OH some South African Ichneumonidae. 209 



centre ; <$ valvulae exserted, terebra straight and as long as abdomen 

 except first segment. Legs normal and not stout ; claws small, 

 calcaria short. Wings fulvescent hyaline, of <$ subiuf umate ; uervelet 

 Avanting; basal uervure continuous; areolet of normal size, sub- 

 quadrate, emitting the straight recurrent uervure from slightly 

 before its centre. Length, (?, 12 mm. The clypeal structure is 

 remarkable. 



Both sexes occurred at Mfongosi in Zululaud to W. E. Jones in 

 May, 1916. 



MESOSTENUS OCTANS, sp. nov. 



9 only. A somewhat slender, brick-red, dull species with the head, 

 antennae, apical half of abdomen, hind coxae, femora and two apical 

 joints of their tarsi, black ; labrum, vertical orbits, flagellar band, 

 apices of third and fourth and seventh segments narrowly, with 

 whole of the large and prominent eighth, and the three central hind 

 tarsal joints, white. Clypeus apically depressed and truncate ; uotauli 

 deeply impressed ; both metanotal transcarinae distinct, its petiolar 

 area striate ; basal segment stout, shagreened and only double as 

 long as its apical breadth ; terebra one-third of abdomen ; areolet 

 small and quadrate, emitting recurrent nervure before its centre ; 

 uervelet wanting, upper basal nervure postfurcal. Length, 12 mm. 

 -The coloration is distinctive. 



Taken with the last species at Mfongosi in Zululaud by W. E. 

 Jones.

Areolet small and quadrate, emitting recurrent nervure from its 

 centre. 



A female has been taken at Mfougosi in Zululaud by Jones during

Essential Characters. Metathoracic spiracles circular ; areolet 

 wanting ; clypeus neither reflexed nor apically depressed ; meso- 

 sternum not laterally spinate ; abdomen not metallic. The following 

 species is sufficiently congruous with E. liitea, Cam. (= P. ocularia, 

 Mori.), to allow of its inclusion in this somewhat anomalous genus, 

 though the upper basal nervure is distinctly a little autefurcal.
