p. 188. As to the whole arrangement, it has been entirely super- 
seded by Latreille himself in his later works. 
P. 167, at the bottom, the following species of Otenophora has 
been accidentally omitted: 
ornata Meig. — Triest; Greece (collect. von Roeder); England 
(Curtis); Vienna, in the Prater (Rossi). 
P. 168. After Ct. vittata M., add 
Syn. amoena Loew (the deser. of the male only) Beschr. eur. Dipt. 
Ep: 3. 
To the localities add: Eastern Prussia, Königsberg (Bachmann). 
P. 178, line 14, from bottom, for three read two. 
P. 178, line 7 from bottom should read thus: 
The other form is Ozodicera. 
P. 178, 179, 180 strike out the whole paragraph about Ctedonia, 
as well as this name in the Alphabetical Index, on p. 188. 
P. 185. Macromastix. 
Some south-american Tipulae with very long filiform antennae 
come very near the genus Macromastix, but must not be confoun- 
ded with it. | 
One of these forms is the species described by Wiedemann as 
Megistocera braziliensis (A. Z. I, 554). I have already alluded to 
it (Berl. Ent. Z. 1886, p. 184) as being perhaps a Pachyrrhina with 
an unusual development of the antennae.. I find several specimens 
in the Berlin Museum, which belong to that, or a closely allied spe- 
cies. The male forceps is slightly club-shaped, apparently Pachyr- 
rhina-like. The antennae of the female are much shorter than those 
of the male. not longer than the thorax; the ovipositor has a pecu- 
liar structure, quite different from the usual type of a Tipula; the 
usual valves are replaced by coriaceous, hairy organs, difficult to 
study in dry specimens. 
The other form approaches Maeromastix much more than the first. 
The long filiform antennae of the male are beset with a dense, delicate 
erect pubescence on both sides, and not on the underside only, as 
is the case with the species of Macromastix. The tubercle of the 
front is much less conspicuous, the rostrum much shorter; nasus 
distinet; the male forceps is of a simple structure: it consists of ra- 
ther long basal pieces, with appendages folding like the blade of a 
penknife; the forceps protrudes here much more than in Maero- 
mastix. The number of the joints of the antennae is very difficult 
to count; the venation is like that of a Tipula; the rhomboid cell
