Megapenthes gracilis^ Cand. 

 Megapenthes gracilis, Cand. M6m. Liege, 1873, p. 10. 



The males of this species are very different to the females ; 

 the thorax is longer, more parallel, and usually infuscate, 

 punctures thickly set and finely ocellate ; the antennae also 

 darker, with joints 4-11 one third longer. 



L. 7-8^ mill. 



Hab. Kiga, Yokohama, Kioto, and Kumamoto. Abundant 

 at times in flowers of Vihurnum and Deutzia. 



Megapenthes pallidus, sp. n. 



Elongatus, testaceus, subopacus, fiilvo-pubescens ; thorace latcribus 

 parallelis, angulis posticis brevissimis ; antennis pedibusque con- 

 coloribus. 



L. 7 mill. 



Elongate, pale testaceous, rather opaque, and similar to 

 M. gracilis, Cand., but the hind angles of the thorax are very 

 short, the sides very parallel ; the head not densely but 

 clearly punctured ; the thorax less distinctly punctured, wider 

 behind than in front, sides straight, angles very short and 

 blunt; the elytra punctate-striate, interstices rugose and 

 punctulate ; the antennas and legs concolorous, the former 

 with the third joint distinctly one third longer than the second, 

 which is short and obconical. 



Hab. Nataksugawa and Nikko. Three individuals only. 



Megapenthes insignitus^ sp. n. 



Aterrimus, subopacus, fulvo-pubescens ; capite thoraceque confer- 

 tissimc punctatis ; elytris 4-maculatis ; autcnnis bniuneis ; 

 pedibus testaceis. 



L. 5|-6 miU. 



Black, somewhat opaque, with a tawny pubescence ; the 

 head and thorax very closely punctured ; the elytra, behind 

 the humeral angle there is a longitudinal testaceous blotch, 

 nearly the lengtli of one third of the elytra, occupying part of 

 interstices o-8, behind the middle is an oblong spot a little 

 smaller in size on interstices 3-7, the striae are evenly ))unc- 

 tate, with the interspaces rugose ; the antenniv; darkish brown, 

 the legs testaceous. 



There is a variety in which the maculatious are very small. 



Hah. Miyanoshita and Yokohama. A small series at both 

 places.
