Habitat Maderam, tempore sestivo, bine inde \Tilgaris, a 2500' s. m. usque ad caciimina montium 

 ascendens : ad Lombo das Vacas die solstitiali a.d. 1850 primus inveni, et plurima specimina e 

 floribus Cineraria aurita {■= Senecionis Maderensis, De Candolle) ad Cruzinhas crescentis mense 

 Jubo ejusdem anni cepi; aba etiam in summo ipso monte (6100' s. m.) Pico Ruivo dicto, flores 

 EriccE cinerete circumvolantia, Augusto ineunte deprebensi. 



P. elongate-ovate (being rather dilated behind and acuminated anteriorly) ; pubescent and shining ; 

 seneousj with a more or less brilliantly greenish or coppery splendour. Head and prothorax brightly 

 polished, and sparingly punctured : the forrner roundish, convex behind, and with two rather deep 



by the Eev. W. J. Armitage in Teneriffe : — so that it is far from improbable that Pecteropus may em- 

 body a type of form which obtains, more or less, throughout the whole of the islands of this portion of 

 the Atlantic. The following short description may serve to characterize the Canarian representative : — 



Pecteropus pelluoidus, Woll. 



P. antice subacuminatus, pubescens nitidus feuescenti-mger, capite protboraceque parce pvmetatis, illo 

 subrotundato latiusculo, hoc parvo ad angidos posticos pallido-pellucido, elytris leviter subpunctato- 

 rugulosis, antennarum tarsorumque basi subinfuscata. 



Long. corp. Un. 1§. 



Habitat in insula Tenerifia Canariensi, a Eev''° Dom. Armitage communieatus. 



P. elongate-ovate (being dilated behind, and rather acuminated anteriorly) ; piibescent and shining ; black 

 with a greenish-brassy tinge. Head and protJim-ax rather brightly polished, and very sparingly and 

 minutely punctured : the former roimdish, nather convex behind, but with very slight indications of 

 frontal impressions ; vrith the ei/es prominent : the latter small, and widest about the middle ; and 

 with the hinder angles pale whitish-testaceous and pellucid. Elytra very lightly rugulose and sub- 

 punctate. AntenncB at base, together with the extreme apices of the tibia and the bases of the tarsi, 

 infuscate. 



A most elegant little species ; approaching more nearly, in its general outline and sculpture, to the 

 P. Maderensis than to either of the other Madeiran members of the group : nevertheless, its comparatively 

 dark siu-face (which is black, with a greenish-brassy tinge), in conjunction with the pale and curiously 

 transparent portion of its margin at either posterior angle, will at once abundantly characterize it.
