This new Cassida is not very nearly allied to any yet recorded 

 from Japan or Siberia. It may easily be recognized by the el)'tra 

 with one long smooth costa near the suture, which, commencing at 

 the base, nearly reaches the apex ; two other raised interstices, 

 forming costules, start, one from inside, the other from the summit 

 of the humeral callus ; but these are shortened and confused with 

 the rugose sculpture sooner than the sutural one. The thorax is 

 longer proportionally than that of C. equestris, to which, in having 

 its hind angles rounded, it may be compared ; but these angles are 

 more suddenly cut off, as it were truncated, and the whole surface is 

 very much more coarsely punctured. In one of the two examples, 

 in which the thorax is quite as wide as the elytra, there are two pale 

 spots, which Mr. Lewis observed in life to be of a fine green-yellow ; 

 this, I think, from its form and from the sixth segment of the 

 abdomen being distinct, to be the male. The suture is a little 

 raised and there is a deep sutural stria, between which and the first 

 costa there is an obsolete interstice and stria. The two basal black 

 marks are small spots, the external one elongate ; the two discoidal 

 ones are elongate dashes in line, but not united ; the submarginal 

 one is as long as these would be if united, and curved towards the 

 apex. Legs very distinctly punctured. 

 Two specimens ; found in Central Japan.
