172 EDW. JACOBSON, BIOLOGICAL NOTES ON THE HETEROCERA. 
The neck of the retort is not closed, but only loosely — 
obstructed by a few silken threads covered with excrements. 
The elastic sides of the opening prevent any enemy pene- 
trating from the outside; from the inside, however, it affords 
an easy exit to the moth after hatching. 
From one of the cocoons I reared an /chneumonid. 
In the Cat. Lep. Phal. Br. Mus. Vol. X. p. 38. Sir HAMPSON 
gives the following synonymy of Zublemma versicolor WALKER: 
Autoba versicolora \NLK. Journ. Lin. Soc. Zool. VII. p. 58. 
1864. 
Thalpochares rubricosa SNELL. Tijdsch. v. Ent. XXIII. p.

Mestleta angulifera Moore. Lep. Atk. p. 179. (1882); id. 
Lep. Ceyl. II. p. 208. pl. 175. ff. 2. 24.; HAMPSON, Moths 
nd 0.343. 
The best coloured figure is given by SNELLEN (I. c.) after 
a specimen from Balangnipa (Celebes). A less satisfac- 
tory one is to be found in MOORE, Lep. Ceyl. III, where 
also the caterpillar, pupa, and cocoon is represented. The 
latter, however, evidently has been drawn after an old, 
shrivelled up example, which did not show the retort-like 
shape. 
The accompanying Plate 5 fig. 5 shows the moth, fig. 6 
the retort-shaped cocoon, and fig. 7 the latter cut open and 
revealing the pupa lying inside.
