 Antennte 14-jointed (2 x 12); joints iiediceled, subcyliudrical, and subequal, each 

 joint with two whorls of short and delicate hairs, a whorl at each end of the joint, 

 the hairs of the posterior whorl being somewhat longer than those of the anterior.

INSECTS INJURIOUS TO THE WITCH HAZEL. 



Hamamelis virginica. 



1. Gracilaria siqierbifrontella Clem. 



The larva (says Clemens) may be found in the middle of July, in 

 cones, on the leaves oi Hamamelis virginica (witch hazel), and the imago 

 appears early in August. This insect must approach very closely the 

 European swederella. 



Larva. — The head of the larva is pale green ; body pale green, darker-colored by 

 the ingesta, with the tenth ring whitish, and the cervical shield pale brown. 



Moth. — Labial palpi yellow, tipped with brownish. Antenuaj dull yellow, with 

 very faint brownish rings. Head stramineous, tinged with reddish-violet on the fore- 

 head. Thorax stramineous, with teguise externally striped with reddish-violet. 

 Forewings beautiful reddish-violet, with a shining stramineous patch on the inner 

 margin at the base, and a large costal triangle of the same hue, reaching almost 

 across the wing, and extending along the costa from the basal third, nearly to the 

 apex. Hind wings blackish gray; cilia dark fuscous. (Clemens.) 



2. Catastega hamameliella Clem. 



The larva constructs a little, short tube of frass along the midrib of 

 the leaf of witch hazel, Hamamelis virginica^ during the latter part of 

 September. The tube is begun in the angle made by a vein and the 

 midrib, and the triangular space between them is covered with a thin 

 web of silk, having beneath it the tube. (Clemens.) 



Larva. — The larva is nearly cylindrical, slender, with the head pointed. It is of a 

 uniform, rather pale-green color. (Clemens.) 



The following insects also occur on the witch hazel :
