markings, the largest at the origin of Rs, with numerous other marks in all 

 the cells; a series of five subcqual oval spots in cell 3nd A. Venation as in 

 PI. 2, fig. 8. 



Abdominal tergitcs brown, sternites dull yellow, the extreme lateral margin 

 brown. 



In some specimens the only mark on the yellow femora is the broad sub- 

 apical brown band.

In my key to the American species of Epiphrag>na> this would nm 

 down to solatrix Osten Sacken of the eastern United States, from 

 which it differs in the much more ocellate character of the wing pattern 

 and other characters. 



Genus OROMYIA new genus, 

 (non Oreomyca Pokorny, Wien. Ent. Zeit., Vol. 6, iSS-). 



Antenna: of the male elongated, the scapal segments greatly swollen, globu- 

 lar, the elongate first segment of the fiagellum arising abruptly from the last 

 scapal segment, flagellar segments much elongated, the whole antennae about 

 as long as the body; there are only 12 antennal segments in my unique speci- 

 men, but the total number is very probably 16. Tibiae with two long, slender 

 spurs. Wings with subcosta short, ending opposite the origin of the radial 

 sector; the sector is short, arcuated; R, short, oblique, crossvein r lacking. 

 Male genitalia with the gth sternite produced caudad into a conspicuous lyri- 

 form plate. 



Type of the genus, Oromyia lloydi new species. 



In my key to the Limnophiline genera^ Oromyia Wduld run down 

 to Phyllolabis Osten Sacken^* of the western Nearctic fauna, which is 

 presumably its nearest ally, both genera agreeing in the lack of cross- 

 vein r and cell M^. They may be separated by the following key : 



I. Subcosta very long, ending opposite the fork of Rs; R.. not oblique and as 



long as /?,.j ; crossvein m prominent as long as r-m ; basal deflection of 



Ch, very far distad, so that Cu and M do not fuse. Male genitalia with 



the 8th sternite bearing a pale foliaceous appendage, broad at the base,
