106 Mr. David Sharp on the 



ScYTHROPUS, Schoulierr.

 1873, p. 179. 



Yokohama : four specimens. This insect is apparently 

 really congeneric with the European 8. mustela ; it has, 

 however, the front of the rostrum differently formed — as 

 pointed out by M. Roelofs — and, in addition to this 

 distinction, the remarkable fringe of sette on the outside 

 of the apical portion of the hind tibia is wanting in the 

 Japanese species, 



Macrocorynds, Schonherr. 



1. Ilaci'ocorynus discoidei)s, 01., Roelofs, Ann. Soc. ent. 

 Belgique, 1873, p. 167. 



This E. Indian species was not found in Japan by 

 Mr. Lewis during his last visit. Previously the species 

 was only met with at Kagoshima, so that it is probably 

 confined in Japan to the extreme south. 



Myllocerus, Schonherr. 



Six species of this genus, all peculiar to Japan, have 

 been described by M. Roelofs, and I now add three 

 others. M. ahnormalis might, however, be placed in 

 Macrocorynus with as much propriety as in Mi/Ilocerns. 



1. Mijllocerns naso, n. sp. 



Densissime squainosus, brunneus, in elytris vage pallide-varie- 

 gatus, caplte inter oculos canaliculate. Long. 7 ram. 



Very distinct from the other Japanese Mylloceri, and 

 more closely allied to the Siberian M. sibiricus, Tourn. ; 

 readily distinguished by the structure of the apex of the 

 rostrum ; the depression of the nasal plate being much 

 prolonged on to the rostrum, and forming above a very 

 acute angle, surrounded by a remarkably deep and definite 

 angular groove, which is prolonged as a fine smooth 

 space along the middle of the rostrum, becoming more 

 deeply impressed between the eyes, so as to form a short 

 channel there. Scape long, rather densely setose, 2nd 

 and 3rd joints of antenna very long, club elongate.
