Habitat in locis inferioribus Maderse, prjesertim circa urbem Funchalensem, tempore vernali, rarior : 

 ad Praya Formoza mense Martio a.d. 1848 plurima specimiua e floribus collegi. 



P. elongate- subovate (being however rather broader anteriorly, and therefore a little more parallel, 

 than the P. Maderensis) ; more thickly pubescent, and rather less shining, than the last species ; 

 aeneous, with a coppery (rarely with a greenish) additional tinge. Head and prothorax thickly 

 and coarsely granulated : the former roundish, less convex than in the last species, and \v\i\\ 

 scarcely any indications of frontal impressions ; with the eyes prominent : the latter widest about 

 the middle, usually a trifle larger than that of the P. Maderensis, and with the anterior angles 

 perhaps a little more rounded. Elytra coarsely rugulose, and subpunctate ; very slightly 

 expanded behind. Antenna at base, and the legs rufo-testaceous ; the /onwe;- rather short, and 

 scarcely longer in the males than in the females ; the latter with their femora (in both sexes) 

 more or less infuscated. 



A species confined, apparently, to low altitudes, occurring during the spring 

 months in the immediate vicinity of Funchal. It appears to vary but little either 

 in sculptiu'e or coloiu', — the former being universally coarse, and represented on 

 the head and prothorax by closely-set tubercles ; whilst the latter is seldom 

 brilliant, being generally of a dull coppery-, or almost brownish-brassy hue 

 (having only a tinge of green), and but very slightly shining. The males of all 

 the Fecteropi here descril^ed differ so essentially in the structure of the second 

 joint of then- fore-feet, that there is but little fear of confounding them (even when 

 their other distinctive characters are aberrant) inter se. Nor indeed is there any 

 difficulty as regards the opposite sex, except now and then, in rare cases, when (as 

 lately stated) the females of the present insect might not always be at once recog- 

 nised from those of the last one. A more careful examination, however, will never 

 fail to separate the two, since the smaller size and broader outline (that is to say, 

 less expanded posteriorly, and therefore less narrowed in front) of the P. rugosiis, 

 in conjimction with its flatter head (which has scarcely any indications of the 

 longitudinal impressions which are so conspicuous in the P. lladerensis), and its 

 usually rather shorter antennge, will aU tend (apart from its more obscure, coppery 

 and roughened sm*face) to remove it, even at first sight, from every variety of the 

 P. Maderensis. It seems to be somewhat scarce, or at any rate local ; occurring
