Subfamily Ophioninae. 



Tribe CAMPOPLEGINI. 

 Genus ANGITIA Holmgren. 



ANGITIA GALLEKIAE, new species. 



This species is extremely variable both in size and structure, the 

 extremes being so different that were they compared without the 

 intermediate variations one could not but consider them to be 

 diiferent species. Moreover the extremes run very close to the typi- 

 cal forms of Campoplex Gravenhorst and Sesioplex Viereck. Fortu- 

 nately the type series consists of a number of specimens, all from the 

 same source at the same time and displaying a gradual variation 

 from one extreme to the other. 



The formal descrip^on is based entirely on the holotype, while 

 the points of variation are taken up in a separate paragraph. The 

 holotype is selected from near the middle of the series of females. 



Female. — ^Length, 8 mm.; antennae, 4.5 mm.; ovipositor, 1.75 mm. 

 Temples strongly, convexly receding, occiput broadly concave, eyes 

 sinuately emarginate within; face very slightly narrower than frons; 

 malar space slightly more than half the basal width of mandible; 

 cheeks in front view straight; diameter of lateral ocellus distinctly 

 more than half as long as postoccllar line, which is about twice the 

 ocell-ocular line; antennae tapering at apex; head and mesoscutum 

 opaque without distinct punctures; pronotum laterally striate; 

 mesopleurum, mesosternum, and metapleurum minutely, opaquely 

 punctate; sternauli broadly impressed anteriorly; scutellum minutely 

 punctate, subpolished at base; propodeum laterally subpolishcd 

 coriaceous, medially transversely, irregularly regulose, the carinae 

 distinct and complete except that separating the areola and petiolar 

 areas, the basal area broad at apex; legs rather stout, -tibiae more 

 or less compressed, inner calcarium of hind tibia slightly longer than 

 half the basitarsus; areolet large, shortly petiolate, recurrent received 

 at middle; nervulus perpendicular, curved, petiole slightly broader 

 than thick, with a rather deep fovea on each side, the area between 

 this and the base flat, the dorso-lateral carina obsolete; post-petiole 

 slightly though distinctly thicker, longer than broad, the sides weakly 

 curved dorsally with a mechan and two lateral impressions just 

 behind the spiracles; second tergite three-fifths as wide at base as 

 long, a half longer than third, its sides weakly divergent, the spiracles 

 at about the middle, gastrocoeli distinct, nearly circular, removed 

 from base of segment by about their diameter; ovipositor sheath 

 about one and one-half times as long as first tergite. 



Black; mandibles, palpi, and tegulae white; scape and pedicel 

 reddish beneath, antennae otherwise black, hind and middle coxae
