AUT. 6. STUDIES ON LEUCOSPIDINAE C. J. WELD. 17 



furrows above on either side on median line, which diverge toward 

 triangular polished spot at base ; area between furrows arched, with 

 narrow polished median line; third and fourth tergites short, con- 

 stricted ; fifth scarcely one-fourth length of sixth ; sixth shorter than 

 first, swollen toward middle, its dorsal surface greenish iridescent; 

 apex of abdomen strongly compressed. Ovipositor flattened toward 

 apex, reaches a little beyond middle of propodeum. 



Described from one female collected at Chapada in March.

9. LEUCOSPIS ELEGANS, new species. 



In Eoman's key this species runs to egaia Walker, from which it 

 differs in shape of metanotum, femoral teeth and in color markings. 

 It also resembles opalescens, new species, but shows distinct differ- 

 ences in length of propodeum, shape of metanotum, wider hind femora 

 and in general coloration. 



Female. — Length 9.1 mm. An iridescent species with yellow mark- 

 ings, pronotum loithout transverse carina, hind coxae spurred and 

 ovipositor longer than abdomen. 



Body varicolored, ground color dark with blue-green and red 

 metallic tints and yellow markings as follows: transverse complete 

 band near hind margin of pronotum; shorter incomplete band of 

 similar width on hind margin of mesoscutum; narrow band near 

 hind margin of scutellum; median crescent-shaped spot on metano- 

 tum; triangular spot on mesopleura beneath tegula; faint oblique 

 line on metapleura; stripes on front legs along upper and lower 

 margins of femur, inner surface of tibia; apex above and half of 

 margin beneath of middle femur and under side of tibia; narrow 

 stripe along upper margin of hind coxa, which covers spur, and spot 

 near base beneath ; broad band on lower front margin of hind femur, 

 which extends from base nearly to apex and covers large basal tooth, 

 band along upper margin narrowing toward base and an elongated 

 spot near apex beneath; broad band on hind margin of second 

 tergite interrupted in median line ; a band of about same width on 

 seventh, which extends over a small portion of eighth segment in 

 median dorsal line. Scapes are rufous in color, as are also the 

 tegulae and front margin of pronotum, especially at sides and near 

 middle. Legs, except where mentioned, rufous to dark brown. 



Head brilliantly iridescent with garnet, gold, and green tints; 

 face finely rugosely punctate, short pubescent; line from median 

 ocellus to level of clypeus only slightly longer than interocular space; 

 malar distance about one-third length of eye; clypeus sinuate at 

 edge; eyes sinuate; vertex broad closely punctate, postocellar space 

 1.6 times ocellocular; occiput concentrically striate below, carinate
