(o xer=}, ) 
of ornamenting its cocoon, which deserves fuller treatment. 
Such will be given shortly in a separate paper.” 
Finally in 1907 Busck stated of Marmara opuntiella, Busck 
(in “ Ent. Soc. Wash.,” viii, p. 97)— 
‘At the last larval molt it assumes the cylindrical form 
with normal legs and spins the characteristic cocoon with the 
peculiar globular ornamentations as do the other species of 
the genus.” 
Tue Arracks oF Tacuinip Fiies upon THE AFRICAN Dan- 
AINE Genus AmauRis.—Prof. Poutton exhibited 5 specimens 
of Amauris psyttalea, Plotz, being all that Mr. W. A. Lamborn 
“obtained from 25 pupae, the rest being parasitized by Tachi- 
nidae” (Oct. 3rd, 1911). All 5 butterflies had emerged Sept. 
20th, 1911. Seventeen dead pupae from the same company, 
12 of the Tachinid flies, and a number of their puparia were 
also exhibited. Mr. E. E. Austen had recognized 2 species of 
Sturmia in 4 of the flies submitted to him. In the same 
letter Mr. Lamborn spoke of another company of A. psyttalea 
in which “every single pupa was parasitized in this way.” 
Prof. Poulton pointed out the bearing of these and Mr. 
Guy Marshall’s earlier observations on the extraordinary 
assumption of the late Hrich Haase, that the specially pro- 
tected species of Lepidoptera are immune from the attacks of 
parasites. 
Some ANT-TENDED LycAENID LarvVAE OBSERVED BY Mr. W. A. 
LaMBoRN IN THE Lacos District.—Prof. Poutron exhibited 
material illustrating the following records received in letters 
from Mr. Lamborn— 
1.—WMyrina silenus, F. 
March 3rd, 1911. 
“The food-plant, which bears a fruit much like a little fig, 
grows here and there in the primitive forest round Oni camp. 
The larva of Zuchromia lethe, F., also feeds upon it, as well as 
that of a Sphingid moth. The larvae are green with white 
tubercles and are not very conspicuous on the food-plant, 
though found in all positions on it, on both sides of the leaves 
and frequently on growing buds at the end of stems. They 
pupate anywhere ; frequently on the upper side of a leaf. It
