19. Clypeoantennal distance scarcely greater than the width of clypeal exten- 



sion at its apex 20. 



Clypeoantennal distance twice as great as the width of the clypeal extension 

 at its apex (20) (Chosen, China) phyllophagae, new species. 



20. Pronotum not shagreened 21. 



Pronotum conspicuously shagreened (33) (India) piiUivora, new species. 



21. Apical half of first sternite without dense, minute punctures 22. 



Apical half of first sternite with dense, minute punctures. 



(36) (Japan) biseculata, new species^. 



22. Front with its .secondary punctures not extending medially above lower 



half; antennocular distance equal to or greater than width of antennal 



fossa 23. 



Front with moderate number of secondary punctures extending medially 

 nearly to lowest ocellus ; antennocular distance distinctly less than width 

 of antennal fossa (34) (India) matura, new species. 



23. Denticle on sixth sternite of usual size, its elevated edge more than half as- 



long as the median v^idth of the punctate. portion of the sternite; tegula 



bright red, thin and semitransparent 24. 



Denticle on sixth sternite very small, its elevated edge not half as long as 

 the median width of the punctate portion of the sternite ; tegula more oi* 

 less castaneous, thick, and opaqe ; secondary punctures of mesepisternum 

 everywhere well differentiated from the much larger primaries, and much 

 more numerous (22) (China) inconspicua, new species. 



24. Preapical band of the first tergite laterally with its dorsal punctures sep- 



arated from each other by interspaces wider than width of punctures, and 

 somewhat distinct from the rather shallowly impressed anterior por- 

 tion of the band (32) (Japan, Chosen) agilis Smith. 



Preapical band of first tergite laterally with its dorsal punctures separated 

 from each other by interspaces narrower than width of punctures, and 

 extensively coalesced with the deep, narrow, medial, impressed portion of 

 the band (31) (Chosen) asericae, new species.

The following supplementary notes may be helpful in fixing this 

 recently described species among those discussed in this paper. Fe- 

 male with primary punctures on vertex more sparse medially than 

 on either side. Clypeus with its lateral margin strongly convex 

 Third joint of antenna distinctlj^ longer than broad. Metanotum 

 with a minutely punctate apical callosity, elsewhere with coarse 

 punctures nearly as large as those of the scutellum. Mesepisternum 

 with a well-developed marginal groove on its posterior slope. First 

 tergite with its dorsal punctures dimpled; with a deep preapical 

 groove overlapped at the middle. First sternite with a crenulate 

 median groove; lateral groove on posterior half. Tergites 3 to 5 

 with conspicuous bands of dense, short, reddish pile, well differen- 

 tiated from the long, sparse, white hairs, and extending to the lateral
