Genus ZEA. 



Zea, Distant, antea, p. 



This genua is allied to the preceding in general characteristics and in having the upper disco-cellulftr 

 nervnle of the anterior wings a little longer than the lower; hut it strongly differs from Pirdana hy the 

 position of the median nervules of the anterior wings, the second of which has its hase only about twice 

 as far apart from that of the lower aH from that of the upper median nervnle* 



It is probable, looking at the many superficially allied but structurally or genetically 

 distinct species of Heaperiidtf, that in this family much generic separation must be made before 

 these butterflies can he rightly understood, or their distribution in any way studied ; and whilst 

 this generic separation can be effected by the recognition of such structural characters, as 

 may be clearly expressed in words, and capable of synoptical illustration with reference to other 

 genera, the work is necessary and fco be commended. But when a supposed genus is better 

 known by its name than separable by its characters, it becomes but a term of a catalogue and 

 an encumbrance to Science.* 



1. Yea mytheca, (Tab. XXXV,, fig. 7.) 



Hmperift mytheca, HewUson, Ann. & Mag. Nat. Hist, ser, iy. vol. 19, p. 81 (1877), 



Female. Wings above dark fuliginous-brown ; anterior wings with three pale yellow discal spots, 

 one in cell and two beneath F divided by the second median nervule, a fourth very small greyish spot 

 above upper end of cell. Anterior wings beneath as above ; posterior wings beneath with a very broad 

 silvery-white discal fascia commencing on casta and terminating near the submedian nervure. Body aud 

 legs more or less concolorous with wings, 



Exp. wings, 50 millim. 



Hab. — Malay Peninsula; Malacca (coil. Staudinger). 



The type, in the collection of Dr. Standinger, is here figured and described, and I am 

 much indebted to that esteemed lepidopterist for the loan of what I believe is at present 

 hli unique specimen, 



Genua MATAPA. 

 Matttpa, Moore, Lep, Ceyl, voh i, p. 168 {1861)* 



This genus is most readily recognised by the position of the cell to the anterior wings, 

 which is attenuated anteriorly. 



The male is described by Mr. Moore as having 11 an oblique discal slender linear glandular 

 streak of raised scales" to the anterior wings. 



- What would old Inane Walton Iihvp thoupht now, if possessed of the flame spirit nf admiration hh when lie wrote, 

 more than two hundred years ago, " Nay, the Hoynl Society have found aud published lately that there be thirty and three 

 kimls of spiders ; and yet all, for aupht I know, jjo under that one general name of spider."
