BRITISH ICHNEUMONS. • 247 



2. similis, Bridg. 



Pkaeogenes sifin'lis, Bridtj. Trans. Ent. Soc. 1881, p. 14S, pi. viii. f. 4, ? . 



Head tumidous, hardly narrowed behind eyes ; clypeus smooth, shining 

 and not depressed ; frons finely and somewhat closely punctate ; mandibles 

 piceous. Antennae slender, sub-incrassate apically, pale ferrugineous ; 

 scape black and four basal flagellar joints piceous al)0ve. Thorax black ; 

 notauli indistinct ; pronotum ferrugineous ; areola longer than broad, 

 semi-oval ; petiolar area slightly excavate. Abdomen cylindrical ; second 

 segment apically ferrugineous ; post-petiole sub-aciculate ; thyridii very 

 distinct ; terebra distinctly exserted. Legs slender : coxae mutic ; the 

 anterior piceous-red with femora, apices of tarsi and of intermediate tibiae, 

 infuscate ; hind legs fusco-piceous, with trochanters, base of femora, tibiae 

 and tarsi, rufescent. Tegulae pale, stigma dark. Length, 5-6 mm. 



This insect seems to be closely related to the preceding, and, although 

 the salient features of Mevesia were unknown to Bridgman, it would 

 appear to fall most naturally therein. 



One female alone is known, which was taken, by Biliups, in Britain, in 

 1880. 



3. cephalotes, Wesm. 



Fkaeogenes cephalotes, Wesm. Nouv. Mem. Ac. Brux. 1844, p. 197, i ? ; Bui. Ac. 

 Brux. 1855, p. 427, var. ? ; Holmgr. Sv. Ak. Handl. 1854, p. 47, 9 ; Thorns. O. E. 

 XV. 1651 ; Berth. Ann. Soc. Fr. 1S96, p. 381, {, ?. Proscus cephalotes, Holmgr. John. 

 Suec. iii. 421, i 9 . 



Head large, strongly punctate, dilated behind eyes ; vertex deeply 

 emarginate ; cheeks short and buccate ; genal costa inflexed, but not 

 elevated ; clypeus very short, sub-triangular, laterally sub-sinuate, dorsally 

 impressed and distinctly discreted ; mandibles elongate, stout, apically a 

 little narrowed, teeth nearly equal ; $ with second joint of palpi white. 

 Antennal flagellum stout, basally attenuate ; of $ broadly white-banded, 

 of $ ferrugineous apically beneath. Thorax narrower than head ; notauli 

 small ; metathorax of $. rugose ; areae complete ; areola not longer than 

 broad ; petiolar area discreted. Abdomen elongate, narrow, of ? sub- 

 acuminate apically ; centrally more or less rufescent ; post-petiole convex, 

 of $ coarsely rugose and bicarinate, of ? centrally smooth ; second segment 

 of $ basally rugose, of ? aciculate ; terebra shortly exserted. Legs black, 

 with anterior tibiae and apices of front femora usually rufescent. Wings a 

 little clouded ; stigma and tegulae black ; nervellus nearly antefurcal. 

 Length, 9-1 1 mm. 



The large head and stout form of this and the next two species, which 

 also seem to belong to Holmgren's genus Proscus^ superficially resemble 

 those of the aculeate genus Fe/iiphredon, and will serve to separate them 

 from those which follow. 



In Marshall's collection (Mus. Mason) is an example of this species 

 bred "From pupa oi Aeg. ( Sesia) cic/icifon/iis, Tilgate Forest, Sussex." I 

 do not think that it has before been bred ; Bignell has taken it, at Horra- 

 bridge, in the middle of September, and Piffard has given me a specimen, 

 from Felden, in Herts. ; there is another in Desvignes' collection. It has 

 a wide range throughout central Europe.
