182 I August, 



P.fuscicorne, Erichs. (Nat. lus. Deutsclil. 111,37). — lu moss and 

 at roots of plants at sides of streams, and also in marshes. Widely 

 distributed from Aberlady to the south coast, Isle of Man, Ii-elaud, &c. 



P. myrmecophilum, Mots. (Bull. Mosc, 1845, 518) = formice- 

 tornm, Ivr. Eepresented in the Matthews collection by lasvigatum, 

 myrmecophUum, nitidum, and pusillum, almost all Mattliews's own 

 specimens being leevigatum. The type of the var. hraatzi in the British 

 collection is a rather small myrmecophilum with the outer basal thoracic 

 fovea} much deeper than the middle pair. — One specimen ex coll. 

 Bates (Joy), two specimens, near Leicester (lal)elled " kraatzi " by 

 Matthews) (Fowler). Appears to be rare. In Matthews's European 

 collection are two bad specimens under hraatzi: one appears to be 

 myrmecophilum, the other intermedi^i,m. 



P. pusillum, Gyll. (Ins. Suec. I, 189, 1808) = apicale, Erichs. — 

 The very numerous specimens of this common and widely distributed 

 species in the Matthews collection have not been examined. It occurs 

 in dead leaves, moss, &c., in Britain, Ireland, and the Isles of Wight, 

 Man, Lundy, Scilly, &c. 



P. hrisouti, Matth. (Trichopt., 82) = nitidum, Bris, (Cat. G-ren., 

 43, 1863), nee Heer. Represented in the Matthews collection by 

 a small specimen with paler antennae than usual, from C. Brisout 

 himself (see footnote 5). A second specimen is most probably 

 pusillum, Gryll., the third and last is nitidum, Heer. — In moss on 

 banks of ponds and streams, in flood refuse, debris of reeds and 

 rushes, &c. Banks of Thames, Walton (Champion) ; banks of River 

 Eden and ponds at Gi-reat Salkeld (Britten) ; Bradfield (Joy) ; Duu- 

 chediock, near Exeter (de la Garde) . 



P. nitidum, Heer (En. Helv., 377, 1841) = lawiyatum, Matth., 

 nee Erichs. — It has not been considered necessary to examine the 

 numeroiis specimens of this common species in the Matthews collection. 

 Like pusillum, G-yll., it is widely distributed and very common, often 

 occurring with it. The variations in size, colour, and pubescence have 

 given rise to several so-called species, among which we may rank 

 P. Isevigatum of Matthews {nee Gillm.), which is represented in his 

 collection by nitidum, Heer, with pale elytra, labelled " pusiUumva.r.,'" 

 by Brisout; a,notlier nitidum from Aube, and several pusillum, Gryll., 

 from Jekel. The P. salinum. Mots., of the Matthews collection must 

 be referred to this species, as also must the type of P. attenuAitum, 

 Matth., which is an example of the pale form. 



We desire to render our best tlianks to the following gentlemen
