tennis pedibusque flavis ; elytris fuMs, margine exteriore nigro ; 

 thorace pareissime punctato, elytris parce subtiliterque granulatis. 

 Long. 2| millim. 



Antennge short, clear yellow, fourth joint small, fifth to 

 tenth similar to one another, each transverse. Head broad 

 and short, almost impunctate. Thorax strongly transverse, 

 narrower than the elytra, with three or four punctures on 

 each side of the middle, forming an irregular series. Elytra 

 a little longer than the thorax, bearing distant, minute, 

 flattened granules. Hind body very finely and distantly 

 punctate. In the male there is a series of very minute granules 

 extending across the penultimate dorsal plate just in front of 

 the hind margin ; the terminal plate bears some coarser flat 

 granulations irregularly placed, and its hind margin forms a 

 triangular prominence. 



Sapporo ; three specimens. 



In addition to these two species Mr. Lewis's collection con- 

 tains a third Gyrophcena of very pallid colour ; but the 

 examples are not in a fit condition for examination. 



Myllcena japonica^ n. sp. 



Elongata, angusta, omnino subtilissime punctulata, opaca, fusco- 

 ferruginea ; antennis palpis pedibusque testaceis ; thorace trans- 

 verso, basi utrinque leviter sinuato ; elytris illo paulo longi- 

 oribus. 



Long. 3 1 millim. 



Antennse very slender, scarcely any thicker externally, 

 tenth joint much longer than broad. Head about half as 

 broad as the elytra. Thorax nearly twice as broad as long, 

 convex transversely, much narrowed in front, the punctuation 

 excessively minute, the base a little sinuate on each side near 

 the hind angles, these rectangular. 



Nagasaki and Miyanoshita, in April and May. 



This is similar in size and colour to the European M. elon- 

 gata^ Rey, but has more slender antenna, and its thorax more 

 transverse and distinctly sinuate at the base on each side.
