Holotype $, Rhodesia: Bulawayo, i.xii.1924 (R. H. R. Stevenson) (NM, 

 Bulawayo) . 



L. fallax sp. n. is most closely related to L. varicollis Cameron, but the carinae 

 on the pronotum are weak, especially the discal one is notably lower (Text-fig. 

 129), and the vertex is unusually convex. The weaker carinae of pronotum remind 

 one of L. africana Cameron; the latter, however, has not the premarginal carina 

 angulate, has the dorsellum bare and subbidentate, the ovipositor still shorter. 



Leucospis elegans Klug 

 (Text-figs 130-133) 



Leucospis elegans Klug, 1834 : Dec. 4 : [26], pi. 37, fig. 3, §. Holotype $, 'Arabia Felix' 

 (MNHU, Berlin) [examined]. 



The holotype was redescribed by Westwood (1839 : 248-249) and by Schletterer 

 (1890 : 217-219) but neither of them knew any other material. 



The species can be recognized by the unusually coarse puncturation of the hind 

 femur and by the relatively rich yellow markings. The hind coxa is very broad 

 and, as in L. insularis Kirby, has the inner side of dorsal edge sharply carinate, the 

 margin of carina narrowly translucent. Pale yellow are the scapes, a broad band 

 on pronotum, most of scutellum (often except narrow base), then broadly dorsal 

 edge of hind coxa, hind femur except disc near apex, all tibiae dorsally, a broad 

 band on the fifth tergite posteriorly, a narrow band on the fourth tergite, two large 

 triangular maculae on the first tergite and apex of the gaster; sometimes also sides 

 of the mesoscutum, dorsellum, part of propodeum, upper mesepisternum and 

 metapleurum are yellow. The similar L. insularis has the head less transverse, 

 the pronotal carinae much lower, the hind femur much narrower, apart from the 

 reduced yellow markings and unusually long pubescence. Female 7-11 mm. 



<§ (until now undescribed) . 6'5-8'0 mm. Colour as in O. including broad yellow band on 

 pronotum delimited by angulate premarginal carina and not extending below shoulders ; gaster 

 with dorsal macula on first tergite, on carapace a narrow band (expanding forwards in middle) 

 before broadest place, broad second band behind broadest place and extensive subapical macula 

 indented above. Form of gaster shown in Text-figs 132, 133. First tergite between deep but 

 short basal fovea and lateral keel punctured, dorsum rather flat; second tergite very short; 

 third tergite separated from carapace only below lateral keel, hind margin of its epipleurum 

 almost straight. Hind corners of carapace slightly jutting out, auricle-like; epipygium with 

 transverse depression moderately deep. Sternites of medium breadth; third to fifth sternites 

 very slightly longer than broad; the sixth slightly more apparently so, its sublaminate loose 

 hind margin arcuately produced; last sternite concave at base, flat at apex which is truncate 

 with rounded corners. 



Biology. Host unknown. Species probably confined to arid regions. 

 Distribution. Egypt, Sudan, Saudi Arabia, Pakistan.
