128 BRITISH ICHNEUMONS. [Canidiella 



gth September, iqio, I swept a female from reeds on the Suffolk coast at 

 SoLithwold ; and Newbery took another at Newport in the Isle of Wight 

 during igo8.

A black species with the areolet regular and distinctly petiolate, the 

 areola short and pentagonal, anterior legs red from near base of femora, 

 tegulae white, posterior tibiae entirely, their trochanterellus and apices 

 of femora fulvous. Length, 6^-6i mm. 



Agrees with the last species in the shape of areolet and areola, in the 

 centrally subexplanate abdomen and front pedal colour, but the posterior 

 legs are clear fulvous with coxae, base of trochanters, of the intermediate 

 and basal two-thirds of hind femora black, the antennae are longer and 

 apically more attenuate with apical joints strongly discreted, the petiole 

 is distinctly a little longer and less abruptly dilated centrally, the terebra 

 is slightly exserted and the size larger, 



Brisch ke ascribed this species, which had long stood in our list under 

 Lhniieria, to its correct genus on Prussian specimens in i88o; Grav. had 

 it from Nuremburg and Volhynia, but it seems rare in central Europe; 

 France (Gaulle) and taken as early as April in Belgium (Tosquinet). 

 With us it is very rare and I owe a knowledge of it to single females in 

 Piffard's Hertfordshire and Capron's Surrey collections.

Thorns. Opusc. Ent. xi. 1116. 



Head dull, coarsely and alutaceously punctate ; vertex somewhat broad 

 and not constricted behind the internally hardly emarginate eyes; clypeus 

 not basally discreted, with deeply impressed lateral foveae ; face distinctly 

 transverse, peristomium ample, cheeks elongate; mandibles stout, with 

 acute teeth. Antennae hardly longer than half body, with scape black. 

 Thorax subcylindrical, longer than high, punctate and dull ; mesopleural 

 speculum glittering; metathorax rugosel)- punctate, with indistinct areae; 

 areola elongate and apically incomplete, with no costulae. Scutellum 

 convex. Abdomen elongate, apically subclavate ; basal segment curved 

 and extending to trochanteral apex, with no lateral sulci ; postpctiole a 

 little longer than broad, hardly broader than but double length of petiole, 

 with no lateral scrobes; second segment finely and alutaceously punctate, 

 elongate; third quadrate, terebra not exserted. Legs somewhat slender, 

 with hind femora subincrassate and mainly black ; hind calcaria about 

 half length of metatarsi. Wings with tegulae pale; areolet wanting, 

 with the intercubital nervure di.stinctly longer than its distance from 

 second recurrent ; basal nervure continuous ; radial cell somewhat short 

 and not acutely angled centrally, with its apical abscissa but little the 

 longer; apex of discoidal cell rectangular below; nervellus oblique, 

 antefurcal, and strongly geniculate at its lower fourth. 



The abdominal shape allies this genus to Ctisiinin'a and our species is 

 somewhat like the male of C. morionclla, though more slender, with no 

 areolet and the eyes not at all emarginate. The' approximation of the
