numerous divisions which he gave : this difficulty, however, is 

 greatly removed by Meigen in his last work, although I am 

 at a loss to account for his having dropped the Genus Spilo- 

 myia^ as his first subdivision of Milesia (none of which are 

 British) appear to belong to that Genus as at first established, 

 since from their posterior thighs being toothed they do not 

 associate well with our Genus Milesia : of his 2d subdivision 

 with posterior thighs without teeth, five species are described 

 by him, the only one of which found in this country is figured 

 in the Plate. 



It is now several years since this fine and rare insect was dis- 

 covered in the New Forest by Mr. D. Bydder, and the beginning 

 of June of the present year I took four near Brockenhurst ; 

 they appear to delight in settling in the thickest parts of the 

 Forest, where a partial shadow is thrown by the surrounding 

 foliage upon the trunks of trees, or the flat surface remaining 

 where they have been felled. 



The female is much more rare than the male (a figure of 

 which is given), and differs only in the eyes being separated 

 from each other, and the apex of the abdomen being more 

 acute. 



Having taken a pair off ILupliorhia amygdaloides (Wood 

 Spurge), which was full in blossom at the time, it is figured 

 with the insect.
