snbquadrate, the club with a minute terminal spine.

Cephalic axilla metallic green. 
3. GYROLASELLA CONSOBRINUS Girault.

metallic. Reared from galls, forest, December 12, 1912. Types on a slide. Line 6 of abdomen 
with a line-like caudal offshoot on eacli side of meson; 7 consisting of a round dot on each- 
side of meson and an area at each lateral margin.

The types are on a slide. They wore captured May 28, 1912 in forest (1,500 feet). 
5. GYROLASELLA LINEATA Girault.

view plus part of stalkl of an ordinary pin, extends to scntellum but the head^^ is separated 
‘“New species. Female; — Length, 1.8.5 mnn Honey yellow, the wing.s hyaline, the body marked with bright 
metallic green as follows: Pronotum, scutuin except lateral margins narrowly, meson of scutellum rectangularly, the 
green not extending quite to the lateral groove, a longer than wide spot at mesal base of postscutellum, mesa! 
half or more of each parapside, axilla? except lateral and caudal margins, propodemu except transversely just cephalad 
of the spiracle, immediate base of abdomen and seven thin cross-stripes, tlic first four close together (2 and 3 more 
prominent, crescentic, 3 embracing 4), o broader, joined narmwly to 4 along meson : 6 caret-shaped ; 7 near apex, 
narrowly interniplied at meson : a dot at edge between h and G. Eyes convergent, the. facual margin conve.x 
Ocellar area, a large, cuneate spot on vertex caudad of eye, pedicel above and a longitudinal stripe along upper side 
of scape ; mesoventer, hind coxa above at base and cephalic femur ventrad, also green. Propodenm noncarinate.
