164 BRITISH ICHNEUMONS. [Hemtteks. 



distinct, areola sub-triangular and hardly longer than broad, basal area 

 transverse, triangular and apically sub-spinose laterally. Abdomen elon- 

 gate-ovate, anus sub-compressed and membranaceous ; second, apex of 

 first and disc of third segments red ; basal segment very finely aciculate, 

 twice longer than its apical breadth, which is thrice the basal, second 

 segment sub-transverse ; terebra deflexed and ratlier longer than half the 

 abdomen. Legs normal, red with hind trochanters mainly black and the 

 tarsi partly infuscate. Wings with stigma black, tegulae pale piceous ; 

 areolet with outer nervure wanting ; nervellus antefurcal and intercepted 

 below centre. Length, 5 mm. 



It is very like H. ridibiindus, Grav., but the head and thorax are 

 smoother and more shining, the coxae are red and the stigma is not 

 basally white. I find no pertinent distinction between the above description 

 and that of H. dedpie?is, Grav., and am strongly of opinion that these 

 species are synonymous. 



This unique female was bred by W, H. B. Fletcher from a cocoon 

 found at Chesil Beach, April 24th, 1884.

Head with the centre of the mandibles badious and the clypeus discreted. 

 Antennae slender, shorter than the body with the joints cylindrical. 

 Thorax black ; metathorax finely alutaceous, of $> oblique ; areola longer 

 than broad, with the costae not prominent and the petiolar area distinctly 

 discreted. Abdomen ovate, as broad as thorax ; black, with three central 

 segments and apex of the first red, laterally (and the fourth apically) infus- 

 cate ; ? with segments five to seven apically whitish, $ with fifth broadly 

 red longitudinally in the centre ; basal segment narrow and thrice longer 

 than broad, very slightly dilated apically, aciculate, obsoletely bicarinate 

 and canaliculate, with no tubercles ; second segment closely and finely 

 punctate, of $ narrow and elongate, gradually explanate and usually 

 laterally infuscate ; terebra rather longer than half abdomen. Legs 

 slender, red ; hind tarsi and apices of their tibiae infuscate ; $ with 

 trochanters and often coxae flavidous. Wings normal, slightly clouded 

 with stigma and costa black, radix and tegulae stramineous. Length, 

 6 mm. 



Taken by sweeping in the Duryard estate, near Exeter, in August 

 (Parfitt). It is only known on the Continent from Germany, where 

 JBrischke bred it from Lipara lucens. [Laboulbene records H. liparae, 

 Gir., as a parasite on Lipara iof?ientosa, in Annido stems. Ann. Soc. Fr. 

 1877, p. 401.]

A slender, black species. Head sub-triangular and somewhat narrowed 

 behind the eyes ; vertex broadish, clypeus produced, frons dull. Antennae 

 nearly as long as the body, filiform, with the scape globose and sometimes 

 red. Mesonotum somewhat dull, with elongate notauli ; metathorax sub- 

 rugosely punctate with distinct costae ; areola emitting the costulae from
