ELEMENTARY ENTOMOLOGY 



from the shapes of the cases. Nearly related to them are the little 

 clothes moths, the plague of every housekeeper, which feed on 



woolens, furs, etc. 

 There are several 

 species: one makes 

 a case of bits of 

 food fastened to-

 small moths which 

 frequent the house 

 by the broad fringe to the wings already mentioned. Another mem- 

 ber of this family which is a serious pest of stored corn in the 

 South is the angoumois grain-moth 

 (Gelechia cerealelld), whose larvae 

 live in the kernels of corn and annu-

 The leaf-rollers (Tortricidae). Here 

 and there on various shrubs and 

 plants will be found leaves which 

 have been rolled up and fastened 

 together with silk by a little cater- 

 pillar living within. Most of this is 

 done by the leaf-rollers, which are 

 the most characteristic of the family 

 Tortricidae, though by no means all 

 leaf -rollers belong to this group. The 

 oblique-banded leaf-roller (Arc/tips 

 rosaceana) is found commonly on 

 roses and various . fruit trees, occa- 

 sionally becoming injurious, while its
