74 Z. BOUCEK 



I examined both original syntypes of L. pulchriceps and selected the lectotype. 

 I also examined the original couple of L. formosifacies and compared them with 

 the holotype of L. elegans Weld. They are all conspecific. 



The pale markings are mostly yellow, more rarely ivory white. Otherwise the black parts 

 (usually with metallic tint) are often red instead anteriorly on the pronotum and in a streak 

 in the depression of hind coxa.

Leucospis colombiana sp. n. 



(Text-figs 78-80) 



$. 9-1 1 mm. Black with weak mainly violaceous tinge which is more apparent on head, 

 pronotum and mesopleurum, subalar area more bluish, vertex at carina and sides of propodeum 

 green; pale lemon-yellow are: scapus except above, a short anterior and a complete posterior 

 band on pronotum, hind margin of mesoscutum between parapsidal vestiges (broadest medially), 

 scutellum except basal two-fifths, dorsellum, broad triangle on upper mesepisternum, meta- 

 pleurum along hind margin, mid and hind coxa on dorsal edge, dorsal edge of fore femur and 

 tibia, line on mid tibia anteriorly, dorsally on hind tibia (this also on apical spine) and hind 

 femur, latter also along ventral margin, then first tergite with two large triangular maculae 

 posteriorly, fifth tergite with band near hind margin bent ventrally forwards, sixth tergite and 

 epipygium with curved vertical lines. Wings moderately infumate but darker fuscous along 

 anterior margin, less so at apex. 



Head hardly broader than pronotum, dorsally nearly 2-4 times as broad as long; temples 

 extremely short but distinct owing to occipital carina which is dorsally, inside of eye margins, 

 very low. Vertex densely punctured-reticulate, except narrowly outside lateral ocelli and a 

 broader smooth depression on either side of median ocellus; POL about 1*43 OOL, ocellar 

 triangle about 2-6 : 1, without ridge between mid and lateral ocellus. Frontal protuberances 

 low; emargination of eyes weak; scrobal carina dorsally sharp. Head in facial view 1-31 times
