The male genitalia of N. lamprocles scarcely differ from those of lyzanins except in 

 the shape of the tip of the valves. In kalinzu the subunci are short and robust and 

 the saccus robust and triangular. In quadricaudata the subunci are long and slender 

 as in lyzanius, but the saccus is disproportionately long, the valves digitate, almost 

 filiform, and the penis extremely long and thin. N. quadricaudata was described as 

 a Triclema, but the presence of vein 8 in the fore wing places it in Neurypexina, 

 which is only to be distinguished from Anthene by the fore wing venation. 



The larva of TV. lyzanius has been described by Lamborn, 1913, Trans, ent. Soc. 

 Lond. 1913 : 484. It lives in company with the ant Pheidole rotundata.

Genus NEURELLIPES Bethune Baker 



Neurellipes Bethune Baker, 1910, Trans, ent. Soc. Lond. 1910 : 66. Type-species : Lycaenesthes 



lusones Hewitson, by original designation. 

 Lycaenesthes Moore, 1866 (partim) ; Aurivillius, 1898 : 352 ; 1924 : 455. 

 Monile Ungemach, 1932. Type-species : Monile pluricauda Ungemach (gemmifera Neave, 



1910). 



Eyes densely pilose, palpi extending well beyond the frons, second segment laterally com- 

 pressed, clothed above with scales and below with stiff hair, third segment fairly long, 

 acuminate ; antennae like those of Anthene ; <J fore leg tibia shorter than femur, tarsus un- 

 segmented, finely spinose below ; mid and hind legs, femora clothed with long hair, tibiae 

 shorter than the femora and bearing two robust spurs, metatarsi very long. 



Wing shape. Like that of Anthene. 



Wing venation (Text-fig. 320). Fore wing with 10 veins, veins 8 and 9 absent, 10 and n free. 



Male genitalia (Text-fig. 169) (see also Bethune Baker, I.e. pi. 13, figs 35—36). Uncus com- 

 posed of two oval lobes narrowly fused to the tegumen on either side of the median indentation, 

 subunci with very robust bases, tapered, and bent at about one-third, posterior margin of 

 tegumen deeply excised, vinculum fairly wide, with a long saccus ; lower fultura (furca) with a 

 pyramidal base and long slender arms ; valves wide with finely serrated distal edges, then 

 deeply excised, the upper process ending in a sharp point, the lower process in a strong tooth, 

 penis elongate, the upper surface of the internal portion widely open, the external portion evenly 

 tapered and ending in a trumpet-shaped apex, uncus and apices of valve pilose. 



The male genitalia of N. chryseostictus and 2V. fulvus are of the same type as those 

 of 2V. lusones, that is to say their valves are quadrangular, and even expanded
