great number of joints (sixteen, and many more 1 ). Maxillary 

 palp.s, mostly five, articulate. 



A. Ichneumones adsciti, s. Braconides. A dis^oidal cell under 

 the first cubital cell extended to the margin of wing, not divided 

 a recurrent nervure. Second cubital cell frequently large. 



Aphidius NEES. Head transverse, with vertex broad. Abdo- 

 affixed by a short cylindrical petiole, incurvatile beneath the 

 ix. Borer not exsert. Antennae with joints very distinct, 

 rather few (eleven to twenty-four). Maxillary palps shortish (five- 

 or four-jointed). 



Sp. Ichneumon Aphidum L., Aphidius varius NEES, DE GEEB, Ins. II. PI. 

 30, f. 12, 13. (The fig. of PANZEB, Deutschl. Ins. Heft 95, Tab. 13, also 

 belongs to this species according to NEES.) This small species lays its eggs 

 in Plant-lice, in each one a single egg. The pupa of the Ichneumon lies 

 curled up in the body of the Aphis. See LEEUWENHOECK, Sevende ven-<>l'j

Alysia LATR. Head broad. Abdomen sessile. Borer exsert. 

 Mandibles subquadrate, with apex tridentate, divaricate (even when 

 drawn together, distant). Maxillary palps sexarticulate. Antennae

 species of this genus live in the pupae of Diptera, others in the larvae of 



Scarabcei.

1 Some species of the genus Aphidius NEES, of which HALIDAY forms the genus 

 Ephedrus, make an exception to this, and have only eleven or twelve joints in the 

 antennae.

 second order. See GOEZE, Naturforschcr, xil. 1778, s. 197 220.
