138 Z. BOUCEK 



missing, dorsal streak on hind femur sometimes shortened basally, ventral spot shorter, antennal 

 scape pale beneath ; gaster with yellow band behind broadest part and a vague median subapical 

 spot; epipygium reddish. On head POL about 2-5 times OOL. In facial view head 1-25 

 times as broad as high. Relative measurements: width of head 57, frontovertex 32, lower 

 face 26 (below antennae), its height 19-5; eye 35-0 : 24-5, malar space 6-5, mouth 24; clypeus 

 nearly 1-3 times as broad as high. Flagellum subclavate, combined with pedicellus nearly l«a 

 times as long as width of head. Propodeum raised medially and here about 1 -6 times as long 

 as dorsellum, median carina vague but plicae high. Gaster (Text-fig. 163) hardly shorter than 

 head plus thorax, distinctly petiolate, posteriorly as broad as mesoscutum, narrowest in one- 

 third of length. First tergite subpyriform, convex; except at base and at apex coarsely punc- 

 tured and hairy; in dorsal view about 1-7 times as long as broad, laterally at base with longi- 

 tudinal swelling separated by a shallow groove dorsally; hind margin subrectangularly excised 

 in middle; maximum breadth only 0-36, minimum breadth of tergite 0-31 the width of gaster. 

 Third (second exposed) tergite subcarinate at sides, carinae strongly diverging and gradually 

 fading off further back; hind margin of tergite between carinae emarginate, dorsum finely 

 reticulate but nearly without punctures. Carapace about 1 -45 times as long as broad, regularly 

 convex, densely coarsely punctured, pilosity rather short. Epipygium apically rounded, sides 

 of sixth tergite not toothed. Sternites very narrow, broadly deeply concave (grooved), last 

 but one about twice, the two preceding ones each about 2-5 times, last sternite only slightly, 

 longer than broad ; deep concavity of the last subtriangular, apex of last sternite rounded. 



Biology. Host unknown. 



Distribution. Madagascar, eastern South Africa. 



Holotype $, Madagascar: Fort Dauphin, ii. 1937 (A. Seyrig) (MNHN, Paris). 



Paratypes. Madagascar: Ivondro, i. 1939, 1 <$ {A. Seyrig) (BMNH). South 

 Africa: 'Kaffraria', about 1890, 1 $ (E. Holub) (NM, Prague). 



I cannot suppress some doubt about the origin of the female, being unable to find 

 any other specimen among the rich African material of the genus at my disposal, 

 although the label seems to be genuine and the specimen certainly comes from the 

 collections of E. Holub, a famous Czech explorer of Afiica, after whom the species 

 is named. Therefore I designate a male as the holotype. 



L. holubi is a very distinctive species, which seems to be remotely related to the 

 fuellebomiana-group.
