9. A. congener, Payk., GylL, Steph. A. confinis, Steph., not GylL 

 Long. 7j— 8 ; larg. 4^ — 4j. Suffolk, Norfolk ; rare near London : 

 but little is known of the localities or habits of this insect. 



(A. confinis, GylL, Sahib. Long. 8j — 9j ; larg. 4| — 5. Head and 

 thorax black, without the narrow ferruginous border of A. congener; 

 elytra slightly elongate, dark brown, with lateral borders cloudily but 

 broadly testaceous; with 3 longitudinal lines of punctures; smooth, 

 not reticulated as in A. congener. North of Europe, Sweden, 



Finland.) 



(A. nigricollis, Zoubkoff. Long. 9; larg. 4f. Head black, labrum 

 and two spots in anterior red ; thorax black, lateral margins slightly 

 ferruginous ; elytra slightly elongated behind, varying in colour from 

 pitchy brown to bright red-brown ; with two spots, hardly, sometimes 

 not at all, visible, one on external margin, the other at apex.) 



10. A. femoralis, Payk., GylL, Steph., Sturm. A. assimilis, Sturm, 

 Aube. Near London ; Cambridge ; generally distributed. 



11. A. uliginosus, Payk., GylL, Sturm. Long. 7 ; larg. 4. South- 

 end ; Windsor ; rare near Edinburgh ; Aberdeenshire. Rare. 

 A. dispar, Bold (Zool. 1849, xxiv.), must be referred to this species, 

 as I have ascertained by comparison of a fine series which Mr. Bold 

 obligingly allowed me to examine. 



(A. fuscipennis, Payk. Long. 9^- — 10; larg. 5j — 5f. Fuscous; 

 thorax dark brown, irregularly punctuated with a few more deeply im- 

 pressed punctures on anterior margin ; lateral borders broadly ferru- 

 ginous, anterior narrowly; elytra oval, considerably dilated in front 

 of the middle ; colour and broad lateral margins in thorax, punctua- 

 tion more fine. North of Europe.) 



(A. Reichii, Aube. Long. 7j; larg. 4^-. Closely allied to A. uli- 

 ginosus : differs in form, which is more convex, and by the greater 

 dilatation of elytra a little in front of the middle : it appears to cor- 

 respond in colour and punctuation entirely with A. uliginosus.) 



12. A. abbreviatus, Fab., GylL, Steph., Aube. A common 

 species in the Fen districts ; Windsor ; Mr. Newman has taken it at 

 Leominster. 



13. A. maculatus, Linn., Fab., Steph. Frequents especially brooks 

 and running water throughout the kingdom : dark varieties are occa- 

 sionally met with. 



14. A. vitreus, Payk. A. didymus, Ollv., Aube. Generally dis- 

 tributed, but not abundant. 



15. A. bipunctatus, Fab., GylL, Aube. A. nebulosus, Forst., Sleph. 

 Very common.
