LEPIDOPTERA : TORTRICID^E. 409 



Fabr., which expands from one inch to one inch and a 

 half, and the fore wings slope steeply and turn up at the 

 end ; the male is grayish, the fore wings scalloped on the 

 hind margin, glossed and streaked with purplish brown 

 on the outer edge, and marked with a few dark spots near 

 the inner margin ; hind wings light yellowish gray with 

 light fringes. The female has the fore wings longer in 

 proportion, less deeply scalloped, and the color darker. 

 By day bee-moths remain quiet about the bee-houses, 

 but at night they hover around the hives, into which they 

 enter and lay their eggs ; or, not succeeding in this, they 

 deposit their eggs upon the outside. There are two 

 broods in a year. The larvae feed upon wax ; they enter 

 the hive as soon as they are hatched, and work their way 

 in all directions through the waxen cells, and thus destroy 

 them. During the day they remain concealed in silken 

 tubes, which they begin to make for themselves as soon 

 as hatched. They enlarge these tubes as they increase 

 in size, and cover them with a coating of wax as a defence 

 against the stings of the bees, and thus they are able to 

 go on with their work of destruction with impunity. 



The Genus Crambus has the feelers long, wings oblong, 

 white and buff-yellow, sometimes ornamented with golden 

 spots. The species fly in the grass in great numbers, 

 and rest on the stems with the head downwards.
