Genus and Species of Long worn Coleoptera. 309 



behind, and canaliculate in the middle near the base. Elytra 

 slightly depressed and canaliculate along each side of the 

 scutellum, rounded at the apex. Legs increasing in length 

 from the first to the third pair ; femora stalked at the base, 

 thickened into a fusiform club between the middle and the 

 apex. Intercoxal part of prosternum furnished with a down- 

 wardly-directed conical tubercle ; mesosternum with a large 

 subcylindrical process, which projects downwards for some 

 distance below the level of the cox^. 



This genus must be placed in Lacordaire's " groupe " 

 Stenasjndes. In many of its characters it seems to come 

 nearest to Euryphigus, Thoms., but in the structure of the 

 head it is quite different, being in this respect very like the 

 genus Pkilagathes, Thoms. 



Dicelosternus corallinuSy sp. n. 



llufus ; prothorace opaeo, disco valde elevate et punctato-rugoso, 

 versus marginem anticum et ad latera plus miausve transversim 

 rugoso, lateribus pone tuberculos sat abrupte constrictis, et ab 

 tuberculis usque ad marginem anticum gradatim convergentibus ; 

 scutello elongato, postice acuminato, supra ad basin canaliculato ; 

 elytris rufo-politis, fere impunctatis, fascia transversa nigro- 

 velutina pone medium ; pedibus rufo-nitidis, coxis geuubusque 

 uigris, antennis articulis 3*^ ad 7""^ apice, et sequentibus fere totis, 

 nigris. 



Long. 21-27, lat. 8-10 mm. 



Hah. Central Formosa {Hoist). 



Almost entirely of a bright reddish colour, the prothorax 

 being rugosely sculptured and opaque, and the rest of the 

 body, including the legs and elytra, more or less highly 

 polished. A little behind the middle of the elytra there is a 

 transverse band, narrowed near the suture, made up of short 

 black hairs springing from small and very closely placed 

 punctures, these punctures being easily seen under a lens 

 near the edges of the band ; the rest of the elytral surface is 

 almost Avholly impunctate. The coxse, trochanters, and the 

 tips of the femora and tarsal joints are black, and there is a 

 fringe of short black hairs on the upperside of the hind femora 

 ' in the middle third of their length. The third and succeeding 

 joints of the antennse are blackish at the apex and, to a greater 

 or less extent, along the anterior border, the last three or four 

 joints being almost entirely dark brown.
