Bhynchophorous Coleoptera of Japan. 85 



About twenty examples of this species were found at 

 Hakodate : most of them agree with M. Roelofs^ descrip- 

 tions satisfactorily ; but five of them belong to a well- 

 marked variety, in which the upper surface is almost 

 uniform pallid grey, the maculation of the elytra and 

 thorax being nearly absent. Scarcely any two specimens 

 of the type-form agree exactly in the maculation. 



2. Copanopachys griseus. 



Piazomias griseus, Roelofs, op. cit., xvi., 1873, p. 162 ; 

 G. griseus, id., xxiv., p. 8. 



I have before me about a score of examples that I 

 refer to this species, though they vary enormously 

 in colour, greatly in size, and somewhat in minute 

 structural characters. All, however, differ from C. 

 tigrinus, in having the eyes more convex, and the front 

 tibige not in the least dilated externally at the apex. 

 One of them in colour exactly resembles the typical form 

 of G. tigrinus, while on the other hand, the smaller 

 examples are wonderfully like Scepticus insularis. 



Main island; Enoshima, Kawatchi, Yokohama (in April), 

 Kobe. One specimen from each locality. The others 

 were all obtained during Mr . Lewis's earlier visits, and 

 the localities have not been preserved, but, no doubt, all 

 are from the islands south of Yezo, while 0. tigrinus is — 

 so far as we know at present — confined to that island. 



Meotiorhynchus, n. gen. 



MandibulfB ad apices tranversim laminataj ; tibije anteriores 

 apicibus dilatatis. 



Mandibles at the apex, forming as it were a prominent lamina, 

 the front edge of which is quite thin and the outer angle 

 the most prominent part ; without scar; nearly similar to one 

 another : buccal cavity large, filled by the mentum. Rostrum 

 short, scrobes definite and deep, lateral and descending. An- 

 tennae short, scape broad at the extremity, 7th joint of the 

 funiculus almost amalgamated with the club. Eyes oval, moder- 

 ately distant from the thorax. Prosternum a little emarginate, 

 front margin irregularly ciliate, the cilite below the eye longer, so 

 as to form rudimentary vibrissse. Metasternum short. Hind coxae 

 widely separated, the intercoxal abdominal process being broad 

 and truncate. First and second ventral plates elongate, third and
