cealed. Thorax linear, extremely finely punctured, with a faintly 

 impressed line posteriorly; the angles well produced and acute, 

 forming a sharp ridge at the base ; pectoral spine long, acute and 

 grooved at the base. Elytra not broader than the thorax, but 

 more than twice as long, slightly glossy, rather thickly punctured 

 and striated ; the striae close together and rough at the apex, 

 which is emarginate. Legs very slender, knees slightly ferrugi- 

 nous; tarsi simple; claws ochreous. 

 5 lines long, li broad. 



This fine and very distinct insect does not agree with any of 

 the genera with which 1 am acquainted, but for the present I 

 have placed it with Eclinus? rather than run the risk of imposing 

 a generic name unnecessarily. I have only seen the specimen in 

 my Collection, which was taken at Windsor, and another foreign 

 one in the British Museum. ]Mr. Stephens, relying on his me- 

 mory, has unluckily applied Paykull's descriptions of Elater ni- 

 grinus? to this insect, with points of doubt which were most ne- 

 cessary, for they do not agree in any way, nor belong even to the 

 same genus. Our insect is not shining; the antennae are not so 

 long as the thorax ; the tarsi are not pale, and it is very much 

 longer than Elater b'lpustulatus, which PaykuU gives as the size of 

 E. nigrinus. 



Sp. 3. N. G.? pitncto-Iineatus, Zool. Journ. iv. 524; aterrimtis, 

 Stephens' Cabinet. (PI. II. fig. 3.) 



Robust, elliptical, very convex, slaty-black, glossy but dull, 

 being clothed with very short ochreous pubescence. Antennae 

 scarcely so long as the thorax (fig. e) ; basal joint small but stout; 

 second and third globose, the following compressed and subser- 

 rated, the joints being obtrigonate. Head and thorax thickly and 

 firmly punctured; clypeus short, scarcely convex in front and not 

 margined, projecting and not drooping over the mouth (fig. /). 

 Thorax semiovate, considerably broadest at the base, with a 

 smooth line down the centre, the angles forming triangular lobes, 

 not acuminated but slightly clawed ; pectoral spine rather short, 

 compressed and not concave at the base, scutel depressed, semi- 

 oval. Elytra a trifle broader than the thorax, and twice as long, 

 minutely punctured and firmly striate-punctate. Legs stout, 

 tarsi simple, compressed, brownish, tawny at the extremity. 



Gg lines long, 2 lines broad. 



This is the Elater puncto-Uncatus, as referred to above, in the 

 Zoological Journal. Mr. Stephens, in his Illustrations, refers
