 ZAGRAMMOSOMA NIGROLINEATA, new species. 



Female. — Length about 1.25 mm. Lemon yellow; tip of scape 

 and base of pedicel brownish; pedicel distinctly longer than first 

 joint of funicle; second joint of funicle about as long as first; club 

 distinctly longer than the two joints of the funicle combined; rear 

 of head with a narrow dusky transverse line above level of lower eye 

 margins, this line widened at eye margins; thoracic notum with a 

 median dark line extending backwards to propodeum; a spot on 

 each side on anterior margin of pronotum and one on posterior lateral 

 angles, anterior margin of mesoscutum, inner edge of parapsidal 

 areas, a spot on axillae, lateral margins of scutellum, a spot just back 

 and centrad of anterior wings, propodeum except extreme sides, spot 

 at base of abdomen, and some suffusion on disk of abdomen, all brown;

Type-locality. — Compton, California. 



Two specimens mounted in balsam on separate slides and with the 

 additional data "Chittenden (U. S. Dept. Agric. Bur. Entom.) num- 

 ber 2180, bred from material Aleyrodes sp., etc., Graf, collector." 



Type.— Cat. No. 15362, U.S.N.M. 



It is very probable that this species came from some lepidopterus 

 leaf minor in the material in which the Aleyrodes were found. 



This species differs from the others in the genus, in addition to the 

 different pattern of markings, in having the pedicel longer than the 

 first joint of the funicle. 



SYMPIESIS METACOMET, new species. 



Female. — Length about 2.5 mm. Green; face almost smooth; 

 pedicel subquadrate; joint one of funicle distinctly longer than two, 

 the following joints successively shorter, the last hardly longer than 

 broad ; pro-, meso-, and Inetanotum strongly, coarsely, reticulately 

 rugose, the rugae on the scutellum somewhat finer, those on the 

 axillae much finer; propodeum with a strong median longitudinal 

 carina, with weak lateral carinae and a transverse carina this last 

 doubled for most of its length; basal pair of areolas rugulose; pre- 

 pectus reticulately rugose; wings hyaline; legs testaceous, the hind 

 coxae with a large green spot; abdomen about as long as head and 

 thorax together.
