ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 23 



Exp. 318. Deposited in the British Museum: One female, August 

 4, 1925 (Sato), Gardner No. 10, and 1 male, Jap. Beetle Par. Exp. 

 318. Deposited in the collection of the Illinois Natural History 

 Survey: One female, Jap. Beetle Par. Exp. 318. Deposited in the 

 collection of the Philadelphia Academy of Natural Sciences: One 

 female, August, 1926 (Gardner), Gardner No. 10. 



Those specimens bearing label "Jap. Beetle Par. Exp. 318" 

 (Japanese Beetle Parasite Experiment 318) were reared from fe- 

 males collected in Chosen, the males thus obtained being from kno^Yn 

 females. 



The species ovidorsalis, koremia, and antige'nata are the only ones 

 as yet studied in which the very characteristic erect brown pile has 

 been found in the female. Ovidorsalis differs from korecma in hav- 

 ing the brown pile confined to the dorsal part of the tergite, and 

 from antigenata in having the premarginal groove of the first tergite 

 less strongly overlapped, with fine punctures visible behind the edge 

 of the fold. In specimens used in breeding work at Suigen, Chosen, 

 in August, 1926, the premarginal groove of the mesepisternum is 

 reduced to a hair-fine crease or is even lacking altogether. One fe- 

 male of this lot which has no fine, erect brown pile on the dorsum 

 is referred to this species because of information obtained from bio- 

 logical studies and because the conformation of the first tergite is 

 typical of the species. 



3. TIPHIA ANTIGENATA, new species 



Female. — Vertex with primary punctures of first degree density 

 everyw^iere except in limited areas on either side of postocellar 

 patch. Front polished ; groove vaguely defined ; primary punctures 

 densely and irregularly distributed, their outlines elongated toward 

 ocelli ; medially on anterior half the combined area of primary punc- 

 tures exceeds that of their interspaces, but laterally from this place 

 they become much sparser, everywhere of first degree density except 

 on vaguely trident-shaped area below ocellar triangle. Clypeus 

 with its lateral margin slightly convex: extension with its apex 

 impunctate except for minute punctures; impunctate area defined 

 by coarse punctures, not limited by regular transverse row, its longi- 

 tudinal extension equal to about one-fourth the distance from apex 

 to base of antennae. Antenna with its third joint distinctly longer 

 than broad. Pronotum with the transverse carina complete and 

 strongly developed; primary punctures well differentiated from 

 the secondaries, evenly distributed, mostly of first-degree density, 

 with no distinct transverse discal band ; secondary punctures include 

 a very few punctures in the anterio-medial area; longitudinal exten- 

 sion of the punctate area medially about equal to that of the im-
