ART. 6. STUDIES OJSr LEUCOSPIDINAE — C. J. WELD. 35 



grove of ovipositor deep, smooth, with raised margin and faint 

 longitudinal line in bottom; third and fourth tergites short; fifth 

 less than half sixth; sixth about 0.8 of second, coarsely punctate. 

 Ovipositor reaches nearly to base of abdomen. 



Described from two females received from C. F. Baker.

Genus EPEXOCLAENOIDES Girault. 



Epexoclaenoides Girault, :Mem. (Queensland Musoimi, vol. 14, (1915) pp. 

 357-358. 



Genotype. — Epexoclaenoides biclnctus Girault. 



Epexoclaenoides recently established by Girault is based on a 

 single Australian species. It differs from the genus Leucospis in 

 shape of abdomen and character of teeth on hind femur as shown in 

 key above. 



EPEXOCLAENOIDES PYRIFORMIS, new species. 



This species agrees with Epexoclaenoides hicinctus Girault in hav- 

 ing very minute comb-like teeth on under side of the hind femur, 

 short ovipositor, simple metanotum, and hind coxa without a spur 

 on upper margin, but differs from it in size, color, pattern, and 

 probably in structure, although from description given, it is not pos- 

 sible to point our specific differences. 



Fe77iale. — Length 8.1 mm. A small black and yellow species with 

 abdomen narrow in front.^ nearly globular behind., a short ovipositor 

 and minute femoral teeth. 



Body black; tegulae, middle and hind coxa, hind femur beneath, 

 second tergite and ovipositor mostly rufous; following parts pale 

 yellow : scape, transverse bands near front and in hind margins of 

 pronotum, the former slightly wider in median line and dilated at 

 margins, the latter obsolete laterally ; short bands on sides of mesos- 

 cutum above tegulae; crescent-shaped markings on hind margin of 

 scutellum sometimes interrupted in median line; central part of 

 metapleura ; apex of front femur distinctly above, slightly beneath ; 

 small spot near apex of middle femur; front and middle tibiae 

 within; conspicuous spot at base of hind coxa on upper margin and 

 spot below near apex; apical two-thirds of upper margin of hind 

 femur widest at apex and a triangular spot on lower margin near 

 l)ase ; hind tibia above ; tarsi ; two transverse bands on abdomen, one 

 covering constricted portion just behind second tergite, narrow in 

 median line much wider laterally, the other near apex, its hind 

 margin touching groove of ovipositor. 



Head transverse, as wide as pronotum, face finely rugosely punc- 

 tate, silvery pubescent ; line from median ocellus to level of clypeus
