p A N 0 R p A * 30 l)t Scorpion jflp. 
This is a fly of a moderate fize: it’s body is oblong and rounded ; it’s head is fmall, 
and is terminated by a hard, horny, oblong fnout, which is prominent downwards: 
the antennas are fetaceous, black, and compofed of no lefs than thirty articulations: 
the back is brown, the Tides are yellow, the wings are white, but have Tome dufky 
Tpots on them, which are difpofed in tranfverfe feries, forming a kind of lines j the tail 
is articulated, and is terminated by a weapon, refembling that of the fcorpion, which 
is bifid : Tome of the fame fpecies want this weapon, but this is only the difference of 
Tex, the females alone having it. 
The fly is common in our paflures in July : authors call it Mufca Scorpiura.

r T"’ A H E head of the Raphidia is of a horny fubffance, and is depreffed : the tail is 
X armed with a weapon of a fender form, fharp, horny, and fimple, not bifid 
at the extremity. Of this genus there is alfo but one known fpecies. 
Raphidia, 
This is of the fize of the fcorpion fly, and much refembles it in fhape: the head is 
black, fmooth, horny, narrow in the hinder part, and depreffed: the thorax is nar¬ 
row, rounded, and black : the antennas are flender, fetaceous, white, and compofed of 
a vaff number of articulations : the body is flender and oblong ; it is brown, but is 
variegated with tranfverfe lines of white : the wings are thin membranaceous, and re¬ 
ticulated with nerves, and have ufually each an oblong brown fpot toward the edge; 
they much refemble the wings of fome of the fmaller libellae: from the hinder part of 
the body of the female, there grows a long, fharp, flender, and arcuated weapon. 
It is common in July in our meadows, efpecially about waters. 
HEMEROBIUS. 
T H E palate of the Hemerobius is prominent, and has on each fide two tentacu- 
la : the wings are deflex and tumid. 
Hemerobius luteo-viridis , alls aqueis , nervis viridibus.

This is a very beautiful Infed: it is about three quarters of an inch in length : it’s 
body is very flender, rounded, and of a greenifh-yellow colour ; it’s wings are very 
large ; they are tranfparent and colourlefs in the intermediate fpaces; but the nerves, or 
ribs, are of a fine green, and are fo large and numerous, that the whole wing feems 
compofed of them : the eyes are very large, and of a fine gold yellow: the infed, when 
crufhed, flinks intolerably. 
The eggs of this fly are affixed by long pedicles to the leaves of our fruit-trees; they 
Hand in duffers ered, and refemble fo many pins ffuck into the leaf by the points. I 
lent a leaf with about forty of thefe eggs on it, laff fummer, to our Royal Society, 
where a favourite member declared them the eggs of a Tipula, and will not 
be convinced of the error, though this beautiful fly has been produced from thofe very 
eggs. The worm they immediately hatch into is what Reaumur, from it’s voracioufly 
feeding on the aphides, calls Leo aphidis: the fly itfelf has been called, by Mouffet, 
Mufca Chryfops; by Liffer, Tolmerus; by Petiver, Perla minima merdam olens 5 
and, by Goedart, Audax and Intrepidus.
