Genera and Species of the family Pyralidae. 31 



PoLiosTOLA, gen. nov. 



Type phycitimorpha. 



Proboscis well developed; palpi obliquely upturned, just ex- 

 tending beyond frons ; first and second joint of equal length, covered 

 with long scales in front, third joint less than half of second, obtuse 

 and covered with scales ; frons rounded, smootlily scaled ; maxillary 

 paljDi small, filiform ; antennae of male with a tuft of scales on front 

 of first joint, serrate and with two rows of cilia, longer than thickness 

 of shaft and placed in bundles at each joint, diminishing towards 

 tip ; in female the cilia are about half of shaft ; mid-tibia with two 

 rounded bushy tufts of scales, mixed with some hairs; hind- tibia 

 fringed with hairs on upperside and with two pairs of spurs of which 

 the outer spur is a little over half of mner spur. Fore-wing rather 

 broad, costa somewhat rounded, apex, termen and inner margin 

 rounded; 16 well forked at base; cell a little over half of wing; 

 vein 2 from | of lower median ; 3 and stalk of 4, 5 from lower 

 angle; stalk of 4, 5 nearly J of 4; discocellulars erect, curved; 



6 from below upper angle ; 7, 8, 9 stalked and from upper angle ; 



7 from nearly J of 9 ; 8 from nearly middle of 9 ; 10 from well 

 bej^ond ujjper angle and slightly approximated to stalk of 7, 8, 9 ; 

 11 and I upper median, curved towards 10 at base; 12 jDarallel 

 to upper median and vein 11. Hind- wing large, semicircular; 

 la curved; lb straight; Ic slightly curved and parallel to vein 2; 

 cell short, less than half of wing owing to the discocellulars curving 

 much inwardly; lower median from beyond middle of wing; 2 

 from I of lower median ; 3 shortly stalked with stalk of 4, 5 and 

 from lower angle; 4, 5 stalked for nearly |^ of 4; upjDer median 

 far less than half of wing ; 6 from upper angle, very shortly stalked 

 with 7 and curved towards 5 ; 7 curved at basal thii-d towards 8 ; 



8 anastomosing with half of upper median, then free and approxi- 

 mated to 7 beyond upper angle; lower discocellular very oblique 

 inwardly and long, upper discocellular oblique outwardly and only 

 half the length of lower discocellular. 



This genus is near Pyralis, but the palpi are rather 

 shorter, second joint with scales in front and less curved; 

 cilia of male antennae very long; hind-tibiae with fairly 

 long hair above ; fore- wing with vein 3 from angle ; hind- 

 wing with 3 from angle, even slightly stalked with stalk 

 of 4, 5; 6 very shortly stalked with 7, almost from a 

 point.
