NataL: Durban ¢: Jan. 18, 1906 (G. F. Leigh); 
RuwopEsiIA: Mashonaland, Salisbury 2 (G@. Marshull) ; 
Melsetter, Gazaland 2 (S. A. Neave). 
It is with considerable hesitation that I assign the 
single { specimen from Durban in Natal to the above 
form. If it is not the ¢ of £. clotho, but previously un- 
described, it may stand as Z. leighi mihi. 
¢. Black with an iridescent blue sheen on the abdomen; head, 
thorax and abdomen covered all over with a more or less sparsely 
set clothing of soft erect cinereous hairs, tibial calcaria of the 
posterior pair of legs white, anal spines black ; the base of the 
mandibles, upwardly convergent short stripes on the sides of the 
clypeus, the posterior margin of the pronotum, lateral transverse 
short lines one on each side on the scutellum, a medial short similar 
line on the postscutellum, and the apical margins of the 2nd, 3rd 
and 4th abdominal segments pale dull yellow ; of the last-mentioned 
markings that on the 2nd segment is deeply, on the 3rd slightly 
emarginate laterally, the marking on the 4th segment is a simple 
transverse even band. Head, pro- and mesonotum, scutellum, 
postscutellum and abdomen above with sparsely scattered fine and 
very shallow punctures ; median segment regularly and more closely 
punctured above, smooth and impunctate on its posterior face. 
Head flat, not as broad as the thorax ; mandibles acute at apex, 
clypeus strongly convex, face in front raised, tuberculous between 
the antennae ; these latter filiform opaque, eyes deeply emarginate 
above on their inner margins, ocelli prominent. Thorax oval; 
median segment truncate and concave posteriorly ; wings fusco- 
hyaline with a bronzy, in some lights a purplish effulgence, forewing 
with two cubital cells and two recurrent nervures, legs slender 
unarmed. Abdomen: elongate slender, basal segment subpetiolate, 
nodose towards apex, a strong constriction between it and the 2nd 
segment, both above and below. 
Length ¢ 17. Exp. 28 mm. 
The above-described ~# resembles more or less the 
males of /. villosa, fasciatella and godefredi, but can be 
distinguished from these three forms by the paucity and 
narrowness of the yellow markings on the abdomen, by 
the darker colour of the wings, and by the shape of the 
median segment which has its posterior face much more 
deeply concave.
