288 THE STUDY OF INSECTS. 



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 3 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, Synchlora 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 AuzATlDiE (Au-zat'i-dae). 

 The Auzatids (Au-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 Eudeilinea herminiata (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.
