108 MESSES. H. J. BLWBS AND JAMES EDWAEDS : 



wing which lies below vein lb. Mr. de Niceville (Jouv. Bomb. Nat. Hist. Soc. 1892, 

 p. 351) speaks of the anal angle (tornus) being fringed with long stout setse ; this is 

 misleading, as the hairs forming the tuft and fringe are not more bristle-like than 

 those which form the tibial pencil in many species of Hesperiidae. These observations 

 are, in part, based on an examination of a male specimen of C. pennicillatum, de Nic4v., 

 ex coll. E. Swinhoe. 



Crossiuea pennicillatum. 

 Crossiura penmcillatum, de Niceville, t. c. p. 351, pi. J. fig. 1 cJ, 2 2- 

 Ilab. Khasia Hills, where it seems rare or very local. 



ACHALAEUS. 



Achalarus, Scudder, Syst. Rev. Am. Butt. p. 50 (1872); Watson, P. Z. S. 1893, p. 33. Type 



lycidas, Sin. Abb. 

 Lobocla, Moore, Jour. As. Soc. Beng. 1884., p. 51. Type liliana, Atkinson. 



Vein 5 in the hind wing is obsolete in lycidas and most of the American species, 

 but well-developed in liliana and all the Eastern species, as well as some of the 

 American. 



The species known to us we distinguish as follows : — 



1 (2). Fore wing above : white discal band reaching vein 1 a, white 



spot in cell 3 filling up the base of that cell liliana, Atkinson. 



2 (1). Fore wing above : white discal band not reaching vein 1 a, white 



spot in cell 3 usually not filling up the base of that cell. 



3 (6). Fore wing above: white spot in cell 3 contiguous to that in 



cell 2. 



4 (5). Clothing of second joint of palpi grey. Hind wing below : 



terminal grey band irregular, not wide enough to reach 



the narrow subterminal pale band bifasciatus, Brem. & Grey. 



5 (4). Clothing of second joint of palpi blackish. Terminal grey 



band on hind wing below suffused, broad, regular, reaching 



about half the length of cell 3 simplex, Leech. 



6(3). Fore wing above: white spot in cell 3 not touching that 



in cell 2. 

 7 (12). Dark spots on the hind wing below very prominent, much 



darker than the ground-colour. 

 8(11). Fore wing below: hyaline spot in cell u not touching that 



in cell 6. 

 9 (10). Hind wing below : subterminal dark spot across cells 16 and 



2 as wide where it is cut sliort by vein 3 as where it is 



crossed by vein 2, the pale border of its inner edge 



straight, that of its outer edge sinuate, receding from the 



termen as it approaches vein 3 proximus. Leech.
