Lucas described tlii.s Philippine insect in 1835 under the name of " rhada- 

 manius Boisd." ; as Boisduval's Sjxc. Gen. Li'p. I. came out after Lucas's Lcp. Exot.. 

 Lucas has the priority, and the name of 'rhadamantus must be spelt without an h 

 behind the t. Lucas gives Boisduval as author ; from this I conclude that he I'eceived 

 the name of the insect from 15oisdu\al in litt. 



Boisduval's " rhadfi.inanihu^s" of Spec. (jru. Le.p. is a composite species; he 

 describes first the Philippine 'iii(de, then the female of the Indo-Chinese representative 

 species, and thirdly, as var. A, the proper female to his Philippine male. As most 

 authors did not perceive that Boisduval's description of the male applies to the 

 Philippine, not to the Indo-Chinese species, and recognised the " var, A " as the 

 Philippine female, they erroneously used the name of " rhadamantltus Boisd." for 

 the Indo-Chinese PapiUonid, not for the Philippine one. Gray was the first to make 

 this muddle ; he bestowed a new name upon the Philippine species, and called the 

 Indo-Chinese insect " rhadamanthiw Boisd.," and nearly all the authors writing upon 

 the Indian fauna follow him. 



Lucas calls the species " aniphrisius " on the plate (not in the text), but corrects 

 this misprint in a note on page 5. In Kirby's . Catalogue " amphnsiua Lucas" 

 is said to be from North India; Staudinger & Schatz in Exot. Schmett. I. p. 4 

 (1884), and Fickert in Zool. .fahrbuch. p. 734 (1889), uncritically accept this mistake, 

 so that now in most German collections the Indian species stands as " var. amphrisius 

 Lucas," the Philippine insect as " rhadamanthus Boisd.," while in England the first 

 is known as "rhadamanthus Boisd." and the second as " nephereua Gray." The 

 proper nomenclature is as follows : — 



(1) T. rhadamantus (Lncaus) : Philippines; 



(2) T. aeacics (Felder) : India, JIalacca, Siani, China.

S. The anal region of the hindwings is strongly produced and pointed; the 

 branches of the median nervure stand rather closer together than in the other species 

 of Troides ; the basal portion of the median vein is very long, more than half as long 

 again as the corresponding part of the subcostal nervure. The median cellules of the 

 hindwings above are sometimes (chiefly in Mindoro specimens) shaded with a rather 

 dense black scaling, wliich occupies, besides the median cellules, often also part of the 

 discoidal cell. 



The adnervular streaks of the forewings are alwaj's whitish and very narrow ; 

 below there is sometimes a feeble spot at the sulnnedian nervure wliich assumes 

 a yellowish colour. 



The abdomen is entirelv Iilack above, the segments not lieing edged witli yellow, 

 as in the Indian alh'ed species.
