42 BRITISH ICHNEUMONS. {Ephialtes. 



Sesia tnyopiformis (/.<:. iii. loc^), Pogotiocherus fasciculattis (p. 150) and Tinea 

 ahiefdla (p. 258). Probably several of the above records, especially the 

 last, refer, as almost certainly does Gravenhorst's mention of the male 

 with basally black coxae bred from AbTaxas gtvssulariata, to some other 

 insect : E. gracilis, Grav. was also several times bred from oak (Ichn. d. 

 Forst. iii. 109) and sometimes DasytiS — }iiger (p. 251) — appeared with it, 

 at others a Crabro and Raphidia (or Hemerobitis — cf. p. 261). This species 

 is said to be found a most effectual check to the propagation of the Codlin 

 Moth {Carpocapsa pomonella) in the apple-growing districts of California. 



6. strobilorum, Ratz. 



Pimpla strobilorum, Ratz. Ichn. d. Forst. ii. 94; iii. 100, t? ?. Ephialtes 

 strobilorum, Tasch. Zeits. Ges. Nat. 1863, p. 254 ; Thorns. O. E. viii. 744 ; 

 xix. 2124, c? ¥ . 



A shining black, unusually narrow and elongate species. Head 

 strongly dilated behind the eyes, with the vertex very broad ; palpi 

 stramineous. Antennae black. Thorax black with no pale radical 

 callosities ; metathorax nearly entirelv smooth, onlv centrally punctate 

 and not canaliculate. Scutellum black. Abdomen subcompressed, higher 

 than broad and very slender, black and very coarsely punctate, with the 

 tubercles subobsolete ; five basal segments longer than broad, the first 

 subcanaliculate centrally; terebra straight and a little longer than the body, 

 with the spicula stramineous. Legs yellow-brown ; all the trochanters 

 infuscate with the base and apex whitish ; all the coxae, the hind femora 

 almost entirely and the apices of the straight hind tibiae, black ; hind 

 legs elongate and their tarsi nigrescent. Wings iridescent ; radix and 

 tegulae whitish, the latter with dark spots ; stigma grey-brown. Length, 

 5-9 mm. 



Ratzeburg says that the ^ of this Pimpla differs from P. linearis only 

 in its dark hind femora, apically darker hind tibiae and in having the 

 abdomen more elongate with the four basal segments longer, though not 

 long enough to place it in the genus Ephialtes. The abdomen is, how- 

 ever, very similar to that of E. carbonarius ; and the species may be 

 known in the present genus by the posteriorly very dilated head, basally 

 black legs, of which the hind ones are dull red and the anterior femora 

 and tibiae pale testaceous. 



This species was first bred by Reissig in April and May from fir cones, 

 containing Anobium abietis, Tortrix strobilana, T. resinana and Tinea abie- 

 tella. It was introduced as British (Trans. Ent. Soc. 1886, p. 366) on the 

 strength of specimens of both sexes, which were bred by Bignell at the 

 end of May and the beginning of June from Coccyx strobilorum, presum- 

 ably not in Devonshire, since it does not figure in his county list (Devon. 

 Assoc. 1898). 



7. albispiculus, s^.«. 



Aver}' small, sublinear species with pale stigma and very obsolete tubercles. 

 Head nearly cubical, black with the palpi fulvous and clypeus obscurely 

 rufescent ; vertex very broad and convex, nitidulous with a few isolated 

 punctures and hairs, occiput bordered and centrally hardly emarginate ; 

 scrobes somewhat large ; face convex and subglabrous with verv sparse 

 short pilosity ; clypeus transverse, apically punctate, centrally deflexed
