Hetnileles.] BRITISH ICHNEUMONS. 1 35 



On the Continent it is common upon plants infested with Aphides and 

 Syrphid larvae ; it is recorded by various authors as bred from Tinea 

 biselliella, T. crinella, Cokflphora ni}:;ncella, Chrysocorys festaliella, Pieris 

 bnxssicae and Acronycta psi. It is by no means uncommon with us, and is 

 usually found on house-windows in June and July. Common in Norfolk 

 (Bridgman) ; Stonehouse in Devon (Bignell) ; Hastings district (List); 

 Maldon in Essex (Fitch) ; I possess specimens from Capron's and Piffard's 

 collections, found in June; Miss Chawner has taken it in the New Forest 

 and Elliott at Peterborough, early in July. It has occurred to me on 

 windows at Butley, and Monks' Soham House, in Suffolk. The type 

 form was bred hy[)erparasitically from Cucidlia argeniea by Brischke, who 

 raised his male variety from larvae of Ocneria dispar through a species of 

 Microgasier, and from Ilarpyia bifida through a Faniscus cocoon.

Head with the palpi, labrum and mandibles centrally, white ; vertex 

 somewhat broad and not contracted behind the eyes, cheeks buccate ; 

 clypeus discreted, short and apically truncate with two small central teeth ; 

 mandibles not tuberculate ; face of $ with white pubescence. Antennae 

 slender, shorter than the body, with the second flagellar joint not shorter 

 than the first ; of ^ elongate and a little attenuate with the scape white 

 beneath, of $ filiform with the scape testaceous beneath. Thorax sub- 

 cylindrical ; mesonotum densely and very finely pubescent and dull, with 

 the notauli obsolete ; metathorax somewhat smooth, with complete areae 

 and fine costae ; areola almost pentagonal, basally sub-acuminate and 

 apically truncate; petiolar area discreted, a[)ophyses wanting. Abdomen 

 stout, sub-fusiform, of ? apically compressed and as broad as the thorax ; 

 black, 9 with the second segment, $, with most of the incisures, casta- 

 neous ; basal segment basally bicarinate and closely punctate, apically 

 finely aciculate, gradually explanate throughout ; post-petiole very broad, 

 sub-quadrate, strongly convex, twice broader and slightly longer than the 

 basally contracted petiole ; terebra as long as the abdomen, black, with 

 the very stout and lanceolate and apically truncate spicula, and the sub- 

 exserted $ valvulae, red. Legs normal, pale red ; anterior co.xae whitish, 

 intermediate sometimes red, both pairs often basally black, as are the hind 

 coxae ; all the trochanters entirely white ; hind tarsi and pait of their 

 tibiae infuscate, the latter being basally white. Wings hardly clouded ; 

 stigma infuscate, and emitting the a[Mcally straight radial nervure from 

 beyond its centre ; tegulae, radix and base of stigma while ; areolet ex- 

 ternally obsolete ; nervellus evidently antefurcal. Length, 5-6 mm. 



It differs from all the subsecjuent females in its broader and more convex 

 basal segment, and in its longer and lanceolate terebra. It is similar to 

 H. varicoxis in the white basal hind tibial band, by which it is distinguished 

 from Cecidonomus inimicus. The latter shares in common with it the 

 dull frons and mesonotum, complete metathoracic areae, broad and finely 

 striolate post-petiole, etc. 



It is said to occur in June, and has been found by Bridgman at Earl- 

 ham, near Norwich, in July. I possess three males and one female of
