set with fine pale pubescence, on either side of which are 

 black seta3. 



This is nearer than any other of the Japanese species to 

 our European M. splendidus^ but is not very close to it.

Mycetoporus dupUcatus^ n. sp. 



Ruf 0- testaceus ; elytris nigricantibus, basi late rufo-testa ceo, serie 



suturali multipunctato, serie dorsali duplicato. 

 Long. 5 millira. 



Antennse moderately long, penultimate joints scarcely so 

 long as broad. Head yellow, slightly infuscate. Thorax 

 clear yellow, broader than long. Elytra rather elongate, 

 more than lialf of their surface black, the base being clear 

 yellow ; the punctures of the sutural series are numerous and 

 distinct, about fifteen in number ; the dorsal series is dupli- 

 cate. The hind body is clear pale red, rather closely punc- 

 tate. The legs are yellow. 



Chiuzenji, 2 1st August, 1881 ; two examples. 



Mycetoporus Lewisius. 

 Bryoporus Lewisius, Sharp, Trans. Ent. Soc. Loud. 1874, p. 19. 



Mr. Lewis has now obtained other specimens of this insect, 

 and it is clear from the structure of the palpi that the species 

 would be better placed in the subgenus Ischnosoma of Myce- 

 toporus than in Bryoporus. This species and M. duplicatus 

 connect, however, Mycetoporus rather closely with Bryoporus. 



Nagasaki in April ; four examples.
