carried farther than in the other families (except in the 
Dyspteris division of the Hydriomenidae). In fact, in all 
of the forms known to the writer, the humeral angle ex¬ 
tends a considerable distance beyond the frenulum. In 
the fore wings there is also a more marked migration of 
the base of vein V a towards radius than occurs in other 
Geometrid families. All these characteristics lead us to 
consider the Geometridae the most specialized of the Geom- 
etrina. 
The Raspberry Geometer, SyncJilora glaucaria (Syn- 
chlo'ra glau-ca'ri-a).—The different species of green Geom- 
etrids resemble each other to such an extent that it is 
difficult to describe any one of them in a few words so that 
it can be surely distinguished. The wings of the Raspberry 
Geometer are of a delicate pale green color crossed by two 
lines of a lighter shade, and when expanded measure from 
one half inch to one inch, there being great variation in size 
of specimens. The larva is more easily distinguished on 
account of its curious habits. It feeds on the fruit and 
foliage of raspberry, but chiefly on the fruit. It covers its 
body by attaching to it bits of vegetable matter, so that it is 
masked beneath a tiny heap of rubbish. 
Family Auzatid^ (Au-zat'i-dae). 
The Auzatids (An-za!tids). 
Only a single species belonging to this family is known 
to occur in this country. This is a small moth with delicate 
snow-white wings which expand from three fourths of an 
inch to one inch. This is Eudeilinca Jierminiata (Eu-dei- 
lin'e-a her-min-i-a'ta). 
In the form of the body and in the structure of the wings 
(Fig. 344) the members of this family closely resemble the 
differs in important respects from the typical members of the family, and 
may belong elsewhere.
