from that so named by Walker, Haliday, and Schiner, the anal 
cell being closed in the former and open in the latter. He there- 
fore proposes a new name for Ptiolina of recent authors, and 
gives the following table of the characters of this and the allied 
genera t — 
I. Joint 3 of antennse round, oval, or conical ; seta terminal. 
a. Anal cell open Leptis. (Type L. scolopuced, Linn.) 
h. Anal cell closed. 
a. Seta hair-like Chrysopila. (Type C. atrata, Fab.) 
/3. Seta sty liform Ptiolina. (Type P. oftscwra. Fall.) 
II. J oint 3 of antennce reniform ; seta apparently dorsal. 
a. Anal cell closed Atherix. (Type A, ibis, Fab.) 
h. Anal cell open Symphoromyia. {—Ptiolina, auctt. ,* 
type Atliei'ix melcena, Meig.) 
Jaennicke (Berl. ent. Zeitscbr. 1867, pp. 96-100) discusses the geo- 
graphical range, variation, and synonymy of the European species of this 
family. Ho regards Leptis strigosa (Meig.) as a var. $ L. scolopacca (Linn.).

EMPIDiE. 
Empis. In a series of three papers in the Berliner ent. Zeitscbr. for 1867, 
H. Loew subjects the species belonging to certain sections of this genus to a 
critical revision. The first of these (/. c. pp. 1-10) relates to the species 
related to Empis ciliata (Fab.), to which Loew refers E. nigerrima and E. hirta 
(Loew) of kno^vn species, and 3 new species here described by him. A 4th new 
species {E.pilosa) is also characterized as being nearly allied to the preceding 
in its general characters, although its halteres are yellow. The second section 
discussed by Loew {I c. pp. 11-24 and 167-160) is the group of species allied 
to E. stercorea (Linn.), under which he indicates and characterizes 11 Euro- 
pean species, of which the following were' previously described : — E. stercorea 
(Linn.) inch E. stigma (Meig.), E. punctata (Meig.)=jF. ignota (Meig.), E. 
trigramma (Meig.), E. lutea (Meig.), and E. parvula (Egg.). E, punctata 
(Fab.) is said by Loew to be distinct from the species originally described by 
Meigen under that name, and identical with that referred by Zetterstedt to 
E. testacea (Fab.). It is described as new by the author, who also charac- 
terizes E. testacea (Fab.) from a specimen said to have been determined by 
Fabricius {l.c. p. 168). The author also indicates 2 species {E. dispar, 
Scholtz, and E. mesogramma, sp. n.) which in their general characters seem 
to approach the E. stercorea group, but differ in certain points. E. meso- 
gramma belongs to the section of E. nigricans, to which Loew (/. c. p. 24) 
refers 12 other European species, namely : — E. variegata (Meig.), affinis 
(Egg.), confusa (Loew), macidata (Fab.), apicalis (Loew), rard (Loew), ma- 
cra (sp. n.), meridionalis (Meig.), nigricans (Meig.), coqnata (Egg.), discolor
