 and running closely approximate to M 3 for a considerable distance, but not fusing 

 with it. 



The "lame (figs. 391 to 396) are very generally leaf rollers and crumplers, often 

 living in a tube of silk mixed with frass, within the folded leaf; several species 

 eat stored food etc., and become serious pests. They are distinguished from most

 black with a white center. 



The subfamily seems to be derived from the Pyralidinse, perhaps through the 

 Epipaschiinae; the genus Omphalocera is a synthetic one, with the venation of 

 the Pyralidinae, the sex-scaling on the wings most characteristic of the Epipa- 

 schiinae, and a common Phycid type of male antenna. Its larva is also rather 

 Phycid than Pyraline. 



The middle discocellular of the hind wing is of four principal types: 



( 1 ) Discocellular curved strongly above middle, the lower part long, oblique, 

 meeting lower side of cell at a sharp angle, well beyond the origin of Cu!, so that 

 M 2 and M 3 appear connate. This type is represented by the genus Trachycera in 

 Texas, but appears not to reach our area. 



(2) Discocellular strongly curved, the lower part somewhat longer, meeting 

 lower side of cell at a sharp angle not far from origin of CUj (normally a little
