variety met with in some numbers in saltmarshes in a neighbouring 

 county, as above mentioned. The forewings of the male of this 

 variety are glossy reddish ochreous, with ferrugineous markings 

 (Fig. D), while those of the female are unicolorous, glossy, dark 

 ferrugineous. So striking is the contrast between these two 

 varieties, that the almost unicolorous heath forms at first raised 

 some doubts in the minds of more than one of our best entomo- 

 logists as to their specific identity. There seems no doubt that 

 the two forms differ only in coloration. The heath variety, 

 however, appears to be rather smaller than that found in the 

 saltmarshes. It has occurred also on a boggy spot near Studland, 

 where the larvae were found by the Rev. Charles Digby, in 1886, 

 feeding on the Bog-Asphodel, but it is known to feed also on 

 many other plants, among them being the stinking iris, marjoram, 

 and knap-weed. Mr. Digby had met with the perfect insect in 

 1885, as well as once previously. 



The perfect insect may easily be known from all its congeners 

 by the length of the palpi, which are porrected like those of the 

 genus Crambus, and are about three times the length of the head. 

 I have, since writing the above, seen examples from Ventnor (Isle 

 cf w '.ght) ; these are intermediate between the ordinary heath 

 and saltmarsh forms, and may be taken as typical.
