a great number of joints (sixteen, and many more!). Maxillary 
palps, mostly five, articulate. 
A. Ichneumones adsciti, s. Braconides. A discoidal cell under 
the first cubital cell extended to the margin of wing, not divided 
by a recurrent nervure. Second cubital cell frequently large. 
Aphidius Nees. Head transverse, with vertex broad. Abdo- 
men affixed by a short cylindrical petiole, incurvatile beneath the 
thorax, Borer not exsert. Antenne with joints very distinct, 
rather few (eleven to twenty-four). Maxillary palps shortish (five- 
or four-jointed). 
Sp. Ichnewmon Aphidum L., Aphidius varius NEES, DE GuER, Ins. 1. Pl. 
30, f. 12, 13. (The fig. of Panzer, Deutschl. Ins. Heft 95, Tab. 13, also 
belongs to this species according to Nrxs.) This small species lays its eggs 
in Plant-lice, in each one a single egg. The pupa of the Zchnewmon lies 
curled up in the body of the Aphis. See LEEUWENHOECK, Sevende vervolg 
van Brieven, bl. 225—294, 134e Missive van 26 Oct. 1700, (and the fig.

Scarabet.

1 Some species of the genus Aphidius Neus, of which Hatrpay forms the genus 
Ephedrus, make an exception to this, and have only eleven or twelve joints in the 
antenne.

second order. See Gouze, Naturforscher, X11. 1778, s. 197—220,
