ART. 17 WASPS OF THE GENUS TIPHIA ALLEN AND JAYNES 15 



11. Tergites 3 to 5 (sometimes only 3) with erect, brown pile much shortei* 



than the usual hairs 15. 



Tergites 3 to 5 with only the usual long, irregular, yellow hairs 12. 



iL'. Posterior slope of the mesepisternum with a premarginal groove parallel 

 to the posterior edge ; or if groove lacking, first sternite with its median 



fossa not creuulate 13. 



Posterior slope of the mesepisternum without a premarginal groove, though 

 sometimes with a vague impression which resembles a groove in certain 

 lights ; first sternite usually with a shallow, crenulate median fossa ; 

 pygidium usually with a strong, median, carinate wrinkle. 



(8) (China) communis, new .species. 

 i:'>. Punctures at center of tergite 3 much sparser than those caudad or ce- 



phuled of that region 14. 



Punctures at center of tergite 3 scarcely less dense than those caudad or 

 cephalad of that region ; secondary punctures of tergites 3 and 4 well 

 differentiated from the primary punctures ; first sternite with a deep 

 median fossa (7) (Chosen) fossata, new species. 



14. Median carina of areola nearly obsolete, replaced by irregular punctures. 



anterior portion expanded laterally ; first sternite with a polished, im- 



punctate, longitudinal stripe (6) (Chosen) autumnalis Rohwer. 



Median carina ending just before apex of the areola, not much expanded 

 anteriorly ; first sternite with a longitudinal median row of closely spaced 

 punctures, but without polished, impunctate stripe. 



(5) (Japan) tegitiplaga, new species. 



15. First tergite with a row of very fine punctures just behind its preapical fold ; 



pygidium not medially carinate, scarcely wrinkled on apical half. 



(2) (Chosen) ovidorsalis, new species. 



First tergite without a well defined row of punctures along posterior edge 



of premarginal fold . 16. 



16. Tergites with their brown, pilose areas very dense, and visible from any 



position, the brown pile abundant on sides as well as on the dorsum of 



the tergite (1) (Chosen) koreana Rohwer. 



Tergites with their brown, pilose areas beset with very short or sparse pile, 

 often visible only in profile against a light background, and becoming 

 sparser at the sides . 17. 



17. Apical callosity of metanotum densely and minutely punctate; vertex devoid 



of a dorso-medial row of minute punctures. 



(3) (China) antigenata, new species. 

 Apical callosity of metanotum without definite, minute punctui'es ; vertex 



with an irregular row of minute punctures. 



(4) (India) assamensis, new species. 



18. Pygidium deeply punctate or rugose-punctate on not more than the basal 



three-fifths 20. 



P.vgidium deeply rugose (not wrinkled) to the apex 19. 



19. Punctures of the pronotum evenly distributed ; sixth sternite with a median, 



longitudinal, impunctate line at least as long as the tapering part of the 



sclerite (27) (Japan, Chosen, China) bicarinata, Cameron. 



Punctures of the pronotum nuich denser on the posterior margin than else- 

 where on the punctate portion ; median, longitudinal, impunctate line on 

 the sixth sternite shorter than the tapering portion of the sclerite. 



(28) (Chosen) brevilineata, new species. 



20. Femora of last two pairs of legs black, at least on the outer, exposed parts ; 



tibiae rarely red 22. 



Femora of the last two pairs of legs wholly bright red 21.
