ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 29 



first-degree density betAveen and on either side of the ocelli, those im- 

 mediately behind the triangle rather sparse and irregular, and not 

 more dense than on either side. Lateral margin of clypeus convex. 

 Third antennal joint longer than greatest width. Metathorax with 

 vestigial apical callosit3% its punctures coarse and at least half as 

 large as the largest on the scutellum. Propodeal areola hastate in 

 outline, two and one-fourth times as long as its greatest width. First 

 tergite with a deep preapical groove broadly overlapped on the 

 dorsum and with dimpled punctures. First sternite with a wide, 

 polished, impunctate median stripe flanked by dense, minute punctures 

 and sparse, round primary punctures; lateral groove obsolete. Ter- 

 gites two to four without large patches of dense secondary punctures 

 or of erect, short, brown pile ; with strong premarginal grooves over 

 the dorsum. 



Male. — Not known. 



Distribution. — Keikido, Chosen; Iwate, Japan. 



Deposited in the collection of the British Museum : One additional 

 specimen from Kowai, Japan, August, 1926. 



This species is referred to by Mr. Clausen under his number 1385. 



7. TIPHIA FOSSATA, new species 



Plate 1, fig. 1 



Female. — Vertex with primary punctures scarcely denser medially 

 than on either side, everywhere of second-degree or third-degree 

 density except small patches near upper portion of eyes and between 

 ocelli. Front polished; primary punctures densely and irregularly 

 distributed ; medially, on anterior half, the combined area of primary 

 punctures exceeding that of their interspaces, but from this place 

 becoming scattered and of second-degree and third-degree density. 

 Clypeus with its lateral margin slightly convex; apex impunctate 

 lor one-fourth the distance to base of antennae, except for extremely 

 minute punctures. Antenna with the third joint distinctly longer 

 than broad. Pronotum with its transverse carina strongly developed 

 except for a narrow gap in the middle ; primary punctures very well 

 differentiated from the secondary punctures, densely and evenly dis- 

 tributed over the whole punctate area, no transverse discal band; 

 secondary punctures sparse and confined to anterior median area; a 

 narrow but distinct median impunctate stripe ; the median longitudi- 

 nal extension of the punctate area distinctly greater than that of 

 the impunctate area. Side of pronotum with upper surface polished, 

 striate, with numerous well separated, round punctures along the 

 upper border. Mesepisternum with a strong premarginal groove on 

 its posterior slope. Metanotum densely double-punctate, punctures
