8. PAPILIO INDRA Reak 

 Indra Swallow-tail 



Size, small, Avith the tails extremely short, }^ ig. (J, d. The black pre- 

 dominates and the general pattern of coloration is similar to that of P. 

 asterias, but the inner band of yellow spots is more extended, these 

 greatly exceeding the outer in width ; on the hind wings are continu- 

 ous or interrupted only by the narrow veinings ; on the other hand, the 

 blue spotting between the two bands is confined to the hind wings, and 

 is much restricted even here. The orange spot is large, surrounding 

 an oval center. There is an additional dot of yellow in the central cell 

 of the fore wing, and a black dot in the second of the yellow spots of the 

 inner band on the fore wings, near the upper margin. Beneath, the 

 markings are repeated but, unlike asterias, only the upper and lower 

 spots of the outer band of crescents are orange, and there are only slight 

 traces of it on the outer portion of the inner band. The spottings on 

 the sides of the abdomen are absent or are represented by a dot at the 

 extremity. Expands o.(K).
