! 1 Orthoph(etus phan^us. 



Eudamus phanaus, Hewitson, Descr. Hesp. p. 14 (1867). 



Casyapa phaneeus, Distant, B-hop. Mai. p. 386, pi. xxxv. fig. 18 (1886) ; Watson, Hesp. Ind. p. 109 

 (1891). 



In point of colour Distant's figure represents 0. lalita rather than 0. phanmus, but 

 the Perak specimens in my coll. agree with the Bornean type.

! OUTHOPHOETUS LALITA. 



Erionota ? lalita, Doherty, Jour. As. Soc. Beng. 1886, p. 363.

Until Mr. Edwards separated this from the Bornean species by the costal fold, Elwes 

 had confused it with 0. phaneeus. It is, as he pointed out, much yellower in colour, 

 but has similar markings. It has only been taken, so far as we know, by Doherty 

 in the Chittagong and Karen hills.

The type in the British Museum remains unique ; but as Dr. Lidderdale's collection 

 was made at Buxa in Bhutan and Darjeeling it is almost certainly from one of those 

 localities, probably the former. We append further particulars of this specimen, 

 supplementary to the original description cited above.
