Formicaleo annulatus. 
Myrmeleon annulatus Klug, Symb. Phys. IV, tab. 36, fig. 7. 
The species is known from Spain. Navas remarks 
that.it is also known from Asia occident. Mac Lachlan 
(Entom. Monthly Mag., Vol. 25, p. 347) mentions it-from 
Benzus Bay, Morocco, but he remarks that his determi- 
nation is doubtful. I know the species only from the de- 
scription and the figure, given by Klug.

Tiny species. Legs and body slender. In the fore- 
wing the angle between Cuza and Cuıp very acute, en- 
closing two rows of cells; the second branch from Cua 
arises a little before the point where Cuzp runs into the 
hind margin. No anterior Banksian line; the posterior one 
slightly indicated. The apical area in both pairs of wings 
without crossveins*). Wings slender; their tip acute; the 
posterior ones slightly falcate at apex.

Neuroleon naxensis Navas, Revista Real Acad. Cienc. 
Madrid, p. 626, fig. 10, 1915. 
The species is found in Spain, South France, Italy, 
Greece and Asia minor. I have examined the type spe- 
cimen of N. naxensis and compared it with specimens 
from Spain, Sicily and Asia minor. 

*) This character is not constant. In some specimens before me (ex 
coll. Navas) one or two crossveins are present in the apical area 
of the forewing.
