 verse white line on first and second abdominal segments; a median pair 



of small black tubercles on each

The perfect insect is a pretty Pyralid with a spread of wing of from one 

 inch to one inch and one-fourth (Fig. 6). It may be recognized by its 

 rich reddish-brown fore wings with darker shades at the base, on the 



outer margin, and along the veins, together with 

 bright reddish-yellow hind wings withadaiker 

 apex. On the under surface, the apex of the fore 

 wing and the fore margin of the hind wing is 

 reddish-purple; there is also on the fore wing 

 an irregular blackish spot at the tip of the 

 discal cell and a small one near its center. 

 The males are most easily recognized by their smaller size, 



Guenee has expressed his beHef that M. reversalis may be identical 

 with the diversalis of Duponchal, and has compared it in his description 

 with that species. His description is as follows : 



Smaller. The front wings are narrower, a little less rounded at the 

 terminal border, of a lively but pale ferruginous-red, with the costal margin 

 more red, and the fringe slightly tinted with black. The posterior trins- 

 verse line is wholly punctiform in its entire length. The reniform spot is 

 blackish. The hind wings are pale yellow, unicolored, with a concolorous
