ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 87 



of third-degree density; secondary punctures fairly well differen- 

 tiated, and everywhere much more numerous than the primaries. 

 Scutellum with impunctate apex not as wide as the posterior pri- 

 mary punctures. Metanotum unusually convex, with primary punc- 

 tures of first-degree density nearly as large as those of the scutellum. 

 Tegula with a very fine, marginal, impressed line. Wings with the 

 radial cell not equaling the second cubital cell. Propodeum with its 

 areola strongly convergent, and from one and one-half to two times 

 as long as wide, longitudinal carinae highest at apex of areola, not 

 bordered by grooves, median carina usually nearly complete, broader 

 than the laterals, inclosed area granular-reticulate; lower portion 

 of sides densely shagreened and not perceptibly hairy; posterior 

 aspect granulate, its median carina usually lacking. First tergite 

 with its preapical band wide, poorly defined, in a broad, scarcely 

 perceptible depression, with the punctures distinctly separated. First 

 sternite with deeply crenulate apical fossa, lateral grooves on pos- 

 terior third, and distinctly bipunctate, with dense secondary 

 punctures covering the disk. Tergites 3 to 5 with vaguely outlined 

 punctures; impunctate margins at center as much as five times width 

 of the largest adjacent primary punctures. Denticle on fifth sternite 

 small, with its raised edge more nearly parallel to margin than to 

 longitudinal plane. Length, 6.5 to 8 mm. 



Distribution. — Shizuoka, Japan. 



Type and allotype.— C^i. No. 41803, U.S.N.M. Type, female,

 tional Museum: Four males and 3 female.s, June 13, 1920 (Clausen), 

 Clausen No. 1381, Rohwer No. 2; 1 male and 2 females, June 18, 1920 

 (Clausen), Clausen No. 1381, Rohwer No. 2; 8 females, October 4, 

 1924 (Ouchi), Clausen No. 1851, Rohwer No. 2; 16 males and 5 

 females, insectary reared; 6 females, September, 1926 (Gardner), 

 Clausen No. 1851; 198 females, October 1, 1926, 2 males and 18 

 females, Exp. 303, 1927. Retained in the collection of the Japanese 

 Beetle Laboratory: Four females, October 1, 1926, and 4 males, in- 

 sectary reared. Deposited in the collections of the British Museum, 

 the Illinois Natural History Survey, and the Philadelphia Academy 

 of Natural Sciences : Four females to each, October 1, 1926, and 1 male 

 to each, insectary reared. 



The sexes iiave been associated through breeding. Specimens 

 labeled " insectary reared " and " Exp. 303 " emerged at the Japanese 

 Beetle Laboratory from cocoons shipped from field stations in the 

 Orient. The cocoons were obtained from progeny of field-collected 

 females which are represented in our collection by the series collected
