1. Spathiiis ruhidus, Eossi. (PI. II., fig. 3). 



Ichneumon ruhidus, Eossi, Mant., App., ii., 110. 



Spathius ruhidus, Nees, Mon., i., 14 ; Hal., Ent. Mag., 

 iv., 42, ^ ? . 



Eufo-testaceous ; abdomen (except segment 1) black or blackish ; 

 tibise white at the base, hind tibiae annulated with fuscous ; coxae 

 and tarsi more or less pale. Wings fuscous, white at the base and 

 apex, and with a white fascia beneath the bicolorous stigma. 

 Terebra nearly as long as the abdomen. <? J . Length, 1 — 2 ; 

 wings, 1^ — 3^ hn. 



Antenna longer than the body, of the 5 29-, of the J 31-jointed 

 (in one specimen) ; front impressed and transversely striolated. 

 Thorax less shining than the head, coriaceous. Segment 1, and 

 base of 2, finely striolated; the rest smooth. The colours vary; 

 small specimens often have the thorax and petiole infuscated, and 

 the markings of the wings and legs subobsolete. 



Less common than the next species. I captured a 5 

 on an elm tree near E slier, another among larches in 

 Pre Wood, St. Albans, and <? ? out of an old hedge near 

 Abergavenny. Bridgman has taken two fine typical 

 females near Norwich. Their parasitism has not been 

 well traced ; Giraud supposes them to infest Xiphydria 

 dromedarius. Fab., which seems unlikely. Spathius 

 anohii, Gir., Ann. Soc. Fr., 1877, p. 415, bred by Perris 

 from Anobium longicorne, Sturm, is very like this species, 

 and conjectured l\y Perris to be identical. S. erythro- 

 cephalus, Wesm., Nouv. Mem. Ac. Brux., 1838, p. 131, 

 S $ , differs only in having segment 2 very smooth, and 

 may also be the same ; it has been bred by Wissman 

 from china ptinoides. Marsh. S. pedcstris, Wesm., is 

 an apterous form from Louvain, of which Wesmael had 

 only one specimen. 



2. S2)athius exarator, L. 



Ichneumon exarator, Lin., F. S., 1614, ? . 



Cryptus clavatus, Panz., F. G., cii., 16, 3 , badly 

 figured. 



Spathius clavatus, Nees, Mon., i., 12 ; Hal., Ent. Mag., 

 iv., 43; Wesm., Nouv. Mem. Ac. Brux., 1838, 

 p. 129, pi., fig. 16 (wing) ; Eatz., Ichn. d. Forst., 

 i., 48, pi. vii., fig. 10; ii., 42 ; iii., 41, <? $ ; S. v. 

 Yoll. Schets., ii., tab. 5, ? . 



TestaceoTis, varied with fuscous ; palpi, fore coxae, all the tro- 

 chanters, and tibiifi at the base, whitish, the last obscurely
