My first acquaintance with the Mymaridae was made at 
Holloway, London, where, in the garden, surrounded by the 
usual “cats’ highway” (a four foot wall) I used to find 
Anaphes and Anagrus tolerably plentiful on hot sunny days. 
I have seen them flying, and have caught them in my hand; 
though more frequently they were entangled in the webs of 
the Garden Spider, Epeira diadema, but far too small for that 
individual to notice. It was in a very dirty web that I first 
found the long-sought-for gem My mar pulchellus, so no one 
living in town need despair of being able to find some of 
the Mymaridae. 
During the latter end of the summer of 1884 I obtained 
a large number of various species, representing the following 
genera, viz.:—Anaphes, Anagrus, Alaptus, Camptoptera, 
Cosmocoma, Gonatocerus, Litus, Mymar, and Ooctonus. The 
first to appear was Anaphes puncttim, which I found in June— 
flying, on various shrubs, walking about window panes, besides 
sweeping them from low herbage in fields and on banks. 
This is one of the strongest built, its black colour enabling 
it to be easily seen on windows, as it runs steadily up and 
across until it meets with some obstacle, when it immediatly 
hops oft* (I can scarcely call it flying) a short distance. The 
delicate yellow Anagrus moves along in the most graceful 
manner, its long fringed wings just sweeping the glass, and 
when needful altering its direction by a most fairy-like turn 
of its train ; when disturbed it quietly, and apparently with 
some difficulty, disengages its wings one from the other, then 
it takes a short flight, settling upon the glass again like a tiny 
speck of dust. 
Alaptus is the smallest, therefore the most difficult to see, 
rendered still more so by its habit of not putting in an appear¬ 
ance until September, and seldom before half-past four or five 
o’clock ; it has a most peculiar jerky gait, walking for about 
an incli-and-a-lialf; then off at an angle or back again for the 
same distance. 
Camptoptera too appears in September, and, like Alaptus, 
seems to prefer the waning light of day before taking its
