108 Z. BOUCEK 



parts of Africa) the first tooth is distinctly smaller than the following tooth, whilst 

 in some other specimens, mostly from Central, West and East Africa the basal 

 tooth of hind femur is at least as strong as the second one and in several cases it 

 is distinctly broader than, although usually not quite as long as, the middle teeth 

 (Text-fig. 126). The discal carina of pronotum in larger specimens often is as 

 strong as the premarginal carina, but in some smaller specimens it may be reduced 

 to a short fingernail-like sculpture, sometimes hardly conspicuous. Length of 

 female 5-9 mm. 



$ (undescribed until now). 4-5-8-0 mm. In colour and shape of head and thorax very 

 similar to$. Gaster (Text-fig. 124) petiolate, usually red at base, with two narrow pale yellow 

 bands (front one often reduced at sides) on broadest part of carapace and a broader transverse 

 subapical macula, sometimes divided in two spots. First tergite slightly less than half as broad 

 as carapace, 1-3—1-5 times as long as broad, dorsally beset with very coarse piliferous punctures 

 but basal third impunctate though uneven, separated by transverse furrow or depression, 

 basally on either side with stout longitudinal keel delimited on mesal side by deep furrow, deep 

 triangular basal fovea also well delimited, its sides high. Second tergite transverse, convex, 

 punctured, sublaterally with vague keel, hind margin distinct; third tergite not well delimited 

 dorsally but its hind margin on epipleurum swollen, strongly curved, conspicuous. Epipygium 

 above the strong transverse depression slightly receding down and forwards, therefore hardly 

 visible from above; apical corners of carapace acuminate but closely applied to epipygium, 

 inconspicuous. Sternites narrow, 4-6 elongate; seventh (last) subquadrate, its hind margin 

 rounded-subtruncate. 



With the abdomen considerably narrowed at base and in female the fourth 

 tergite with subangulate hind margin, L. africana shows some features reminding 

 one of the genus Micrapion Kriechbaumer, but I do not think that genus has any 

 closer links with this species-group. 



Biology. In Uganda reared from Serapista denticulata (Smith), a Megacluline 

 bee.
