far as I recollect by larvae, occurred in September on the lower side 
of the leaves of the red osier dogwood. (Walsh). 
Genus GLYPHINA. Koch. 
This genus differs from Schizoneura chiefly in the fact that the hind 
wings have but one branch vein. It may be defined as follows: The 
beak short; antennae short, not reaching beyond the tip of the thorax, 
transversely corrugated; six jointed, the two basal joints very short, 
the third longest, about or nearly equal to the three following; the 
sixth joint sometimes very short, while in other cases it equals the 
fifth. Front wings usually have the third vein once forked, but some¬ 
times the same species varies in this respect and occasionally presents 
an individual with this vein simple. Hind wings with one oblique or 
branch vein. Honey-tubes obsolete or wanting. 
Mr. Monell’s genus Colopha must be considered a synonym, unless 
we consider the slight variation in the length of the sixth joint as a 
generic character, which does not enter into the diagnosis of his genus. 
Koch evidently considered the fork of the third discordal vein of the 
forewing as characteristic of his genus, as he speaks of the simple 
form observed in Gl. betulce as exceptional and unfortunately figures this 
exceptional form. 
Thalaxes. Westwood, as modified, or rather as explained by Walsh 
is also a synonym. It is true that Westwood speaks of his species as 
a synonym of Vacuna Ileyd, but the number of joints in the antennae 
does not appear to have been relied upon as a character, the supposed 
normal position of the wings, when at rest, being apparently the gov¬ 
erning characteristic. 
Mr. Monell who makes Byrsocripta ulmicola. Fitch, the type of his 
genus, gives as a character,“wings in repose usually horizontal.” As I 
have elsewhere stated, when first taken from the galls the wings are 
often seen in a semi-horizontal position, but the appearance, even at 
this time shows that this is not their normal position, which is evi¬ 
dently erect.

This species forms the cone-shaped galls, so common on the upper 
side of the leaves of young white elms. These galls, which are often
