Genera and Species of Pyralidas. 97 



mark filled up with black. Hind wings cinereous, with a 

 very indistinct denticulated outer line, and the row of dots 

 before the fringe as in fore wings. Head and thorax con- 

 colorous with fore wings; abdomen dark cinereous, with the 

 segmental divisions paler. Underside of fore wings deep 

 cinereous, of the hind wings dull straw-colour with the 

 markings darker ; costa of fore wings yellowish from middle 

 to apex. 



Expanse of wings 18 millim. 



Several from the Khasia Hills. 



Genus Eurycreon, Led. 

 Eurycreon ? rubralis, sp. n. 



Fore wings reddish brown, thickly scaled, with no markings 

 but an indistinct exterior line, slightly denticulated, which 

 rises on the costa at three fourths, from an oblique dark pale- 

 edged streak ; fringes very wide, red-brown, with a line of 

 darker red dots at the base, those near the apex being edged 

 with whitish. Hind wings whitish, becoming rather reddish 

 towards apex and hind margin. Head, thorax, and abdomen 

 concolorous. Underside glossy pale reddish ochreous. 



Expanse of wings 12 millim. 



One male from the Khasias. 



The forehead is much produced below, forming a shelf 

 which is in the same plane with the top of the much pro- 

 longed and stout palpi ; the antennas are thick, lamellate. 

 Having only one example, and that somewhat damaged, I 

 refrain from making a new genus for the species, as will 

 probably have to be done later on. 



Genus Pachyzancla, Meyr. 

 Pachyzancla honestalis, sp. n. 



Fore wings pale fawn-colour, tinged with rufous ; the 

 costa broadly and the hind margin diffusely darker tinted ; 

 markings fuscous ; an oblique basal line, a curved sinuous 

 exterior line, and two cell-spots ; hind margin, immediately 

 before the pale basal line of fringes, darker. Hind wings 

 paler, semidiaphanous, with dark discal spot and central line ; 

 a dark shade along the hind margin. Head and thorax 

 concolorous with fore wings, abdomen with hind wings. 

 Underside paler and duller, with the markings indistinct. 



Expanse of wings 20-22 millim. 



Khasia Hills.
