Soc Ent. Fr. (6) ii. pp. 1-22. 
The author discusses the characters of the Muscidce in general ; the 
genus Rceselia , Desv., is one of the Tachinides , and Tryptocera frontalis , 
Macq. (? = Actia tamia , Desv.), is much nearer Actia than Tryptocera. 
The classification of the Anthomyzidce is then discussed, and a table of 
genera given, a few new, but without indication of types. Lastly, the 
characters of the genus Ctenostylum aro discussed.

The larvae of the Leptidce, Bibionuke, Therevidce , Xylophagulcc, Asilidce, 
Dolichopezidce, and Fungicolce have thirteen ganglia, two cephalic, three 
thoracic, and eight abdominal. Some of the Fungicohe , however, as 
Rhyphus , have only twelve, owing to tho fusion of the last two abdominal 
ganglia. In the larvae of tho Tabanidce , there are only sovon ganglia, one 
cephalic, one thoracic, and five abdominal. 
Brauer, F. Uber Latreille’s Segment mediaire und das Metathorax- 
Stigma der Dipteren. Zool. Anz. v. pp. 306 & 307. 
Tho author corrects his former opinions. There is no “ segment 
mediaire ” in Dip ter a \ what Latreille regarded as such is partly the free 
mesophragma of the Tipulidce , and partly the metanotum. The thorax 
of Diptera is constructed like that of Cicadulce and Lepuloptera. A short 
description of the parts of the thorax (chiefly referring to the Tipulidie ) 
follows. All Diptera possess a metanotum, but the author’s former 
views as to the existence of a metascutellum are entirely erroneous.

Osten-Sacken, C. R. Diptera from the Philippine Islands, brought 
home by Carl Semper. B. E. Z. xxvi. pp. 83-120, 187-252. 
Semper’s collection contained about 250 species ; only 52 were pre- 
viously known from the Philippines. The fauna appears to be remark- 
ably specialized, but to exhibit considerable affinities with that of the 
Malay Archipelago. Many undetermined species are mentioned, without 
being described.
