BRITISH ICHNEUMONS. 275 



Common throughout the metropolitan district, in June and July, at 

 Darenth, Hertford, etc., and in Salop (Stephens) ; Lastingham, Yorks. 

 (Marshall) ; Essex. This is an abundant species in Britain. It has been 

 taken in the Pendand Hills, in March, by Evans ; at Rame Head and 

 Malvern, by Bignell, and at Mousehold, by Eridgman, in June ; at Reigate, 

 in July and August, by Wilson Saunders ; at Felden, by Piffard ; at Tos- 

 tock, Finborough Park and Wicken Fen, in September and October, by 

 Tuck ; near Guildford, by Butler ; at Colwyn and York, in October, by 

 Beaumont ; and at Darlay Dale, near Matlock, by Tomlin. I have found 

 it at Brandon, in Suffolk, in June ; but usually during or just after hiber- 

 nation, in Bentley Woods and at Ipswich, where the female is not un- 

 common in tufts oi Aim caespitosa and in moss, and subsequently in April 

 lurking beneath bits of wood and in the branches of Conijerae. When this 

 species is frightened it presses its legs to its sides, protrudes its antennae 

 close together and straight forward, and in this position will often roll over 

 and over without moving a muscle. \Vhen at rest, the antennae are held 

 straight forward, close together at the basal two-thirds, then abru{)tly curved 

 outwards laterally in a semi-circle. On the Continent it is very widely 

 distributed and extends to Algeria ; it has been bred from Depressaria 

 nervosa, and in Britain I have examined a female bred by Mr. Richardson 

 on nth September, 1891, from Gelechia plantagiiiella, at the Chesil Beach. 

 I have only seen one male example of this species. 



2. Cameroni, Bridg. 



Dicaelotns piiiniliis, Wesm. (partim). D. Cameroni, Bridg. Trans. Ent. Soc. 1881, 

 p. 146, pi. viii. f. 3; Holmgr. Ichn. Suec. iii. 363; Berth. Ann. Soc. Fr. 1S96, p. 342, 

 9 ; Thorns. O. E. xv. 1619, 6 9 . 



Head strongly nitidulous, with a few minute scattered punctures, black ; 

 frons finely and sparsely punctate ; palpi pale ; mandibles and clypeus of 

 $ fulvidous, of (j stramineous. Antennae fuscous, half length of the 

 body ; basal flagellar joints moniliform, ferrugineous ; $ with scape stra- 

 mineous beneath. Thorax shining, black ; pronotum often rufescent ; 

 mesonotum and scutellum finely and sparsely punctate ; metanotum finely 

 rugose, with complete areae ; areola sub-triangular, apically obtuse ; 

 petiolar area discreted, centrally slightly concave. Abdomen nitidulous, 

 black ; dull stramineous beneath ; margins of second and third segments 

 red ; post-petiole punctate, hardly aciculate laterally ; second segment 

 finely punctate throughout. Legs fulvous ; hind coxae, and sometimes 

 their trochanters, black ; anterior coxae and trochanters of $ stramineous. 

 Stigma dull stramineous; radix white; tegulae fulvidous. Length, 5-6 mm. 



This species is closely allied to the preceding, especially in its size and 

 in the nearly continuous genal costa, but it is much more shining and 

 finely punctate, the antennae are longer and more slender, the thorax a 

 little longer, the metathoracic sculpture finer, and the colour of the legs is 

 also distinctive. 



D. Cameroni was described from examples taken in Scotland by 

 Cameron and at Heigham and Earlham, by Bridgman, in August. I 

 possess two females, sent me by Mr. Donisthorpe, from Rossbeigh, in 

 Co. Kerry, in June, 1902 ; they both have the abdomen mainly red. 

 Two specimens were bred by Mr. Bankes from Swanage Buialis senescens, 

 Stn., on June 8th and 20th, 1895.
