with a minute cinereous pubescence ; by the light (but not very 

 regular) subalutaceous sculpture of its head and prothorax, on which 

 there are only a few excessively small and remote punctures inter- 

 mixed ; and by its very closely punctulated elytra, which are rather 

 flattened on the disk, usually with very faint indications of longi- 

 tudinal costa), and beset with erect hairs. My Fuerteventuran 

 examples arc principally from the Rio Palmas. 



18. Attalus metallicus, n. sp. 



A. ameo-, viridi-ameo- vel cyaneo-niger, subglaber, nitidus, supra (pne- 

 sertim in elytrifl) sat profunde denseque punctatua ; elytrifl pilis fere 

 carentibus ; antennis ad basin tarsisque, necnon interdum etiam tibiis, 

 plus minus testaceo dilutioribus. 



Yar. j3. sintilis. Vix profundius densiusque punctatus, prothorace ad basin 

 subinsequali. [Ins. TenerifFa.]

The comparatively deeply punctured and almost glabrous surface of 

 this Attalus, in conjunction with its metallic hue, which is generally 

 greenish brassy, but occasionally almost cyaneous, will sufficiently 

 characterize it. It is rather common in Lanzarote, in the north of 

 which island it was taken by Mr. Gray and myself, during January 

 of 1858, from off the flowers of Euphorbias ; in which district I 

 again met with it early in March of the following year. I have also 

 a single specimen (the " var. (3 " indicated above) which I captured 

 in Teneriffe, thoxigh I cannot now recall the precise locality : it is 

 altogether a little more deeply and closely punctured, and has the 

 base of its pronotum a trifle raised and uneven ; but I do not per- 

 ceive anything about it to warrant the suspicion that it is specifically 

 distinct. 



19. Attalus cenescens, n. sp. 



A. ameo-niger, minute cinereo pubescens, nitidus ; capite prothoraceque 

 rotundato minute et plus minus dense punctulatis ; elytris dense punc- 

 tulato-subrugidosis, interdum obsoletissime subeostatis, pilis nigris 

 suberectis plus minus obsitis ; antennis pedibusque nigris, illis ad basin 

 tarsisque (rarius tibiis) vix dilutioribus. 



Var. /3. puncticottis. Colore paulo obscuriore, prothorace densius pimctato, 

 elytris ad basin vix minus pilosis. [Ins. Palma et Teneriffa.] 



Var. y. umbrimis. Colore obscuriore, interdum etiam subnigrescente. [Ins. 

 Canaria Grandis]
