102 LEPIDOPTERA INDICA. 



Adult Caterpillar. — Cylindrical ; with four pairs of long flesliy subdorsal 

 filaments, which have pink bases and black tips, three pairs being on the anterior 

 segments and the fourth pair on the 12th segment. Body pinkish-white, with 

 lateral yellowish blotches, the segments each divided by a black line and anteriorly 

 bordered by a transverse narrow pink band and purple-brown stripes ; spiracles 

 black ; head with a dark red stripe in front and on each side ; forelegs black ; 

 middle and hind legs black, ringed with pink. (Java form, T. Claudia.) 



Chrysalis. — Short, thick across the middle, thorax concave behind, abdominal 

 segments dorsally convex; metallic golden-brown with darker brown anterior 

 stripes. 



Habitat. — N. W. and E. Himalayas; Assam; Khasia and Naga Hills; Cachar ; 

 Upper and Lower Burma. Nicobars. 



Histoeical Note. — The true P. Midamus of Linnaeus has been shown (see 

 "Monograph of the Euploeinse" published in Proc. Zool. Society of London, 1883, 

 p. 312) to be a species of the genus Isamia, and pertaining to quite a different section 

 in this group of butterflies — which is characterized by the possession of a sexual mark 

 on the forewing and a large patch on the hindwing. Linnseus had erroneously con- 

 founded these two distinct forms [Trepsichrois and Isamia] and, in his original 

 description (Syst. Nat. 1758, p. 470) cited Ehret's plate iii. as well as that of his 

 plate xi., and De Geer's figure in Acta Holmiee, 1748, pi. 6, f. 1, 2, as illustrations, 

 and (subsequently) supplementing his description in the " Mus. Ulr." p. 251, with that 

 of our present insect. Ehret's plate iii., however, represents a male of our present 

 species (P. Linnai), and his plate xi. a male, and De Geer's plate the female, of the 

 true Midamus. Linnseus's description also agrees with these two latter figures, giving 

 therefore all that was necessary for fixing the identity of his species. Subsequent 

 authors, however, when referring to the Linntean species Midamus, applied the name 

 to the present and well-known common Indian insect (T. Linncei), instead of to the 



Chinese insect unmistakably represented on Ehret's plate xi. and on De Geer's plate 6. 



The distinctive characters of the Linngean Midamus are very correctly given by Dr. 



Zinken-Sommer, Nova Acta Acad. Nat. Cur, 1831, p. 190, in his remarks upon the 



Euploea Pavettce. 



Metamoephoses of Teepsichkois. — We know only those of the Java form, T. 



Claudia, the larva of which was discovered by the late Dr. Horsfield, " feeding on a 



species of Ficus," and from whose drawings our description and figures are taken. 



In Semper's "Eeisen Archipel. Philippen," plate A, fig. 3, 3a, the larva and pupa of 



the allied T. Diocletia, are also figured. 



Distribution within Indian Area. — The range of T. Linnoii extends from the 



North West, through the Himalayas to Burma. According to Col. Lang (P. Z. S. 



1865, 494) it appears to be rare in the N. W. Himalayas, a single specimen only 



being obtained in a valley of the Simla district. Mr. A. G. Young also obtained only
