82 Mr. David Sbarp on the 



Phyllohius in each, and the possession by Japan of 

 a species of Scythropus allied to the European 

 S. mustela. 



I very much regret the delay that has occurred in the 

 preparation of this paper, which was commenced several 

 years since ; and also that I shall not be able to continue 

 the work for some time to come. But I hope that 

 Mr. Lewis, who besides forming his splendid collection, 

 has himself done so much towards working out the 

 insects he procured, may be able to complete our know- 

 ledge of the Curculionidse. 



OTIORHYNCHID^. 



This term I use in the sense of Leconte and Horn, 

 classification of Col. of N. America, 1883. It is very 

 different fi'om the Otiorhynchides of Lacordaire. I have, 

 however, admitted an exception in the case of the genus 

 Meotiorhy iichus, which does not possess the scars on the 

 mandibles, that is the special character of the family 

 OtiorhyncJiid^e, accordiug to the American taxonomists. 

 I adopt two divisions, Otiorhynchidie apterx and 0. 

 alaf^e, which, practically, are almost equivalent respec- 

 tively to the Divisions I. and IT. of the N. American 

 writers, as explained in the Biol. Centr. Amer., Col. IV., 

 pt. 3, p. 87. 



OTIORHYNCHID^ APTER^. 



This division was not recognized as distinct from the 

 winged forms by Lacordaire, consequently its members 

 were distributed throughout the Brachy derides and 

 Otiorhynchides of the Belgian naturalist in so complex 

 a manner as to render the application of his nomen- 

 clature to the divisions proposed by Leconte and Horn 

 almost impossible. At the same time I do not know 

 enough of the forms dealt with by the American 

 naturalists to enable me to judge whether the Japanese 

 wingless Otiorhynchidae would enter satisfactorily into 

 their divisions, and I therefore adopt the plan of 

 arranging the sixteen genera that have been discovered 

 in Japan in the following manner : —
