190 MADEIRAN: COLEOPTERA. 
the former ovate ; the latter slightly picescent, with a longitudinal 
series of five punctures down either side of its disk, and with a 
few scattered ones between them and the edges. Elytra a little 
convex, pubescent, and rather distinctly punctulated. Antenne 
brownish-piceous ; their base, and the legs, diluted-testaceous,— 
the tibie and tarsi being more infuscated than the femora. 
Detected by myself, during the summer of 1855, in the dung of 
cattle (at low elevations), both in Madeira and Porto Santo. In the 
former island it was tolerably common near Funchal,—at the Gor- 
gulho, and the Praya Formoza; but in the latter I only obtained a 
single specimen. I have lately transmitted it to Berlin, for the in- 
spection of Dr. Kraatz (who has just completed his Monograph, in 
the Insecten Deutschlands, of the German Philonthi); and it is 
regarded by him as new.

P. black. Head and prothorax highly polished, and nearly glabrous ; 
the former rather large, and rotundate-quadrate,—being a good 
deal truncated behind; the latter with a longitudinal series of five 
punctures down either side of its disk, and with a few scattered 
ones between them and the edges. Hlytra quadrate, very pubes- 
cent, rather distinctly punctulated, and with their entire margins 
(except the basal one) bright-testaceous. Antenne rather short, 
robust, and pale brownish-ferruginous. Legs infuscated-testa- 
ecous. 




Of the common European P. discoideus I captured a single ex- 
ample, during the autumn of 1855, in a garden at Funchal. It is 
stated by Erichson to be a species of very wide geographical range.
