ETHA CASTANEA, sp. nov. 



? only. A stoiit, finely punctate aiid hardly shining species, 

 castaneous with that colour indefinitely merging into black upon the 

 face, sternum, coxae, hind trochaiiters and anus ; didymate dots on 

 both the face and clypeus, the whole labrum and palpi, a central band 

 of the black flagellum, lines before and callosities beneath the radices, 

 apical two-thirds of the scutellum, the second and thii'd hind tarsal 

 joints, anterior trochanters and part of their coxae, white. Head 

 finely punctate and not posteriorly constricted ; face deplanate and 

 discreted from the strongly transverse and apically subconcave 

 clypeus ; mandibles stout and not large, with their lower tooth 

 distinctly a little the longer ; cheeks short and punctate. Antennae 

 elongate, filiform and slender, as long as body, with the scape red and 

 discally infuscate. Thorax stout and subcylindrical, with the entire 

 notauli crenula.te and the narrow sternauli inflexed ; metanotum 

 evenly declivous, basally shagreened, trans-strigose throughout beyond 

 the centrally evanescent basal carina, the apical with both apophyses 

 and basal ai-ea wanting ; spiracles linear. Abdomen elongate-fusiform ; 

 basal segment dull and very finely coriaceous, the postpetiole deplanate 

 with sparse and distinct punctures ; thyridii basal and not broad ; 

 terebra nearly as long as abdomen. Legs elongate and not slender, 

 with claws simple ; front tibiae paler, strongly iutumescent and basally 

 constricted. Wings ample and hyaline ; areolet pentagonal, small 

 and laterally parallel- sided ; discoidal cell narrow and also of equal 

 breadth throughout, apically obtuse below. Length, 15 mm. I 

 consider this female to belong to Etha, since it agrees therewith in all 

 its characteristics but the strongly inflated front tibiae, which exactly 

 resemble those of Xyloplirumis and Nyxeopliilus, Forster. 



It was captured at Durban in Natal by W. Hay garth during 

 Februarv, 1914.
