REVISION OF LEUCOSPIDAE 81 



femur, tibia (Text-fig. 87) and tarsus as in L. birkmani, but femur externally slightly more 

 densely punctured and with yellow, not whitish markings. Fore wing: apical processus of 

 stigmal vein broader and longer than uncus. 



Gaster in shape much as in L. birkmani: first tergite with two broad diverging dorsal furrows 

 which are punctured on bottom; tergite about i-i times as long as broad, about o-8 as broad 

 as posterior half of gaster, nearly twice as long as fifth tergite medially; ovipositor reaching 

 scutellum. Puncturation in general denser than in birkmani, on fourth tergite dense also in 

 basal half and pilosity forming a thick silvery fascia on fourth tergite, a golden fascia posteriorly 

 on fifth tergite and thickly covering apex of gaster behind spiracles (of sixth tergite) ; on fourth 

 and fifth tergites hairs directed obliquely downward, on epipygium mainly backwards but with a 

 belt parallel to ovipositor with hairs directed downward. Epipygium on ventral side with a 

 dark purplish line parallel to ovipositor.

Leucospis desantisi sp. n. 



(Text-figs 89, 90) 



9. 7-6-IO-5 mm. Black with conspicuous metallic tinge varying from bright or brassy- 

 green (upper mesepimerum, broad hind margins of first, fourth and fifth tergites and apex of 

 gaster) to dark violaceous; yellowish are scapus beneath, band at hind margin of pronotum 

 (sometimes interrupted medially), lateral and posterior margins of mesoscutum, usually hind 

 margin of metapleurum, fore and mid knees above, upper edge of fore tibia, hind femur along 

 dorsal edge and more broadly triangularly at base, hind tibia except at ends; red are antennae 

 except apically, pronotum broadly anteriorly submedially (sometimes reduced, sometimes 

 extended to broad band connected submedially with posterior yellow band; the latter in 

 holotype), sometimes also sides of propodeum and hypopygium of gaster reddish. Fore wing 

 infumate, dark brownish along anterior margin with a pronounced spot apically at end of 

 shady line from stigmal vein. 



Head slightly narrower than pronotum posteriorly, in dorsal view about 2-3 times as broad 

 as long. Occipital carina moderate, not reaching far laterad beyond ocelli; temples immargined 

 and rather narrow. POL : OOL as 12 : 11; ocellar triangle nearly 2-5 : 1, space between 

 lateral and median ocellus moderately elevated; vertex laterad of ocelli densely punctured, 

 some punctures longitudinally confluent. Scrobal carina uninterrupted, but not high where 

 touching median ocellus; frontal protuberances moderate. Face finely rugulose-punctured, a 

 few coarser punctures interspersed at sides not conspicuous; slightly shiny, pubescence 

 extremely short. Interantennal lobe medially sharply edged to carinate, supraclypeal area only 

 weakly convex. In facial view head about 1-24 as broad as high. Relative measurements: 

 width of head 75, frontovertex 46, width of scrobes 25, of lower face 44, its height 27, eye 

 40 : 25, its inner orbit hardly emarginate; malar space 12, width of mouth 33, scapus 20. 

 Clypeus about 1*4 times as broad as high, its produced lower margin broadly bilobed, medially 

 excised and impressed. Scapus about 3 times as long as broad. Flagellum plus pedicellus 

 hardly longer than width of head, weakly clavate, apically about 1 -4 times as broad as pedicellus ; 

 first flagellar segment hardly longer than pedicellus, slightly longer than broad; second about 

 1-2 times, eighth about o-8 times as long as broad, middle ones subquadrate to slightly 

 transverse; clava I-6-I-8 times as long as broad. 



Pilosity of thorax extremely short, puncturation moderately dense, including scutellum, very 

 dense on pronotum submedially; interspaces narrow, dull, with distinct microrecticulation.
