 7. Genus — Chiladbs. 



There are only two species belonging to this genus and they are both 

 fairly widely distributed, laius over the whole of India. Ceylou and Burma, 

 trocliilus inhabiting the same places with Europe, Africa, Asia Minor, Per- 

 sia to the west in addition as well as the Maiayau sub-region and Austra- 

 lia ; the former also extends into China. The former is more of a jungle 

 insect, the latter is found in the driest regions ; the transformations of 

 both are known and will be found below ; the lar\ le of both are attended by 

 ants ; that of lams feeds upon Limes, of the other upon Lotus corniculatus. 

 Colonel Bingham says that the genus is "vtry closely allied to Lyccena, 

 from which the two forms that are placed under it are kept separate, 

 more for convenience and because of the character of the wing-markings on 

 the underside and the peculiar range of the forms, than for the slight 

 structural difference of veins 3 and 4 of the hindwing being both emitted 

 from the lowsr apex of cell." 



142. Chiiades trochilus, Freyer.— Male Upperside: brown, somewhat variable 

 in tint. Specimens from dry localities are much paler than those taken in 

 areas with a comparatively heavy rainfall. Fore wing : uniform, with a 

 very ill-defined anticiliary dark line in some specimens. Hind wings: a sub- 

 terminal series of round black spots crowned with pale ochraceous, orange 

 or even, rarely white ; the posterior four spots generally well defined and 

 outwardly edged witii white ; the anterior spots obsolescent and without 

 the interior edging of yellow or the outer edging of white ; a well marked 

 slender anticiliary black lino. Cilia white, basal halves brown. Underside 

 pale silky brown. Fore wing : with the following white markings : — a short 

 line on the inner and outer sides of the discocellulars ; a transverse, 

 slightly curved, discal series of small, sometimes more or less incomplete 

 rings ; a transverse, postdiscal series of disconnected slender lunules ; a 

 sub-terminal series of similar but more regular lunules and a terminal broken 

 line, followed by a dark unbroken anticiliary line ; the ground-colour 

 between the two short discocellular lines, that enclosed within each ring of 

 the discal markings, and between the subterminal lunules and the terminal 

 line slightly darker than on the rest of the wing ; sometimes nearly black 

 between the upper three or four pairs of discal lunules. Hindwing: two 

 short white lines on the discocellulars ; the discal, postdiscal and terminal 

 markings as on the fore wing, except that enclosed between the subtermi- 

 nal series of white lunules and the terminal white line is a complete series 

 of dark spots, the posterior three or four jet-black sprinkled outwardly 

 with metallic-green scales and encircled with pale ochraceous. In addition 

 there are a transverse subbasal series of four white-encircled black spots 

 and a similar subcostal spot in middle of interspace 7. Antennae, head, 

 thorax and abdomen brown, the shaft of the antenniTC speckled with white
