216 MODERN CLASSIFICATION OF INSECTS- 
rylus Fab. and Labidus Jur., consisting of insects of which males 
only have yet been observed, but differing from the remainder of the 
family in the antenne being inserted close to the mouth, the head 
small, and the abdomen long and nearly cylindric. Saint Fargeau 
appears to regard them as more nearly related to the ants.* (Hist. 
Nat. Hym. p. 225.) The basal segment forms a strong knot. The 
maxillze and labium, undescribed by Latreille and St. Fargeau, are 
extremely minute. Mr. Burchell has informed me that the African 
species of Dorylus is nocturnal in its habits. 
The second division} of the predatory Aculeata corresponds with 
the genus Formica of Linnzus, and the HeTERoGyNa of St. Fargeau ; 
* Such also is the opinion of Mr. Kirby. (Monogr. Apum Anglia, vol. 1. p. 224.)

1 The first part only of this memoir, containing the Piedmontese ants (27 in 
number, 6 being new), described after the neuters alone, is here published. The 
author proposed to publish a more extended memoir ; but his recent death will, in 
all probability, prevent this intention from being realised. I may here mention, 
that M. Brullé proposes to publish a monograph upon this family.
