126 BRITISH ICHNEUMONS. [Hemiteles. 



segment, usually pale incisures, the longer ? three basal flagellar joints 

 and the concealed $ anal styles. 



Bridgman bred this species from Micrci^aste?- cocoons taken in the 

 neighbourhood of Norwich ; he adds Mousehold in Norfolk as the locality 

 and says it has been bred from the cocoons of Apanteles conjes(u%. Hyper- 

 parasitic, through Apnnfe/es not/ii/s, on a grass-feeding larva found at 

 Oreslon in Devon, bred 15th August (Bignell) ; hyperparasitic, through 

 Apanteles diffici/is, on larva of Diloha caeriileocephala (Schni.). Both sexes 

 are represented in Capron's collection, probably taken about Shere ; Miss 

 Chawner has also bred both at I ,yndhurst ; and I have seen seven males, 

 bred with no females, from LithocoUelis brimiella at the end of April. 



Mr. E. R. Bankes has given me a $ and two $ $ of this species bred, 

 together with three $ $ and two $ $ of Elas7nus (1) flabellatus, Fonsc, 

 and two ? $ of some Pteromalid, from May loth to 20th, 1900 (a pair of 

 the E/asmi/s was in cop. at 7-30 a.m. on the nth; the $ Hemiteles 

 emerged on the 14th ; and the two Pteromalids, which have mon ill form 

 and clear flavous antennae with a black apical club, on the i6th). They 

 were bred from larvae of Lithocolletis Schreberella, collected on elm near 

 Salisbury, on 9th November, 1899; no Braconids emerged from these 

 hosts.

Hemiteles scabriculus. Thorns. O. E. x. 969 ; Schm. Term. Fiiz. 1897, p. 507, i ? . 



Black. Head with the cheeks sub-buccate and clypeus mutic. An- 

 tennae with the scape sub-globose and excised, and the second flagellar 

 joint longer than the -first ; of $, with the joints distinctly discreted, of $ 

 sub-filiform with the scape black. Pronotum with the central dorsal carina 

 short, and deeply foveate laterally ; mesonotum dull, pubescent and not 

 convex discally ; metathorax with two distinct transverse, but only obsolete 

 lateral longitudinal, costae ; basal and petiolar areae both triangular, areola 

 basally acuminate, spiracles nearly contiguous with the lateral costae. 

 Abdomen dull, with the sides and apices of the segments narrowly rufes- 

 cent, of $ mainly black ; post-petiole densely and very finely aciculate, 

 apically explanate with no carinae ; second segment very finely and trans- 

 versely aciculate ; terebra shorter than the first segment. Legs testaceous, 

 with the anterior trochanters flavidous and the posterior coxae, femora and 

 tarsi piceous ; of $ mainly black Wings not fasciated ; stigma infuscate, 

 emitting the radial nervure from its centre ; areolet internally entire ; 

 nervellus intercepted and obviously antefurcal. Length, 4-6 mm. 



Similar in its antefurcal nervellus, etc., to H. infirnius, varitarsus and 

 conformis, but at once distinguished from them by its triangular basal area 

 and filiform $ flagellum. 



Thomson considerably qualifies his description by adding that it is 

 possibly the same species as H. Iristator, Grav. 



This species has hitherto only been elsewhere found in Sweden. 

 Bridgman records (Trans. Ent. Soc. 1886, p. 340) a female from the 

 neighbourhood of Norwich, which was named by Professor Thomson, 

 and he says he took it at Eaton in Norfolk, in July. I possess three 

 females captured by Pififard at Felden in Herts., and two by Capron at 

 Shere in Surrey.
