Larva. " Long, cylindrical and smooth with an oily gloss. Two 

 subdorsal rows of long white bristles springing from minute white 

 tubercles ; head, sides and back sparsely clothed with short white 

 bristles: colour brown, head and feet black. It may be found from 

 the beginning of August everywhere on the common ' mistletoe ' 

 (Loranthus), from which it will drop and hang by a thread if the 

 tree is shaken. We have never found it feeding on anything 

 else. Unlike most butterflies this species lays as many as twenty 

 or thirty eggs on one leaf, in parallel rows, with equal intervals, 

 and the larvae continue in some measure gregarious to the last, so 

 that a large number of pupae are often found, at a little, distance 

 from each other, on a wall, or the trunk of a tree." 



Pupa'. " Closely attached by the tail and by a band generally 

 to a vertical surface with the head upwards. It is moderately 

 stout with a short snout, two small tubercles on the head, a sharp 

 but not prominent dorsal ridge on the thorax, continued in a row 

 of tubercles on the abdominal segments. Below these are two 

 partial subdorsal rows. Colour bright yellow ; tubercles and a row 

 of spots denning the wing-cases black. 



" Large numbers are destroyed by a dipterous parasite very like 

 a common house-fly." (Davidson $ Aitlcen.)

cJ $ . Closely resembles D. eucharis but can be distinguished as 

 follows : 6 . Upperside, fore wing : the black margins to the veins 

 more diffuse ; the transverse postdiscal fascia diffuse, ill- defined, 

 oblique, not parallel to termen in its lower portion but terminated 

 at apex of vein 2 ; the apical portion of the wing beyond the 

 fascia more or less so thickly shaded with black scales as to leave 

 the white lanceolate spaces between the veins (so prominent in 

 eucharis) ill-defined and obscure. Hind wing white, the black 

 venation and terminal narrow black border as well as the sub- 

 terminal vermilion-red spots between the veins on the underside 

 show through by transparency. Underside : fore wing as in 

 eucharis, but the black margins to the veins much broader and the
