126 BRITISH ICHNEUMONS. [Ccniuh^lla 



Genoa and Turin (Grav.) ; Lund, north and central Germany (Thorns.). 

 It has long been known as British, under the old genus Limneria, but 

 was correctly relegated to the present by Brischke, who found females in 

 Prussia, in 1880. Bignell says he has captured it at Bickleigh in Devon 

 about the middle of September and that he bred it there on 22nd June 

 from Pseudopterpna cytisaria, but I place none too much reliance upon this 

 Lepidopterous host. Capron found a full series about Shere in Surrey ; 

 Tuck both sexes at Tostock in Suffolk in June and October, iqoo ; Pif- 

 fard took females at Felden in Herts ; and I swept another on qth June, 

 1902, at Wicken in Cambs.

Black with the legs not broadly pale, the abdomen but little compressed 

 and thrice longer than the terebra ; hind legs with only the tibiae cen- 

 trally entirely, and basally a little, whitish. Length, 3^-5 mm. 



Thomson says his species is similar to his C. rostrata in the abdominal 

 conformation and terebral length but with the mouth not rostrately elon- 

 gated and the flagellum, as in C. exigua, slender with the flagellar joints 

 well discreted. He considered Gravenhorst's species distinct from that 

 of Holmgren, for which he proposed a new name, but I am of opinion 

 that they are forms of the same, both occurring with us and included in 

 the details of capture below, the latter differing mainly in having the 

 abdomen a little narrower with shorter terebra. Ratzeburg's C. siihcinctus 

 is now generally ascribed to Omorga borealis, on Thomson's somewhat 

 indefinite suggestion. The present is at once known from the last 

 species by its more slender form, longer terebra and entirely white- 

 banded hind tibiae, which latter are beneath black throughout in the 

 earlier one. The female of the present is at once known by the terebra 

 being no longer than its basal segment, but the males are difficult to 

 separate from those of the next species. 



The two original females were taken by Hope at Netley in Shropshire ; 

 it was found by Holmgren occasionally during July and August in Sweden, 

 by Brischke in Prussia and by Gaulle in France. Ratzeburg tells us 

 (Ichn. d. Forst. ii. 80-82) that Dahlbom bred this species from larvae of 

 Hypera polygom, which were feeding upon Siletie in Lund, on 8th August, 

 1837: but perhaps his species was not the present. In Britain it has 

 subsequently occurred at Eaton near Norwich in July (Bridg.); Wilson 

 Saunders took a female at Greenings in Surrey during July, 1872 ; Dalglish 

 another at Kings Cross in Arran in August, 1900 ; Capron possessed two 

 more from Shere; and I took a few of both sexes in 1900 at Southwold 

 cliff's on Heracleiim sphondvUum flowers on 26th July, in allotment gardens 

 at Aldeburgh in July, and Lakenheath and Brandon early in June, by 

 sweeping Mentha hirsiila in ditches at Foxhall in the middle of August ; 

 Miss Chawner has sent me a couple from the New Forest and both sexes 

 have occurred to me at Grovely Wood in Wilts at the end of June. It 

 also has been swept by me at Mablethorpe on the Lines, coast in the 

 middle of June, 1912,
