 discal greyish-white and black-speckled denticulated lines, a less prominent submar- 

 ginal line and marginal black dots ; reniform mark indicated by greyish-white dots ; 

 male with a large rounded tympanistic depression in middle of the cell : hindwing

Genus ILATTIA. 

 Ilattia, Walker, Catal. Lep. Het. B. M. xvi. p. 208 (1858). 

 Wings small : forewing short, triangular ; cell extending to half length of the 

 wino- ; in the male the subcostal and median veins are slightly curved before the 

 first branches, and within the cell is a rounded tympanistic sac, which is smooth, 

 depressed in the middle on the upperside, and on the underside is bordered along 

 its inner end by a fan-like lappet of broad plumose scales ; first subcostal branch 

 emitted at one-half before end of the cell, second at one-sixth, fifth from end of the 

 cell and touching the third near its base ; discocelkdar recurved, radials from near 

 upper and lower ends ; middle median at one-eighth and lower median at one-half 

 before end of the cell ; submedian slightly curved : hindwing short, very broad ; cell 

 less than half length of the Aving ; two subcostals from end of the cell ; discocellular 

 oblique, concave, radial from below the middle ; two upper medians from end of the 

 cell, lower at one-fourth before the cud. Body moderately slender, abdomen rather 

 lonf, thorax clothed with broad spatular scales ; palpi projecting to level of vertex, 

 first and second joints smoothly sipiamose, third lanceolate; legs long; antenna 

 setose. 



Differs from Berresa in the triangular form of forewing, the different position 

 of the tympanistic sac, as well as in the relative positions of the veins in the male, 

 the more slender and longer body, and less robust palpi.
