922 INSECTA. 
The maxillz and labium are not prolonged. The second cubital cell 
is very small. The ovipositur, and even the abdomen are short. 
Microcaster, Lat. * 
Our third and last division, corresponding to that of the Bassus 
of M. Nées d’Esenbeck, has, like the first, four joints in the labial 
palpi, but the maxillary palpi consist of more, that is to say of six. 
The abdomenis semi-sessile. 
Here, the mandibles become gradually narrowed, and terminate as 
in the preceding Insects, by two teeth, or in an emarginated or bifid 
point. 
Hetcon, Esenb., 
Where the abdomen, viewed above, presents several annuli, termi- 
nates in a long ovipositor, and is not concave beneath ft. 
SicaLpuus, Lat., 
Where the abdomen is concave inferiorly, presents but three seg- 
ments above, and the ovipositor is contracted and resembles a sting f. 
Cuetonus, Jur., 
Where that part of the body,j otherwise almost similarly formed, 
is inarticulated superiorly §. 
There, the mandibles are almost square, with three teeth at the ex- 
tremity, one in the middle, and the others formed by the projection 
of the angles of the terminal margin. 
AtrysiA, Lat. || 
We have not yet been able to examine thoroughly, various cther 
genera established by Messrs. Gravenhort and Nées d’Esenbeck, in 
their Conspect. Gen. et Fam. Ichneum., and consequently hive not 
thought it proper to speak of them. T hat called Anomalon by Ju- 
rine, must be suppressed. It is a sort of general receptacle, where he 
has placed all those Ichneumons in which the second cubital cell is 
wanting, without paying any attention to other organic differences. 
In the second tribe, the Gatuicoum, Diploleparie, Lat., we find 
but a single nervure in the inferior wings. ‘The superior present 
some cells or areolz, viz. two at their base, the brachials, but of which 
the inner one is usually incomplete and but slightly marked, another 
radial and triangular, and two or three cubitals, of which the second, 
where there are three, is always very small, and the third very large, 
triangular, and closed by the posterior margin of the wing. The an- 
tenne are of equal thickness throughout, or gradually enlarge, but
