Autoserica castanea, sp. n. 



Oblongo-ovalis, castaneo-rufa, opalescens, clypeo lato,nitido, fortiter 

 punctato, antice valde reflexo, subtilissime sinuato, medio loviter 

 longifcudinaliter cariuato, fronte opaco, parce punctato et ciliato ; 

 pronoto sat punctato, lateribua antice leviter arcuatis, post ice 

 fere rectis ; scutello fere rugose punctato ; elytris profunde 

 punctato-striatis, interstitiis irregulariter distincte jDunctatis. 



Long. 9-9'5 mm. ; lat. max. 5-5-6 mm. 



Hub. Japan : Kobe (/. E. A. Lewis, 18. 6. 1912); 

 N. China : Tientsin, Shanghai, Foochow. 



This is common in Japan, where it has been taken by 

 Mr. G. Lewis, Lord Dormer, and others, but tbe localities 

 have not been recorded. 



It is exactly like A. flammea, Brenske (Hong Kong), but 

 the clypeus is less rugose, the forehead more sparsely 

 punctured, and the elytra have more convex interstices and 

 less punctured striae. 



Aserica orientalis, Motsch. 



Two or three species occur to which Motschulsky's vague 

 description equally applies, and the identification is therefore 

 uncertain in the absence of the type. 



The names of three species of Apogonia have been recorded 

 since the list of 1895, two of them described by Mr. Lewis 

 himself, and this does not complete the Japanese species, of 

 which one more is added here, while others must follow when 

 more specimens are available. 



In describing Apogonia bicarinat a (Ann. & Mag. Nat. Hist. 

 (6) vol. xvii. 1896, p. 333), Mr. Lewis characterized the front 

 tibia as "not conspicuously dentate," but noting an excep- 

 tion in one "malformed" example from Oshima I. Al- 

 though I do not know that specimen, it appears from three 

 individuals from the Loochoo Is. (one of them taken by 

 Mr. J. E. A. Lewis at Okinawa) that the type is the really 

 malformed (or worn) example, and that the supposed 

 malformation is a characteristic of the species. There are 

 two well-marked terminal teeth and some fine serrations at 

 the base. The carina on the upper face is elevated near the 

 base, forming an obtuse angle there, and the outer edge of 

 the tibia is drawn inwards towards this angle, presenting the 

 appearance of a distortion. 



The other species mentioned above is here named : —
