ON THE PKOCTOTEYPID GENUS GONATOPUS, LJUNCH. 223 



generally ignored in Britain that a word of enlightenment may 

 be of service in general, the more especially as the genus to which 

 Mr. Hardy's insect belongs was left in a somewhat inconclusive 

 condition by the late Arthur Chitty in 1907. 



Subfamily Dryinin.e. 



This may be distinguished from all the other subfamilies of 

 the Proctotrypidie by baving : Head transverse, neither globulose 

 nor oblong; antennae ten-jointed and inserted close to the mouth; 

 scutellum wanting or broadly truncate basally, not tripartite ; 

 abdomen neither margined nor acute laterally ; front tibise with 

 a single bifurcate calcar, their tarsi ending in forceps ; wings of 

 female often wanting. 



Tribe Gonatopini. 



The Dryininae have been divided (Andre, Hym. d'Europ., 

 1904, p. 494) into three tribes, of which the present is dis- 

 tinguished by the extension of the prothorax to the tegula?, by 

 tbe lack of female wings, and by tbe very narrow, lanceolate 

 stigma of the male wings. 



Genus Gonatopus. 

 Distinct from other genera of the Dryininee in having : 

 Capital vertex broadly but not deeply concave, never distinctly 

 convex (as in Aniceon, q.v. E. M. M. 1908, p. 141) ; occiput 

 not margined (as it is in Antceon*) ; thorax hi- or tri-nodal ; 

 scutellum obsolete or wanting ; front legs raptorial, with pincer; 

 form tarsi; posterior tarsal claws neither bifid nor basally lobate- 

 wings wanting. Females alone known. — Some fifty species of 

 this genus have been described, of which thirty-five are European 

 and no more than eight have hitherto been ascertained as British. 

 Like everything he and Dr. Arnold Forster touched, M. I'abbe 

 J. J. Kieffer has split up old and well recognised species to such 

 an extent that the synonymy of even so little worked a genus as 

 the present is already considerably involved. In the following 

 table of the British species I have followed Chitty in the 

 Entom. Eec. 1907, p. 81, which is the last word we have had 

 upon the subject in England since the briUiant author died 'early 

 in the following year. 



Table of British Spkcies. 

 (4) 1. Second thoracic node with erect pilosity; vertex slightly 



excavate. 

 (3) 2. External joint of pincers armed beneath with 6-8 plates, 

 incrassate, with subapical tooth; internal joint in- 

 flexed before its apex, with plates in rows 



1. striatus, Kieff. 



* Amazon suba})tenis, Kieff (1904, p. 138), is, I believe, known only in a 

 unique Scots female. Mr. Ernest A. Elliott has kindly presented to me another 

 of the same sex, captured by him at Kingussie during August, 1912. — C. M.
