AUT. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 55 



posteriorly densely bipunctate, the larger punctures not nearly equal- 

 ing the largest punctures of the scutellum in size. Legs with major 

 calcariura of hind tibia having a distinct bend near the middle where 

 calcarium is slightly wider than at base ; hind basitarsus with a groove 

 and with a group of 3 or 4 lanceolate spines on the outside, one of 

 which is apical. Tegula with inner hind corner not produced in a 

 broad angle, only sparsely hairy, with no hairs extending far above 

 tegula when viewed from opposite side. Wings smoky; first cubital 

 mark vaguely defined. Propodeal areola with sides nearly parallel, 

 two to two and one-half times as long as wide; its carinae narrow, 

 bordered by well developed grooves; median carina complete. Lower 

 portion of side of propodeum mostly shagreened, with a patch of very 

 fine hairs posteriorly. Propodeal slope without well developed 

 punctures; median carina usually confined to lowest two-thirds. 

 First abdominal tergite with its preapical band varying from one 

 puncture wide at center to several at the sides, not in a depression, 

 most of the punctures separated. First sternite with lateral groove 

 complete to near anterior apex, with shallow punctures anteriorly. 

 Tergites with punctures not farther from apex medially than later- 

 ally; impunctate border three to four times the width of hindmost 

 ])rimary punctures. Pygidium densely reticulo-punctate on basal 

 three-fifths; impunctate apex with numerous wrinkles, broadly sha- 

 greened on wrinkled portion. Length, 9 to 14 mm. 



Male. — Vertex with dense secondary punctures invading the dor- 

 sum from behind on a front wider than ocellar triangle; primary 

 punctures back of ocellar triangle of first-degree density. Front 

 faintly shagreened, with primary punctures on lower portion sparser 

 and more limited in distribution medially than along ej^es ; preocellar 

 area with numerous interspaces nearly as broad as ocellus; second- 

 ary punctures forming a dense patch on lower two-fifths, extending 

 upward slightly more medially than near the eye. Antennocular 

 distance equal or slightly greater than width of antennal fossa. 

 Clypeal extension with its apical width from four-sevenths to two- 

 thirds the clypeoantennal distance ; apex shallowly emarginate ; mar- 

 gin narrowly but distinctly polished, impunctate, and slightly up- 

 curled. Pronotal punctures with clearly defined margins, some- 

 what denser medially than on humeri, mostly of third-degree density; 

 secondary punctures widely and sparsely distributed. Side of 

 pronotum finely striate, with a strong central groove which is usu- 

 ally uninterrupted. Mesepisternum with primary punctures small, 

 deep, and clearly outlined, everywhere of third-degree density; 

 secondary punctures much more numerous than primaries, densely 

 studding the interspaces. Scutellum with impunctate apex not as
