APPENDIX. 



Metophthalmus ferrugineus, n. sp. 



M. praecedenti fere similis, sed oblongo-ovatus, postice paulo con- 

 vexior, necnon omnino ferrugineus, elytris minus grosse seriatim 

 punctatis. Long. corp. lin. |. 



Habitat in ins. Hierro, a DD. Crotch nuper lectus. 



Captured abundantly by the Messrs. Crotch in Hierro, the most 

 western island of the Canarian Group. It is a little more ovate 

 (and convex posteriorly) than the last species, and entirely of a 

 ferruginous hue ; and its elytra are less coarsely seriate -punctate. 

 It seems likewise, on the average, to be a trifle smaller than the 

 M. a&peratus. I believe that the Messrs. Crotch's examples were ob- 

 tained by sifting dead leaves, and other rubbish, in the wooded district 

 ofElGolfo. 



Metophthalmus encaustus, n. sp. 



M. minor, brevior, regulariter ovatus, vel omnino rufo-ferrugineus 

 vel in elytris obscurior ; elytris ad humeros paulo magis porrectis, 

 acutioribus, et valde profunde seriatim puuctatis (punctis maxi- 

 mis). Long. corp. lin. &. 



Habitat in intermediis sylvaticis Teneriffse et Gomerae (prsesertim 

 hujus), inter lignum aridum antiquum neenon sub foliis aridis 

 dejectis occurrens. 



Of this little Metophthalmus I took a single example in TeneriiFe 

 (in the laurel-wood at Las Mercedes), during June 1858, but as I 

 unfortunately lost it I had no opportunity of drawing out a diagnosis 

 and including it in my Canarian Catalogue. It has however been 

 captured lately by the Messrs. Crotch (sparingly in Teneriife, but 

 abundantly in Gomera), by sifting fallen leaves a most profitable 

 method of collecting, which I did not adopt. 



The M. encaustus is an exceedingly well-marked species; for 

 although it may be said to be decidedly variable in hue (being some- 

 times entirely rufo-ferruginous, and at others with the head and 

 prothorax of that colour whilst the elytra are considerably darker), 

 nevertheless its comparatively ovate outline and the perfectly enor- 

 mous punctures of its elytra (which have their shoulders more or 

 less porrected, or acute) will easily distinguish it from the others 

 here enumerated. It is smaller than either of the preceding species, 

 but larger than the following ones. 



Metophthalmus sculpturatus.
