 AND SPECIES (No. 8). 



BY F. BATES. 



The following two species of Diaperis differ considerably from 

 the European species in the form of the presternum. In the latter 

 it is strongly and acutely produced and compressed before the coxfe, 

 and is prominent and sub-horizontal, or very gradually declivous, 

 behind the coxa) ; in the former it is abruptly convex or elevated 

 from the anterior margin, and is more (Lewisi) or less {sanguinei- 

 pennis) abruptly declivous — and but Kttle produced — behind. 



DiAPEEis Lewisi, sp. n. 



Form and punctuation as in _D. boleti ; the bands, &c., on the elytra of a bright 

 red ; the basal band is prolonged behind, at the margin of the elytron, and is of 

 nearly equal width tliroughout, or but slightly contracted just before the suture ; 

 the dorsal band is wider, slightly arched, and very strongly toothed at the margins ; 

 the apical mark is much larger than in D. boleti, and extends some distance up the 

 elytron, where it widens out, the upper edge being twice notched, the inner notch 

 the largest and deepest ; as in D. boleti, these bauds do not reach the suture, which 

 is black throughovit ; the joints of the antcnn£e are less compact than in D. boleti, 

 more wedge-shaped, appearing coarsely serrate within. 



Length, 3i lin. ; width of elytra, 2 lin. 



Hab. : Japan ; three examples. 



Besides the radical difference in the form of the presternum, this 

 species is also very distinct by the differently formed and coloured 

 bands on the elytra, which show no disposition to vary in the three 

 examples before me. The species has the usual blunt tubercle on the 

 disc of each elytron, which is one of the characteristics of the genus. 



Diaperis saxguiijeipennis, sp. n. 



In this species, the form is slightly more parallel, the punctuation a little 

 coarser ; the prothorax is made more unequal by numerous shallow fovea3 j the
