and an apical spot reddish 3'ellow. Basal band has four postei'ior 

 denticulations at the 3, 5, 7, 9 interstices ; posterior band has 

 before and behind obtuse denticulations, which correspond 

 roughly to the teeth of the anterior band. The apical spot is 

 trigonal, with notches in the edge farthest from the apex of the 

 elytron. The suture is black to the extent of the first interstice, 

 and the elytral striae and punctures do not present any specific 

 characters, but resemble those in holeti, Linn., and leivisi, Bates. 

 The prosternum is rather broad, without the definite lateral 

 margination of leivisi, and it has a small medial tubercle at the 

 anterior edge, which is evidently a continuation or culminating 

 point of the anterior margin. In lewisi the space between the 

 eyes is half the width of that in ni'ponensis, and, roughly speaking, 

 the same may be said of the prosternum. In n'q^onensis the 

 antennae are broader, especially the apical joints. 



The species is comparatively rare ; I took it at Sapporo and 

 Junsai in Yezo, and at Fukushima on the main island; but 

 I obtained only twenty specimens altogether. 



Since tlie date of Mr. Bates's paper Diaperis lewisi has been 

 found in Siberia, and has been taken in all the Japanese Islands. 

 The original specimens came from Fungi on some old posts on 

 the bund at Nagasaki, and on the 30th June, 1880, I saw it in 

 profusion at Sliiba in Tokio under similar conditions.

ON A NEW SPECIES OF PHELLOPSIS FOUND IN JAPAN 



AND SIBERIA. 



By George Lewis, F.L.S. 



Several species of Nosoderma have been described lately by 

 •Mr. Champion, and he has pointed out to me that in Nosoderma 

 the last two joints of the antenna are connate, but in Phellopsis 

 the last three joints are free and somewhat lax. This seems a 

 sufficient character for a generic distinction, although in the 

 Munich Catalogue the species are all included in Nosoderma. 

 Most of the species of Nosoderma have been found in Mexico 

 and Central America, while those of Phellopsis are two from the 

 United States, and the present species from the western side of 

 the Pacific.
