THE ENTOMOLOGIST. 



English. (Male.) 



Trochanters with a large black spot ; 

 femora and tibiae externally yel- 

 lowish, the yellow on femora 

 divided by a strong black line. 



Abdomen beneath marked longitudi- 

 nally with black. 



Hind wings 27-30 mm. 



Western Scottish. (Male.) 



Legs in the Mallaig specimens prac- 

 tically all black except distal lialf 

 of anterior trochanters and the yel- 

 low lines on all the tibiae. While 

 there is no reason to doubt that 

 the legs are much blacker always 

 than in the typical forms, there is 

 here and there just the faintest 

 trace of yellow on the femora, the 

 relics of a certain amount of that 

 colour which has become gradually 

 obliterated through age (see on 

 this point the slight discrepancy 

 in Mr. Lucas's two descriptions). 



Very broad black markings occupy 

 the greater part of each side of the 

 ventral suture, the red being re- 

 duced to mere streaks. Rounded 

 spots near genitalia small. 



Black lateral longitudinal mark- 

 ings much more strongly developed 

 than in the typical forms. 



Hind wings 25-5-27 mm. 



Two males (coll. W. JEvans), Glen Aros, Mull (August 6th), 

 and Morvern, Argyllshire (July), agree very well with the Mallaig 

 examples, that from Mull being especially dark. A female from 

 Moidart, Inverness -shire, in September (coll. Evans), has the 

 thoracic spots rather larger, and the femora distinctly lined 

 with yellow. 



A fine male from Talladale, Loch Maree, Eoss-shire (August 

 11th), which has the sides of thorax very darkly marked, has 

 distinct narrow yellow lines on the femora, while a female also 

 from the Loch Maree district is very similar to the Moidart 

 female (male and female, coll. J. J. F. X. King). Two very 

 small specimens (male and female, the latter teneral, hind wing, 

 male, 24 mm.) are also in King's collection, without label, but
