Rhynchophorous Coleoi'>tera of Jafan. Ill 



and acuminate. The females of several species have the 

 last ventral plate peculiarly formed. 



I. Clilorophanns grandis. 



C. graudift, Roelofs, Ann. Soc. Ent. Belgique, xvi., 

 1873, p. 162. 



Vak. higuhrig, n. var. Major, long. 15 mm., obscure fuscus, 

 elytrorum vitta lateral! fere nulla. 



Var. metallescens, n. var. Supra laate metallicus, prothorace 

 distincte ruguloso ; subtus pallidus. 



A small series of this species was procured near Oyama, 

 in May, 1880. Although the two varieties to which I have 

 given names, seem at first sight very different from the 

 type form, I feel sure that lugubris will prove to be con- 

 nected with the usual state of C. grandis. I have seen 

 only two examples of this form ; they were also found at 

 Oyama; a specimen found at Yokohama is apparently 

 intermediate. Of the variety metallescens only a single 

 individual was found, the locality being also Oyama; as 

 the sculpture of the thorax is an important character, it 

 may possibly prove to represent a distinct species, very 

 closely allied to C. grandis. 



2. CJiIorophanns planus, n. sp. 



Dilute viridis, pallide pulverulens, parum convexus, prothorace 

 elytris que vitta laterale parum discreta flavescente ; prothorace 

 brevi, lateribus obliquis hand curvatis ; elytrorum acuminibus minus 

 flongatis ; corpore subtus albido-viridescente. Long. 10 mm. 



Pallid green, without metallic lustre. Antennae quite short, 

 their club reddish, the other joints black but with much white 

 clothing. Rostrum short, a little narrowed towards the tip. 

 Thorax not in the least rugose, base almost straight. 



This species is readily distinguished from C. grandis 

 by the characters mentioned above as well as by being 

 only half the size, and by having the yellow stripe of the 

 elytra extending over two interstices instead of one. The 

 male has the chia-piece of the presternum not per- 

 ceptibly developed. The female has the tibial inucros 

 much longer than they are in the male.
