1867.] MR. G. R. CROTCH ON AZOREAN COLEOPTERA. 383 



184. Staphylinus hesperus, n. sp. 



Abundant under stones near Terceira. It appears to be allied to 

 a Cape species. 



185. OcYPUS OLENS, Miill. 



Common throughout the group, as it is also in the Canaries. Its 

 absence from Madeira is a very curious and important fact. 



186. Philonthus ^eneus, Rossi. 



Rare in S. Miguel and Fayal, and probably a mere introduction. 



187. P. soRDiDUS, Grav. 



In vegetable refuse and dung in S. Miguel and Fayal. 



188. P. UMBRATiLis, Grav. 



Tolerably common in S. Miguel and Fayal. M. Drouet records 

 P. ventralis; but I am inclined to imagine he had the present species 

 in view, notwithstanding the discrepancy in the thoracic punctures. 



189. P. scYBALARius, Nordm. 



Two specimens taken in Fayal are referable to this species. 



190. P. NiGRiTULUs, Grav. 



Very abundant in damp places in S. Miguel, Terceira, Flores, and 

 Fayal. 



191. P. PROXIMUS, Woll. 



A single specimen, from a mountain-stream in Fayal. This species 

 was supposed to be peculiar to Madeira, where it is very rare. 



192. Xantholinus glabratus, Grav. 



According to M. Drouet this was found by M. Hartung under 

 stones in Graciosa. If this indication be correct, it is a species new 

 to the Atlantic fauna. Possibly he may allude to the analogously 

 coloured X. marginalis, Woll., hitherto found only in the Canaries. 



193. X. punctulatus, Payk. 

 Not rare in S. Miguel and Terceira. 



194. X. hesperius, Er. 



In San Miguel and Fayal under refuse. 



195. X. linearis, Oliv. 



With the preceding, and also in Terceira. 



196. Leptacinus pusillus, Ste^jh. (linearis, Grav.). 



Under refuse at Ponte Delgada, S. Miguel. Gravenhorst's name 

 is inapplicable, having been adopted erroneously from Olivier.
