Although I hope that I have recognized correctly the damaged type of L. 

 varicollis, I must admit that a mistake is possible. With the discovery of the 

 following species which I name L. osmiae the matter may be rather complicated, 

 for the until now unknown males of this species may be very similar to those I 

 classify with L. varicollis above. The problem can be solved only when both 

 sexes are known and more information is available.

(Text-figs 142, 143) 



$. 5 -0-5 -5 mm. Black, with poor pale yellow and red markings; whitish yellow are: 

 narrow (sometimes subinterrupted) band anteriorly on pronotum, posteriorly on scutellum, 

 on fourth tergite (sometimes reduced), at hind margin of fifth tergite and a short streak ventrally 

 at base of hind femur; red are, more or less: narrow hind margin of scutellum, tegula, sides of 

 propodeum with parts of metapleura, first tergite (paler at base), ovipositorial furrow on fifth 

 tergite, mainly fore and mid legs except coxae, apex of hind coxa, both ends of hind femur, 

 hind tibia and tarsus. Wings distinctly and rather uniformly infuscate, about as in L. africana. 



Head as broad as pronotum, dorsally twice as broad as long, with temples rounded and 

 strongly receding but face fairly convex. Vertex not very convex; occipital carina sharp
