4.44, Mr. R. McLachlan on Myrmeleon. 
Tf, therefore, our system of nomenclature be limited to 
the twelfth edition of the ‘Systema, as is the custom 
with many naturalists, the familiar spotted-winged Ant- 
lion, usually known as formicarius, is in the position of 
being nameless; but as this species was evidently that 
intended by the diagnosis in the tenth edition, with the 
name formicaleo, we may very justly retain both names, 
and the species and their synonymy will now stand as 
follows :— 
1. Formtcatzo, Linné, Syst. Nat. ed.x.; Poda. 
Formicarius (Vallisnieri; Réaumur, Geoffroy ; Roesel, 
tab. xvii.-xx.; Sulzer*), Fabricius; Olivier; Panzer; 
Latreille; Stephens; Rambur; Westwood; Burmeister ; 
Brauer ; Hagen; McLachlan, olim.; etc. (nec Linné, Syst. 
Nat. ed. xii.). 
2. Formicartus (um.), Linné, Syst. Nat. ed. xii. 
(Schiffer, ‘Elementa’ et ‘Icones’; ft Roesel, tab. xxi. fig. 
2); Dahlbom; J. B. Fischer ; Wallengren. 
Formicaleo, Linné, Faun. Suec. ed. ii. (nec Syst. Nat., 
ed. x.); O. F. Miller. 
Formicalynx, Burmeister; Hagen; Brauer; McLachlan, 
olim (nec Linné). 
Innotatus, Rambur ; Costa. 
Neutrum, Fischer v. Waldheim. 
[3. Formicatynx, Linné, Syst. Nat. ed. x., et ed. xii. 
(Species Africana, indeterminata). | 
I have already stated that no species of Ant-lion has 
been detected in the British Isles: t and I do not believe 
that such insects exist here, But if my views in this re- 
spect should ultimately prove to be erroneous, it may be 
that, mstead of the spotted-winged species (formicaleo) , 
its plainer congener (formicarius) , of Swedish notoriety, 
will assert its claim to a place in our lists. 
* Those authors whose names are included within the brackets, apply 
no trivial names to their insects. 
The figures in Vallisnieri’s ‘Opera’ (1733) are of extreme coarseness, 
and, in some of them, intentional caricatures of the human face, or figure 
are introduced, a practice not confined to him only among the earlier au- 
thors. The figures of the magnified larve are good. 
+ Hagen (Stettiner ent. Zeit., 1866, p. 439) refers the figure in Schaf- 
fer’s ‘ Elementa’ to No. 2, and those in the ‘Icones’ to No. 1. In both 
works the species represented is No. 2 (formicarius). 
{¢ The spotted-winged species has been erroneously recorded as British, 
by Barbut.
