BRITISH ICHNEUMONS. 287 



Coleophora, at Ipswich, in 1895, ^"^ ^o take another on the wing, among 

 undergrowth, in Bentley Woods, in the middle of June, 1902 ; and Mr. A. 

 H. Hamm has also taken it, probably about Oxford. On the Continent 

 it is not a rare species, and has there been bred from the case of Psyche 

 viciella and from a species of Coleophora. Professor Ratzeburg remarks 

 upon the resemblance of its elongate form, and especially that of the meta- 

 thorax, with the long and slender case of its host. 



NEMATOMICRUS, Wesmael 



Wesm. Nouv. Mem. Ac. Brux. 1844, p. 166. 



Body linear, smooth and nitidulous. Cheeks and face short, the latter 

 strongly protuberant and, viewed laterally, forming a right angle with the 

 very fiat frons. Antennae inserted low on frons. Thorax dorsally de- 

 planate ; mesosternum sub-longitudinally excavate ; metathorax gradually 

 declived from base to the slightly produced apex, its areae obsolete and 

 indeterminate, with central longitudinal costae fine. Scutellum very fiat, 

 sub-obsolete. Abdomen with petiole not laterally marginate ; second 

 segment with two central foveae at the base. Hind femora of ? short 

 and stout. Areolet entire ; nervellus antefurcal, intercepted below the 

 middle. 



Wesmael tells us that the only species of this genus, excepting the acute 

 anus of the $ , has much the form of Alomyia. 



I. tenellus, Wesm. 



Nematoinicriis tenellits, Wesm. Nouv. M^m. Ac. Brux. 1844, p. 179; Thoms. O. E. 

 XV. 1613; Berth. Ann. Soc. Yx. 1896, p. 387, i ?. 



Head black ; palpi white, frontal orbits flavous ; mandibles and clypeus 

 of $ fulvous, of $ as well as the face and sometimes apices of the cheeks, 

 flavous. Antennae dull red, basally piceous ; of $ incrassate and some- 

 what short. Thorax black, with an elongate callosity before, and a sub- 

 obsolete one beneath, the radix flavous. Abdomen black, with apical 

 margins of the six apical segments centrally red and laterally, at least in $ , 

 fiavescent ; ventral surface mainly flavidous ; terebra very shortly exserted, 

 its valvulae broad and apically sub-acute. Legs pale red ; hind coxae and 

 trochanters basally, their femora and tibiae in part, and the tarsi, black ; 

 anterior coxae and trochanters of $ white ; calcaria short and red. 

 Tegulae and radix flavous ; stigma rufescent. Length, 6 mm. 



This distinct species was brought forward as British by Marshall, in his 

 1870 catalogue, but I know of no indigenous records, though there is one 

 female in Mr. Alfred Beaumont's collection, which he took at Colwyn on 

 the 22nd of August, 1 89 1. On the Continent it occurs in Denmark, 

 Belgium, etc., but has not yet been bred. 



MELANOMICRUS, Morley.

Head hardly narrowed behind the eyes ; frons totally glabrous ; vertex 

 broad and laterally a little protuberant ; epistoma tuberculiform ; clypeus 

 not discreted, apically mutic and broadly rounded ; cheeks normal ;
