OP WASHINGTON, VOLUME XIV, 1912. 5 



the antennae: vertex divided by a deep median furrow extending from 

 the ocelli to the occipital foramen. Mesothorax smooth, shining im- 

 punctate; the parapsidal furrows absent, the mesoscutum with a short 

 median longitudinal furrow or incision near its posterior margin; meso- 

 pleurae with a distinct furrow; propodium rugose with a short median 

 carina anteriorly becoming lost in the roughness of the sculpture pos- 

 teriorly. Wings hyaline; the stigma very narrow, only slightly thick- 

 er than the postmarginal vein, which is thickened throughout its whole 

 length; the first cubital cross-vein is entirely absent, the second re- 

 moved nearly one- third the length of the radius from the origin of the 

 latter; the cubital nervure abruptly cut off just beyond the cross-vein; 

 marginal cell reaching to the apex of the wing; costal, radial and 

 postmarginal veins and the stigma brownish, remainder of the neura- 

 tion pale. Palpi and legs brownish-testaceous, darkest above. Ab- 

 domen not longer than the head and thorax, smooth, shining, black; 

 ovipositor exserted half the length of the abdomen, brownish-testa- 

 ceous. 



Habitat: Manhattan, Kansas. 



Type: No. 14357, U. S. National Museum. 



Two slides bearing a large number of specimens were re- 

 ceived from T. J. Headlee for identification. These speci- 

 mens were taken from cages in which the Hessian fly was 

 breeding and are possibly parasitic on that insect. 



The species may be distinguished from S. nhtiicola 

 Ashm. by the incision on the mesoscutum and by the more 

 rugose propodium. Types removed from slide and mounted 

 on points; paratypes in the collection Kansas Agricultural 

 College, slide-mounted. 



CHALCIDOIDEA. 



TORYMID.E. 

 MONODONTOMERIN^E. 



Ditropinotus flavicoxus, new species. 



Female. Length 2.5 mm. Head and dorsum of the thorax golden 

 green, strongly punctate, the punctures of the head somewhat finer 

 than those of the thorax. Antennae dark brown, nearly black; the 

 scape and club orange yellow. Face below antennae with sericeous 

 white pile. Pleura?, underside of thorax (except mesosternum, which 

 is usually green), legs including all coxae, and abdomen honey-yellow; 

 the anterior coxae and middle tibiae are usually somewhat paler than 

 the rest of the legs, and the apical tarsal joints are dark. Abdomen 

 very finely, transversely lineolate, the ovipositor about half the length 

 of the abdomen and black.
