin are larger than in others. 



The caterpillar is pale green, with three whitish lines along 

 the back ; the central of these is rather yellowish, agreeing in 

 tint with the usual raised dots, and the outer ones are edged 

 above with bluish green ; head, brownish, inclining to black 

 below. It feeds at night, in April, May, and early June, on the 

 common elm, and rests during the day on the undersides of the 

 foliage or between leaves. (Plate 3, Fig. 3.) 



The moth is out in July and August, and is obtained at sugar 

 or at light, in almost all parts of England where its favourite 

 tree grows freely. It seems to be more local in the Midlands, 

 and appears to be but little known in the northern counties, 

 although a specimen was taken at sugar in Hazleden Dene, 

 Durham, in the autumn of 1898. 



y^ The Dun-bar {Cahmnia trapezina). 



\ On Plate 2 will be found portraits of four specimens of this 



variable species. Figs. 8 and 9 represent a male and a female 

 of the more ordinary forms. Specimens of the typical whitish or 

 greyish buff colour vary in the matter of cross lines, which are 

 well defined in the type, but absent in dh. pallida^ Tutt. Some 

 examples have a reddish central band, and in others the band 

 is blackish or black ; the latter are referable to ab. badiofasciata^
