Distribution. Mr. Morgan's types were from Deme-

 West Indies. 



I have never met with typical examples of A. dictyo- 

 sperfti/i, the puparia of which Mr. Morgan describes as 

 " greyish- white, with exuvia3 in the centre, depressed, 

 of an elongate oval shape, about 1*2 mm. longest 

 diameter. The centre of the larval skin is of a dark 

 orange colour, whilst the exuviae are of a light yellow." *
