tinctly against the green of the rest of the upperside. Ants are 

 very greedy of the exudation from the gland of the caterpillars 

 and, veiy generally, may be found clustering on their "backs in 

 numbers. The species that have been particularly noticed in atten- 

 dance are Camponoius compressiis, Fabr,, a large, black species, 

 inore than half an inch in length ; and Cremastogaster of unde- 

 termined species. It is more than probable there are also others. 

 The butfcerfly is a low-flying insect of fairly rapid movements but 

 it never flies far before settling again. It sits on the uppersides 

 of leaves with its wings closed over, the back and is Constantly 

 fubbing the two hind wings together; it walks about a good deal, 

 also, amongst the flowers and on the leaves and does not seem to 

 visit flowers much for food. It is found everywhere, in the hills 

 and plains, in the jungles and open desert tracts in Northern and 

 Western Africa, Arabia, Persia, Baluchistan, N. W. Himalayas, 

 the Punjab, Western, Central and Southern India, Ceylon. 

 Assam, Upper Burma. It occurs thus in Sind where the annual 

 rainfall is only 2 inches in some parts, and in North Kanara in 

 Bombay where it reaches 300 inches locally. ' • . 



The pictures of the male and female, figures 51 and 51a pri Plate 

 (j, are both too dark in the colour of the blue on the uppersides ; 

 the male should be pale purple to violet, the female should have 

 the blue at the base lighter blue. Both undersides are generally 

 whitish though yellow is not uncommon. 



, 156. Tarucus plinius — This form closely resembles in both sexes on the 

 Tipperside 7'. theojihrastw^, but the character and disposition of the mark- 

 ings on the underside are completely different, but is less blue and browner 

 on the upperside, the disc bare of hairs and the fringe of the inner margin is 

 blye in both sexes. 



Male. (PI. 6., fig. 45). — Upperside : dark brownish-violet with, in certain 

 lights, a rich blue suffusion, and the markings of the undersides (in both 

 wings) showing through by transparency. Fore wing : no discocellular black 

 spot, so conspicuous in T. theophvastun ; terminal margin with a narrow 

 edging of fuscous black, widest at the apex, gradually decreasing to the 

 toruus, followed by an inconspicuous, anteciliary, jet-black line Hind wing : 

 costal margin slightly but broadly shaded with fuscous, which is continued 

 as a slender, anteciliary, black line to the tornus. Underdde ; white. Fore 

 wing: with the following brownish-black markings: — an irregular edging 

 . along the costa to near the apex from which extends down\vards a subbasal 

 band, broadened across the cell and below it ; an irregulai* band that ex- 

 tends along the discocellulars and below them to interspace 1 wheife it ends 

 ia a point ; an upper, discal, curved band of more even width, but dislocated 

 b^low vein 4, the lower portion of it shifted inwards fofms a large, quadrate 

 spot in interspace 3, below vein 3 the band is continued downwards by two 

 small, inconspicuous spots, beyond this is a very shprt, acuttly-pointed, com- 

 ma-shaped mark ; a very regular, evenly curved, complete, transverse lunular 

 line, a transverse series of subterminal spots and ati; anteciliary, slender

 wards from the dorsum is a triangplar marlj, the edging of white colour left
