the outside. The tibiie and tarsi are yellow, the former with a ring of black near the tips. In some specimens 

 tlio first segment of the abdomen has a yellow patch on each side, and between the second and third fascia is an 

 indistinct slender lino of yellow scales. 



Various localities are recorded for this species (the se.xes of which are so much unlike). It has been 

 taken in the woods of Surrey and Kent, in the London district, near Cheltenham, in the Clapham Park Wood, 

 Bedfordshire ; and my specimen was obtained by Mr. Weaver, with others from Shropshire. 



I have followed Ochsenheimcr and Stephens in the nomenclature of this species, it being customary in cases 

 where the se.xcs have been described imder different names to elect that of the male, although that of the other 

 sex may have the priority iti jioint of date. 



The larv;e is whitish, with a brown head, and is found under the bark of the oak and birch ; the iniaffo 

 appears in June.

This, the commonest British species in the genus, varies in the expansion of its fore wings, from eight to ten 

 lines. The colour is blue-black ; the palpi arc yellow ; the antennse black ; the thorax with a yellow line on each 

 side ; the breast with a j'cllow lateral spot ; the abdomen of the females with three and the males with four very 

 slender transverse fascitu. The tibiaj are black, with a ring, and the tips yellow ; the fore wings have the 

 margins and transverse bar black, the tip dirty golden colour, with black veins. 



The larva is of a whitish colour, with the head and feet brown, and a dark dorsal line. It feeds on the pith 

 of the common currant-tree. Some which I found in the larva state in April had changed to pupa> in the middle 

 of May, and appeared in the perfect state on the /ith of June. The moth is exceedingly active, and delights to 

 settle on the broad leaves of the currant in the hot sunbeams.
