Hemerobius formicaleonis . 
'The, Hemerobius of the formicaleo . 
This is a fpecies fo much more univerfally known in the reptile or worm-ftate, than 
in it’s more perfect form, that it can no way be fo expreflively named as from it: when 
in the perfect or ultimate flate, it is a fly with a long flender body, of a brown colour, 
a fmall head, with large bright eyes, long and flender, pale brown legs, and four 
large reticulated wings; it greatly refembles the former fpecies indeed in all things* 
but that it is more robufl, and wants it’s agreeable colour. 
The formicaleo or worm of this fly is about half an inch in length, and more than 
a third of an inch in breadth ; it’s body is of an oval figure, and is covered with little 
rough papillae, difpofed regularly in five longitudinal feries: the thorax is fmall and 
flender; the mouth is furnifhed with a very long pair of forceps, which incline toge¬ 
ther at the points, and each jaw has alfo three teeth in it; the legs are moderately long 
and whitifh ; it walks backward, and inhabits a hollow which it forms in loofe fand, 
in the manner of a funnel, where it preys on ants, and other Infe&s that fall into it* 
as almofl: every thing muft do that comes within the verge of it. 
It is common in molt parts of Europe, except England.

there is on each fide of the upper furface of the body a feries of little brown fpots.
