developed from worms and chrysalids remaining in tlie ker- 

 nels. The next June, a swarm of moths appeared in the 

 jar, in which they continued to propagate three years, suc- 

 cessively, producing moths in considerable quantities in June 

 and in August, with a smaller number at various inter- 

 mediate times, except during the depth of winter. 



These corn-moths, as already stated, were rather larger 

 than those from the wheat, the wings of some of them 

 expanding nearly six tenths of an inch.* The head is 

 smooth, and not tufted. The antennae are thread-like, with 

 distinctly marked joints. The feelers are long and curved 

 upwards ; the terminal joint naked, acute, and blackish near 

 the tip ; the second or middle joint rather shorter and thick- 

 er, hairy beneath, and blackish on the outer side ; the basal 

 joint very short and hairy. The tongue makes several 

 spiral turns, and, wlien extended, is about half the length 

 of the antennffi. The body and fore wings are of that tint 

 of pale brownish-gray which the French call coffee and 

 milk color, and they have the lustre of satin. The fore 

 wings are long and narrow, and are pointed at the end ; 

 together with their wide fringes, they are more or less 

 sprinkled with blackish dots, especially near the tips. The 

 hind wings are blackish, with a leaden lustre ; they are 

 narrow, and are very suddenly and obliquely contracted to 

 a point at the tips ; they are entirely surrounded with a 

 blackish fringe, which is wider on the inner margin than 

 the wing itself. They are folded lengthwise, when at rest, 

 beneath the upper wings. The fore legs are blackish, and 

 the hindmost legs are fringed with long hairs on the inner 

 side. Tlie chrysalis is obtuse at each end ; the tail sur- 

 rounded with a few minute points, three of which are larger 

 than the rest; the rings of the body are smooth, or not 



* Mr. Curtis, probably through inadvertence, has stated that Butalls cereahUa 

 " expands rather more than one inch." Half an inch is the true measure. See
