346 Mr. C. O. iene Five Years’ Observations 
tection, the Hewitsonias, Teratoneuras, ete., have of 
course quite visible heads. I use the w ord “ eremobiotic * 
to express this insect counterpart of the desert “ xero- 
phytic” plant. Synoekete implies a more intimate rela- 
tion, more applicable, is it not, to guests (welcome or not) 
living inside the nests? Perhaps eremosymbiont, if that 
is a “legitimate coimage, fairly nearly expresses the idea. 
Wasmann, according to Wheeler, uses the term trophobiosis 
to describe the more common relation of the Lycaenine 
Lycaenids. In a “ trophic” classification of Lycaenidae 
the two terms contrast fairly naturally. They cannot be 
ranked with the scafferying * neutral synoeketes, and I’m 
sure to most insects the “ playing field,” of a Cremastogaster 
colony especially, is a veritable desert. In case such a 
term were too particular, implying absolute proof rather 
than the more or less hypothetical, atrophic and syntrophic 
symbiosis is perhaps a better general description. 
The Pupation of Teratoneura. 
March 1, 1917.—The larva pupates either on a leaf or 
on a slender dead twig or dead herbaceous stem on the 
tree or round its base. The trees on which they are 
found throw out numerous very slender aerial roots, which 
hang, down from the stem and_ branches. These are 
favourite pupation places. When these end in the air and 
not, as they sometimes do, become re-attached to the 
parent tree lower down, ants do not generally run down 
them. Such a place would be relatively safe at the critical, 
vulnerable period of transition. Argiolaus pupae are 
generally to be found on shrubs or herbs at a little dis- 
tance from the ant-tree, and when, as happens at times, 
they pupate on a plant too near the tree, the pupae are 
frequently devoured by the ants which respected them or 
even protected them as larvae. But the Teratoneura 
almost as frequently as not pupates on a leaf with the 
base of its stalk within an inch of Coccids and ants. 
. Teratoneura Pupae heavily parasitised by Chaleids. 
Feb. 22, 1917.—I notice that the pupae are heavily 
parasitised by Chalcids, and I cannot say I have ever 
seen a parasitised Hewitsonia of a good many seen by 
me now. 
March 1, 1917.—I think I remarked on the frequency 
with which this species is parasitised, a very tiny Chalcid 
* “ Scaffery ’ is defined in Murray’s Oxford Dictionary as— 
“ Extortion, extortionate taking of perquisites.”
