the Elateridai of Japan. IWI 



This very ili:^tinct species is narrower tlian G, sequens^ 

 Caml. ; the scutellum more cordate and the interstices of the 

 elytra densely rugose. 



Hub. Subashiri. One individual only. 



Cardiophorus ferrugineus, sp. n. 

 Cardiophonu sobrt'niis, Cand. M^m. Liege, 1873, p. 17. 



Ferruginous, nitidus, albo-pubescens ; capitc c:rosso punctato ; 



thorace panim dense punctulato haud canaliculato ; anteunis 



pedibusquo concoloribus. 

 L. 7| mill. 



Ferruginous, shining, with whitish pubescence ; the head 

 rather roughly, coarsely, and densely punctured except on a 

 very small space between the eyes, frontal carina arched 

 anteriorly and distinctly angulate before the eyes ; the thorax 

 very finely but very evenly ])unctulate throughout, not cana- 

 liculate in the middle, rather parallel at the sides, hind angles 

 obtuse and nearly straight ; the scutellum, anterior fovea 

 scarcely visible ; the elytra punctate-striate, interstices con- 

 vex ; the antennae and legs ferruginous, claws not strongly 

 dentate. 



Agrees in colour with C. sobrinus, Cand., but the frontal 

 carina is formed differently, head coarsely punctured, thorax 

 without a canaliculation, and the claws much less strongly 

 dentate. In C. sobrinus the scutellar fovea is large and deep. 

 This species, with C. pauper, nothus, rameus, and adjutory 

 belongs to Cand^ze's Section II. with dentate claws.

Melanotopsis, gen. nov. 



This genus is founded to receive several species it does 

 not seem desirable to leave in Melanotus. Both genera are 

 alike in general characters, but the keel of the prosternum in 

 3/e^wotojos/s is continued horizontally behind the coxte (wood- 

 cut, fig. 2, |, coxal cavity), not obliquely, nor vertically as 



it is in some species of Melanotus, and the posterior prosternal 

 process is received into a cavity in the mesosternum cut out 

 in the form of a V (fig- l)j not gradually shelving like that 

 in Melanotus. I consider Melanotus cete, Cand., the type of 

 the new genus, and it is from this species the drawings 

 are made. M. restrictus and M. regalis, Cand., must also be 

 transferred to it.
