Pterophorina, and Orneodina, and a few supplementary genera and species omitted in 
the other volumes dealing with the Heterocera. The Tineina are grouped under 22. 
Families—Lavernide, Gelechiade, GEcophoride, Ethmiade, Blastobaside, Stenomide, 
[ Aigeriade], [Cosside], Arrhenophanide, Sparganothide, Olethreutide, Tortricide, 
Phaloniade, Carposinide, Hemerophilide, Coleophoride, Heliodinide, Hypono- 
meutide, Phyllorycteride, Tineidz, Acrolophide, and Nemophoride. ‘Two of them, 
the Aigeriade and the Cosside, were previously dealt with in detail by Mr. Druce 
in Vol. I., their true affinities with the Tineina not having been recognized at 
that time. Lord Walsingham, in his Introduction, alludes to the great assistance 
he has received from Mr. J. H. Durrant in the preparation of this Volume, which 
is illustrated by ten coloured plates, representing 350 species of Tineina. 
43, Diprera. Vol. I.: by Baron C. R. Osten Sacken, the Supplement by S. W. Wil- 
liston, J. M. Aldrich, W. M. Wheeler, and A. L. Melander: Cecido- 
myiicdee—Em pide. 
Twenty-four Families of Diptera are enumerated in this Volume—Cecidomyiide, 
Mycetophilide, Bibionide, Simuliide, Blepharoceride, Culicide, Chironomide, 
Psychodide, Tipulide, Rhyphide, Stratiomyide, Tabanide, Chiromyzide, Leptide, 
Xylophagide, Acanthomeride, Mydaide, Nemestrinide, Bombyliide, ‘Therevide, 
Cyrtide, Asilide, Dolichopodide, and Empide. Osten Sacken’s work was published 
in 1886-1887. ‘The Supplement by the American writers Williston, Aldrich, Wheeler, 
and Melander was issued in 1900-1901, and the editorial Introduction in 1901, on 
the conclusion of the whole subject. The material examined by Osten Sacken was 
very meagre, and though more specimens from Mexico were available for the 
Supplement, yet it was insufficient to give more than a general idea of the Dipterous 
fauna of Central America. The present Volume, therefore, is merely a contribution 
towards the study of these insects, rather than a complete list of the forms actually 
inhabiting the region. Altogether, 977 species are enumerated, 330 of which are 
described as new. ‘The six coloured plates illustrate 120 species. 
During recent years the Mosquito fauna of Panama has been specially studied in 
the canal-zone by Mr. A. Busck, and his report has been published [Smithsonian 
Contributions, vol. lii. pp. 49-77 (May Ist, 1908)]. Many uew species of Culicidee 
from Panama and other places in Central America have been described by Theobald, 
Dyar, and Knab. 
44, Diprera. Vol. Il.: by F. M. van der Wulp: Qiéstride, Muscide, and Hippo- 
boscide. 
This Volume contains the enumeration of the numerous groups of Diptera known 
collectively under the name of Muscide, for which abundant Mexican material collected 
by Mr. H. H. Smith was available, but the work was only about half finished when the
