Key to the Genera of the Subfamily Epallaginae 



1 (lo). Wings petioled not more than one-half way from the wing base to the 

 arculus. Quadrangle not more than four times as long as broad; with not more 

 than two or three cross-veins. Area posterior to Cu2, at its widest point, at least 

 one-third the width of the wing at that point with several sectors beyond M A . . . 2 



2 (5). Quadrangle with one or two cross- veins; subquadrangle usually with more 

 than two. In the hind wing the basal space generally not more than twice as 

 long as the quadrangle 3 



3 (4). Area back of anal vein with only one row of cells to beyond MA, at least in 

 the fore wing. Stigma with anterior proximal angle away from the wing-base. 

 In the fore wing the antenodal cross-veins are less numerous than the postnodal. 

 India to China and Malaysia. (Fig. 21.) Pseudophaea' Kirby, 1890 



(Euphaea Selys, 1840) 



4 (3) . Area back of anal vein with two rows of cells to beyond MA. Anterior prox- 

 imal angle of stigma toward the wing-base. Antenodal cross-veins more numer- 

 ous than the postnodal. Indo-China to Malaysia. (Fig. 22.) 



Dysphaea Selys, 1853 



5 (2). Quadrangle without cross-veins; subquadrangle usually with two or fewer. 

 Basal space generally more than twice as long as the quadrangle 6 



6 (7). Basal radial space closed and free. India. (Fig. 23.) 



Bayadera Selys, 1853 



7 (6). Basal radial space not closed in both wings 8 



* The genera Heterina and Lais now contain so many species with so many intergrad- 

 ing characters, that it is impossible to fix upon any clearly defined characters for the sep- 

 aration of the two genera, without a more detailed study than I have been able to give 

 them. Many species of Heterina have several rows of cells back of the anal bridge in the 

 forewings, while Lais is supposed to have but two such rows. However, in specimens of 

 H. donna, vulnerata, crtientata, tricolor, titia, caja, macropiis, etc. some have only two. 

 In many species of Hetaerina the males have the base of the wing red. Beyond these 

 characters further ones are unknown to me. 



' The genus Paraphaea, Martin, 1903, would seem, from the description, in the Bulle- 

 tin of the Museum of Paris 1903, to come in this part of the key, but the description is 

 too incomplete to use for the key. The translation reads as follows: "This new genus is 

 created from a single specimen from Manilla and belonging to the Museum of Paris. 

 It is of the Legion Euphaea of M. de Selys. The basal space is free, the median sector 

 (M3) branches from the principal (Mi) toward the end of the quadrangle; the feet are 

 quite long, the body slender, the fundamental color of the body red, but the ventral 

 surface of the thorax entirely black. The nodus is placed exactly at the middle of the 

 wing. The superior appendages are slightly bent not dilated, the inferior small; the 

 posterior margin of the tenth segment bears a papilla." 



Under the specific description of P. barbata: "Abdomen 55 mm.; lower wing 41 

 mm.; 24 antenodals and 24 postnodals to the upper wings; 24 antenodals and 24 post- 

 nodals to the lower wings. Wings hyaline, slightly tinged with safifranin, the distal tip 

 of the stigma bordered with brown; the stigma brown, covering seven cells, broad at the 

 middle, narrowed at the two ends which are pointed, especially proximally. Quadrangle 

 small, short, crossed."
