382 MR. G. R. CROTCH ON AZOREAN COLEOPTERA. [Mar. 28, 



172. H. LONGULA, Heer. 



Found, but very rarely, in the bed of a stream in Fayal. 



173. H. ATRiciLLA, Er. (flavipes. Thorns.). 



One specimen, from the coast at Ponte Delgada, S. Miguel. Tliis 

 species is new to the Atlantic fauna, and is interesting as showing 

 the wide distribution of these sea-weed infesting forms. 



174. H. PUTRESCENS, "VVoll. ? 



From Flores, under refuse. These are not in good condition ; 

 but appear to be near Mr. Wollaston's species. They will almost 

 certainly prove to be European also. 



175. H., sp.? ' 

 S. Miguel, under refuse. 



17t). H. coriaria, Kraatz? 



Three specimens, from S. Miguel. This and tlie preceding are 

 both females, and I am unable to identify them satisfactorily. Both, 

 however, appear to be European forms. 



177. H. NIGRA, Kraatz? 



This little species, which is not rare in dung, appears to agree with 

 the Canarian specimens referred to H. nigra, Kr., by Mr. Wollaston. 



178. H. ATRAMENTARIA, Gyll. 



Not rare in dung in S. Miguel, Fayal, and Flores, and probably 

 universal. 



179. 11. MELANARIA, Sahib. 



Abundant in dung in Terceira, Fayal, and S. Miguel. 



180. Xenomma melanocephala, n. sp. 



Two specimens were obtained from the rubbish in S. Miguel. It 

 is allied to the other Atlantic species, but is abundantly distinct from 

 them. 



181. Habrocerus capillaricornis, Grav. 



Two specimens, from vegetable refuse in S. Miguel. This would 

 appear to be a remnant of the old laurel-fauiia. 



182. Conosomus sericel'S, Latr. (pubescens, Payk.). 



A single mutilated specim.cn, from a Euphorbia-stem in Flores. 



183. Creophilus maxillosus, L. 



Local, but occasionally abundant in S. Miguel and P'ayal. M. 

 Drouet records it also from Flores and Graciosa.
