8. Labial palpi often upturned; maxillary palpi (fig. 339, etc.) 

 very rarely large and triangular (Loxostegopsis), and in that 

 ■ case with R 3W , R , and M 1 closely approximate, p. 541. 



Pyraustinse. 

 Subfamily SCHCENOBIIN^ 

 {Crambince, in part) 



Male antennae simple, laminate, except in a few exotic species; palpi long, almost 

 always porrect; maxillary palpi large, triangularly tufted; tongue very weak or 

 absent. Thorax often with vestiture of fine loose hair. Fore wing ( fig. 298 ) with 

 outer margin curving more evenly into inner margin than in most Crambinse ; R with 

 all five branches preserved; R 5 free in our species, and R 2 frequently free; 1st A 

 a developed tubular vein at margin, with interspaces of the normal width between 

 it and the veins above and below it; usually curving down to inner margin; 2d A 

 almost always ending in inner margin; 3d A short and free, obscure. Hind wing 

 with a slight fringe on base of Cu, or none; female with frenulum of several 

 bristles; Sc and R anastomosing beyond end of cell; Mj from upper angle of 

 cell or shortly stalked with R; dorsal veins all present and normal.

The Schcenobiinse are a small group of more -or less aquatic moths, much like 

 the Crambids, but weaker-winged. The wings are normally more loosely rolled in 

 repose. The moths are locally common in wet places. The larvse are hardly 

 known, structurally, and are borers in marsh and aquatic plants. In one European 

 genus, Acentropus, the larva is completely aquatic and the female of the summer 

 brood is wingless and lives under water.
