Io6 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



denly contracted to a point near their tip ; the fringe of the same color, 

 jjurrounding the wings, and along the inner margin broader than the 

 wing itself. Beneath, both pairs of wings are of a leaden color. The 

 front pair of legs are blackish ; the hind legs have two prominent pairs 

 of spurs, and are fringed with long hairs. In Fig. 19, at c, an enlarged 

 view of the moth is given. The excellent figure is from Prof. Riley's 

 Report to the Department of Agriculture, for the year 1884, as is also 

 the preceding one. 



At e, a and h. in the figure, the egg, larva and pupa are shown. For 

 description of these stages the writings cited of Dr. Fitch, Mr. Webster 

 and Prof. Riley may be examined. 



Food-Plants. 



The most serious injuries of this insect have been to wheat, attacked 

 both in the field and in granaries. It also occurs in barley, in oats and 

 in corn. Mr. Glover has seen the moth flying about corn standing in 

 the field, in November, in Georgia, depositing its eggs in the ears. Ac- 

 cording to the same writer, it feeds also upon grass-seed {Eiitomolog. 

 Index to Anricnl. Reporfs — Anaeamjjsis, p. 4), although it is difficult 

 to see how it could do so consistently with its concealed habit of feed- 

 ing, and in all other cases, so far as known, at once burrowing into 

 the grain and feeding and transforming therein. 



Life-History. 



Under natural conditions there are two annual broods of this insect; 

 but within doors, in stored grain there are more, the number depending 

 upon the temperature of the apartments. 



The moths of the first brood make their appearance in May or June, 

 according to the latitude and temperature of the season, and seek the 

 grain upon which to lay their eggs — each moth depositing from sixty 

 to ninety minute eggs, of a bright orange color. Upon wheat and 

 similar grains these are usually placed in lots of twenty or more, in a 

 line or in an oblong mass, in the longitudinal furrow upon the side of 

 the grain. The eggs hatching in from four to seven days, the larva at 

 once burrows into it at its most tender portion, and continues to feed 

 upon the interior, packing its excrementa around it in the cavity made 

 by its feeding. In about three weeks' time it is full-grown, when it 

 measures about one-fifth of an inch in length. It then eats a hole out- 

 wardly for its escape when transformed into a moth, leaving only a thin 

 film, circular in outline, of the surface of the kernel to be pushed off at 

 its final exit. A thin cocoon of white silk is then spun within the 

 cavity, in which it changes to a pupa. After a short pupation the pupal
