The eyes of the male with thick and long yellow grey hair, 
commonly without stripes ; of the female pale olive green, with 
many black, round, bright points, and a fine sloping darker line. 
Of the two other very troublesome Breeze Flies of distinct 
genera to the above, one is the very common Hccmatopota pluvialis 
(the Small Rain Breeze Fly, or Horse Breeze 
Fly), which especially harasses animals in 
stormy weather in summer. This is a little, 
somewhat straight-sided fly, not quite half an 
inch in length; the males blackish grey, the 
females whitish grey, and both sexes much 
covered with whitish hair. 
The eyes (when living) green above, purple 
below, with bluish stripes, or one coloured 
with stripes. The wings grey, and covered 
with little pale markings of short narrow 
stripes forming straight or curved lines, or even parts of broken 
circles, in all directions. When at rest the wings are placed like a 
roof over the abdomen. 
This species is noted by Dr. Taschenberg as “ an extraordinarily 
troublesome Breeze Fly.” Dr. Rudolph Scliiner notes the flies as 
numerous by roads and paths, and on hot days attacking the 
draught animals, especially horses. Also as being always at hand 
near water in the height of summer, and annoying bathers, and 
being so persevering in their attacks that they can be seized by the 
fingers without their flying away. The early stages appear to be 
still unknown. 
Genus Chrysops. Chrysops ccecutiens, Linn. “ Small Blinding 
Breeze Fly.” Eyes golden green with purple spots, and hind 
border, or stripe ; has distinct ocelli (that is, little speck-like eyes on 
the top of the head), three in number; and the antennas (horns) 
are longer than the breadth of the 
head, but without a crescent-shaped 
notch at the base. Wings when at 
rest expanded, as shown in accom¬ 
panying figure, to being about half 
open. Length from a third to two- 
fiftlis of an inch. 
General colour black in the male, 
but browner in the female, with a 
yellow band across the upper side of 
the base of the abdomen, bearing in the middle a dark marking
