20 C. Agassii. — Niger, thorace valde rugoso, latitudine paulo breviore, quadrate, pos- 

 tice leviter angustato, margine versus basin anguste reflexo, angulis basalibus retror- 

 Bum productis, elytris thorace sesqui latioribus ellipticis, dense seriatim punctatis foveis- 

 que parum distinctis 3-plici serie impressis. Long. "SB. 



Kakabeka— Dr. Stout. At first sight seems to be a faded specimen of C. sylvosus 

 (Say), but the thorax is very rugous, the sides more narrowly reflexed, and the basal 

 angles much more produced. The sculpture of the elytra is similar, but more distinct. 

 It is more closely allied to C. tadatus (Fabr.), from Oregon, but the head is less im- 

 pressed, and the elytra less deeply foveate, with the sides regularly but slightly round- 

 ed, not straight and narrowed anteriorly as in C. tsedatus. Anything that I can say in 

 praise of the philosopher and gentleman after whom it is named would be quite super- 

 fluous. 



'^^ N. moesta. — Depressiuscula nigra nitida, thorace latitudine duplo fere breviore la- 

 teribus marginato, valde rotundato, postice valde angustato, constrictoque, angulis pos- 

 ticis rectis, antice posticeque transversim profunde impresso, punctatoque, impress, 

 basalibus profundis : elytris subparallelis thorace latioribus striis leviter punctatis, 8^a 

 fere obliterata, interstitio 3'° o-punctato : antennarum apice tibiis tarsisque rufo- 

 piceis. Long. •41. 



This maybe Kirby's Helobia castanipes (which I incorrectly cited as N. pallipes Say), 

 as Dr. Schaum writes me it is very like N. Gyllenhalii, to which our insect has the 

 closest resemblance. My specimens have not the strife between the eyes mentioned by 

 Kirby, nor are the feet castaneous: the margin of the thorax is sometimes obsoletely 

 punctured. 



*- N. suturalis. — Elongata depressa, nigra, thorace latitudine fere duplo breviore, lateri- 

 bus marginato, margine postice latiore, rotundatoque, basi angustato non constrieto, an- 

 gulis posticis obtusis, basi truncate, cum margine obsolete punctato, antice posticeque 

 profunde transversim impresso, elytris elongatis thorace latioribus obscure rufis, sutura 

 nigricante, striis leviter punctatis interstitiis fere planis, 3'o 5-punctato, antennis tibiis 

 tarsisque rufo-piceis vel rufis. Long. -44. 



The 8th stria is less deep than the others, but not obliterated ; the punctures in the 

 marginal series are more numerous than in the preceding. Found on the islands at 

 the mouth of Black Bay. 



23 E. politus. — Obscure seneus, politus, capite sparsim punctato, vertice foveato, oeci- 

 pite profunde impresso ; thorace capita non latiore antice angulatim valde impresso, 

 dein canaliculato, disco utrinque profunde foveato, ad latera apicem basinque sparsim 

 punctato ; elytris sparsim punctulatis foveis ocellatis purpureis 4-plici serie impressis, 

 pedibus rufo-seneis ; ante-pectore punctato. Long. -34. One specunen : Maple Island. 

 Dr. Stout.
