finely and weakly reticulated, the frons and vertex with similar but 

 stronger sculpture; antennee separated at base by a distance about 

 equal to that between the base of antenna and the eye inargin; scape 

 slender, flattened outwardly; pedicel three times as long as thick, about 

 equal in length to the first funicle joint and the ring-joints combined; 

 four distinct, transverse, ring-joints; funicle three-jointed, the first 

 joint the longest and about twice as long as thick; second joint distinctly, 

 though not a great deal longer than broad and a little longer than the 

 third; third joint subquadrate; club solid, and very slightly longer than 

 the two preceding funicle joints conibined; pronotum and mesoscutum 

 strongly shagreened, parapsidal grooves deep, praescutum without 

 trace of a median groove; scutellum more weakly sculptured than the 

 mesoscutum, lineolate-reticulate with the paired dorsal grooves distinct, 

 but without a median groove; propodeum rather long, distinctly, though 

 not deeply, reticulate-punctate, slightly shining, with a distinct median 

 carina; mesepisternum and prepectus sculptured like the mesoscutum; 

 mesepimeron mostly polished, its dorso-posterior margin reticulated; 

 hind coxae strongly reticulate-punctate; abdomen as long as the head 

 and thorax, slightly narrower than the thorax, pointed at apex, the first 

 and basal half of second tergites polished, the apical half of second and 

 the following tergites distinctly reticulate-punctate; second tergite a 

 little shorter than the first; third and fourth large, subequal, and each 

 about as long as the first. Black; flagellum brownish testaceous; 

 scape, anterior tibise, basal half and narrow apical portion of median 

 and hind tibiae testaceous; all tarsi pale yellowish, the apical joint black; 

 wings hyaline, venation testaceous. 



Male. Length 1.25 mm. Antennal scape with a slight keel-like 

 expansion on apical half beneath; three transverse ring-joints; funicle 

 four- jointed, the first joint small and subquadrate or very slightly 

 broader than long, second joint one and one-half times as long as broad, 

 third very slightly longer than broad, the fourth quadrate; club solid, 

 nearly as long as the three preceding funicle joints and distinctly thicker 

 than the funicle; abdomen subpetiolate, about as long as the thorax, the 

 first tergite a little longer than the second, smooth; second and third 

 tergites sculptured, the third about twice as long as the second, tergites 

 beyond the third very short. Scape black, flagelliim testaceous. 

 Otherwise like the female. 



Type locality, Tempe, Arizona. Type, Cat. No. 22301,

Two females and six males reared by V. L. Wildermuth 

 from Cecidomyid stem-galls on Pluchea borealis and recorded 

 under Tempe No. 2742. 



Galeopsomopsis transcarinatus, new species. 



Very similar to G. midtisulcatus Girault, but may be distinguished 

 by the fact that the first funicle joint is the longest of the funicle joints, 

 the true metanotum is smaller, not quite so strongly sculptured, with the
