152 BRITISH ICHNEUMONS. 



As far as I am aware, its inclusion in our list rests solely upon Stephens' 

 record (including (iravenhorst's 3, which is Spilichneumon limnophilus^ 

 Thorns., and has nothing in common with the present species), from near 

 London, taken very rarely. On the Continent, it would appear to be of 

 extreme rarity ; (iravenhorst's original sipecimen was from Turin, in Pied- 

 mont ; Berthoumieu omits this, but says " Russie meridionale " ; Grav. 

 calls Turin, " Tauria," and possibly Berth, mistook this to refer to Taurida, 

 in southern Russia. I know of no other localities.

Head distinctly narrowed behind eyes, black ; ? with internal orbits 

 and often centre of face rufescent ; S face and clypeus entirely or laterally 

 white. Antennae of ? slender, setaceous, not thickened centrally, some- 

 what attenuate at apex, the eighth joint quadrate, white-banded or tri- 

 coloured ; S with scape flavous, and flagellum piceous, beneath. Thorax 

 black, that of $ with white lines beneath the radix ; areola sub-quadrate, 

 somewhat transverse in S, apically emarginate. Scutellum white, some- 

 what strongly convex. Abdomen of $ sub-cylindrical, of $ elliptic-oval ; 

 black, segments two and three, often apex of first and base of fourth, red, 

 fourth and sometimes part of third in S black ; sixth, seventh, and often 

 fifth minutely, white-marked, these anal marks often wanting in $ ; post- 

 petiole aciculate ; gastrocaeli small, thyridii elongate and very distinct, the 

 intervening space sub-striate in S , coarsely punctate in $ ; terebra slightly 

 exserted. Legs black ; $ with anterior femora, tibiae and tarsi, and hind 

 ones basally, red ; $ with anterior tibiae and tarsi fulvous, hind ones black 

 towards the apex ; hind coxae with fine puncturation. Wings a little 

 clouded; stigma fulvous, tegulae dark. Length, 7-10 mm. 



The $ has the flagellum slender, setaceous, basally entirely or beneath 

 red ; anterior femora entirely red ; the $ is very like that of /. graci/icornis, 

 but the thorax is shorter and more strongly convex, the second flagellar 

 joint longer than broad, the thyridii are a little smaller than the intervening 

 space, and the apex of the anterior metatarsi has an acute tubercle on its 

 inner side. 



The 5 is also very like that of /. gracilicornis, which, however, has the 

 femora more slender and much attenuate apically ; the gastrocaeli large 

 and the mark on fifth segment is larger than the following, but always 

 smaller in /. raptorius. 



From /. exie?isr>rius, and other allied species with red tibiae, it may 

 be told by its sub-quadrate areola, more convex scutellum and apically 

 attenuate antennae. It is like /. insidiosus, but always smaller, with the 

 scutellum in both sexes more elevated and convex, the petiole bicarinate, 

 the areola of S shorter, the posterior coxae of $ much more finely punc- 

 tured beneath, apex of antennae more tapering. 



From /. captorius, Thom., which it most resembles, it differs in the 

 rather more slender legs and antennae, the anterior femora are entirely
