238 Mr. J. O. Westwood’s Description, Sc. 
of South African insects sent by Mr. Drege to Mr. Saunders an 
insect belonging to this subfamily, which in several respects seems 
more fully to confirm the Formicideous character of the group. 
The insect in question was indeed sent by Mr. Drege as an indi- 
vidual belonging to one of his species of ants, (No. 1485,) of 
which other specimens (being a true species of Formeca) were also 
sent. The insect disagrees in one or two slight respects from 
Mr. Shuckard’s character of #nictus, but I have not thought it 
necessary to propose a new subgenus for its reception. Of these 
characters the most striking are the slightly opaque whitish wings, 
with the veins and stigma almost concolorous with the membrane 
of the wing; the antennze gradually attenuated from the fourth or 
fifth joint, and the very clavate femora to all the feet: the palpi 
of this insect differ materially from those of Labidus.  ,
