120 THE LADY BREEZE-FLY. 
I have frequently seen a train of pack-mules com- 
pletely scattered by these formidable pests. 
The largest and fiercest is the Black Breeze- 
fly (Tabanus atratus). His body is like glossy 
black velvet, frosted over with a delicate white 
bloom, like a freshly-gathered Orleans plum; 
it is about an inch in length; the wings, like 
pale blue gauze, when at rest are always kept 
in a horizontal position; the alulets are large 
and strong. The eyes are exquisitely beautiful, 
in colour dark-blue, but glittering with the lustre 
of highly-polished gems, and nearly covering the 
entire head. — 
The next in size is the Belted Breeze-fly 
( Tabanus cinctus), about one-third smaller than 
his sable brother. He is clad in bright orange 
livery, banded with stripes almost black; and 
has a most showy appearance, being decidedly the 
best dressed fly of the family. The eyes are 
emerald green, and, when viewed in the bright 
sunlight, have the appearance of being cut into 
numerous facets. 
The third or smallest is the Lined Breeze-fly 
( Tabanus lineatus), of a bluish colour, and marked 
only with a white line along the top of the head. 
In this fly the eyes are of bluish-green, and 
uuite as beautiful as in the two preceding.
