This genus is probably nearest to Zea, Distant, of which the " Hes- 

 peria " mytlieca of Hewitson is the type. Zea has never been fully 

 diagnosed, the only characters given are as follows : — " Forewing. 

 Outer margin subequal [instead of a little longer] in length to inner 

 margin ; upper disco-cellular nervule longer than lower ; moderately ob- 

 lique ; base of second median nervule about twice as far apart from that 

 of the lower as from that of the upper median nervule. Hindwing. 

 Outer margin sinuatedor more or lesslobately produced near anal angle." 

 These characters are drawn up from a female specimen. But the type 

 species of Zela may instantly be known from the type species of Zea^ if 

 Mr. Distant's figure is to be relied on, by the hindwing being far shorter. 

 Zela is also allied to the genera Hidari, Distant, and Unkana, Distant,* 

 but may at once be distinguished from these by the middle disco-cellular 

 nervule of the forewing being upright instead of strongly inwardly 

 oblique ; the outer and inner margins of the forewing also are of equal 

 length, in both these genera the inner margin is much shorter than 

 the outer. Mr. Distant says that the outer margin in Zea is subequal 

 (instead of a little longer) in length to the inner margin, but according 

 to my view of measurement (taken from his figure of the type species) 

 the outer margin is considerably longer than the inner. The genus 

 appears similar to Perichares, Scudder, confined to tropical America, as 

 regards the secondary sexual characters. In general appearance it 

 most resembles species of the genus Matapa, Moore. 



44. ZELA ZEUS, n. sp., PI. Q, Fig. 57, $. 



Habitat : Pulo Laut, Borneo ; N.-E. Sumatra. 



Expanse : #, 1*7 ; 9, 1*8 inches. 



Description : Male. Uppeeside, both wings dark shining hair- 

 brown. Forewing with four hyaline shining stramineous spots : — an 

 oval one touching the median nervure towards the outer end of the 

 discoidal cell, a small round one in the subcostal interspace (absent in 

 Sumatran specimens), a round one four times as large as the last-named 

 spot towards the base of the second median interspace, a reversed 

 comma-shaped spot posterior to the last in the first median interspace, 

 the three last-named spots in a straight line ; the sexual brand placed 

 just within the posterior spot deep black, inconspicuous. Cilia 



* Captain Watson has sunk this genus under Erionota, Mabille. ■
