18G7.] MR. G. R. CROTCH ON AZOREAN COLEOPIERA. 3G9 



21. S. (ACUPALPUS) LURIDUS, Dej. 



On the coast in S. Miguel and Terceiia. This is new to the At- 

 lantic fauna ; and it is very curious that the pale form should occur, 

 whereas the dark form of the preceding is present. 



22. Bradycellus distinctus, Dej. 



One specimen only, from the Lagoa das Furnas, S. Miguel. It is 

 new to the Atlantic fauna. Compared with English examples, the 

 elytra are more ventricose and have the interstices perceptibly flatter. 

 If further material should show that it is really distinct, I shall pro- 

 pose the name " azoricus" for it. 



23. Trechichus fimicola, Woll. 



One specimen, from Fayal. This does not quite agree with Ma- 

 deiran types in the British Museum, being distinctly paler, and with 

 more faintly striate elytra. Further material can alone decide 

 whether these characters are permanent or not. 



24. TaCHYS 4-SIGNATUS, DuftS. (CURVIMANUS, Woll.). 



Not rare in S, Miguel, Terceira, and Fayal. Those from Terceira 

 are paler and more faintly striate. It is common in South Europe, 

 Madeira, and the Canaries ; at least I am unable to distinguish be- 

 tween specimens from Spain and the hitter locality. 



25. Bembidium (Ocys) rufescens, Fabr. (dubium, Woll.). 



S. Miguel, Fayal, and Flores ; also in Santa Maria (Drouet). A 

 careful comparison of it with English specimens and with Mr. Wol- 

 laston's type in the British Museum has convinced me that they 

 should be referred to one species. 



26. B. (Lopha) schmidtu, Woll. 



This insect, which assumes a different form in South Europe, 

 Madeira, and the Canaries, here appears to approximate most closely 

 to the Madeiran race ; the coloration, however, is darker, the testa- 

 ceous patches being less developed. It is not common in S. Miguel 

 and Fayal. 



27. B. (Leia) HESPERUS, n. sp. 



Two examples only, under marine rejectamenta at Praya in Ter- 

 ceira. It is most nearly allied to B. Icetum, BruUc. 



28. Hydroporus planus, Fabr. 



Not rare in ponds in Terceira, Fayal, and Flores. It is darker 

 than the ordinary English form, but I am unable to detect any tan- 

 gible differences. 



29. CoLYMBETES (Rhantus) pulverosus, Sturm. 



New to the Atlantic fauna, but is probably introduced ; atvl when 

 one reflects on the introduction of goldfish, it is easy to see that
