INSECTA MADERENSIA. 581 



and nearly glabrous ; the former somewhat roundish-quadrate, with some large and coarse punc- 

 tures on either side behind the eyes, and with four others (arranged transversely) between them ; 

 the latter with a longitudinal series of four punctures on either side of its disk, and with a few- 

 scattered ones between them and the edges (which are a little sinuated), — where also it is most 

 obsoletely impressed. Elytra rather more seueous than the head and prothorax, and usually 

 with a more perceptibly greenish tinge; closely punctulated, and densely pubescent. Leffs 

 sometimes (especially the tibife and tarsi) slightly piceous. 

 Male, with the fourth segment of the abdomen beneath deeply and triangularly notched ; and with 

 the two front tarsi greatly dilated. 



An insect of very wide geographical range, occurring in all parts of Europe, and 

 beinff recorded from the confines of Asia and from South America. It appears 

 to be rather scarce in Madeh-a, though diffused over the island at all elevations. 

 I have taken it, sparingly, in the vicinity of Funchal ; and during July of 1850, 

 in the upland region of the Fanal. It may be at once known from the other 

 Fhilonthi with which we have here to do by its large size and more seneous sur- 

 face, by its somewhat more quadi-ate head, and by the subsinuated edges (and the 

 oblique, though almost obsolete, impression on either side) of its prothorax. The 

 deeply notched fourth segment moreover of the abdomen of the males will addi- 

 tionally serve to distinguish that particular sex.

P. deep black. Head and prothorax highly polished, and nearly glabrous ; the former roundish, and 

 with the same character of punctuation as in the last species (and which obtains throughout all 

 the following ones except the P.Jiliformis), and with the 2'('lpi either piceous or dull ferruginous ; 

 the latter with a longitudinal series of four punctures down either side of its disk, and with 

 about five scattered ones between them and the edges (which are perhaps a little straighter than 

 in any of the other species here described). Elytra generally with a distinct seneous tinge; 

 closely and finely punctulated, and densely pubescent. Antenna rather long, and more or less 

 obscurely picescent towards their base. Legs piceo-testaceous, — being pale, but unequally 

 darkened in parts. 

 Male, with the two front tarsi greatly dilated.
