vein 9 remote from 10, close to end of cell; vein 6 from upper 

 angle of cell : upper discocellular minute ; middle discocellular 

 erect, lower slightly inwardly oblique, the lower rather the longer ; 

 vein 3 well before end of cell, about equidistant from 2 and 4, and 

 twice as far from base of wing as from end of cell. Hind wing 

 triangular, hardly lobed at anal angle ; vein 7 three times as far 

 from" 8 as from" 6 ; discocellulars faint, erect ; vein 3 well before 

 end of cell, twice as far from 2 as from 4 ; vein 2 slightly nearer to 

 end of cell than to base of wing. Hind tibiae with two ])airs of spurs 

 and with a long tuft of coarse hairs attached near the proximal end. 

 E. yifjas, Mab., the type of Eurijpterus, is not in B. ^I., but as 

 the other two s})ecies, viz. lamchrea^ Butler, and coracinn, Butler, 

 which M. Mabille puts into his genus, are congeneric with deusinia, 

 Hewitsou, the type of Mthilla, therefore (jiyas also is presumably 

 an JEthilla.
