The aiEnities of this curious genus, which is founded on a 

 email insect captured by Mr. Gr. Lewis in the Japanese Archi- 

 pelago, are extremely difficult ; for, whilst it possesses some of the 

 characters of the Coccinellidce and others of the Endomychidce, its 

 freedom, from a securiform last joint to its maxillary palpi would (even 

 alone) seem to remove it from the former, whikt the fact of its feet 

 being composed (as it appears to me) of only three articulations (for 

 I can detect no trace of a minute third one in the central region of 

 the second), debars it equally from them both. On the whole, taking 

 into account the reduced number of its antennal joints (which, at the 

 utmost, cannot be regarded as more than ten), its hemispherical out- 

 line, and the significant shape of its peculiarly coloured prothorax, 

 which is nearly entire in front, almost concealing from view the small 

 and sub-perpendicular, or dependent, head, and has the posterior angles 

 rather acutely produced, as well as the proportions of its uuder- 

 segments audits largely-developed scutellum and wings, I am inclined 

 to believe that it will be more natural to treat it as a gigantic and 

 aberrant member of the Corylophidcd ; though at the same time I am
