Coleoptera of Japan. 67 



Rhynchites apionoides, n. s. 



Minor, cyaneo-niger, brevissime pubescens ; capite angusto ; 

 prothorace parvo, ruguloso ; elytris subtiliter seriatim piinctatis, 

 interstitiis baud convexis parce subtiliter punctatis. Long, cum 

 rostro, 3^ mm. 



Rostrum moderately stout, scarcely longer than the thorax ; 

 head narrow, rather long, coarsely and sparingly pmictate. Thorax 

 much narrower than the elytra, a little rounded at the sides, about 

 as long as broad, rugose. Elytra with series of rather fine 

 punctures — towards the apex qivite fine — the interstices broad, 

 quite flat, sparingly almost seriately punctate. Legs short. 



An obscure little insect, not closely allied to any other 

 species ; the difference between the sexes seems very 

 slight. 



Plain of Fujisan. 



Rhynchites singularis. 



Rhynchites singularis, Eoelofs, Ann. Soc. Ent. Belg., 

 xvii., p. 147. 



Although so peculiar in colour and clothing, this 

 species seems structurally near R. conicus. 



Rhynchites truncatus, n. s. 

 Brevis, pube brevi, depressa vestitus, niger, prothorace sub- 

 senescente, elytris plumbeo-cyaneis, capite laetius aenescente ; dense 

 punctatus ; prothorace lato, ocuhs prominuUs. Long, cum rostro, 

 4 mm. 



Antennae black, with broad moderately long club. Rostrum 

 rather longer than the thorax. Head large, eyes prominent, 

 widely separated, distant from the thoracic margin, the vertex 

 rather closely punctate. Thorax broad, but much narrower than 

 the elytra, subcircular, densely punctate. Elytra with very 

 regular series of moderately coarse punctures, the interstices 

 rather convex, sparingly punctate. Pygidium exposed ; legs 

 rather short, the suture between the first and second ventral 

 segments excessively deep. 



This is a very peculiar species, and appears to con- 

 nect R. tristis with the more typical forms of the genus.
