THE whole upper surface of this insect is of a fine 

 deep blue. The exterior margin in both wings has a 

 border of deep black ; the upper wings, a row of 

 equidistant, and the under ones a row of triangular 

 blue spots. On the centre of each wing is a lunated 

 black spot, betwixt which and the border on the 

 upper wings is a row of four oval black spots, and 

 on the lower wings, under the lunated spot, is a row 

 of similar shaped black spots, six in number. On the 

 outside of the black border, is a very narrow edge of 

 white, which is fringed. The body is purple above ; 

 and the whole under surface of the insect is pale 

 brown, studded thickly with black spots. 



The Mazarine Blue Butterfly is a very scarce 

 insect in this country ; and it does not appear to be 

 much more common in any other part of Europe. 

 We are as yet totally ignorant of its larvae.
