of the Butterfly -genus Prothoe. 53 



in the ' Genera of Diurnal Lepidoptera/ a very fair figure of 

 the female. 



In the museum collection there are four examples of the 

 Javan species, two males and two females, collected bj Dr. 

 Horsfield ; a fifth specimen, without localitj-label, staads in 

 the Hewitson collection as the female of an allied species, 

 although it is in fact a male. 



In 1854 the museum purchased a specimen of a Prothoe in 

 a mixed collection of insects from various localities, but bearing 

 no definite indication as to whence it came ; it is likely enough 

 to be the missing Malacca form which Mr. Distant quotes on 

 the authority of Wallace. This local form or species stood 

 in the museum for many years as the supposed ms^Q oi Prothoe 

 Franchii ; and consequently when, in 1867, and again in 

 1882, we received specimens of a third species from Borneo 

 and Tenasserim, I for the time believed them to represent an 

 interesting variety of the male approaching the female in 

 coloration ; in the Hewitson collection are three examples of 

 the same form, evidently regarded by him as males of P. 

 Franchii (though the first in the series is a female). 



In a collection received in 1880 from Dr. George Watt 

 and made by him in Manipur, was a male specimen of a 

 fourth species perfectly distinct froni the three previously 

 received ; this species will be described in full in a paper 

 giving an account of Dr. Watt's collection. 



The four species may be separated as follows : — 



a. Primaries above with the oblique belt moderately 

 broad (more so in the male than the female), cobalt-blue, 

 intersected by a broad white band ; apical area of secon- 

 daries purplish brown ; prevalent colouring on external area 



of secondaries below grey P. Franckii. 



b. Oblique belt of primaries shining aziu-e or greenish, 

 ■with a series of irregular white dashes to represent the 

 central belt ; apical area of secondaries purplish black ; 

 prevalent colouring on external area of secondaries below 



pale green _...._ P. angelica. 



c. Oblique belt of primaries without white band or 

 spots, excepting upon the costal border ; apical area and 

 external border of secondaries chocolate-brown. 



c. ] . Oblique belt moderately broad, greenish blue ; secon- 

 daries elongated, as in P. Franckii, with well-marked caudal 

 a,ppendage, apical markings white with bluish borders ; pre- 

 valent colouring on external area of secondaries pinky 

 greyish P. uiiiformis. 



c. 2. Oblique belt very broad, covering nearly half the 

 wing, three spots of the same colour at centre of external 

 border, only separated from the belt by a blackish submar- 

 ginal stripe ; secondaries decidedly shorter and less caudate, 

 apical markings blue ; prevalent colouring on external area 

 greyish olivaceous, black and green P. vegalis.
