Empid/e. 
Pachymeria. Loew indicates (Wien. ent. Mon. Bd. viii. pp. 353-358) the 
difficulties in the way of dividing the old genus Empis into natural groups, 
and especially of limiting the genus Pachymeria satisfactorily. He also de- 
scribes the species, 6 in number, of which 3 are new, belonging to the typi- 
cal group of Pachymeria, allied to P. femorata (Fab.) : namely, P. palparis 
= scotica (Qm:t.)=^fcmorata (Walk.), 1. c. p. 360; P. femorata (Fab.) 
— ruralis QAdi^.^—quinquevittata (Macq.), 1. c. p. 362 ; and P.pudica (Loew) 
= P. tumida (Loew), 1. c. p. 364. 
Loew (Wien. ent. Mon. Bd. viii. pp. 237-255) publishes de- 
scriptions of the Austrian species of Ilemerodromia, 5 in number, 
including a new species. The known species are, H. precatoria 
(Fall.), with monostigma (Meig.), melanocephala (Hal.), and 
flavella (Zett.) as varietal synonyms, 1. c. p. 238 ; H. raptoria 
(Meig.), 1. c. p. 243; H. oratoria (Fall.), l.c. p. 244; and //. 
unilineata (Zett.), /. c. p. 247. The last portion of this paper 
(pp. 249-255) is devoted by Dr. Loew to a severe criticism of 
Schiner^s treatment of the genus in theDipteraof 
the ^ Fauna Austriaca,^ which appears to have been rather con- 
fused. The Austrian species cited by Schiner, H. flavella (Zett.), 
stigmatica (S chin.), and (Fall.), are regarded by Loew 
as varieties of a single species ; and he also points out several
