50 Dr. Sharp on the Rhynchopliorous 



After examination of a considerable series of speci- 

 mens, I can find no characters to distinguish the above 

 forms except colour, and this no doubt is variable, as it 

 is in the well-known A. coryli, which runs through an 

 analogous series of colour variations ; intermediate 

 individuals are, however, rare, but still they do occur, 

 and I have several such before me. 



A. hicolor, Eedt., I am acquainted with only by the 

 description, and by Faust's note in Hor. Ent. Boss., 

 xxi., p. 28 ; this colour-variation has not occurred in 

 Japan as yet, but I mention it because it appears to be 

 the form intermediate between the typical A. erijtlirop- 

 terus and the Japanese var. minhnus, Eoel. ; while the 

 variety recorded by Redtenbacher, with thorax entirely 

 red, is no doubt the same as A. iimiimiis itself. 



The typical form of A. eriifhropterus is very rare in the 

 parts of Japan visited by Mr. Lewis ; he, however, 

 obtained two examples of it at Seba, July 30th, 1881, 

 agreeing entirely with Siberian examples, and with 

 them he obtained two examples with the elytra inter- 

 mediate between black and red in colour. 



A. erythrogaster differs strikingly in the colour of the 

 legs and ventral segments ; the colour of the latter 

 parts is, however, very variable in the var. nitens, so 

 that I attach no importance to it ; and the colour of the 

 legs is so variable in some other species of the genus 

 that I do not think it proper to rely on it alone as a 

 specific character. 



AjJoderus geminus, n. s. 



Niger, nitidus ; elytris rufis, regulaviter et fortiter seriatim 

 punctatis, interstitiis subconvexis, crebre punctulatis. Long. 

 4 — 6 mm. 



This IS possibly only a variety of sculpture of A. erythropterus, 

 but deserves even in that case a separate name ; the serial punc- 

 tures being as deeply impressed on the apical as on the basal 

 portion of the elj'tra, and the interstices more convex and closely 

 punctate. 



A small series was obtained from Kiga, Nikko, and 

 Miyanoshita, on Lespedeza.
