ON SOME BEITISH CYNIPIDJE.

iii. Thorax glabrous, not coriaceous, nor villose. Max- 

 illary palpi 4, — labial 2-articulate. 



Gen. Neuroterus, Hartig. 



The (^ unknown, except a single individual. — ? The radial cell 

 extends at least two-thirds of the distance between the areolet and the 

 tip of the wing : in Andricus not more than half the same distance. 

 The transverse A'eins and base of the radial are frequently clouded with 

 brown. The wings are longer : the abdomen more compressed, and 

 more constricted at the base. The antennae are longer, 15-jointed : in 

 Andricus $ only 13-jointed. Scutellum more prominent and more 

 depressed. 



Eleven species are described by Hartig, but so briefly, that without 

 German types it must be for ever impossible to identify those of our 

 country. These species are divided into two groups, according to the 

 sculpture of the mesonotum. In the former the sutures of the parap- 

 sides are visible, dividing the disc into three more or less convex arese 

 {N. Malpighii, inquilimcs, Beaumurii) : in the latter the mesosternum 

 is undivided, convex and glabrous, as in the genus Allotria, "Westw. 

 {N. defectus, poliius, &c.). 



It is probable that Mr. "Walker's description of this genus (Ent. 

 Mag. iii, p. 167, No. XXVI) refers rather to Spatliegaster, Hartig, for 

 he describes both sexes, and attributes 14 joints to the antennae of 

 the ? . 



Sect. I. Sutures of the mesonotum not invisible. 



Neuroterus Malpigliii, Hart. 



Blacjt ; inner orbits of theeyes,andgemtalia,ferruginous. Antennae 

 at the base and legs testaceous ; coxae, femora at the base, and hind 

 tibiae at the apex, more or less blackish. Abdomen strongly com- 

 pressed, carinated above. Wings hyaline, the base of the radial cell, 

 the outer side of the areolet, as well as the basal transverse vein, 

 incrassated, black, suffused at the edges with brown. The basal trans- 

 verse vein also emits two pale brown splashes, one triangular, reaching 

 to the areolet, the other following the course of the anal vein. $ . 



Long. 1 ; alar. exp. S^ liu.
