ADEPHAGA. 19 



Deal, on the road to Sandwich (Chitty) ; Isle of Sheppey (Walker) ; 

 Camber (Bedwell). 



This is the insect introduced by Mr. Chitty as II. bilineaius, Sturm 

 (Ent. Mo. Mag. xxxix. (2 Ser. xiv.) 1903, 144); it is, however, quite 

 distinct by its narrower form, its colour, and the more diffuse punctua- 

 tion of the elytra. It is allied to H. granularis, L., but differs entirely 

 in shape, in the punctuation of the elytra, and in the absence of the 

 two yellow lines on each elytron. 



Gerhardt (Deutsch Ent. Zeitsch., 1909, 423) has a note on this 

 species, which he still regards as a variety of 11. bilineatiis, but thinks 

 it may very probably turn out to be a distinct species; Bedel (Faune. 

 Col. du Bassin de la Seine, i. 262, note) says that II. bilineatiis is the 

 male of H. granula7-is ; this is evidently not the case ; H. hilineatus 

 appears to be confined to Central Europe and does not, probably, occur 

 in Britain, 



H. palustris, L.,var. tinctus, Clark. Ann. Mag.jSTat. Hist. x. 326. 

 I have before referred to this variety (Brit. Col. i. 182) ; the testaceous 

 spots are almost if not quite obsolete, and the whole insect is of a reddish 

 or fuscous colour ; it occurs in the New Forest, where it was taken by 

 Turner. Dr. Sharp (Dytiscidse, p. 813) says that he believes it to be 

 a variety of H. palustris, but it may possibly be H. incognitus, Sharp, 

 in which case the name 11. tinctus must stand, as it has seven years' 

 priority. Ganglbauer does not mention the vai-iety, but in the last 

 European catalogue it is given as a variety of Il.jonicus, Mill, which 

 can hardly be correct, as II. jonicus is a Mediterranean species ; it is 

 described by Ganglbauer as being 4 mm. in length (the size of large 

 specimens of //. ■palustris), and as distinguished from //. jxdustris by its 

 much more elongate and narrower form, the shining upper side in both 

 sexes, the much more strongly punctured elytra, the more strongly punc- 

 tured hind coxpe, the longer and more slender tarsi, and the very slightly 

 uneven claws of the anterior tarsi in the male. 



In vol. i. p. 183, II. celatus, Clark, is given as a synonym of II. 

 longiilus, Muls. ; Clark's name should stand, and it has priority assigned 

 to it in the European catalogue (1906) ; the species is variable, and we 

 ought, perhaps, to say U. celatus, Clark, and var. longulits, Muls. 



AGABITS, Leach. 



A. bipustulatus, L., Syst. Nat. x., ii. 1767, 667. As I have 

 before said (Brit. Col. i. 197), in the mountainous districts of England, 

 Wales or Scotland, the examples of this species become smaller, narrower, 

 moi-e oblong and depressed : the males become more shining, and one 

 form of the female much duller, so that the disparity of the sexes 

 appears much greater than in the type form : to these forms must be 

 referred the var. snoiodonius, Newman (Ent. Mag. i. 1832, 55), and the 

 var. soliei'i, Aube. 



In the European Catalogue of 1906, A. bijnistulattis and A. solieri 

 are treated as separate species, with the following synonyms :
