NO. 1930. DESCRIPTIONS OF NEW 8AWFLIES—R0HWER. 207 



Genus NEOPTILIA Ashmead. 



NEOPTILIA MALVACEARUM (Cockerel!). 

 Nematoneura malvacearum Cockerell, Insect Life, vol. 7, No. 3, 1894, p. 252. 



In characters which may be useful to separate genera this species 

 differs from the type of the genus in the rather shorter flagelhim and 

 third basitarsi's. The nonclaviform antennge exclude it from Nema- 

 toneura. The antennae are about as long as the mesonotum; the 

 flagellum is of nearl}'' uniform width throughout. 



Judging from the description Khagonyx is a synonym of Neoptilia. 



TANYPHATNIDSA, new genus. 



Belongs to Sterictiphorinse. In Konow's latest tables to this 

 group this genus would seem to run to Nematoneura Andre; or, 

 assuming that the flagellum is not claviform, to TanypTiatna Konow. 

 From both of these genera it may be separated by the second and 

 third cubital cells, each receiving a recurrent vein. 



Head much narrower than the thorax; clypeus slightly emarginate; 

 antennae inserted near the middle of the face; malar space large, 

 greater than the width of the mandibles at the base; posterior 

 orbits broad; ocelh in a low triangle, the lateral ones on the supra- 

 orbital line; pedicellum very short, much wider than long; flagellum 

 rather long and thickening apically; thorax normal; propodeum 

 chitinous; tibiae without spines; basitarsis III much shorter than the 

 following joints; sheath broad basally, narrowed apically; tarsal 

 claws simple; basal vein joining the costa at the origin of the cubitus; 

 radial cell appendiculate ; four cubital cells, the third large, the second 

 and third each receiving a recmTent vein; transverse median near 

 the middle of the cell; hind radial cell appendiculate; two discal 

 cells; lanceolate cell subequal in length with the petiole; anal vein 

 normal. 



Tyj^e.—TanypJiatnidea microcephala Rohwer. 



TANYPHATNIDEA MICROCEPHALA, new species. 



Female. — Length 8 mm. Labrum broadly rounxled apically, 

 rather long; clypeus depressed apically, convex basally, the apical 

 margin arcuately emarginate, sharply defined above by the suture; 

 supraclypeal foveas deep, punctiform; supraclypeal area flat; anten- 

 nal foveae present laterally, elongate; middle fovea elongate and 

 extending to the anterior ocellus; postocellar area obsolete; post- 

 ocellar line much shorter than the ocellocular line; antennae about 

 as long as the thorax; stigma long, strongly tapering; first recurrent 

 vein in basal tliird of cell, second recurrent a little basad of the basal 

 third; third transverse cubitus straight, about half as long again as the
