ART. 17 WASPS OF THE GEXUS TIPHIA ALLEN AND JAYNES 43 



Since these varieties occur in Chosen, Avhich is much nearer the 

 habitat of the type of i^fomandibulata than is the locality of the 

 Chinese specimens seen by Mr. Gahan, it is possible that the species 

 we have named notopolita may be taxonomically nearer the type than^ 

 the one selected. 



Female. — Vertex with primary jDunctures of first-degree density 

 in very limited patches between ocelli and near upper part of eyes^ 

 elsewhere largely of second-degree density with irregular impunc- 

 tate spaces. Front shagreened on lower half, with a well-developed 

 median groove which extends half way to ocellus, and with an im- 

 punctate stripe ; primary punctures more densely grouped on anterior 

 half, where they are evenly distributed between the eyes, mostly of 

 second-degree density, with vaguely defined, trident-shaped impunc- 

 tate area below ocelli. Clypeus with its lateral margin distinctly 

 convex; apex impunctate except for numerous, barely visible punc- 

 tures, the impunctate apex poorly defined above by coarse punctures 

 which are irregular in size and arrangement. Pronotum with its 

 transverse carina complete; primary punctures of uniform size and 

 evenly distributed over the anterior portion of the dorsal aspect; no 

 transverse discal band; medial longitudinal extension of punctate 

 area slightly greater than that of impunctate area. Side of prono- 

 tum with definite groove across center, along the bottom of which 

 are numerous small rugulae, especially from center to alar angle; 

 no group of well-developed primary punctures on anterior half. 

 Metanotum finely, uniformly, and sparsely punctate, punctures much 

 smaller than those of the scutellum ; dense, minute punctures lacking. 

 Legs with major calcarium of hind tibia tapering uniformly; hind 

 basitarsus on outside with a group of four straight, stout, lanceolate 

 spines, one of which is apical. Tegula black, polished, with very 

 shallow marginal impression laterally and another impression on 

 posterior margin, both terminating in inward-directed hooks at the 

 lateral, posterior corner; outer impression sometimes lacking. Wings 

 densely smoky; second intercubitus sinuous, joining radius in a 

 rounded angle, usually without spur; first cubital mark barely per- 

 ceptible. Propodeal areola with its sides converging, scarcely two 

 times as long as wide; medial carina complete and of the same 

 size throughout, somewhat flattened and polished on top and bor- 

 dered by numerous short transverse ridges. Lower portion of sides 

 of propodeum rugulose over all the surface, but more conspicuously 

 so toward upper rugose portion. Posterior aspect of propodeum 

 conspicuously bipunctate, particularly on the lateral extension; me- 

 dian carina present as a strong, rounded, tapering rib on the lower 

 three-fourths, bordered by irregular transverse rugosities. First 

 tergite with a rather large median patch of dense, minute punctures ;
