128 IlIfOPALOCERA MALAYANA. 



The following species is included here with some douht. A male specimen, which is 

 figured, and considered as collected in the Malay Peninsula, is the only authority I have for 

 its presence in this fauna. Further and corroborative information is therefore desiderated. 



Euthalia lubentina. (Tah. XIV., fig. 4 ^ .)

Male. Closely resembling the male E. ndonia (Tab. XIX., f. 10), but differing in the form of the 

 wings, which are broader, less angularly attenuated, and the anal angle of the posterior wings not 

 elongately produced, as in that species ; on the upper surface the white spot in the cell is absent or 

 only faintly indicated ; beneath the markings are very similar. 



Female. Above with the anterior wings closely resembling those of female E. adonia (Tab. XIX., 

 f. 11); posterior wings, however, without the broad central white fascia of that species, and resembling 

 those of its own male. Beneath the anterior wings are as above, the posterior wings as in male. 



Exp. wings, 3 71 niillim. ; 5 6'2 to 75 millim. 



Hab. — Continental India; Bengal (Moore); near Cachar (coll. Dist.) ; Bombay (Leith — coll. Dist.) — 

 Ceylon (coll. Moore and Brit. IMus.) — Malay Peninsula '? 



The larva and pupa of this species, from drawings made by Mr. A. Grote, are figured by 

 Horstield and Moore,* and from drawings of the Bros, de Alwis in Moore's Lepidoptera of 

 Ceylon. According to Mr. Grote the larva feeds upon " Loranthus."t 



Genus TANAECIA. 



Tanahia, Butler, Proc. Zool. Soo. 18G8, p. 610. 



In general form and neuration this genus resembles Euiludia, differing chiefly in the following 

 characters : — the middle disco-cellular nervule of the anterior wing is only moderately recurved ; the first 

 subcostal nervule of the posterior wings is emitted at a greater distance from the base of the subcostal 

 norvure than in EiitlmUn, and the second subcostal has its origin a little beyond. The palpi have a slender 

 bristle-Hke terminal joint varying in different species. 



This genus is much smaller in extent than EutlmUa, and likewise has a different 

 distribution, for whereas that genus may be said to possess its head-quarters in North-Eastern 

 India, Tanaecia is almost confined to the Indo-Malayan region, and is apparently absent from 

 Continental India and Ceylon, though found in the Andaman Islands. 



It is extremely difficult in this genus — particularly in that portion of it which is found in 

 the Malay Peninsula —to decide in several cases, and from cabinet specimens or figures alone, 

 whether the term " species " or " variety" should be more correctly used. I have therefore, in 

 some cases, kept tlu; distinct forms in specific isolation, leaving the ultimate decision to the
