134 BRITISH ICHNEUMONS. 



23. militaris, Grav} 



Ichuennion militai-is, Gr. Mem. Ac. Soc. Torin, 1820, p. 310 ; I. E. i. 342, excl. i 

 Ste. III. M. vii. 172; Wesm. MiJni. couron. Ac. Belg. 1859, p. 40; Berth. Ann. Soc. 

 Fr. 1894, p. 654, 9. /. extcnsoritis, var. i, Wesm. Bui. Ac. Brux. 1848, p. 155. 



9 . Head black, cheeks not buccate. Antennae white-banded, bi- 

 coloured, filiform and not attenuate apically* Mesonotum entirely black ; 

 areola sub-quadrate or only slightly longer than broad. Scutelluni white. 

 Abdomen black, segments two and three red, six and seven dorsally white; 

 post-petiole not gibbous, regularly aciculate ; gastrocaeli not transverse. 

 Legs black, tarsi not dilated ; anterior tibiae internally flavidous ; hind legs 

 entirely black, their coxae probably not scopuliferous. Stigma piceous ; 

 tegulae brown. Length, 9 mm. 



This doubtful species was described by Wesmael as a variety of /. 

 exfensorius, with which it agrees entirely in sculpture, differing only in the 

 colour of the hind legs ; Berthoumieu, however, thinks it " probable " that 

 it bears no scopulae. Till this latter point were decided, it would perhaps 

 be better to consider it as a mere variety of that species. 



Not very common ; found in the spring, near London, and in Salop 

 (Stephens, October, 1835). I know of no other records from Britain, 

 and it would appear to be known on the Continent only from Piedmont, 

 whence it was originally described. 



24. albicollis, IVesm. 



Ichneiunon albicollis, Wesm. Bui. Ac. Brux. 1857, pp. 371, 372 ; Thorns. Ann. Soc. 

 Fr. 1887, p. 5 ; Berth, lib. cit. 1894, p. 649^ Thorns. O. E. xviii. 1922, i ?. 



Head black ; of $ with palpi, mandibles and frontal orbits usually red ; 

 of $, with palpi, mandibles, clypeus and face, stramineous. Antennae 

 black ; of ? very slightly attenuate at apices, centrally white-banded ; of 

 $ with scape stramineous, flagellum fulvous, beneath and joints six to 

 twenty internally carinate, the basal four with no tyloides. Thorax stout, 

 black with pronotum white in both sexes ; $ with lines before and beneath 

 radix pale ; areola quadrate, or in $ a little longer than broad ; costulae 

 wanting. Scutellum white. Abdomen of $ oblong-ovate, black with seg- 

 ments two, three, and basal angles of fourth red, the third being sometimes 

 basally black, sixth and seventh white-marked ; of $ with segments two, 



1 Ichneumon miniitoriiis, Desv. Cat. 25, <? ; cf. Mori. E.M.M. 1902, p. 123. 



This appears to be a good species as far as it is known. For tiie present, however, I prefer to 

 omit it from our list, pending the discovery of its true position and possible synonymy. It is thus 

 vaguely described by Desvignes : — 



Head black; mouth, face and frontal orbits, flavous. Antennae setaceous, half length of body; 

 black, with scape flavous beneath. Thorax black with callosities before and beneath radix flavous. 

 Scutellum flavous. Abdomen narrower than thorax, black ; segments two to four and apex of first 

 flavous ; base and ape.'j of fourth sometimes fusco-ferrugineous ; iifth to seventh occasionally with a 

 faint dorsal pale spot on each. Legs black ; anterior femora flavidous at base and apex, hind ones 

 fulvous at base and extreme apex ; tibiae and tarsi pale fulvous, apex of hind tibiae black and hind 

 tarsi excepting their base fuscous. Wings with stigma fulvous ; tegulae flavidous ; radix and costa 

 ferrugineous ; areolet sub-triangular. Length, 8-9 mm. 



It would appear to be closely allied in its small size and maculate anus with the c? of/, intricaior, 

 Wesm., described by Holmgren in Verb. z.-b. Ges. 1878, p. 174, though undoubtedly distinct therefrom. 

 Desvignes drew his description from twenty examples taken at the same time and place, which are 

 now in the British Museum collection. 



Ichneumon nivcatus, Desv, loc. cit. 25, is a (f Cryptid, and Desvignes has himself labelled his types 

 in the British Museum "probably i'hy^adcnon arridins." 'I hey agree perfectly with Gravcnhorst's 

 description of that species.
