and Mycctophilina, the latter again divided into 7 subgroups. The total 
number of known species amounts to 694 (Schiner describes 6 new species, 
which do not appear to be taken into the account here), of which 671 belong 
to the European fauna, and 123 are exotic (America 105, Africa 5, Asia 7, 
Australia 5, unknown 1). The only established exotic genera which are not 
represented in Europe are Cncphccophila (Phil.), Dionomm (Walk.), and 
T?lat.yroptylon (Westw.). To these must be added Schiner’s P5eMc?oscm? «, 
the only species of which is from Columbia. 
HhyphuSj regarded by Schiner ns the type of a distinct family, includes 
11 described species (5 Kuropcan, 5 American, and 1 Australian). Two new 
species from llrnzil and Now Zealand are described by Schiner {1. c. p. 48). 
Scinrina;. Winnortz in his monograph of this group gives the following 
table of the genera admitted by him (p. 11) : — 
A. Flagellar joints of antennm cylindrical, pedunculated or not pedunculated. 
1. Wings longer than abdomen, their surface microscopically hairy ; wing- 
lobes more or less developed ; joints of antenna3 hairy. 
SciARA (Meig.). 
2. Wings as in Sciara, but their surface distinctly hairy. 
Trichosia, g. n. 
3. Wings as in Scia?'a ; cubitus united with the costal by a radial vein. 
Cratyna, g. n. 
4. Wings claviform, their surface microscopically hairy ,* antennse of cf 
pedunculate, with whorls of hairs Corynoptera, g. n. 
5. Wings narrow, shorter than abdomen, their surface microscopically 
hairy Bradysia, g. n. 
6. Wings and halteres wanting Epidapus (Hal.). 
B. Flngcllar joints of antennno ovate and with long stalks in J, cylindrical 
and without stalks in 9 • 
7. Wings as in Sciara, but the large fork enlarged at the base and its 
branches undulated Zygoneura (Meig.), 
By far the greater number of the species (173 out of 186) belong to the 
old genus Sciara, of which, indeed, the others are for the most part but dis- 
memberments. 
riesiastina annulata (Meig.) and P. apicalis (Winn.) are g and 9 of the 
same species, according to Kowarz, Verh. zool.-bot. Ges. in Wien, xviii. 
p. 213.
