54 LLOYDS NATURAL HISTORY. 



Ill) states that specimens of this Butterfly, obtained from a 

 collector named Seaman, were distributed at a meeting of the 

 Entomological Club in September, 1S28, under the impression 

 that they were T. zv-albiim, then called T. pnini. Newman 

 noticed the difference, and succeeded in identifying the insect, 

 upon which Seaman gave out that the specimens were from 

 Yorkshire, which locality is given by Curtis, Stephens, and 

 even Duncan, although Stephens had corrected the error before 

 Duncan wrote. 



I have taken this species in Germany, flying round detached 

 sloe-bubhes, but not frequently, or in great abundance. By 

 far the commonest Theda in that country is T. ilicis, Esper, 

 which abounds in every oak-wood. This species has generally 

 an orange blotch towards the hinder angle of the fore-wings, 

 and an orange spot towards the anal angle of the hind-wings. 

 It resembles T. pruni, in the white hair-streak of the under 

 side not forming a W, but differs from it in wanting the round 

 black spots within the sub-marginal orange band on the under 

 side of the hind-wings. It has be:n reputed British, but 

 doubtless in error. 



GENUS CALLOPIIRYS. 

 Callophrys, Billberg, Enum. Ins. p. 80 (1820). 



This genus differs from the oth^r European Theche by the 

 absence of a tail, though there is a slight notch before the anal 

 angle of the hind-wings. It is also distinguished at once by 

 the green colour of the under side of the wings.
