98 Mr. David Sharp on the 



1. Phyllobius longicornis. 



P. lonqlcovnh, Eoelofs, Ann. Soc. ent. Belgique, xvi., 

 p." 106. 



The male of the insect I identify as tliis species, has 

 the trouf^h, or gouge-shaped depression, on the terminal 

 ventral plate very deep, and the preceding two segments 

 are more or less deeply, broadly impressed; the first 

 abdominal segment is only shghtly impressed on the 

 middle, and the metasternum has no angular prominence 

 on either side of the median impression. The front 

 tibia) have only a slight sinuation of the inner margin 

 below the middle ; the hind tibise have a very feeble 

 concavity of the inner face of the apical part. The head 

 has only a slight swelling of the surface posterior to the 

 eyes. The antennae are very long ; the upper surface of 

 the insect is rather densely covered with minute green 

 scales, and there is no long pubescence. 



M. Roelofs did not at first distinguish between this 

 species and P. lyrolonrjatus, and most of his specimens 

 in the Lewis collection belong to the latter species. 

 Altogether I have examined eight specimens of P. longi- 

 rorui.s : the localities are Nikko, Yokohama, Oyama, and 

 >\livanoshita, on the Main island; Hakodate inYezo. 



2. P/tijIIohius prolongatus: 



P. prolongatus, Motsch., Bull. Soc. Moscow, 1866, i., 

 p. 180. 



I accept, as representative of this species, an individual 

 in Mr. Lewises collection, determined by one of the 

 German authorities who examined Herr Killer's Japanese 

 Coleoptera. 



P. prolongatus is closely allied to P. longicornis, and 

 is densely covered with golden-green scales, but has 

 the male characters much less remarkably developed, 

 the depression of the last ventral plate being com- 

 paratively slight, and the preceding two segments being 

 simple; the tooth of the front femur is considerably 

 smaller, and all the femora are less swollen. In the 

 female the ventral segments are more bare than they are 

 in P. lungicornis.
