282 BRITISH ICHNEUMONS. [Spi/oaypius. 



testaceous ; hind femora and generally tibiae of $ basally castaneous or 

 ferrugineous, not white. Wings clouded, of ? with a darker cloud beneath 

 the stigma ; ^ areolet sub-quadrate and nervelet indicated ; tegulae and 

 radix black ; areolet only very slightly convergent above ; nervellus nearly 

 opposite, interce[)ted below the centre Length, 812 mm. 



C. grossus appears to differ only in the shorter and more numerous 

 antennal joints ; Schmiedeknecht, however, considers it distinct on 

 account of the sub-hyaline wings and shorter terebra. The colour and 

 conformation of the abdomen of grossus is very similar to that of 

 .S". adi/sli/s, but the head is more strongly declived behind the eyes, the 

 cheeks much longer and sub-compressed, the mesonotum sparsely punc- 

 tate, with the scutellar foveae deep and striolate, metathorax short and 

 basally smooth, the tibiae hardly spinulose, and the post-annellus a little 

 longer than the scape. 



The nearly complete coxal areae allies this species with Hoplocryptus^ 

 but the nearly rounded and mutic clypeus, short metathorax, and the con- 

 formation of the abdomen, will distinguish it ; the large spiracles, distinct 

 coxal areae and broad $ abdomen, resembling Idiolispa, will render it 

 distinct among its congeners. 



Stephens records this species as rare in June about London, and Dale 

 as very rare at Glanvilles Wootton in Dorset. On the Continent it has 

 been bred by van Vollenhoven from Lophyriis catoca/us, and by Brischke 

 from Z. pint and Psyche viciella ; the latter also reared it hyperparasitically 

 from a species of Exetasfes, which is a genus of the Tryphoninae (cf. 

 Mori. E.M.M. 1903, pp. 157-164).

Head black with white palpi, clypeus strongly discreted and epistoma 

 sub-prominent. Antennae bicoloured, centrally white in both sexes ; basal 

 flagellar joint four times longer than broad. Thorax and scutellum im- 

 maculate ; metathorax coarsely rugose, with l)oth transverse costae entire, 

 the basal being curved and the apical centrally straight ; apophyses want- 

 ing, spiracles small and ovate. Abdomen ovate, as broad as the thorax, 

 smooth ; three basal segments red, the following black ; with white fasciae, 

 obsolete or wanting in $, on the sixth and seventh; basal segment 

 strongly curved laterally, dorsally flat and nitidulous, with hardly visible 

 spiracles ; post-petiole shining, canaliculate and rather longer than broad ; 

 terebra less than half the length of the abdomen. Legs somewhat slender, 

 pale red ; apices of the hind tibiae and femora black, their tarsi white 

 with black claws ; ^ diff'ers in having the anterior coxae and trochanters 

 white, hind coxae black, with pale apices and the hind trochanters red 

 with a black dorsal spot. Wings somewhat clouded ; areolet sub-quadrate 

 and nervelet wanting ; radix testaceous, tegulae infuscate or red. Length, 

 10^ mm. 



The specimens of this species in the Bridgman collection in the 

 Norwich Museum are very similar to those of S. cimbicis and G. ortiali/s, 

 but the antennae of the c? are centrally white-banded, and the ? has the
