96 Z. BOUCEK 



whilst in L. cayennensis Westwood and in L. mexicana it is weak, concealed under 

 the first tergite, without sculpture. 



Leucospis addenda sp. n. 



(Text-figs 1 18-120) 



(J. 8 mm. Black, with dark bluish, greenish or purplish tinge, but bright red-golden on 

 broad apex of gaster from middle of fifth tergite and a broad band posteriorly on fourth tergite; 

 pale yellow are: scapus beneath, narrow cross-band posteriorly on pronotum (arched along 

 hind margin), hind margin of mesoscutum between short parapsidal vestiges, a line on dorsal 

 edge of fore tibia, mid knee, a spot posteriorly on lateral edge of hind coxa, hind femur and tibia 

 dorsally, femur also ventrally but spot not reaching apex. Mandibles basally rufous. Wings 

 brownish yellow, marginal and postmarginal vein darker brown. 



Head as broad as pronotum anteriorly, dorsally crescentic, fully 2-3 times as broad as long; 

 temples not very short, slightly longer than breadth of median ocellus. Occipital carina not 

 high but reaching behind inner margins of eyes, then becoming blunt; vertex densely reticulate- 

 punctured, with some rugae converging towards temples; POL subequal to OOL; ocelli not 

 large, their triangle about 2-5 : 1, lateral ocelli touching occipital carina, median ocellus not 

 separated from scrobes which is not carinate above. Frontal protuberances rather high and 

 in anterior view bordered by a tooth-like elevation of scrobal margin, the latter as far from eye 

 as breadth of scrobes above. Head in facial view 1-18 times as broad as high (Text-fig. 119); 

 face rather swollen but depressed between toruli and eyes, lower face flat, interantennal area 

 convex and bluntly ridged medially. Pubescence extremely short, narrow interstices of rugulose 

 puncturation smooth. Relative measurements: height of head 60, width 71, frontovertex 44, 

 scrobes 21-5, lower face 40, its height 30, eye 39-0 : 24-5 (inner orbit hardly emarginate), malar 

 space 12, mouth 37, scapus 21. A small broadly triangular area below eye and reaching middle 

 of malar space without punctures but with extremely fine granulose reticulation. Lower 

 clypeal margin moderately produced, lateral lobes semicircular, median tooth short and broad. 

 Antennal flagellum slightly clavate, together with pedicellus nearly 1-2 times as long as breadth 

 of head; distal funicular segments transverse, basal ones elongate. 



Thorax very densely punctured, on mesoscutal disc punctures coarser, interstices raised and 

 slightly shiny, elsewhere dull. Pronotum without premarginal carina, hind margin emarginate, 

 sides slightly concave; lateral panel shallowly depressed, hind margin above semicircularly 

 emarginate. Scutellum fully 1-3 times as broad as long, slightly convex, with impressed cross- 

 row of punctures at hind margin which is narrowly impunctate. Dorsellum bare, irregularly 

 alveolate (bottom of alveolae smooth), subtriangular, sides with laminate carina which is slightly 

 lowered in middle; sides of metanotum with crenulate furrow. Propodeum medially about 

 1 -7 times as long as dorsellum; median carina in middle high and swollen, rugose on top; median 

 area with coarse rugose puncturation, basally with some longitudinal irregular rugae, hairs not 

 long and not dense, radiating forwards and sideways from apex of median carina; irregular plicae 

 conspicuous. Interspaces of punctures on upper mesepimerum subhorizontally striate. Fore 

 femur and tibia not distinctly carinate dorsally. Hind coxa : depression in posterior half with 

 longitudinal smooth area surrounded by sparse punctures, otherwise densely hairy but hairs 

 even dorsally unusually short, longest being the hairs at lateral edge; dorsal edge behind 

 broadened base narrow but blunt, not carinate. Hind femur (Text-fig. 118) externally densely 

 and rather finely punctured, with interspersed much coarser punctures. Hind tibia externally 

 densely punctured, apex truncate; basitarsus dorsally hardly as long as breadth of tibia; claws 

 weakly curved. Fore wing: apex of stigmal vein broad, rounded, much shorter than the slender 

 uncus. 



Gaster (Text-fig. 120) nearly 1-9 times as long as broad, broadest in three-fifths, moderately 

 narrowed forwards. First tergite about 0-7 times as long as broad and about 0-7 the breadth 

 of posterior part of gaster; basal fovea very small; dorsum convex, coarsely punctured, laterally
