ADEPHAGA. 17 



^deagus obtusely rounded at the 

 apex with a subrectangular projec- 

 tion near the apical third of its 



convex edge H. Wehnckei, Gerh, 



b*. Elytral interstices of female with- 

 out punctuation. Left side-lobe of 

 pedeagus with a large triangular 

 tooth near the middle of its concave 

 edge, ^deagus narrowly pointed, 

 its convex edge a little subangularly 



dilated near the middle . . . H, immaculatus, Gerh. 

 2. Head black or blackish. Thox'acic im- 

 pression falcate, reaching at least to the 

 half length of the thorax. Metaster- 

 num with two straight, divergent 

 keels H, LiNEATOCOLLis, J/ars/i. 



The above characters seem to be satisfactory, but it should be 

 remembered that Bedel, who is usuall}- a very accurate observer, 

 remai'ks (Faune. Col.du Bassin de la Seine, i. 222) on the occurrence of 

 every shade of transition in colour, form and punctuation in a large 

 series of the H. rujicollis group, and he also alludes to the dimorphic 

 character of the sculpture of the elytra in the females, some having the 

 elytra smooth, whereas in some it is more or less ''alutaceous" ; 

 Mr. Edwards says that he has found no tendency towards dimorphism 

 in the species, and rightly objects to the term " alutacees " by which, 

 however, Bedel evidently refers to the irrorate punctuation. 



H. pallens, Fowler (Edwards, Ent. Mo. Mag. xlvii. (2 ser. xxii.) 

 1911, 5). H. confinis, S'teph., var. pallens. Fowler, Brit. Col. i. 153 

 The ground colour in this species is the same as in H. obliqims, 

 from which it difFei's in the possession of a longitudinal impression, 

 bounded outwardly by a distinct ridge on the base of the thorax, 

 opposite the fourth row of elytral punctures. The black markings on 

 the elytra somewhat resemble those of H. obliquus at first sight, but 

 the four inner lines are not interrupted behind the middle as in that 

 species ; the suture and the base of the elytra are narrowly black. It 

 is paler and narrower than //. confinis, with the thorax longer in 

 proportion to its width and the elytral pattern diflerent. L. 3j- 

 3J mm. 



Loch Leven (Power) : Mr. McNab appears to have taken the species, 

 probably at Loch Leven, and there are examples in Mr. Waterhouse's 

 collection, pi-obably from Mr. Bold, 



H. fulvicollis, Er., KUf. Mk. Brand, 37, 186 (Edwards, I.e. p. 7). 

 Similar to H. ruficollis, but scai'cely so wide at the shoulders and more 

 gradually narrowed behind, the ground colour dark red-yellow, the 

 black markings on the elytra more pronounced, and the punctuation 

 of the elytra in the females confined to the apex and the distal
