122 BRITISH ICHNEUMONS. 



9. subquadratus, Thorns. 



Ichneumon lalralor, varr. i and 2, Wesm. Mem. Ac. Brux. 1844, p. 63, i. I. stib-

Black, antennae filiform, thick, tricoloured, basal joints rarely clear red; 

 abdomen red, apex black, with two white marks ; Jegs red, apices of hind 

 femora and tibiae black ; areola quadrate, costulae distinct. 



Very like the last-described species in contour, size and structure of the 

 gastrocaeli and antennae ; but is said to differ from it in having the meta- 

 thoracic spiracles in both sexes larger, the areola shorter, sub-quadrate ; $ 

 head strongly triangular viewed from in front, cheeks not buccate but 

 coarsely punctate ; flagellum with its basal joints not entirely red, and its 

 pale band composed of five or six joints ; petiole finely sub-striate apically ; 

 $ face, apically truncate clypeus and mouth, flavous ; antennae croceous, 

 black above. 



Doubtless common, though less so than the preceding, with which it has 

 hitherto been mixed, and consequently unrecorded in Britain. It is very 

 often found in direct company with /. hiirafor, of which it is, perhaps, 

 but a variety. The Mound, Sutherland (Yerbury) ; Bury St. Edmunds 

 (E. Saunders) ; Greenings, near Reigate, in 1872 (ex coll. Wilson 

 Saunders) ; Dover and St. Margaret's Bay (Sladen) ; Oulton Broad, 

 Suffolk (Bedwell) ; Hastings District (Bloomfield) ; New Forest (Chawner). 

 It is common about Hastings, where I have found it at Brede, Battle and 

 Peppering, and about Ipswich, in moss and tufts of Aira caespitosa ; 

 Ewell, near Epsom ; Oxshott. The males are found in July and August, 

 but I have only found the females in the winter during hibernation. No 

 brachypterous form of this species has hitherto been noticed. On 17th 

 August, 1901, I captured a curiously malformed example of the male 

 flying, at Lyndhurst, Hants. ; this had the petiole normal, but the second 

 and third segments were connate, dull and contorted, nearly half as long 

 again on right side, which was much more produced than on the left, and 

 only discreted at the sides ; the fourth segment was nearly as long as the 

 two preceding together ; the next two extremely short, the fifth being 

 deeply transversely sulcata throughout ; the seventh normal. 



10. spurius, Wesm. 



Ichnewnon spurhis, Wesm. Bui. Ac. Brux. 1848, p. 162 ; Berth. Ann. Soc. Fr. 1894, 

 p. 580, ? . 



Very like the two preceding species, but at once distinguished from 

 them by its black hind coxae and quite smooth petiole. 



Head black, palpi and clypeus laterally reddish, the latter arched above. 

 Antennae short and filiform throughout, black, white-banded. Thorax 

 entirely black; areola sub- rectangular, about twice longer than broad; 

 costulae obsolete. Scutellum black. Abdomen black with segments one 

 to four red, seventh dorsally white ; post-petiole centrally smooth through- 

 out, with no trace of aciculation ; gastrocaeli normal. Legs black, tibiae 

 and tarsi red, apically black ; hind coxae black. Stigma red. Length, 

 5-6 mm. 6 unknown.
