THE SPRING AZURE BUTTERFLY. 283

 but should a cloud obscure the sun, or a breeze chill 

 the air, their ardour becomes abated, and contention 

 ceases. 



The papilio phlaeas enjoys a combat even with 

 its kindred. Two of them are seldom disturbed, 

 when basking on a knot of asters in September, 

 without mutual strife ensuing. Being less affected 

 by cold and moisture than the argus, they remain 

 with us longer, and these contentions are protracted

 birth, we find the margins of its wings torn and 

 jagged, the elegant blue plumage rubbed from

 insect unknown in our district, or at least unnoticed 

 before by me; a pretty little blue butterfly, for 

 which I know no common appellation, and so have 

 named it the " spring azure," (papilla argiolus). 

 It appeared quite at the end of April, and in some

 then in bloom ; but, leaving all herbaceous plants,

 the nectaries in their blossoms. If this butterfly 

 be anywhere common, it may be mistaken by in-
