ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 21 



margins of the tergites. Pygidium without a median impunctate 

 emargination of the punctate upper portion. Tlie male is not known. 



Distribution. — Keikido, Chosen. 



In the collection of the Japanese Beetle Laboratory are to be found 

 the following: Two females, Suigen, Chosen, August 1 and 2, 1925 

 (Sato), Gardner No. 2, and 3 females, Suigen, Chosen, July, 1926

 have been deposited in the British Museum and in the collections 

 of the Illinois Natural History Survey and the Philadelphia Academy

2. TIPHIA OVIDORSALIS, new species 



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

 in limited areas between and just behind the ocelli and near the upper 

 orbits of the inner eye, elsewhere of third-degree, with irregular 

 impunctate spaces. Front faintly shagreened below, with impunc- 

 tate stripe and groove; primary punctures of lower front scarcely 

 more dense medially than toward either eye, of first-degree density 

 just above base of antennae, along the impunctate stripe to lowest 

 ocellus, and along orbits of inner eye, with a vague, trident-shaped 

 area where primary punctures are lacking or of second-degree 

 density, Clypeus with its lateral margin strongly convex ; extension 

 with impunctate apex limited above by coarse punctures not in a 

 regular transverse row. Antenna with its third joint distinctly 

 longer than its greatest width. Pronotum sometimes faintly sha- 

 greened, with the transverse carina complete but low across the 

 dorsum; primary punctures in a vaguely defined transverse discal 

 band, scarcely less dense on lateral disks than medially, largely of 

 second-degree density; secondary punctures sparsely scattered on 

 anterior half; punctate area medially of greater longitudinal exten- 

 sion than the impunctate. Side of pronotum with a groove in the 

 center about one-fourth the length of the sclerite, preceded by sev- 

 eral short gouges or round punctures. Mesepisternum with a well- 

 developed premarginal crease or groove along its posterior border. 

 Metathorax with a minutely punctate apical callosity, and on either 

 side with coarse primary punctures which are nearly as large as 

 those of the scutellum. Legs with the major calcarium of the hind 

 tibia usually tapering from the base; hind basitarsus with one or 

 two prickle-shaped spines on the outside, but none of the same type 

 at the apex. Tegula with a narrow, abruptly thickened posterior 

 margin. Wings very smoky. Propodeal areola keystone-shaped, 

 one and two-thirds to two times as long as wide ; lateral carina bor- 

 dered on outside by interrupted grooves; medial carina tapering
