On some No///// African Ichneumonidae. 



basally broad aud apically truncate, closely punctate and not disereted 

 from the similarly punctate face ; mandibles stout and obtusely bi- 

 dentate apically, teeth nigrescent ; both maxillary and labial palpi 

 testaceous, with cylindrical joints ; eyes internally parallel and not 

 emarginate ; frous sulcate from ocelli to the superiorly elevated 

 scrobes. Antennae elongate, setaceous, slender and immaculate. 

 Thorax stout, dull and closely punctate ; uotauli deeply impressed, 

 sternauli wanting ; mesopleural speculum f oveate ; metathorax without 

 even supracoxal cariuae, impressed at the slightly elongate spiracles, 

 its disc longitudinally subsulcate. Scutellum and postscutellum 

 convex, deeply punctate, with only basal carinae. Abdomen glittering 

 aud subglabrous, with two first segments deplanate and remainder 

 subcompressed ; basal segment straight, slightly explauate throughout, 

 twice and a half as long as apically broad and centrally constricted 

 beyond the somewhat prominent spiracles ; central segments in- 

 definitely black-lined laterally ; hypopygium large and cultriform ; 

 terebra hardly exserted. Legs slender, the hind ones elongate, with 

 apices of their tibiae infuscate ; coxae finely punctate ; claws distinctly 

 and shortly pectinate. Wings ample ; lower basal uervure but slightly 

 postf urcal ; internal cubital entire and broadly fenestrate at its apical 

 third ; areolet rhomboidal and corueously petiolate, emitting the semi- 

 fenestrate recurrent distinctly before its centre ; nervellus elougately 

 postfurcal, emitting spurious uervure from its upper third. Length, 

 11 mm. The produced clypeus places this species in Tegona (cf. lib. 

 cit., fig. Ixii), though the cheeks are much shorter than the basal 

 breadth of the mandibles. 



The type was discovered by W. E. Jones at Mfongosi in Zululand 

 during April, 1916. 



TRIBE SK1APODES, trihit* nova. 



The characters are those of the genus. So remarkable is the con- 

 formation of the following species that I find myself reluctantly 

 compelled to erect for its reception a new Tribe, agreeing in its 

 abdominal structure to a limited extent with the Banchides,a,s grouped 

 by me (Eevl'j,. Ichn. iv, 1015, p. 135), but with totally different and 

 unique neuratiou. The Skiapodes is at once known from the whole 

 remainder of the Ichueumouidae by its semicircularly excised occiput, 

 the sublinear disposition of the ocelli, the bicarinate frous, minute and 

 subquadrate mandibles, which are (as in the Braconidous family 

 Alysiidae) porrect and not apically touching inter se, and by the 

 unique structure of both uervures, which most closely, perhaps,
