<J?. Tonth abiloniiiial tergite (PI. XXVI. f. lit) resembling in a dorsal view 

 that of Ilcrsc coin-olnili, slemlerer in a l:iti>ral view, gradually narrowed to a point. 

 (.'lasi>ci- sole-sbai)ed, rounded-dilated dorsally before end, ventral margin obliciue ; 

 liariio (I'l. XXXV. f. cS) with a broadly sickle-sbaped distal process, which points 

 dorsad, and is armed at tlic rounded vontro-distal edge with long suberect teeth, 

 the most jiroximal tooth broad ; spines of clasper near harpe longer than in the 

 species uf IJi'rsn. Penis-sheath unarmed externally, as broad as in Herse. Vaginal 

 plate see above. 



The s]iecinicn recorded by Pagenstcchcr from Palum {Dalil, 3. i. '97) is in the 

 Berlin INluseuni, where we have examined it. It is ol/liqiia, Pagenstechcr himself 

 says, I.e., that the individuals recorded by him as discistriffa correspond to the 

 obliipia and (liscistriya forms. Following Hamjjson, unfortunately too closely, 

 he gives as synonyms of i/iscistiiffa^which should stand as menephron — three 

 distinct species ; the four species thus treated as one belong, in fact, to three 

 genera. 



There is no species with which ohliqiia could be confounded, if one compares 

 the palpi, or the size of the thorax, or the pattern of the body and wings. 



The insect is apparently rare, but has a wide range. 



Huh. Ceylon, N. India to the Bismarck Archipelago, probably in all the Indo- 

 Malayan and the Papuan countries, but so far found only — to onr knowledge — in

As Manduca of Hiibner is a nanu' without definition, it is not a scientific term^ 

 and cannot sujiersede Ac/ic'rontiii. lliibner liimself employed the name later on 

 not for a genus, but lor a whole "stir|is."
