THE GENUS " AMBLYPODIA " AUCTQ^0I J (DE NICE- 

 VILLE, MOORE, SWINHOE, ETC.), NEC HORSFIELD 

 (LEP. RHOP.). FEB 1 i ;.., 



By N. D. Riley, F.E.S., F^&>. 



The generic name Amblypodia was proposed by "Horsfield 

 (' Cat. Lep.,' E.I.C., p. 98, 1829) for a large number of Bpecies of 

 Lycsenidse, divided into five sections, viz. : (1) Narada ,- 

 (2) vivarna ; (3) apidanus, centaurus, helus, eumolphus ; 

 (4) phocides ; (5) vulcanus, lohita, syama and some others. On 

 p. Ill of the same work he states that he considers the species 

 of the third section to be typical of the genus. The type of the 

 genus must therefore be one of the species included in the third 

 section, and Boisduval's action in 1870, specifying narada as the 

 type, cannot be accepted. The type was finally fixed by Scudder 

 in 1875, who specified apidanus as the type. His action was 

 perfectly correct, and must be upheld. Amblypodia must there- 

 fore supersede Arhopala as at present used, and I propose the 

 name Horsfieldia, n.n., to replace the Amblypodia of modern 

 authors, with narada, Horsf., as the type of the genus. 



Since the appearance of Bethune-Baker's excellent ' Monograph 

 of the Amblypodia Group ' little has been done with this rather 

 obscure genus. The life-history of one of the species (H. anita, 

 Hew.) has been admirably described by T. R. Bell in the ' Journal 

 of the Bombay Nat. Hist. Soc.,' xxvi, p. 444, and that of the 

 other (H. narada, Horsf.) less fully by Snellen in ' Rhop. Java, 

 Lyesenidie,' p. 63, 1918 ; and the various races of the species 

 hopelessly confused by Fruhstorfer in a paper in the ' Ent. Zeits.' 

 (Stuttgart), xxi, p. 150, 1907. 



As the latter paper is very misleading and also very little 

 known, the following summary of the species and their named 

 forms would appear to be necessary. 



The genus, so far as is known, is composed of three species, 

 separated as follows : 



Males. 

 a. Upper side fore wing, purple with a narrow even black 



border anita. 



B. Upper side fore. wing, brilliant blue. 



a. Black border narrow on costa and posterior portion 



of hind margin, broad at apex .... narada.
