21. Tibiae usually blackish; preapical band of the first tergite well differen- 



tiated ; abdominal tergites 2 to 4 without shallow vestigial punctures in a 

 row just caudad of the large, preapical, setigerous primary punctures. 



(37) (Chiua) pigmentata, new species. 

 Tibiae red ; preapical band of the first tergite not differentiated ; tegites 

 with shallow punctures as described above. 



(3G) (Japan) biseculata, new species. 



22. Tegula at most only slightly longer than broad 23. 



TegTila nearly twice as long as broad, light red ; a small species. 



(39) (China) longitegulata, new species. 



23. Side of pronotum without well-differentiated groove across the center, or, 



if present, shallow and interrupted at frequent intervals 33. 



Side of pronotum with a well-differentiated groove across the center un- 

 interrupted for a distance at least one-half the length of the sclerite 24. 



24. Tegula black and opaque, except along the outer edge, or, if red, not trans- 



parent and thin 25. 



Tegula wholly red, very thin, and semitransparent ; pygidium with a dis- 

 tinct, apical, impunctate emargination in the basal, rugose half. 



(32) (Japan, Chosen) agilis Smith. 



25. Punctures of the punctate part of the pronotum much larger and denser in 



a line just anterior to the impunctate area than on the lateral disks of 



pronotum 30. 



Punctures of the punctate part of the pronotum at most only slightly larger 

 or denser in a line just anterior to the impunctate area than on the lateral 

 disks of pronotum 26. 



26. Pygidium wrinkled and strongly shagreened on impunctate portion ; carina 



of the posterior asi>ect of propodeum only rarely flattened, with the bor- 

 dering grooves, if present, vague and inteiTupted 29. 



Pygidium very smooth and free from wrinkles or shagreening on impunctate 

 portion ; carina of the posterior aspect of propodeum usually bordered on 

 each side by a narrow groove, its crest strongly flattened 27. 



27. Dorsal aspect of propodeum without a diagonally longitudinal carina laterad 



of the lateral areolar carina ; s'des of pronotum above the groove with- 

 out numerous, widely separated punctures 28. 



Dorsal aspect of propodeum with a diagcmally longitudinal carina laterad of 

 the lateral carina ; sides of pronotum above the groove with numerous, 

 widely separated punctures ; groove of hind basitarsus vestigial, less than 

 one-fifth the length of the joint. 



(26) (Philippines. China) compressa Smith. 



28. First sternite broadly coriaceous on the constricted base; stigma extending 



in a broadly rounded curve beyond the point of fusion with the radius; 

 groove of hind basitarsus deep, and at least one-half the length of the 



joint (24) (Borneo, China) malayana Cameron. 



First sternite not sculptured on the constricted base ; stigma abruptly trun- 

 cate at the point of fusion with the radius ; groove of hind basitarsus 

 shallow, vestigial, though nearly half the length of the joint. 



(25) (India) brevistigma, new species. 



29. Frontal punctures mostly of first-degree density ; areola at most scarcely 



more than twice as long as wide; metasternum with only one point to 

 each lateral apex, proximal to the hind coxa. 



(34) (India) matura, new species. 

 Frontal punctures of third-degree density at least on upper half; areola 

 nearly three times as long as wide ; metasternum with two distinct points 

 to each lateral apex proximal to hind coxa. 



(22) (China) inconspicua, new species.
