144 MR. CLAUDE MORLEY ON AFRICAN 



of mesonotum svilcate and strongly elevated ; metanotum punc- 

 tate, with the dentiparal areae aciculate and areola liexagonally 

 quadrate, emitting strong costulsB from its centre. Scutellum 

 subquadrate, deplanate, elevated from base to the truncate apex, 

 laterally margined throughout, and much higher than metanotum. 

 Abdomen dull and closely punctate with the postj^etiole, second 

 segment to near its npex and the third to centre, longitudinally 

 striate ; gastrocot'li deeply impressed. Areolet triangular, almost 

 broader than high, coalescent above. Length, 11 mm. c? only. — 

 Doubtless this species were more correctly placed (on account of 

 its distinctively striate basal segments, the apices of which may 

 be said to be slightly produced laterally) in one of the more 

 typically Joppid genera, though its facies are sufficiently 

 analogons with the present one. — A single male was captured 

 at Chagwe in the Mabira Forest at some 3500 feet during the 

 middle of Jnly 1911, in Uganda. 



Tribe Ichneumonides. 

 Subtribe Oxypygini. 



Lagenesta. 



Head large and not strongly constricted posteriorly ; occiput 

 margined ; labrum strongly prominent, clypeus apically truncate ; 

 mandibles bidentate, the upper tooth the longer. Antenna? stout, 

 dilated beyond their centi'e. Metanotum transversely pinictate, 

 with no distinct ai'ete ; petiolar region transversely carinate below 

 its centre. Scutellum deplanate and not laterally carinate. 

 Abdomen neither punctate nor striate, with sides of segments 

 not angularly prominent apically ; apical third of petiole broadly 

 dilated ; gasti'occeli large and stoutly striate, but not deeply 

 impressed; ventral plica strong on second and third, weak on 

 foui'th and fifth, segments. Legs stout with tarsal joints spinose, 

 explanate and basally constricted ; hind femora extending to 

 fourth segment. Areolet lai'ge, pentagonal, and broad above, 

 emitting recurrent nervure from its centre ; radial nervure 

 apically reflexed. 



The above are the characters assigned to this genus by Cameron, 

 at the time of its erection (Ann. Nat. Hist, vii, 1901, p. 376) ; 

 but they are entirely di'awn from the female of one species, of 

 which he knew the male later (lib. cit. xi. 1903, p. 185) and the 

 only other published species four years afterwards (Zeits. Hym. u. 

 Dipt. V. 1905, p. 86, $ ), These are all from the Hills of northei^n 

 India, whence I have seen a third kind * ; and have no doubt 



* LaGEXESTA MOJJITOR, sp. 11. 



A cylindrical, brick-ved and cyaneous-black species, with infuniate wing-s. Head 

 cubical and broader than thorax, with the froiis to ocelli and mandibular apices 

 alone black ; occiput strongly margined ; vertex centrally rugose, laterally smooth 

 and behind the eyes strongly elevated into stout and obtuse spines ; fvons rugose 

 and centrally produced into a stout spine between the scrobes; temples longer than
