Melanotopsis cete. 



Melanotus cete, Cand. Mon. El. iii. 1860, p. 332. 

 Melanotus amussitatus, Cand. M6in. Liege, 1873, p. 19. 



A comparison of specimens in the Janson collection enables 

 me to give the above synonymy. 



Hab. Nagasaki, Kob^, and Yokohama. Common. 



Melanotus longipennis, sp. n. 



M. legato simillimus, sed diflfert thorace relative lato ; elytris magie 



elongatis ; prosterno grosse et profunda punctato. 

 L. 18-21 mill. 



This insect closely resembles M. legaius, Cand., in colour, 

 pubescence, articulation of the antennje, and in the falciform 

 anterior tibia? ; but the thorax is wider, especially before the 

 middle, punctuation more dense, the scutellum broader, the 

 elytra more elongate, and, above all these ditferences, the pro- 

 sternum has very large and deep punctures, some of the 

 punctures being ocellate. 



Bah. Koh4 and Kioto. Three examples, and there is 

 another in the Janson collection \Yhich is larger than any of 

 mine. 



Melanotus spernendus, Cand. 

 Melanotus spernejidus, Oand. M6m. Liege, 1873, p. 21. 



I ]ilace this species next to M. legatus, Cand., although the 

 facios of the species is very dissimilar ; the anterior tibije are 

 falciform and the declination of the prosternal process and 

 somewhat widening out of the keel between the coxae are 

 characters which bring them together. 



Jfah. Nagasaki, liitoyoshi, and Ynyania. Twelve ex- 

 amples.
