This Elater agrees in many respects with E. rubridorsus, 

 Lew., but in the latter the thorax is much more strongly 

 punctured, the interstices of the elytra convex, and there is a 

 fovea between the eyes.

This species was given to me on the supposition that it 

 came from Tsushima ; the correct locality is Tangiers. It 

 is a good species, and differs from Elater sanguinolentus^ 

 Schrank, in having a more convex tliorax and more robust 

 antenna? and tarsi. The type specimens are now in the 

 British Museum. 



Elater chlami/dafus, sp. u. 



E. montano simillimus, sed thorace magis elongato ; scutello cordi- 



formi ; elytris interstitiis rugosis ; antennis pedibusque nigris. 

 L. 9J mill. 



Black, shining, with long black pubescence ; the head 

 evenly, not coarsely nor thickly punctured ; the thorax rela- 

 tively longer than any in this series, with red elytra, narrowest 

 in front, broadest at base, very finely punctured except at the 

 anterior angle and in the interstice of the margin and the 

 basal carina ; the elytra dull red, punctate-striate, interstices 

 transversely rugose, apex narrowly infuscate ; the antennje 

 and legs densely black, third joint of former scarcely longer 

 than the second. 



Very similar to E. montanus. Lew., but the length of the 

 thorax and rugose interstices serve to distinguish it, as well 

 as the form of the scutellum and the basal joint of the 

 antennas. 



Hah. Kadzusa, an island off Yokohama. One example. 



Elater montanus, sp. n. 



Atcr, nitidus, longius nigro-pubesceiis ; thorace subtiUssimo punctu- 

 hito ; elytris brunueo-rutis, apicc minute iafuscatis ; antennis 

 pedibusque nigris. 



L. 8-1)=^ mill. 



Densely black, shining, with long black pubescence; the 

 head clearly, rather linoly, not closely punctured, frontal carina 

 depressed in the middle ; the thorax not opalescent, very 

 finely punctured (much more so than the head) on the disk,'
