but its extreme western limit seems to be at Weston-super- 

 Mare, Somerset. 



[T. spini, Ri'ih., a species of about tlie size of T. pruni 

 and T. ir-album, and similar to them, but with a large spot 

 of blue at the anal angle of the hind wings beneath ; was 

 recorded as British by several of the earlier writers, and 

 reference especially made to a specimen said to have been 

 captured in Norfolk by the late Mr. J. Sparshall. In the 

 collection of this gentleman, now in the Norwich Museum, 

 I found a specimen labelled " spini," but without locality or 

 any note of capture. It proved not to be the true T. spini, 

 but apparently a North American species, and there is no 

 reason to suppose that T. spini has ever been taken in this 

 country. It is a common species in Central and Southern 

 Europe.] 



[T. ilicis, Esp., another dark species, rather larger, and 

 having a dull orange patch on the fore wings, was introduced 

 as British in Westwood and Humphrey's " British Butter- 

 flies," but on evidence so slight that it was substantially 

 rejected. There is no reason to believe that it ever occurred 

 here. It is a native of Southern and Central Europe, and 

 attached to the evergreen oak.] 



3. T. pruni, L. — Expanse, l\ to H inch. Dark brown, 

 faintly edged with orange. Under side with a white line, 

 and a black-spotted orange margin. Tail short. 



Dark brown. Male having a row of two or three indistinct 

 orange crescents at the hind margin of the hind wings. 

 Female larger, with the band of orange crescents more 

 distinct, and the fore wings having some faint orange clouds 

 along the hind margin, most distinct at the anal angle. Tail 

 in both sexes broader and rather shorter than in the last 

 species. Under side golden brown, with a very slender bluish- 

 white line across both fore and hind wings, the fore wings 

 having a faint incomplete orange band of spots along the
