This singular genus may at once be distinguished from 
féshna of Fabricius and Latreille, by the form of the stig- 
ma, the distance of the eyes, the triangular disposition of 
the ocelli, and by the lamella which terminate the abdo- 
men. From all other genera of its family, it may be dis- 
tinguished by the combination of characters above given.

I am indebted to my friend W. J. Hooker, Esq. for my

neuropterous insects, now preserved in the British Mu- 
seum.
