Homocidus | BRITISH ICHNEUMONS. 105 


It appears uncommon with us, but is probably only overlooked ; I have 
half a dozen specimens taken at such diverse localities as Longniddry 
Links, near Edinburgh, on zs5th August, 1898 (Evans); Malvern, 
Worcestershire (Gorham) ; Greenings (W. Saunders), and Shere (Capron, 
the typical males), in Surrey; and Ryde, Isle of Wight, 17th August, 1903 
(Morley). Its distribution will probably be greatly extended upon in- 
vestigation; and I am strongly of opinion that Aassus frenator, Desv. 
(Trans. Ent. Soc. 1862, p. 218), represented by a single headless male in 
the National Collection, is referable to it, rather than to H. ornatus, with 
which I synonymised it in 1905, despite the discrepancies of his primitive 
description. 
19. reflexus, Morl. 
Homoporus reflexus, Morl. Trans. Ent. Soc. 1905, p. 423, ?. 
Head dull and black; vertex not broad, posteriorly entire; frons cen- 
trally distinctly sulcate; face somewhat broader apically with the epistoma 
a little convex and quadrately pale in the centre; clypeus testaceous, 
deplanate, not laterally elevated, but with the apical margin entire and 
strongly reflexed; palpi and base of the stout mandibles flavescent. An- 
tennae longer than head and thorax, and entirely black. Thorax black 
with a hamate line and a dot before with a longitudinal callosity beneath 
the front wings, and the basal margin of the mesopleurae flavous; meta- 
thorax evenly scabriculous throughout with minute circular spiracles, and 
the apex centrally substrigose between two broad and shallow foveae. 
Scutellum subdeplanate with the apical margin, together with that of the 
postscutellum, transversely flavidous. Abdomen elongate-oval, immacu- 
late, finely alutaceous and dull, becoming nitidulous towards the slightly 
compressed anus; basal segment quadrate, laterally margined, with no 
carinae; the following transverse with the second obsoletely aciculate at 
its base; terebra reflexed. Legs red; the hind tibiae becoming gradually 
nigrescent from centre to apex, their tarsi entirely and the anterior at the 
apex, black. Wings hyaline, with tegulae white, stigma testaceous ; 
areolet subpetiolate; nervellus a little postfurcal and intercepted only 
slightly below its centre. Length, 64mm. 6 unknown. 
From all the other members of the genus bearing an areolet and no 
petiolar carinae, the present is very distinct in its apically entire and 
strongly reflexed clypeus. The alutaceous abdomen, thoracic colouration 
and general conformation ally it with HZ. crassicrus, Thoms., from which 
it is sufficiently distinct in its clypeal and vertical structure, sulcate frons, 
apically explanate face, the antennae entirely and scutellum laterally im- 
maculate, the interception of the nervellus, acutely margined basal seg- 
ment, the dull testaceous hind tibiae and abdominal plica. 
The type, which isin my collection, was taken by Dr. Capron, probably 
at Shere in Surrey; I also took it in a greenhouse in a Ryde garden, in 
Isle of Wight, on 11th August, 1902. 
Holmgren describes the hind tibiae of his Bassus strigator as rufescent 
with their apices infuscate; it is consequently very distinct from that of 
Fabricius and Gravenhorst; I know nothing so likely to be synonymous 
with it as the present species, though he goes no further than to tell us 
that the clypeus is stramineous and apically subemarginate; Thomson 
thought it possibly referable to 2B. ruficornis, Holmgr.
