Hemikks.'] BRITISH ICHNEUMONS. I57 



testaceous and tegulae white ; areolet regular, with outer iiervure wanting ; 

 nervellus antefurcal. Length, 5 nun. 



Bridgman's insect agrees well (.■nough with this sjK-eics in its rough 

 metathorax and wanting areola, though it differs somewhat in the con- 

 formation of the post-petiole and abdominal coloration. He says, how- 

 ever, that it is the //. rufocincUis of neither (Iravenhorst, Taschcnherg, 

 nor Brischke ; it was taken by Dr. Ca[)ron, probably at Shere in Surrey. 

 Brischke tells us that he bred this insect from a species of the Tenthrcdinid 

 genus Feniisa, in Prussia. 



Referring to Marshall's article on Ifemimachus ins/abilis, Forst. (Cat. 

 1872, p. 46), the above synonymy must be deleted, since it is now con- 

 sidered that the present species is distinct from that of Ratzeburg, which 

 is still supposed to be the c? of iiis/al>iiis, but, if it is, it is synon) iiuuis 

 with the S assigned to it by Thomson as an undescribed insect.

Heiniteles varicoi-nis, (]r. I. K. ii. S37 ; Tasch. Zeits. ties. Nat. 1S65, \i. 121 ; Schm. 

 Term. Fuz. 1897, p. 532, 9. 



Head black, with the palpi and mandibles red ; clypeus discreted and 

 sparsely punctate ; face pubescent with the epistoma prominent ; frons 

 distinctly punctate and shining. Antennae short, filiform and apically 

 incrassate ; infuscate, with the five ba.sal joints fulvous, and the ninth to 

 eleventh white. Thorax black, mesonotum sparsely punctate and strongly 

 nitidulous with the notauli obsolete ; metathorax very coarsely rugose with 

 no distinct costae ; petiolar area not discreted. Abdomen glabrous, black, 

 with the second and third segments bright red, the latter usually black 

 apically ; basal segment aciculate with the post-petiole gradually explanate 

 apically and spiracles not very prominent ; the second glabrous ; terebra 

 one-sixth of the length of the abdomen. Legs testaceous ; the hind ones 

 with the tarsi, apices of femora and of tibiae, with the base of the latter, 

 infuscate or black. Wings somewhat narrow and evenly clouded ; the 

 narrow stigma and the costa pale piceous, with base of the former dis- 

 tinctly paler ; radix and tegulae pale stramineous ; marginal cell somewhat 

 short, nervellus antefurcal. Length, 3 mm. 



The sculpture of the metathorax, as described by Taschenberg, resembles 

 that of Pczomachus rather than Ifeiiiileles ; but I am inclined to suspect 

 some error here, for in all the specimens I have examined, which coincide 

 exactly in all other respects with this species, the areola is sufficiently 

 distinct (sub-parallel-sided, truncate at base and apex, longer than broad 

 and emitting the costulae slightly before its centre) and the apical trans- 

 verse costa is distinctly strong, but with no apophyses. 



Ur. Capron captured several specimens in the vicinity of Shere in 

 Surrey, from a study of which I have been enabled to elaborate the above 

 description. On the Continent it appears to be only known in dermany, 

 and has not yet been bred. I have taken females in July at the roots of 

 rushes at ^Vherstead and in tufts of Corex pixniaiinla at l''o\hall, near 

 Ipswich, late in November. \\'hen disturbed, even during hibernation, 

 this species does not feign death, like the majority of the genus. ICvans 

 has taken a ? at Bavelaw, near Edinburgh.
