vol. iii. pp. 543-644. December 1864. 
In this elaborate paper Walsh proposes to do for the numerous 
galligenous insects of the North- American willows what he has 
already done for the Cynipideous gall-flies of the oaks of the same 
country. The first part is devoted exclusively to the Gall-gnats 
of the genus Cecidomyia. A notice of Walsh^s general remarks 
on the phenomena presented by the life-history of these insects 
will be given on the completion of the memoir. 
ScHiNER (Verb, zool.-bot. Ges. in Wien, Bd. xiv. pp. 193- 
200) proposes a new nomenclature for the veins of the wing in 
the Diptera. He indicates that in a few cases three, but in 
most instances only two, longitudinal veins spring from the base 
of the wing, and that these by tlicir division give rise to the 
other longitudinal veins. The third of these veins, when pre- 
sent, is very small; for the others Schiner proposes the names 
of vpper and loiver primary veins. They are always united by a 
transverse vein, which is usually perpendicular to the long axis of 
the wing, but is sometimes oblique and curved, and then less easily 
distinguishable. The outer margin of the wing is occupied by the 
costal vein ; the upper primary vein may be called the subcostal. 
From the subcostal vein springs the second, and from this the third
