fine cinereous pubescence, as in C. gagates, from which it 

 differs chiefly bj its less convex prothorax and elytra, and less 

 rounded sides of prothorax. 



Elatee. 

 / Elater anthracinus. 



Niger, nitidus ; pube brevi siiberecta nigra parce vestitus, prothorace 

 latitudine longiore, antice angustiore, angulis posticis elongatis, 

 fortiter carinatis ; disco convexo, fortiter sat dense punctato, 

 punctis hand -umbiheatis ; elytris striis punctatis, interstitiis vix 

 eonvexis, punctatis, et transversim subrugosis ; tarsis piceis ; an- 

 tennarum articuhs 2^° et 3*'® conjunctis sequente paulo longi- 

 oribus, hoc 2^° vix latiore. 



Long. 10 millim. 



One pair. In the male the prothorax is narrowed from the 

 base to the apex, with the sides broadly and obliquely rounded ; 

 in the female the sides are nearly parallel behind the middle 

 then rounded to the tip, and the elytra are more obtuse behind 

 than in the male. This species is allied to E. carhonicolor 

 but is much larger, the prothorax is more strongly punctured 

 and the third joint of the antennae is narrower. It also ap- 

 proaches very nearly to an Alaskan specimen of E. nigrinus 

 which, however, has the hind angles of the thorax acutely 

 not feebly carinate, as described by Cand^ze, Elat. ii. 475 

 it differs by its larger size and greater length of the third 

 joint of the antennae, which is distinctly longer than the 

 second, and by the somewhat more elongate form, longer hind 

 angles of the thorax, and black antennas and feet. 



LiMONIUS. 

 ^Limonius nitidicollis. 



Nigro-seneus, nitidus, parce breviter nigro pubescens ; fronte apice 

 late rotundato, margine anguste reflexo, inter antennas biira- 

 presso ; capite thoraceque parce distincte punctatis, hoc latitudine 

 paulo longiore, antice vix angustiore, convexo, angulis posticis 

 acutis, reflexis, carina brevi margini approximata, minus con- 

 spicua, basi medio brevissime canaliculato ; elytris striis subtih- 

 bus impunctatis, interstitiis plan is, biseriatim punctatis ; anten- 

 narum articulis 2^° et 3''° seqaalibus, conjunctis 4*° paulo longi- 

 oribus. 



Long. 6 millim. 



One pair. Similar in size and form to L. querdnus, but 

 very different by the characters given above, and rather 

 allied to L. aurifer^ Lee, though quite distinct from that 

 species.
