BRITISH ICHNEUMONS. 



punctate post-petiole, smaller gastrocaeli, more nitidulous hind coxae and 

 in the white-marked fifth segment ; the antenna! carinae of the 6 are very 

 distinct. 



Mr. W. Evans took one male, at Luffness Links, in INIidlothian, on June 

 19th, 1898, in circumstances similar to those under which Wesmael found 

 it on the sandhills, at Ostend, which, with one by Davies, in Cornwall, are 

 the only British examples. On the Continent it is only recorded from 

 France and Belgium, and has not been bred.

9 . Head black, rarely two narrow vertical dots white ; the mouth 

 parts red. Antennae filiform throughout, blackish ; the first five flagellar 

 joints apically red and the central ones white above. Thorax entirely 

 black ; metanotum with complete upper areae, of which the areola is 

 semi-oval and apically emarginate. Scutellum a little convex, castaneous. 

 Abdomen black ; segments two and three with apical, and often lateral, 

 margins rufescent ; sixth and seventh entirely white; petiole distinctly 

 bicarinate between the spiracles, post-petiole centrally aciculate ; second 

 segment rugulosely aciculate between the gastrocaeli ; terebra stout, only 

 slightly exserted. Legs as in $; hind coxae shining, punctate, with no 

 scopulae. 



c? . Head black ; palpi, mandibles and labrum stramineous ; clypeus, 

 face, frontal and external orbits whitish. Antennae black ; scape stra- 

 mineous, and flagellum ferrugineous, beneath ; not pale-banded. Thorax 

 black, pronotum and usual marks at radix white ; sculpture of metanotum 

 as in 9 • Scutellum a little convex, laterally whitish-flavous. Abdomen 

 black, with a mark at the apical angles of first segment usually pale ; the 

 second and third with incisures red, the sixth broadly, and seventh entirely, 

 white ; sculpture as in $ . Legs blackish ; anterior with femora internally, 

 and tibiae entirely, red ; hind femora narrowly red before the base. 

 Length, 8-10 mm. 



This varies less than the preceding species in the coloration of the legs, 

 which, nevertheless, is far from constant ; in the $ all the tibiae are some- 

 times very dark red, or the femora and tibiae may be red with the hind 

 ones apically black, which form is /. leucopjgns, Grav. ; or all the femora 

 and tibiae entirely red ; the anterior tarsi are usually ferrugineous, the hind 

 ones black ; the ? sometimes has the scutellum black, or only its apex 

 castaneous, the frontal orbits, pronotum and post-scutellum are occasionally 

 castaneous also (var. rn/ains, Berth.). 



From M. saiuratorms and Iniiiacu/aiorius, it may be known by the pale 

 stigma and frontal orbits. The second segment has a little lateral fold 

 before the spiracles ; the epicnemiae are entire ; the nervulus post-furcal. 



It may at once be distinguished from the species described by Thomson 

 in the Annales by the central area of the post-petiole and base of second 

 segment being striolate, by the $ bi maculate and the 9 castaneous scu- 

 tellum, in which last respect it resembles Barichieumon artalor, but that 

 species, among other divergences, has the post-petiole centrally punctate.
