wMcli stud its (densely alutaceous) head considerably smaller and 

 more remote — indeed hut just traceable. Its abdomen (througli being 

 more sparingly punctured) is a little less opake ; and its legs are 

 usually less infuscated, or of a slightly clearer testaceous hue. I 

 believe it to be identical with the European H.fragilis ; nevertheless, 

 as it is very possible to be mistaken in species thus small and obscure, 

 I have cited it as such with a mark of doubt. It occurs in precisely 

 the same kind of places as the H. longula. I have taken it in the 

 Barranco Santo (near S'" Cruz) in TenerifFe, near San Sebastian of 

 Gomera (in which island it was found Likewise by Dr. Crotch), and 



in Palma. 



812. Homalota cursitans, n. sp. 



H. angustulo-linearis, nigra elytris fuscescentibus, nitida, parce pu- 

 bescens, densissime subtilissimeque alutacea punctuhsque minutis 

 irrorata ; capite subrotundato ; prothorace transverso-subquadrato, 

 anguhs posticis sat argute determinatis ; abdomine grosse sed parce 

 asperato-punctato ; antennis pcdibusque brevibiis, crassis, illis ad 

 basin vix dilutioribus, his infuscato-testaceis. — Long. corp. lin. 1^. 



Habitat Lanzarotam, ultra oppidum Haria parce capta. 



This little species I have observed hitherto only in the north of 

 Lanzarote — chiefly beneath the refuse around the roots of the old 

 Euphorbias on the rocky declivities of the " Eisco." Its narrow, 

 linear outline and densely alutaceous (though, at the same time, 

 rather shining) surface, which is studded with smaU additional punc- 

 tules, combined with the tolerably well-defined hinder angles of its 

 prothorax, its brownish elytra, very thick antennae, and infuscated- 

 testaceous legs, are some of its principal features. 



813. Homalota subsericea, n. sp. 



H. prsecedenti simiKs, sed minor, subangustior, punctulis superadditis 

 (oculo fortLssime armato) etiam minoribus,valde indistinctis ; capite 

 vix magis quadrato ; prothorace vix breviore, angulis posticis rotun- 

 datis, fere obsoletis ; elytris singulis in disco obsolete impressis ; 

 antennis vix brevioribus minusque incrassatis. — Long. corp. lin. 1. 



Habitat Lanzarotam, in iisdem locis ac pra3cedens. 



This Homalota is very closely aUied to the last one, and is found 

 (so far as I have observed hitherto) in the same district — namely, the 

 north of Lanzarote. It diff'ers from it in being smaller and rather 

 narrower, and in the punctulcs of its (densely alutaceous) surface 

 being still more obscure and minute, in its elytra being obsoletely 

 impressed on either disc, in its antenna3 being appreciably shorter and 

 less incrassated, and (above all) in the hinder angles of its prothorax 

 being more rounded off (or less defined) . I am far from satisfied that
