still (as I have already shown) the name of Glceosoma velox has the 

 priority*.

Habitat Maderenses (Mad.), sub quisquiliis in inferioribus interme- 

 diisque captus. 



A very minute insect which has been taken sparingly in Madeira 

 proper, beneath vegetable refuse at low and intermediate altitudes. 

 I met with it near Funchal ; and it was captured subsequently by 

 the late Mr. Bewicke at the Praia Formosa, and at S. Antonio da 

 Serra.

Habitat Maderenses (Mad., Des.) et Canarienses (Fuert., Can., Ten., 

 Gom.), sub quisquiliis necnon in herbidis humidiusculis vulgaris. 



There are few insects more widely spread over these Atlantic 

 islands than the common European S. lateralis. Indeed I think it 

 far from improbable that it will be found ultimately to be universal, 



* Happily it is not often that we are compelled to call attention to such a 

 string of evasions as that which M. Duval allowed himself to be led into con- 

 cerning my Glaosoma vclox (which he misquotes as G-locosoma). For, in the 

 first place, he did not hesitate to identify the genus positively with his Moronillus, 

 whilst my diagnosis and figure both showed it to be totally distinct. Then, he 

 referred the species also to his ruficollis with which, even had the, genera coincided, 

 it could not be made to agree. And lastly, he had the duplicity to suppress 

 both my genus and species, in favour of his own, when he was perfectly well 

 aware that it had the priority in publication by at least several months, and 

 that, too, whilst his notice of Moronillus was short and incomplete, and mine of 

 Gfaosoma was comparatively full and accompanied by an elaborate figure, both 

 of the insect and its oral organs !
