272 BRITISH ICHNEUMONS. [Ophion 



8. longigena, Thorns. 

 Ophion longigena, Thorns. O.E. xii. 1191 ; lirauns, Arch. Nat. Meckl. 1889, p. 90. 



A very .stout species, rufcscent testaceous, with no trace of flavous 

 markings; anus of 9 determinately black from base of fifth segment. 

 Head large; vertex broad and temples distinctly a little broader than 

 eyes, from which both the ocelli and mandibular base are obviously 

 remote. Antennae not longer than body, attenuate and somewhat stout. 

 Metanotal carinae rarely weak, but petiolar area always elevated at base 

 of its two longitudinal central carinae. 7'hird abdominal segment sub- 

 constricted basally. Intermediate calcaria nearly equal in length. Wings 

 often distinctly flavescent, with nervelet short and distinct, discocubital 

 nervure convergent with upper basal and the red stigma somewhat nar- 

 row. Length, ig-22 mm. S9- 



Much stouter than O. luteus, with the colour clearer and the face apic- 

 ally parallel-sided. Th*^ cheeks are buccate and elongate, and the ocelli 

 remote from vertical orbits. I have none of the intermediate forms men- 

 tioned by Schmiedeknecht and consider it one of the most distinct species 

 of the genus in its very stout body and legs. One of my examples has a 

 distinct metanotal areola and it is possible, though very improbable, that 

 O. cosla/us, Ratz., with its contiguous ocelli, posteriorly slightly narrowed 

 head, etc., is synonymous. 



I fancy Thomson and Brauns can have known only the male of this 

 species, though neither specify sex ; it is said to have been bred abroad 

 from CucidUa forinosa and C. chamomiUac. A male, agreeing in every 

 particular with the former's description, was "bred at Corfe Castle on 

 4th July, 1901, from C. cha>no?7iUlae, Schiff., by E. R. Bankes; and Bridg- 

 man, who was uncertain that he correctly recognised it in bringing it 

 forward as British (Trans. Ent. Soc. i88g, p. 419), says a single example 

 with no capital flavous marks was bred on June nth, 1888, by Bignell 

 from C. scrophulan'ac. Both these moths are very rare in Suff'olk, which 

 may account for the uniqueness of my capture of three females of this 

 parasite upon the flower-tables of Heradeuin sphondylium on the South- 

 wold clifi's in the middle of July, 1901 ; I have worked the same spot for 

 ten years and seen no more ; it was upon this occasion that I noticed {cf. 

 Ichn. Brit. i. xxvi) that these insects are not easily disturbed when feed- 

 ing, but when they are thoroughly roused they fly off" hurriedly, careering 

 wildly like a Tipula, for a distance of twenty or thirty yards. Another 

 female was acquired without data from Clark's London collection ; and 

 Prof. Carr has sent me a male, taken on the wing at Langford Moor in 

 Nottingham on 2nd September, 191 1. The original locality is Tor- 

 ringeland near Malmo, at the south point of Sweden, in the latitude of 

 Dumfries; it has since been recorded from Germany only. 



9. longicornis, Brauns. 

 Ophion Ivngicornis, Brauns, Arch. Nat. Meckl. 1889, p. 92. 



Head very small and posteriorly constricted ; ocelli remote from eyes 

 and from each other; cheeks not short. Antennae of J half as long 

 again as, of 9 hardly longer than, the body. Mesonotum subinfuscate, 

 with two longitudinal testaceous lines ; basal metanotal carina weak,
