NEW GENERA OF EUROPEAN P HYC 110 DID Ai. 

 BY THE REV. A. E. EATON, M.A., F.E.S. 



Species of PstjcliocUdce being very numerous, it is desirable that 

 they should be collected into smaller genera than hitherto current. I 

 therefore j)ro[)ose a generical redistribution of Fericoma and Fsychoda 

 of authors, dealing only with European species. 



Adopting the neurology of Professors Comstock and Needham, 

 instead of that previously employed by me \cf. Ent. Mo. Mag., ser. 2, 

 vol. iv, p. 7, woodcut (1893)], the numbered wing-veins are termed 

 respectively : — 0, Costa ; 1, 8ubcosta for Mediastinal ; 2, Radius for 

 ISubcosta ; 3, 3' & 4, branches of the liadial Sector or Radial fork and 

 Sector for Radius and Cubitus; 5, Median vein for Prajbrachial ; 

 G & G', Cubitus, Cubital fork, or 1st and 2nd Cubital veins for Po- 

 brachial ; 7, First Anal for Postical vein; 8, Second Anal for the 

 Anal vein ; 9, Third Anal for Axillar vein. 



Although no new genus is at present proposed in the Sub-Family 

 PklebotomincB, th.G genera may advantageously be passed under review, 

 by way of introduction, without treating of them exhaustively. They 

 may be classed in two series. 



1st Seeies, NEMOPALPUS, Macquart, and PHLEBOTOMUS, Ron- 

 DANi. — Antennse IG-jointed, with short 2-jointecl scape, and long (the Ist joint very 

 long) filiform joints in the flagellum ; proboscis prolonged, and palpi elongate, with 

 a flexible terminal joint. Alula rudimentary, erect, obtuse; anterior basal cell 

 elongate, with only a sliallow sinus in front before its apex ; radial sector 3-branched, 

 constituting the Sectional fork and a simple branch ; the stem of this fork in Nemo- 

 palpus is extremely long, extending nearly to the middle of the anterior basal cell, 

 the tines of the fork being very short ; but in Phlebotomus the stem is shorter than 

 the depth of the fork, and is confluent witli the simple branch far beyond the cell. 

 Third anal vein in Phlebotomus wanting or hardly distinguishable from the Anal 

 furrow ; in Nemopalpus short, descending to the wing-margin not far from the 

 Anal cross-vein. The figures of Nemopalpus by Macquart (1838) and Loew, fig. 15 

 (1845), like those of Phlebotomus by Rondani (18i3) and Loew (1844), do not 

 accurately correspond in wing-neuration with my microscopical preparations, owing 

 probably to their having omitted to denude their specimens sufficiently of hair. 

 Wings narrower and more pointed than in flies of the other series. 



Nemopalpus has genitalia similar in character to those of Phlebotomus ; but 

 through paucity of material I have only been able to view them in sitil witliout 

 denuding them and in the dry fly. My preparations of Phlebotomus at this date 

 are also from the dry fly only, and therefore I will say nothing about the innermost 

 parts on this occasion. 



The basis upon which the inferior pair of genital appendages (hereafter ab- 

 breviated to inf. app.) of the i lly are borne, is in reality the anal segment, which 

 dorsally is abbreviated (sometimes to a hair-like loop) to make room for the opposed
