Type locality. — Engano Island, Barussan Islands, western Su- 

 matra. 



Geographic distribution. — Engano Island, western Sumatra. 



Bemorks. — This island race is decidedly smaller than Sauropatis 

 chloris chloins, Sauropatis cTiloris cyanescens^ Sauropatis chloris 

 collaris, and Sauropatis chloris chloroptera; ^ and, curiously enough, 

 like forms of so man}^ other species from the islands off the western 

 coast of Sumatra most closely resembles the race indigenous to the 

 Andaman Islands — another case, apparently, of parallel develop- 

 ment. It may be distinguished from Sauropatis chloris cyanescen^s 

 by its much smaller size; in the male by darker, more greenish (less 

 bluish) upper parts, with thus more contrast between back and 

 wings; and, in the female, by darker, more olive brownish upper 

 surface. From Sauropatis chlo7%s armstrongi it may, in the male, be 

 separated by its darker, more brownish and greenish upper parts; 

 usually more greenish wings; more blackish ear-coverts; more con- 

 spicuous blackish nuchal band; and less pronounced buffy suffusion 

 on the sides and flanks ; and, in the female, by darker, somewhat more 

 olivaceous upper surface; more greenish (less bluish) wings; wider 

 blackish nuchal band; and ordinarily more blackish auriculars. The 

 female of Sauropatis chloris azela differs from the male in much 

 darker, duller, more brownish upper parts, more greenish wings, and 

 lack of any buff on sides and flanks.
