Hub Loochoo Is. : Okinawa (J. E. A. Lewis, 23rd May, 

 1913). 



This insect has a very close relationship to A. major, Wat., 

 which has the front angles of the prothorax similarly 

 hollowed out. It is a little smaller than A. major and [ess 

 shining, with the sides of the prothorax straighter and more 

 convergent in frout and the front angles acuter and more 

 deeply hollowed. The sculpture of the upper surface is 

 strong and close, the clypeus very coarsely punctured, the 

 forehead densely and confluently, the pronotum still more 

 closely and deeply, but with the sides less closely punctured 

 and rather shining. The lateral edges are strongly rounded 

 behind the middle, and from there to the very acute front 

 angles they are nearly straight, strongly convergent, and 

 reflexed. 



Lachnosterna inelegans, Lew. 



This is treated by Messrs. Lewis and Waterhouse as the 

 L.parallela of Motschulsky, whose name is preoccupied by 

 Blanchard. Motschulsky's insect, however, was from Shang- 

 hai, and it is not L. inelegans but a species with protuberant 

 pygidium very closely related to L. diomphalia which occurs 

 in that region and which has hitherto been confused with 

 it. The name parallela not being available, the hopeless 

 problem of its identity is happily not of importance ; but, 

 from the point of view of geographical distribution, it is 

 necessary to record that L. inelegans is known only from 

 s. Japan and Formosa. L. diomphalia, described from 

 Korea, is found also at Nagasaki and in N. China (Wei-hai- 

 Wei), and exceedingly closely related species are lound in 

 other parts of China. 



Rhizotrogus niponicus, Lewis, belongs rather to Brahmina, 



having the claws split and not toothed. They arc rather 

 short and the inner lobe is very bread.
