centic, slightly shiny, extremely finely punctured, extremely finely and shortly pubescent, 

 apex convex, narrowly rounded. Sternites medially depressed, narrow, the third transverse, 

 fourth to sixth distinctly elongate, subequal in length; seventh (last) less elongate, apex 

 narrowly rounded.

This species is very close to, although clearly different from, L. santarema 

 Walker and L. klugii Westwood; but unlike them, L. pictipyga sp. n. has shorter 

 pubescence, particularly on the thorax. In that it resembles more L. brasiliensis 

 sp. n. and the two dark-winged species, L. leucotelus Walker and L. propinqua 

 Schletterer. 



Leucospis klugii Westwood 



(Text-fig. 49) 



Leucospis Klugii Westwood, 1839 : 249, pi. 3, fig. 1, $. LECTOTYPE q* (here designated), 

 Mexico (MNHU, Berlin) [examined]. 



The apparently single original specimen is designated as lectotype. I have seen 

 both males which Schletterer had for study (1890: 257-259). The female has not 

 previously been described. 



§. 8-8 mm. Black; with pale yellow: scapus, narrow band at posterior margin of pronotum, 

 narrow hind margin of scutellum, hind corner or margin of metapleurum, apex of hind coxa 

 ventrally, hind femur along ventral margin and generally distal two-fifths of gaster, including 

 nearly half of fifth tergite but excepting narrow black margins of tergites and epipygium (also 

 along ovipositor) ; dorsally at base of fifth tergite often a small yellow spot. Wings subhyaline, 

 slightly yellowish brown at anterior margins. Pubescence of body yellowish, rather long. 



Head dorsally 2-4 times as broad as long; occipital carina sharp, touching lateral ocelli 

 but disappearing outside of them ; scrobal carina weak, indistinct at ocellus ; frontal protuber- 

 ances low. Head in facial view 1-26 times as broad as high, face weakly convex, interantennal 

 lobe not carinate medially, genae converging at about 60 degrees; lower margin of clypeus 

 produced, bilobed, median tooth not distinctly developed. Relative measurements: head 

 height 52, frontovertex width 39, scrobes 20 (their margins not extending below toruli), lower 

 face width 36, height 27, eye 34-0 : 21-5, malar space 12-5, mouth width 25, scapus 17 ; flagellum 

 plus pedicellus about 1-14 times the breadth of head, moderately clavate, distal funicular seg- 

 ments slightly transverse. 



Pronotum with raised swollen premarginal carina; sides hardly converging, subconcave; 

 lateral panel low, very shallowly depressed. Dorsellum very transverse, slightly convex, 

 except for posterior smooth half, with dense piliferous punctures ; no trace of carina. Propodeum 

 medially nearly 1 -5 times as long as dorsellum, moderately densely hairy, hairs directed forwards ; 

 median carina and plicae narrow, weak. Hind coxa in depression punctured, less densely 

 so at dorsal edge and posteriorly with smooth area. 



Gaster about twice as long as broad (Text-fig. 49), very densely punctured and hairy, apex 

 in dorsal view subacuminate. First tergite narrower than gaster posteriorly as o-8 : i-o, 

 i-i times as broad as long; basal fovea strongly reduced, hind margin of tergite straight, sides 

 diverging; dorsally with smooth ovipositorial furrow. Hind margin of fourth tergite medially
