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

 the cells; a series of five subequal oval spots in cell 2nd A. Venation as in 

 PI. 2, fig. 8. 



Abdominal tergites 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. 



Holotype, d", Popayan, March i, 1912 (by sweeping). 



Allotype, ?, Valle de las Papas, March 22, 1912. 



Paratypes, 3 cj', i 2, with the allotype. 



In my key to the American species of Epipliragma'^ this would run 

 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 Oreomysa Pokorny, Wien. Ent. Zeit., Vol. 6, 1887). 



Antenns of the male elongated, the scapal segments greatly swollen, globu- 

 lar, the elongate first segment of the flagellum 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 9th sternite produced caudad into a conspicuous lyri- 

 form plate. 



Type of the genus, Oroiiiyia lloydi new species. 



In my key to the Limnophiline genera- OroJuyia would run down 

 to Pliyllolabis 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 7?2+3 ! crossvein m prominent as long as r-m ; basal deflection of 

 Ci/j very far distad, so that Cn and M do not fuse. Male genitalia with 

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