Rhynchophorous Coleoptera of Japan. 8? 



PiAzoMiAS, Schonterr. 

 1. Piazomias velatus, Chev. ? 



Piazomias velatus, Roelofs, Ann. Soc. ent. Belgique, 

 xvi,, 1873, p. 164. 



I enter this in the Japan list, solely on the authority of 

 M. Roelofs, who says of it, " Tres commun an Japon." 

 There are, however, no examples of it in the Lewis 

 collection. Indeed, I have not yet seen any Chinese 

 example of the genus that agrees with the Japanese 

 exponents, and Chevrolat described the species from 

 China. 



2. Piazomias lewisii, Roel. 



Piazomias lewisi, Roelofs, Ann. Soc. ent. Belgique, 

 xxii., 1879, C.R., p. liii. 



This species was not described in M. Roelofs' first 

 paper on Japanese Rhynchophora, and 1 think it possible 

 that it was this insect he alluded to in his first paper, 

 under the name of P. velatus : in which case, the latter 

 name should be withdrawn from the Japanese cata- 

 logue. 



According to Mr. Lewis's collection, this is by no 

 means a prominent insect in the Japanese Coleopterous 

 fauna ; he found a few specimens in the island Kiushiu, 

 in April, and one at Kobe, on the south coast of the 

 Main island. 



SCEPTICUS. 



Scepticus, Roelofs, op. cit., xvi., 1873, p. 158. 

 1. Scepticus insnlaris, Roelofs, I. c. 

 This species has been found sparingly in various 

 localities throughout the three islands, from Nagasaki to 

 as far north as Sapporo. 



GROUP III. 



Amystax. 



Amystax, Roelofs, Ann. Soc. ent. Belgique, xvi., 

 1873, p. 159. 



1. A. fasciatus, Roelofs, I. c, p. 160, pi. ii., fig. 2.
