of both being the same), the species will probably be recognized in 
future under that title; and I have adopted it accordingly. 
§ IV. Prothorax seriebus dorsalibus e punctis septem vel octo 
composites. 
544, Philonthus punctipennis, n. sp. 
P. piceo-niger, capite subquadrato-ovato, elytris pubescentibus cre- 
berrime et fortiter punctatis, sutura vix dilutiore, antennarum basi 
pedibusque rufo-ferrugineis. 
Mas, tarsis anticis fortiter dilatatis. 
Long. corp. lin. 4-44. 
P. piceous-black. Head and prothorax highly polished, and nearly 
glabrous ; the former subquadrate-ovate, and with some very deep 
punctures on either side behind the eyes ; the latter with a longi- 
tudinal series of seven or eight punctures down either side of its 
disk, and with a few scattered ones between them and the edges. 
Elytra densely pubescent, very closely and rather coarsely punc- 
tured, and with the suture sometimes a little diluted in colouring. 
Antenne fusco-ferruginous; their base, the palpi, and the legs, 
more or less brightly rufo-ferruginous. 
Male, with the two front tarsi considerably dilated. 
Five specimens of the large and distinet Philonthus described above 
were discovered by Mr. Bewicke, in the river-bed at S'* Cruz (in the 
east of Madeira proper), during March 1856. The example in the 
British Museum was presented by its captor. 
§ V. Prothorax (et caput) sat crebre punctatus, lined media longitudi- 
nahi levi: palporum articulus ultimus magis acuminatus. 
545. Philonthus filiformis. 
Philonthus filiformis, Woll., Ins. Mad. 585 (1854). 
Inhabits Madeira proper, occurring in damp spots of intermediate 
altitudes. Rare. It is closely related to the P. procerulus of more 
northern latitudes, of which perhaps it may be but a geographical 
state. At any rate, Dr. Kraatz, to whom I sent it for inspection, 
returned it with the remark, “a procerulo antennis validioribus dif- 
ferre videtur.”’
