np:w genera of south American moths. 



Bj^ Harrison G. Dyar, 



CuModian of Lepid<i}>tera. 



The collections of the United States National Museum have been 

 lately enriched l)v the South American moth.s presented l)y Mr. 

 William Schaus, probably the ])est collection of South American 

 Macroheterocera that has been formed. A large number of the 

 species are undescribed, particularly from Mr. Schaus's latest captures 

 in Guiana. The following- papers by Mr. Schaus and Mr. Warren 

 characterize a part of them; it is expected that other descriptions 

 will follow. A few new genera, referred to in Mr. Schaus's paper, 

 have been described, and appear herewith. I have also made synoptic 

 tables of genera for several families, which havel)een inserted in their 

 proper places in Mr. Schaus's article. Sir George F. Hampson has 

 kindly verified the new genera in the Syntomidaj and Lithosiida\ 



Family SYNTOMID^E. 



Genus SAURITINIA, ne\Ar genus. 



Palpi upturned to vertex of head; proboscis well developed; antennte 

 bipectinate, the branches long in the male with bristles at extremity; 

 tibia? with the spurs small. Fore wing with vein 8 from before angle of 

 cell; 4, 5 from angle; 7, 8, 9 stalked, 10 from cell before angle, joined 

 to the stalk to form a long accessory cell; 11 from the cell. Hind wings 

 with the cell moderate; veins 2, 4 from angle, 3 from 2 near margin; 

 5 obsolescent from lower third of discocellulars; 6, 7 from upper angle.

Genus METACROCEA, new genus. 



Palpi upturned to vertex of head; proboscis well develo[)ed; antenna 

 ])ipectinatc with short branches in the male with bristles at extremity; 

 tibife with the spurs moderate; abdomen with the second segment 

 constricted. Fore wings with vein 3 from near angle of cell, 4, 5 

 from angle, 6 from shortly below upper angle, 7, S, 9, 10 stalked, 11 

 from the end of the cell. Hind wings with the cell long; 2 from long 

 before the angle of the cell, 3, -l stalked; 5 strong, from well above 

 angle of cell; 6, 7 very shortly stalked.
