in hairs, filiform, about half of second joint, first joint nearly half 

 of second joint ; maxillary palpi small, three jointed and triangu- 

 larly covered with haiis and scales ; frons rounded ; antennae with 

 a tuft on front at first joint, shaft in male serrate and biciliate, in 

 female almost simple, cilia very short ; tibia smoothly scaled, hind 

 tibia with some hairs and two pairs of spurs, outer spur about 

 half of inner spur. Fore-wing triangular, costa nearly straight, 

 apex well rounded, termen very oblique, slightly rounded, tornus 

 well rounded, inner margin straight, cell long, nearly f of wing; 

 \h apparently simple at base; 2, 3, 4, 5, 6, and stalk of 7, 8, 9, 



10 at nearly equal distances given off from the cell; greatest 

 distance between 5 and 6, shortest between 4 and 5; 7, 8, 9, 10 

 on a stalk of nearly half of 9 ; 7 from 8 just a little beyond 9 ; 



11 from I of upper median; 12 straight. Hind- wing sub- 

 triangular; costa well curved from f, apex rounded, termen very 

 oblique, nearly straight and roundly lobed at 16, tornus rounded, 

 inner margin straight; cell nearly | of wing; 2 from beyond | 

 lower median; 3 from |- 2 to 5; 4 absent; 5 from lower angle; 

 8 parallel to upper median and veiy little approximated to 7 



The triangularly scaled maxillary palpi are rather peculiar 

 to this sub-family, the only other genus known to me to 

 have such palpi is Sindris, but in that the labial palpi are 

 upturned and the venation of both wings is totally differ- 

 ent. I do not think, however, that this genus has any 

 affinity with Sindris, it is perhaps more related to Discordia, 

 which has the maxillary pali)i more strongly developed. 

 From this and Profeinia it differs in the coincidence of 

 veins 4 and 5 in hind-wing ; from the latter genus it differs 

 mostly in length of lappi, shape of wings and venation of 

 both wings; in wing-shape and general appearance it 

 mostly resembles Discordia. From this it differs in the 

 maxillary palpi, absence of vein 5 and in vein 9 of fore- 

 wing coming from 8 before 7, and 2-5 being far from each 

 other and at ecpial distance. In the hind-wing vein 8 is 

 very slightly curved towards vein 7 and is more remote 

 from that vein than in any other Pyralinae known to 

 me.
