THE GENOTYPES OF SAWFLIES AND WOODWASPS. 107 



NEOPTILIA Ashmead. 

 Neoptilia Ashmead, Can. Ent., vol. 30, p. 213, 1898. 

 Type. — Neoptilia mexicana Ashmead. 



Belongs to the Schizocerides of Konow, and runs, in Konow's tables (Genera Insec- 

 torum, Fasc. 29, p. 13, 1906), in with Uemidianeura W. F. Kirby and Ptilia Lepeletier, ' 

 or to Rhagonyx Konow. Elongate, robust species; head not especially small or trans- 

 verse, not as wide as the thorax, much broader than high; clypeus and labrum emargi- 

 nate anteriorly; ocelli in a curved line, the lateral ones in front of the supraorbital line; 

 eyes slightly converging to the clypeus; malar space very narrow, antennal furrows 

 present; ocellocular line subequal with the postocellar line; antennse inserted in the 

 middle of the face, ciliate, furcate in the male, simple in the female and scarcely 

 thickening apically; tibiae without lateral spurs; post-basitarsis not as long as the 

 following joints; tarsal claws cleft, the inner tooth larger and shorter in the female; 

 thorax normal for the group. Venation of females as follows: Intercostal cell without 

 a cross- vein; radial cell with a strong appendiculation; four cubital cells, the second 

 receiving both recurrent veins, the second near the middle, the first near the base; basal 

 vein slightly basad of the origin of the cubitus, bent basally and not exactly parallel 

 with the first recurrent; transverse median slightly basad of the middle of the first 

 discoidal; anal cell very broadly contracted; in the hind wings the radial cell is long 

 and not closed at the apex; two closed discal cells, the upper one much longer; trans- 

 verse median at right angles with the anal vein; anal cell shorter than the rest of the 

 anal vein. The venation of the male differs from that of the female in the absence 

 of the second transverse cubitus. Basal plate with a narrow longitudinal suture. 



Rhagonyx Konow (Zeitschr. syst. Hyin. Dipt., vol. 3, p. 108, 1903) 

 has the claws cleft, and is perhaps related to Neoptilia Ashmead. 



NEOPTILIA MEXICANA Ashmead. 



Neoptilia mexicann Ashmead, Can. Ent., vol. 30, p. 213, 1898. 



Colored simliarly to Hijlotoma biramosa King, which has been placed 

 in different genera by different authors. There are some minor dif- 

 ferences, however, and the standing of hiramosa is so uncertain that 

 mexicana should be held distinct until King's type can be studied. 



Female. — Length, 11 mm. Labrum deeply arcuately emarginate; clypeus with a 

 deep V-shaped notch; labrum, clypeus, and supraclypeal area with rather large punc- 

 tures; front with small well-separated punctures; vertex impunctate; supraclypeal 

 area broadly convex, triangular; carina between the antennae high but not sharp; 

 postocellar area parted, with a median furrow, wider than the cei^halocaudad length; 

 postocellar furrow not sharply defined; postocellar line subequal with the ocellocular 

 line; thorax shining; third cubital cell more than twice as long on the radius as on 

 cubitus. Black; angles of the pronotum broadly pallid; abdomen, except the black 

 second and third dorsal segments, pallid at the base and reddish yellow at the apex; 

 legs, except the anterior tibiae at base beneath, black; wings beyond the basal nervure 

 distinctly brown, basad hyaline; venation black; head with pale hair. 



3Iale. — Length, 9.5 mm. The male differs from the female in the usual sexual 

 characters and the arcuately emarginate clypeus. Hypopygidium very large, apex 

 truncate. 



Type locality. — San Rafael, Jicoltepec, Mexico. Three females and 

 one male in the collection of Dr. Wiiliam H, Ashmead. 

 Type.— Cat. No. 13133, U. S. National Museum.
