Burma, Tenasserim and the Malayan Subregion. The Tenasserim speci- 

 mens are dark and often without the white subcostal spot on the fore- 

 wing, approximating thus to the Southern Indian and Ceylon E. taprobana 

 according to Bingham. The food-plant is nearly certainly Tragia cannabina, 

 L., though it is nowhere recorded as far as is known. 



73. Ergolis taprobana, Moore. — This differs as follows from the last : — 

 Wet-season form. — Male upperside with the ground-colour dark ferruginous ; 

 white subcostal spot on forewing rarely present ; the transverse lines black, 

 more clearly defined ; the anterior half of the hindwing as in E. merione 

 smooth, uniform, unmarked. Underside : with the ground colour darker than 

 in merione, the markings on the anterior half of the forewing and in the 

 centre of the hindwing obscured by a superposed, very dark chestnut 

 shading ; on the forewing this dark shading does not extend to the base, 

 apex or termen ; on the hindwing it does not extend quite to the costa. 

 Sex-mark as in merione. Female similar to the female of merione but differs 

 as follows : — upperside : the ground-colour lighter ferruginous than in the 

 male ; the transverse lines and markings very distinctly defined ; the two 

 postdiscal lines formed into more or less broad cordate marks in the 

 interspaces. Underside : ground colour darker than in merione female, 

 sometimes a sort of purplish brown ; the chestnut transverse bands well 

 defined and continuous on both fore and hindwings. 



Dry -season form. — Male and female similar to the wet-season form but 

 the ground-colour paler. Exp. 49 — 56 mm. 



Larva. — The caterpillar is exactly the same as that of E. ariadne in shape 

 of body, arrangements of the spines, their shape and size and the shape of 

 head. Surface of body covered with transverse rows of minute yellow 

 tubercles, each bearing a little seta. Spiracles rather large, oval, the 

 colour of the body, bordered thinly with black. The colour of the body is 

 o-reen with a broad, subdorsal, yellow stripe flanked by a double, interrup- 

 ted, yellow line; segments 7 and 11 suffused dorsally with dark-brown; 

 bases of subdorsal spines of segment 4 brown ; belly light green ; the spines 

 all blue-green and shiny. L; 27 mm.; B: 4 mm. without spines; L of 

 head-horns : 5 mm. 



Pupa. — The pupa is similar to that of E. ariadne in shape and size. It 

 can be separated from that species by the outer margins of the wings being 

 straight instead of slightly waved as it is in ariadne. Surface very slightly 

 shiny, smooth. Spiracular stigmata of segment 2 hardly accentuated ; 

 other spiracles oval, not small, colour of the body. The colour is generally 

 light green, veined densely on wings with brown ; head points, carination of I 

 thorax, lateral wing outlines also brown ; Suspensory hooklets bright golden- 

 brown. L : 18 mm. ; B : 6 mm. at segment 7 ; 5 -25 mm. at shoulders ; 2 mm. 

 between head points ; H : 5 mm. at thorax ; 6 mm. at segment 6. 



Habits. — The habits of oviposition are similar to those of E.
