twice broader), the postmarj^inal \cin is sul)cqual to ihc stignial 

 (distinclK- longer in begini) and the funicle joints are not subequal. 

 The inancHhles are 4- and o-dentate in l)oth species, and in both 

 the caudal tibial spurs are single. Differs from pitlchripes in that 

 the said annulus is narrower, not extending to the middle (distad 

 of it in pulchripcs); also the scape is wholly black (white at basal 

 third in the other species). In pitlchripes, both mandibles arc 

 5-denate and the caudal tibial spurs siti^le. From ivebsteri in 

 the colour of the legs; the median carina of thepropodeumis distinct, 

 not as in pitlchripes but very delicate as in websteri and begini; and 

 in websteri the postmarginal vein is longer than the stignial. In 

 websteri the mandibles and scape arc as in pitlchripes, also the caudal 

 tibial spur. 



Propodeal spiracles minute and round, the lateral carinic 

 absent. Funicle 1 longer than wide, 2 sulKjuadrate. Club with 

 a distinct terminal nipple in all four species and this terminates 

 a small conical joint, so that the club is 4-jointed. 



Described from one female reared at Kingston, Rhode Island, 

 Januarx (>, 1916, from Phytomyza chrysanthemi (A. E. Stone). 



Type. — Catalogue No. 20193, V. S. N. M.. the specimen in 

 fragments on a slide. 



Pseudiglyphomyia coptodiscae new species. 



Female. — Length, 1.60 mm. Char^icterized by bearing on 

 the fore wing an obcuneate brown stain from the stigmal \ein 

 and of moderate size (extending nearly across the blade). 



Lemon yellow, the following parts dark metallic green; Occiput 

 at upper half, ocellar area, proximal half of pedicel, scape except 

 at extreme base, apex of the neck of prothorax, somewhat over the 

 cephalic third of the scutum (except at lateral margin), the green 

 area with a scalloped caudal margin, the scutellum except lateral 

 margins except at base and the cephalic and caudal margins be- 

 tween the grooves (the cephalic more broadly yellow and irregular), 

 "postscutellum except lateral and apical margins, propodeum except 

 laterad of the spiracle, dorsal thorax laterad of the postscutellum 

 and apical scutellum except at lateral margin, base of abdomen 

 narrowly (except at meson more or less), caudal coxa? dorso- 

 proximad broadly, a rather broad stripe around abdomen just
