ADDENDUM, 



Since the previous pages appeared a new butterfly has been added 

 to the British List, viz. 



HESPERIA LINEOLA. 



Lineola, Och. Resembles Linea in size and colour, but the club 

 of the antennae is yellow, with a black tip ; the hind wings are uni- 

 colorous beneath instead of the inner margin being fulvous. The 

 black streak on the fore-wings of the male is shorter and quite straight, 

 sometimes it is wanting. 



The caterpillar is yellowish green with fine yellow lines on the back, 

 and a yellow line along the sides. The range of this species is more 

 extensive than that of Linea, as it is found thoughout Northern Asia, 

 as well as in Europe and North Africa, but it has only recently been 

 recognized in England. It occurs in meadows in July and August, and 

 is generally commonest along paths by the side of corn-fields. 



It was first recorded as a British species in the Entomologist for 

 January, 1890, by Mr. Hawes, as occurring in the County of Essex. 

 Mr. Whittle also records it in the February number as occurring in 

 abundance in July, on the marshes near Purfleet, close to Shoebury- 

 ness. 



I have been on the watch for this species myself for years, and 

 have come to the conclusion that it does not occur in the West of 

 England. It is probably an Eastern not a Western species in Britian.
