Proboscis often absent or minute ; palpi porrect; the maxillary palpi well developed and triangularly dilated with scales. Fore wing with vein 7 present *; vein 1 a separate from 1 b. Hind wing with the median nervure pectinated, on upperside; vein 7 almost always anastomosing with 8. The larvae are usually grass or reed feeders. Of the subfamilies of Pyralidae that have the median nervure pectinated, tbe Crambince may be distinguished from the Phycitince and Anerastiince by the presence of vein 7 of the fore wings *; from the Galleriinee by vein 1 a being separate from 1 b instead of forming a fork with it, also by the labial palpi being well developed in tbe male instead of almost obsolete, and the maxillary palpi triangularly scaled; from the Oxychirotinee by having the outer spurs of mid and hind tibiae well developed instead of absent, and also by the very different shape of the wings. Whilst in the few genera of Pyraustince and Scopariince that have the median nervure pectinated, the very different form of the labial and maxillary palpi will at once serve as a distinction. Key to the Genera. A. Hind wing with vein 6 from upper angle of cell. t a. Fore wing with veins 7, 8 stalked, 10 from cell. a1. Hind wing with the upper margin of the cell approximated to 8; fore wing with the apical area not produced. a2. Both wings with vein 3 present. a3. Fore wing with veins 2, 3 stalked b3. Fore wing with veins 2, 3 from cell. a*. Thorax below and coxae smooth. a5. Fore wing with veins 10, 11 stalked b5. Fore wing with veins 10, 11 from cell... 6*. Thorax below and coxas hairy b2. Both wings with vein 3 absent J1. Hind wing with the upper margin of the cell remote from 8; fore wing with the apical area produced to a rounded prominence b. Fore wing with vein 7 absent \ c. Fore wing with veins 7 and 10 from cell. a1. Palpi extending once to three times length of head. a*. Fore wing with veins 6, 7 from cell. a3. Frons rounded and not prominent. a*. Proboscis well developed; palpi with the 3rd joint clothed with hair. a3. Hind wing with veins 4, 5 from a point. b5. Hind wing with veins 4, 5 well separated at origin * Except in Culladia and Mesolia apistrigella. t In Mesolia apistrigella vein 7 of the fore wing is absent. j In a few specimens of Eschata 7 is shortly stalked with 8, 9. 1.
