INSECTA. 
Astata, Latr. {Dimorpha,3uv.), has three complete sessile cubital cells, and the radial is appendiculated ; the 
eyes are contiguous, [especially in the males]. 
Nysson, Latr., has the same number of cubital cells, but the second is petiolated ; the radial is not appendicu- 
lated, and the eyes are wide apart. 
Oxybelus, Latr., has only one complete cubital cell, receiving a single recurrent nerve ; the mandibles terminate 
in a simple point, and the scutellum is spined. 
Nitela, Latr., has also only a single cubital cell, the mandibles terminate in teeth, and the scutellum is not spined. 
Pison, Jur., ditfers from all the rest in having the eyes emarginate. 
7. The last division of the Fossores, that of the Crabronides, differs from the preceding only in 
having the head generally larger and nearly square, the antennae often thickened at the tip, the 
abdomen oval or elliptic, w^ith the base narrower than the middle, and often pedunculated. 
Some have the antenna; inserted below the middle of the face, with the clypeus short and wide. 
Trypoxylon, Latr. {Apius, .Tur.), differs from the rest in having the eyes notched. T.figidus, [a very common 
British species, having the abdomen long and slender at the base]. The female makes use of burrows formed by 
other insects, in order to deposit her own insects therein, together with spiders for their support, closing the hole 
with fine earth. . 
Of those with entire eyes, some have the mandibles narrow, and mostly terminated by a point, and the antenna; 
close together at the base. , • a 
GorvUs Latr (Arpactus, Jur.), has three complete submarginal cells ; the mandibles of moderate size, and 
unidentate within ; the anterior tarsi are often ciliated. [See the monograph of Saint Fargeau in the Annal. Soc.

filiform • \he clypeus often glitters with silver or golden hairs. Some males are remarkable for the great dilatation 
of the anterior tibi^ and basal joint of the tarsi. The female of C. cribrarius provisions its nest with the larva; of 
a Tortrix found in the oak. Others employ dipterous insects for the same purpose. [See the monograph of Saint 
Fara-eau and Brull^ in the same y4wnaZc5.] , , i

The terminal Crabronites have the antenncE inserted nearer the middle of the face, and thickened at the tips. 
Psen Latr., has the clypeus nearly square, and the abdomen peduncled. i 
P^* 7 ««fto,Fabr., has the clypeus trilobed; the basal segment of the abdomen is narrowed into a knot, the 
antennae suddenly thickened, [and the abdominal segments not constricted], and all the cubital cells sessile.

THE THIRD FAMILY OF THE ACULEATED HYMENOPTERA, ^ 
The Diploptera, — 
Is the only one in this section which (with very few exceptions, Ceramias) has the fore-wings folded 
longitudinally; the antenna are ordinarily elbowed and clavate, and thickened at the tips; the eyes 
are notched; the collar extends at the sides as far as the wings; the fore-wings have two or three 
complete cubital cells, the second of which receives two recurrent nerves: the body is glabrous and 
black more or less varied with yellow or fulvous. Many live in temporary societies, composed of 
males’ females, and neuters. The females which have withstood the severity of the winter, com- 
mence the nest and take care of the young which they produce ; they are subsequently assisted by 
the neuters. 
We divide the Diploptera into two tribes, [JIfasanfe and .n 
The first, or the Masarides, have the antennae at first sight only composed of eight joints, the 
eighth forming with the following a nearly solid mass, with indistinct articulations; the upper wings
