AET. 17 WASPS OF IHE GENUS TIPHIA ALLEN AND JAYNES 27 



Tergites 3 and 4 with dense secondary punctures which merge with 

 the sparse primary punctures apically ; impunctate margins at center 

 at least three times the width of adjacent primary punctures, lateralh' 

 with deep, incised marginal lines which become faint rows of very 

 minute vestigial punctures over the dorsum on these two segments. 

 Pygidium on basal half coarsely rugose, without impunctate emar- 

 gination of the punctate base; apical impunctate section vaguely 

 carinate, with pronounced wrinkles and shagreening; stylet and 

 sting palps not prominently protruding. Length 8 to 10 mm. 



Male. — Not known. 



Distrihution. — Assam, India. 



Type.— Cat. No. 41776, U.S.N.M. Female, Shillong, India, May, 

 1927 (Clausen). Clausen No. 2056. 



Single females of the same lot as the type have been deposited in 

 the collections of the British Museum, the Illinois Natural History 

 Survey, and the Philadelphia Academy of Natural Sciences. The 

 remaining eight specimens, also labeled like the type, are retained in 

 the collection of the Japanese Beetle Laboratory. 



The female of this species differs from the female of the closely 

 related antigenata in having a dorso-medial row of minute punctures 

 on the vertex, in having the width of the apex of the propodeal 

 areola less than half the greatest width of the areola, and in having 

 a shorter, narrower medial carina in the propodeal enclosure. Un- 

 fortunately, this species is represented by a small series of more or 

 lesii fungus-covered specimens, in which the best specimen by far is 

 atypical in having a wider, longer medial carina in the propodeal 

 areola, a carina on the lower half of the posterior aspect of the propo- 

 deum, and a crenulate median groove on the first sternite. 



5. TIPHIA TEGITIPLAGA, new species 



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

 between and on either side of ocelli, of third-degree density back of 

 ocelli, and still sparser on either side. Front polished, with inter- 

 rupted groove ; primary punctures becoming shallower above, rather 

 regularly distributed, except that they are somewhat denser on the 

 loAver half where they are slightly more closely grouped medially, 

 everywhere of first-degree density except in a vaguely defined area 

 borderinf^* the ocellar triangle below. Clypeus with its margin 

 slightly convex; apex not entirely impunctate, the punctures extend- 

 ing irregularly almost to apical margin. Antenna with third joint 

 distinctly longer than its greatest width. Pronotum with its trans- 

 verse carina completely and strongly developed; primary punctures 

 mostly of first-degree density, evenly distributed, with no transverse 

 discal band; secondary punctures almost lacking; longitudinal ex- 

 tension of the punctate area medially slightly less than the impunc-
