ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 79 



ocellus; lower front with primary punctures gradually diminishing 

 in size, but without a well-defined bipunctate area. Antennocular 

 distance less than width of antennal fossa, Clypeal extension pro- 

 truding, with a convex disk ; clypeoantennal distance nearly twice the 

 apical width of the clypeal extension. Mesepisternum with primary 

 punctures large and clearly outlined ; the secondary punctures sparser 

 than the primaries except on the posterior slope. Apex of scutellum 

 impunctate or minutely punctate, distinctly wider than the lower 

 primaries. Primary punctures of metanotum as large as those of 

 the scutellum. Median carina of the posterior aspect of propodeum 

 usually complete to the upper transverse carina. First tergite with 

 a wide preapical band which is not in a depression, and which 

 consists of large, well separated punctures. First sternite with a 

 polished impunctate disk, a crenulate apical fossa, and numerous 

 deep punctures anteriorly, but lacking a lateral groove or a definite 

 antero-medial keel. Tergites 3 to 5 with impunctate apices as wide 

 at the center as six times the diameter of largest adjacent primary 

 punctures. Hypopygium with its impunctate median stripe widen- 

 ing caudally, and bordered by a tuft of dense, erect, white hairs. 

 Genitalia, in ventral aspect, with the outer clasper abruptly con- 

 stricted near the middle, the outer edge nearly straight, the inner 

 angle broadly crenulate; second genital segment with the apical 

 hook broadly spatulate, the inner hind margin sloping abruptly, 

 without marked convexity or angles ; distal portion of aedeagus with 

 the apical lobes very slender, much narrower than the broad lateral 

 processes; proximal portion of aedeagus tapering gradually from 

 near base toward constriction.
