Melanotus caudex^ Lew. 

 Melanotus caudex, Lew. Ent. Month. Mag. 1879, p. loO. 



Very similar to M. erythropycjus ^ Cand., in facies, but the 

 declination of the posterior prosternal process is almost vertical 

 beliind the coxge, and in this respect agrees with M. seniculus, 

 Cand. The second and third joints of the antenna are small, 

 bulbous, and equal in length, tarsi somewhat short and robust, 

 and the median smooth line on the thorax is more plainly 

 seen in the female than in the male. 



Hah. Kumamoto and Wakajama. Ten examples. 



Melanotus seniculus, Cand. 



The elytra are usually pale in this insect and the declina- 

 tion of the posterior prosternal process is nearly perpendicular. 

 Hab. Nagasaki and Yokohama. 



Limonius niponensis^ sp. n. 



Obscure asneus, nitidus, griseo-pubesccns ; fronte ocellato-punctata 

 hand cmarginata ; thorace couvexo, punetato ; antcnnis pedi- 

 busque nigris. 



L. 12 mill. 



Obscurely seneous, shining, pubescence grey ; the head 

 slightly depressed between the antennas, carina anteriorly 

 straight, densely punctured, punctures deep and somewhat 

 ocellate ; the thorax clearl}', closely, and deeply punctured, 

 punctures microscopically ocellate, disk convex, angles short 

 and blunt ; the scutellum densely punctulate, pubescent ; the 

 elytra punctate-striate, interstices flat, rather wide, and 

 sparsely punctulate ; the antennae black, second and third 

 joints rather long and equal ; the legs black, knees and claws 

 pale, tibiffi stouter than those of L. montivagus. 



Motschulsky (Bull. Mosc. 1866, p. 166) records the capture 

 oi Limonnis cylindncus^ Payk., in Japan. I think he refers 

 to this species, as it closely resembles it, and I have rejected 

 L. cylindricus from the list. 



Uah. Junsai. 



Limonius montivagus^ sp. n. 



Obscure ivncus, nitidus, fulvo-pubcsccns ; frouto carina conspicue 



I'lovata ; thorace douse punetato ; tibiis tarsisque Havis. 

 L. 9 mill. 



Obscurely leneous, shining, with yellowish tawny pubes- 

 cence; the head convex, densely punctate, frontal carina bent
