HYMENOPTERA, 241 
Myzine, Lat., 
Where the mandibles are dentated *. 
Meri, Illigq., 
Where they are not dentated f. 
Sometimes the second joint of the antennze is exposed, as in Sco- 
LIA proper, or 
Scotia, Fab.t 
2. Those Fossores in which the first segment of the thorax is 
formed as in the preceding ones, where the legs are still short, but 
slender, and neither spinous nor strongly ciliated, and where the an- 
tenn in both sexes are at least as long as the head and thorax. 
Their body is usually smooth, or but very slightly pubescent. This 
subdivision embraces the family of the Saricyrss of Latreille, a name 
derived from that of the principal genus 
SAPYGA. 
In some the antennze are filiform or setaceous, as in 
Tuynnus, Fab., 
Where the eyes are entire § 
PoLocurum, Spin., 
Where they are emarginated, and the mandibles, besides, multi- 
dentated ||. 
In the others the antennz are thickest at the extremity, or in some 
males even clavate. ‘Their remaining characters are those of the 
Polochra. Such is Sapyga proper, or 
Sapyea, Lat. 
These Insects flit about trees and walls, exposed to the heat of the 
sun, and appear to deposit their eggs there 4. 
The Ceramii of Latreille, according to the form of the first seg- 
ment of the thorax and their extended or applicated wings, belong to 
this subdivision ; but more important affinities place them in the family 
of the Diplotera. 
3. Fossores still allied to the preceding in the extent and form of 
the first segment of the thorax, but in which the posterior legs are at 
least as long as the head and trunk, and the antennze are most fre- 
quently slender, formed of elongated, lax, or but slightly compact and 
suongly-arcuated or curled joints, at least in the females.

§ Lat., Ibid. The Scotene of Kliig appears to me to differ but slightly from the 
Thynni; they have the same kind of antenne, similar wings, the first cubital cell 
also traversed by a small line, &c. The anus of the males is slightly recurved, a cha- 
racter which approximates them to Tengyra, and various other divisions of the pre- 
ceding division.
