the Elatcridaj of Japan, 265 



Say, but otherwise very similar to it ; the hitter, however, 

 has iiu smooth median line on the thorax.

L. 24 mill. 



Elliptical, eloni:;ate, black, with brown pubescence ; an- 

 tenniu and legs pitchy red ; the head oblif[ue at the sides 

 before the eyes, truncate before the epistoma, punctate, punc- 

 tures rather small and somewhat closely set ; the thorax 

 narrowest in front, gradually widening to base, very feebly 

 sinuous before the angles, carinas well raised and oblique, thus 

 leaving anteriorly a wide interstice, excavated transversely at 

 base ; the scutellum distinctly convex but nearly vertical ; the 

 elytra elongate, gradually narrowing to apex, feebly striate, 

 interstices punctulate and somewhat finely rugose ; the 

 prosternal posterior process is very long and the notch is 

 close to the tip ; the antennae, terminal joint constricted, third 

 joint one third longer than the second. 



I have only seen one example of this curious species. The 

 form of the forehead and the oblique direction of the thoracic 

 carinas, the convex scutellum, and the length of the prosternal 

 process are very peculiar. I have much pleasure in naming it 

 after Dr. M, E. (Jandcize, the author of the ' Monograph on 

 the Elateridse ' and of the first memoir on the Japanese species. 



Hab. Nagasaki.

In this species the prosternal notch is not quite so con- 

 spicuous as in L. ferrugmeus, L., but it is well-marked (see 

 fig. 3, t , coxal cavity). 



Hab. Nagasaki, Kobd, and Sapporo. Twenty examples.
