2 o8 Z. BOUCEK 



broadened, dull, dorsally with arcuate broad carina. Hind coxa ventrally below lateral edge 

 shiny, sparsely punctured, extremely shortly hairy (Text-fig. 241), at base with impunctate 

 smooth area. Hind leg otherwise (Text-fig. 242) as in L. aruina, but tarsus more slender, 

 though still shorter than tibia. Stigmal vein of fore wing apically angulate, without distinct 

 processus; uncus long. 



Gaster generally as in L. aruina, i.e. posteriorly sides rather regularly converging. Yellow 

 band on broadest part crossing ovipositor at its apex.

The Gribodo Collection in Genoa includes one female and one male from the 

 type-material of L. gambeyi Maindron (as mentioned by Masi, 1935); I designate 

 the female as lectotype. A specimen under gambeyi in the Paris Museum, coming 

 from the Perez Collection seems also to have belonged to the original material and 

 is regarded as paralectotype. They are the same as L. antiqua. 



For some characters of L. antiqua see also Brues (1942). As mentioned above 

 with the aruina-group, this is a very distinctive species, differing from the above 

 group mainly by the raised discal carina on the pronotum. The key and the 

 text-figure provide further characters. The interantennal lobe is convex, rounded, 

 not acuminate dorsally as in all the other species of the genus. The sculptured 

 part of the sternites in the male is narrow but less strongly so than in L. aruina 

 Walker. 



Possibly L. antiqua and the preceding aruina-gvoup are the most primitive 

 species of the genus Leucospis. 



Biology. Host unknown. The species mimics the wasp Pachymenes quodi 

 (Vachal), Vespidae (Brues, 1942 : 154).
