28 THE CANADIAN ENTOMOLOGIST. 



93. Haliplus Impressus, Latr. — One specimen taken in Lat. 65". 

 Length of body 1 1 / 2 lines, nearly. 



[66.] Body, reddish-yellow. Head punctured, dusky behind: prothorax 

 yellow, depressed in the middle posteriorly, with a transverse curved series 

 of punctures in the depression ; anteriorly there are five or six black dots 

 arranged transversely ; at the base, between the central point and the 

 margin on each side, an oblique little furrow, but not easily discoverable, 

 is impressed : elytra pale-yellow, with a cinereous tint, nine rows of black 

 punctures on each, those near the lateral margin being the faintest ; 

 anteriorly, in the interstices of the rows, there are also a few black punc- 

 tures ; the apex of the elytra is oblique, terminating in an acute point: the 

 laminae that cover the posterior legs are punctured. * [Kirby is doubtful 

 respecting the identity of this specimen with Latreille's species, as though 

 the latter's description agrees with it, his figure does not, for it represents 

 the elytra with eight black spots, which are not to be found in II. Impressus. 

 Le Conte puts it down as a probable synonym of H. ImmaculicoUis, Harris, 

 a species taken in Canada, and regards its identification with Latreille's 

 species as erroneous.] 



94. Hvdroporus Nicro-Lineatus, Stephens. — A pair taken in Lat. 

 65 . Length of body 2*4 in. — 2^ lines. 



Body lurid-yellow, somewhat glossy, minutely and thickly punctured : 

 antennx dusky at the tip : prothorax with a minute black rhomboidal 

 spot in the disk, which is marked with a punctiform impression ; anteriorly 

 it has a transverse series of punctures larger than those of the rest of its 

 surface : elytra most numerously and minutely punctured : the suture and 

 four longitudinal stripes not reaching the apex, nor the first and third the 

 base, all black ; the fourth, or outermost, is distant from the margin and 

 interrupted : the alitrunk and abdomen are black. In the female, which is 

 less glossy, the external stripe is continuous, and only the second reaches 

 the base ; and in the male the prothorax is more conspicuously punctured, 

 and the anterior series of punctures is wanting. 



[67.] 95. Hvdroporus Parallelus, Say. — One specimen only taken. 

 [Previously described as //. Catascopium Say, and subsequently as II. 

 Interruptus Say : For descriptions vide Say's Ent. Books, ii., 98, 516.560. 

 Taken in Canada.] 



96. Hvdroporus L/evir, Kirby. — Length of body 2 lines. One speci- 

 men only taken.
