ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 75 



very wide, with primary punctures of irregular second-degree and 

 third-degree density and with interspaces broader than an ocellus; 

 secondary punctures very dense below, not well differentiated from 

 primaries on bipunctate area, ascending half way to lowest ocellus 

 medially and about one-third of the way along eyes. Antennocular 

 distance about equal to the width of antennal fossa. Clypeal exten- 

 sion with its apical width four-fifths the clypeoantennal distance; 

 disk flat and not protruding; apex shallowly emarginate, lacking an 

 impunctate margin, but with a thick edge. Pronotum with primary 

 punctures small, fairly well outlined, largely of third-degree density; 

 a few secondary punctures close to carina. Side of pronotum finely 

 striate, without a definite medial groove. Mesepisternum with small, 

 sparse, well-outlined primary punctures; secondary punctures dense 

 on upper half and bordering the prepectus and posterior margin, less 

 numerous than primaries only on the small callosity above the coxa; 

 no premarginal groove, though appearing shallowly impressed in 

 certain lights. Scutellum, except medially, with impunctate apex not 

 as Avide as largest apical primary punctures. Metanotum with dense 

 secondary punctures apically, elsewhere with sparse primaries nearly 

 equaling the largest of the scutellum in size. Tibiae and tarsi of 

 first two pairs of legs mostly reddish. Tegula polished, translucent, 

 red. Wings with radial cell slightly exceeding cubital cell. Propo- 

 deum with areola rectangular in outline, nearly twice as long as wide, 

 lateral carinae without bordering groove, the median carina sinuous, 

 the inclosed area somewhat rugose. Side with lower region not punc- 

 tate or hairy but finely shagreened; posterior aspect densely hairy 

 and punctate, with a median carina on lower half. 



First tergite Avith preapical band narroAv, deeply impressed, of 

 nearly uniform width, its punctures fading out on surface of de- 

 pression. First sternite with lateral groove on posterior third ; disk 

 with vague punctures and a sharp median keel anteriorly. Tergites 

 3 to 5 moderately shagreened, with punctures extending to apex. 

 Fifth sternite with its lateral denticle appearing more like a crescent 

 than a tooth. Length, 6.5 mm.
