Male genitalia (Text-fig. 201). Uncus composed of two small lobes (" cheeks " of Bethune 

 Baker) fused to the margin of the tegumen ; subunci long, bent about one-third from origin, 

 tapering gradually to the apex which bears a wide-open claw, tegumen fairly large, the posterior 

 edge with a rounded depression so deep that it leaves only a narrow median strip ; vinculum 

 narrow in the sternite ; lower fultura Y-shaped and bearing an anellus which sheathes the penis ; 

 valves elongate oval at the base, narrow in the middle, the upper part deeply notched just 

 before the crescentic apex, whose lower edge is slightly serrate ; penis elongate, the internal 

 portion subcylindrical, the external portion dilated at the apex ; vesica with numerous fine 

 cornuti, uncus bearing long, fine hair, valves with stiffer hair especially on the lower edge in the 

 basal half. 



The male genitalia of all the Euchrysops are like those of E. cnejus, and most of 

 them have been figured by Bethune Baker (1923). They differ little from those of 

 Lepidochrysops, and I find difficulty in defining the limits of these two genera. On 

 the other hand they are far removed from strabo Fabricius, type-species of the genus 

 Catochrysops Boisduval, in which Fruhstorfer (1924 in Seitz, Macrolep. 9 : 921) 

 surprisingly included species belonging to two other quite different genera, namely 

 cnejus (Euchrysops) and p and av a (Chilades). 



In the following list it will be noticed that two species are included, on account of 

 the structure of their male genitalia, which are commonly included in genera only 

 remotely related to Euchrysops. These are unigemmata Butler, described as a 

 Zizera but transferred later by Butler to Chilades, and crawshayi Butler described as 

 a Scolitantides, but placed by Aurivillius in Harpendyreus.
