148 BRITISH ICHNEUMONS. [Hemiteies. 



Yorkshire ; and I have captured it at Aldeburgh, in July, on liouse-windows 

 at Oreat Bradley and Felixstowe, in June, and once attracted to artificial 

 light, in which its wings were scorched, at Sudbury, in 1900. Bignell has 

 captured it at Bickleigh in Devon, in Se[)tember, and it is j^robably very 

 common with us. On the Continent it is often found on house windows 

 from June to August, as well as frequenting jjlants affected by Aphides 

 and Syrphid larvae ; Taschenberg took eleven males on vine leaves in 

 early August, and adds that the coloration of the legs is variable. It has 

 been bred from Pieris brassicae and Limneria cocoons among the eggs of 

 Epeira diademata (Brischke), Fumea iiitermediella and Sokfiobia iri(]ueirella 

 (Bridg.-Fitch). Waterston took both sexes in St. Kilda, in June, 1905. 



30. sordipes, Grav. 



Hemiteies sordipes, Gr. I. E. ii. 798; Tasch. Zeits. Ges. Nat. 1S65, p. 131 ; Thorns. 

 O. E. X. 976; Schm. Term. Fiiz. 1897, p. 521, 9. 



Head with vertex broad and cheeks buccate ; frons very finely and 

 densely punctate and pubescent ; mandibles not geniculate. Antennae 

 very slender and nearly length of body, with scape excised and sub- 

 globose. Mesonotum densely pubescent throughout, mesosternum not 

 transverse ; metathoracic lateral costae wanting and the pleural nearly 

 contiguous with the spiracles. Abdomen black, petiolate and as broad as 

 thorax, with its anus sub-clavately compressed ; post-petiole sub-quadrate, 

 slightly constricted basally, longer and twice broader than the petiole ; 

 terebra as long as abdomen. Legs red, with coxae basally infuscate ; 

 femora and tibiae somewhat infuscate above. Wings hyaline, with no 

 trace of an areolet ; stigma piceous, radix and tegulae white ; nervellus 

 antefurcal. Length, 4-5 mm. 



Gravenhorst says this species is very like H. similis, but with body a 

 little more slender, the terebra longer and basal segment broader ; but 

 Taschenberg considered it so closely related to H. pictipes in form, sculp- 

 ture and, except of the legs, colour as to be little more than a variety of 

 that species. Thomson, on the other hand, places this species with 

 H. cyfiipinus in a section apart ; he says the flagellum is very thin indeed, 

 the segments are smooth and margined with olive colouring, epipleurae 

 not inflexed, epicnemia slender, and areolet hardly entire externally, 

 emitting the parallel nervure nearly from its centre. 



I have quite failed to recognize this female, which occurs on the Con- 

 tinent in Germany and Sweden. The only definite record I can find, 

 though it has for long stood in the British list, is Bridgnlan's, from Aylsham 

 in Norfolk, where it was bred from the galls of Cy/iips KoUari.

Black ; legs varied with red ; terebra shorter than the somewhat broad 

 basal segment. Length, 3-4 mm. 



So similar to the last-described species as to render details superfluous ; 

 therefrom it differs in having the antennae less slender and shorter than 

 the body, the flagellum filiform and slightly attenuate basally, the second 

 segment more strongly transverse, the second to the seventh becoming
