aUT. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 31 



nearly everywhere except irregularly between ocelli and lower orbits, 

 on lower half more densely grouped medially than near the eyes. 

 Clypeus with its lateral margin strongly convex; extension with its 

 apex impunctate except for minute punctures, the impunctate apex 

 defined by coarse punctures which are not in a regular, transverse 

 low, the longitudinal extension of the impunctate apex equal to two- 

 fifths the distance from apex of clypeus to base of antennae. An- 

 tenna with its first joint slightly angulate apico-ventrally ; third joint 

 longer than its greatest width. Pronotum with its transverse carina 

 completely and strongly developed ; primary punctures of first-degree 

 density over whole anterior dorsum, with no transverse discal band; 

 secondary jDunctures almost lacking; median width of punctate area 

 exceeding that of impunctate. Side of pronotum with a series of 

 very irregular, short, interrupted grooves and punctures extending in 

 a tapering series across the center ; punctures distinct along the dor- 

 sal border, coalescing in a depressed patch just before the tegulae. 

 Scutum with its notauli and its anterior medial groove continuous. 

 Metanotum with a medio-apical callosity, punctures nearly as coarse 

 as those of the scutellum. Legs with major calcarium of hind tibia 

 tapering from base; hind basitarsus on the outside with a row of 

 three pricklelike spines terminating before apex. Tegula with inner 

 hind angle produced and upcurled, bearing dense yellow pile with 

 some longer, suberect hairs. Wings very smoky, with first cubital 

 mark not well defined. Propodeal areola hastate, twice as long as 

 wide; outside carinae bordered with interrupted grooves; median 

 carina usually irregularly broadened, with polished surface anteri- 

 orly, usually confined to upper three-fifths, with reticulate connec- 

 tions posteriorly; enclosed areas outside the reticulations smooth. 

 Lower portion of side of propodeui|| with its anterior portion highly 

 polished, posterior half with dense patch of conspicuous setigerous 

 punctures. Posterior aspect of propodeum coarsely but shallowly 

 punctate over all its surface; median carina strongly developed on 

 lower half or less. First abdominal tergite dorsally with dimpled 

 primary punctures, no preapical band, but a deep preapical groove, 

 overlapped except at sides. First sternite with a median groove 

 broken by transverse ridges; lateral grooves on posterior half or less; 

 shallow punctures widely distributed over disk. Tergites 2, 3, and 4 

 with pronounced marginal incised lines but without dense patches of 

 secondary punctures or any short, brown pile; no impunctate mar- 

 gins. Pygidium coarsely reticulo-punctate on basal three-fifths, usu- 

 ally without well-defined impunctate emargination of the punctate 

 base, but with a low median carina extending the full length of 

 the segment, apex anteriorly shagreened and strongly wrinkled. 

 Length, 11.5 to 14.5 mm.
