cessful method of obtaining the Dyschirii, recorded in the 

 Zoologist (p. 1671). 



Dysckirius elongatulus. Head black, narrow, the whole 

 surface above the mouth depressed and somewhat rugose, 

 having a distinctly raised emargination on the anterior 

 border, and a second transverse elevation behind like a little 

 band, also a deeply impressed longitudinal fovea on each 

 side behind the eyes, which gives them the appearance of 

 considerable prominency; antennae ferruginous, their basal 

 joints and those of the palpi brighter red. Thorax shining 

 black, as broad in front as the head, including the very pro- 

 minent eyes, and increasing in width till behind the middle, 

 strongly rounded and globose behind where the posterior 

 angles should be ; disk very convex, especially behind, 

 dorsal furrow fine and transversely strigose, terminating in 

 front in a distinct transverse impression, and behind (where 

 it becomes deeper) in another depressed space, which ap- 

 pears like a transverse collar or band, which is closely 

 striated longitudinally. Elytra brassy black, elongate, twice 

 as long as the thorax, narrow and cylindrical, not attenuated 

 at the apex but merely rounded ; punctate-striated, the punc- 

 tures distinctly impressed as in salinus, deepest in front and 

 gradually fainter towards the extremity; the punctures of the 

 fourth and fifth striae are however distinct till they terminate 

 before the extremity, and are succeeded by a smooth stria 

 which is carried obliquely to the tip ; the three exterior punc- 

 tured striae are very fine, terminating at the shoulder, two 

 of them abbreviated and united behind, but the lateral one, 

 although abbreviated likewise, is succeeded after a little in- 

 terval by a more deeply impressed smooth stria, which also 

 tends obliquely towards the tip exterior to the other one 

 above-mentioned, and with it forms a kind of loop ; under- 

 side black, legs reel, anterior tibiae unarmed. Length 2| 

 lines.
