402 Mr. G. J. Arrow on the Lamellicorn 



punctured above. A slightly shining coppery-green variety 

 (var. borealis, m.) occurs in Hakodate, which is still nearer 

 to A, cuprea, so that the interval between A. mongolica and 

 A. cuprea is completely bridged and their separation as 

 Anomala and Euchlora respectively becomes impossible. 

 The difference in the front claws of the male referred to by 

 Mr. Lewis does not exist here. 



Belonging to the same group and closely related to the 

 last are A. albopilosa, Hope, and gracilis, Schauf. The 

 latter is considered by its author to be a variety of A. albo- 

 pilosa, but by Mr. Lewis to be a distinct species. In my 

 opinion the difference between species and varieties becomes 

 in these insects one of individual taste. Hitherto undistin- 

 guished from A. albopilosa, but really belonging to another 

 group, in spite of the close external resemblance, are the 

 two species which follow : — 



Anomala xanthopleura, sp. n. 



Supra viridis, pronoti et elytrorum margiuibus flavis, pygidio 

 metallico, antice viridi, postice flavescenti, corpore subtus roseo- 

 flavo, tibiis tarsisque cupreis, corpore supra subnitido, dense 

 punctato, clypeo truncato, rugoso ; elytris lineis longitudinal ibus 

 punctatis subsuturalibus et medianis (harum eircum 5) distincte 

 impressis, marginibus externis rerlexis, postice dilatatis et sub- 

 angulatim abbreviatis, subtus castaneis, sat late metnbranaccis ; 

 pygidio dense rugoso, fere opaco, vix piloso ; corporis subi us 

 lateribus punctatis, modice griseo-pilosis ; tibia antica bidcntata, 

 pedum anticorum et intermediorum ungue majori tisso : 



<$ , tibiaa antica? apice subacute, ungue majori antico fere ad apicem 

 minute angulatirn dilatato : 



9 , tibise anticae apice longe lobato. 



Long. 19-22 mm. ; lat. max. 11-12 mm.

This has the colour, size, and general appearance of 

 A. albopilosa, Hope, but in the peculiar dilated elytra and 

 sedeagus of the male it is quite different, and is evidently 

 closely related to A. expansa and truticata, Bates. It is 

 smaller than either, strongly and densely punctured above, 

 and rather more shining than A. truncata, but less so than 

 A. expansa, and markedly distinct also by the pale-coloured 

 lower surface and femora. The sedeagus of the male has the 

 paramera produced upon the centre line into a pair of short 

 overlapping lobes.
