66 Dr. Sharp on the Rhynchophorous 



shining, not rugulose. Elytra with series of large punctures, as 

 deep behind as in front ; the interstices coarsely punctured. 



The determination is by no means certain. R. dy- 

 bofskyi appears to have been described from a single 

 male, and was distinguished from R. cupreus by the 

 ventral segments not being densely punctate in the 

 male. In our English examples of R. cupreus I do not, 

 however, find any sexual difference in the ventral punc- 

 tuation, and I shall not be surprised if cupreus be found 

 to be more variable than has hitherto been supposed; 

 and it may then include perhaps these Siberian and 

 Japanese forms, but the specimens obtained are quite 

 insufficient to decide the question. 



Four specimens in bad preservation : one from Tokio, 

 one from Sapporo ; also one without locality. 



Rhynchites conicus. 



Rhynchites conicus, Illig., Mag., vi., p. 306. 



Subashiri ; Wada-toge, 1st August, 1881. Three 

 examples. This European species has also been found 

 in Siberia. 



Rhynchites apertus, n. s. 

 Minor, viridi-cyaneus, elytris cyaneis ; brevissime pubescens ; 

 rostro brevi, capite baud lato ; prothorace subcylindrico, crebre 

 punctato, sat nitido ; elytris seriatim fortiter punctatis, interstitiis 

 subconvexis, parce subtiliter punctatis. Long, cum rostro vix 

 3 mm. 



Eostrum short, in the male only about as long as the head, in 

 the female a little longer ; head moderately broad, finely and 

 sparingly punctate. Thorax rather longer than broad, greatly 

 narrower than the elytra, nearly cylindric, rather closely punctate, 

 the punctures neither coarse nor rugulose, the interstices shming. 

 Elytra with series of coarse punctures, with very little punctuation 

 on the narrow subconvex interstices. Legs short and stout, basal 

 joint of the hind tarsi quite short. 



This minute species is somewhat near R. conicus ; the 

 first row of punctures is quite regular at the base, and 

 there are no intercalated punctures. 



Six specimens ; on the main island, and on Yezo, 

 Kashiwagi, Nagasaki, and Chiuzenji.
