AKT. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 39 



12. TIPHIA NOTOPOLITA, new species 



Feinale. — Vertex with primary punctures back of ocellar triangle 

 of third-degree density, though noticeably denser than on the lateral 

 vertex. Front shagreened on lower third, with a median groove; 

 primary punctures in preocellar area of second-degree density just 

 anterior to ocellar triangle, and of third-degree density on either 

 side, with several interspaces as wide as an ocellus. Clypeus with 

 its lateral margin slightly convex; impunctate apex of extension 

 poorly defined anteriorly but distinguishable one-fourth the distance 

 to base of antennae. Pronotum with its transverse carina complete ; 

 primary punctures uniform in size and evenly distributed over the 

 anterior dorsum without a trace of a transverse discal band; medial 

 longitudinal extension of punctate area equal to that of impunctate 

 area. Side of pronotum with a definite groove across the center 

 broken by unsculptured interspaces; anterior half usually with sev- 

 eral widely scattered, deep, round punctures. Metanotum impunc- 

 tate over much or all of its anterior surface, without a dense medial 

 patch of minute punctures. Metasternum shaped like an arrowhead, 

 with the outer wings well pointed and directed backward. Legs 

 with the major calcarium of hind tibia tapering from its base ; hind 

 basitarsus on the outside with a group of 3 or 4 stout spines, one of 

 which is apical. Tegula red, with a posterior marginal groove, and 

 with only a vague impression on the lateral margin, which does not 

 terminate posteriorly in an abrupt, inwardly directed hook. Wings 

 moderately smoky; second intercubital vein straight and joining 

 the radius at an abrupt angle. Propodeal areola two and one-fourth 

 times as long as wide ; sides slightly convergent, all the carinae bor- 

 dered with deep, crenulate grooves; median carina complete. Lower 

 portion of sides of propodeum polished, striate, with a limited area 

 of very minute hairs. Posterior aspect of propodeum quite com- 

 pletely bipunctate; its median carina present as a faintly elevated, 

 flat-topped ridge on the lower three-fourths or more. First tergite 

 with its preapical band well defined, not in an impression, and con- 

 sisting of well-separated punctures irregular in size and spacing, 

 narrowing to a single row at the middle. First sternite coarsely 

 coriaceous anteriorly, with lateral grooves on the posterior half. 

 Intermediate tergites with the apical punctures more elongate than 

 usual, and interspersed with minute, vestigial punctures which are 

 present over the dorsum on tergites 3 to 5. Pygidium densely and 

 evenly punctate on basal half, with an impunctate emargination ; 

 apex strikingly free from wrinkles and not shagreened. Length, 

 6 to 10 mm. 



Male. — Vertex with punctures scarcely denser just back of ocelli 

 than on either side, everywhere of third-degree density. Front with
