Habitat ins. Maderse Portusque Sancti, in stercore bovine, ubique vulgaris. 



P. black. Head and prothorax highly polished (generally with a slightly seneous tinge), and nearly 

 glabrous ; the former ovate ; the latter a little narrowed anteriorly, and with a longitudinal series 

 of five punctures down cither side of its disk, and with a few scattered ones between them and 

 the edges. Elytra closely and rather finely punctulated, and densely pubescent ; each of them 

 ornamented with a bright sanguineous patch (sometimes obscured, but rarely obsolete) between 

 its centre and inner apical angle. Antenna and leffs more or less obscurely picescent. 

 Male, with the two front tarsi slightly dilated. 



The five pimctures of whicli each of the dorsal prothoracic series is composed 

 will at once distinguish the present insect and the folio wirg one from the other 

 PMlonthi here described; whUst the P. hipustulatits may be immediately known 

 by the bright sanguineous patch (rarely obsolete) towards the inner apical angle of 

 each of its elytra. It is common in Madeira and Porto Santo, from the level of 

 the shore to the mountain- su m m i ts, — or at any rate to the highest elevations 

 accessible to cattle, in the dung of which it occurs. During July of 1850 it was 

 abundant in the upland district of the Fanal ; and on the grassy slopes to the 

 east of Funchal I have observed it in profusion. It is found throughout the whole 

 of Eui'ope and the north of Africa, and is recorded from Asia Minor and Syria.
