22 PLA FE, .CLXXXVIL 
About the year 1790, they were taken in great plenty near 
London, both at Batterfea and Highgate ; and have been met with 
in other places fince that time. Like the Ephemera, and other 
gaufe-winged Infe&ts, it delights in moult places, particularly among 
weeds. The larva is unknown, but is conceived to be of the aquatic 
kind. 
The wings are the moft pleafing objeéts for the microfcope that 
can be imagined: the reticulations and feathery edges are fo tranf- 
parent, that they may be examined with the deepeft magnifiers, 
which is an advantage few objeéts of fuch a fize poffefs. The 
magnified figure is given, with the natural fize in the annexed 
plate. 
Fabricius has erroneoufly quoted the feventh and eighth figure of 
the fifth plate of Scheffer’s cones, which is certainly no other than 
the common kind, Hemorobius perla, an Infeét often found in 
gardens, and remarkable for the fine golden colour of the eyes. The 
figure quoted in Su/zer and Avefe/ agree with our fpecimen.
