plant. The Swordgrass (Oladium), if searched now, will 
yield many larve of Hesperide, and also of Tesiphone abeona, 
but, as this plant dries too quickly, and so crushes the larve 
to death, it is better to wait and collect these in the pupal 
stage in September or October, when they can be removed 
from their food plant. They are also nocturnal feeders. 
Many Lycwnide may be found now, such as Candalides 
hyacinthina and the Ogyris —G.A.W. 
Mr. Froaaarr’s Tour.—Members of the Club will, one and 
all, we feel sure, congratulate Mr. Froggatt on his having been 
selected to tour the world on behalf of the majority of the 
Australian States. His duty is to make investigations re Fruit 
Fly and other pests, and, considering his vast knowledge of 
economic eutomology, the result of his enquiries should be of 
much public utility. Mr. Froggatt, who leaves Sydney on the 
8th of July, will be absent a little over a year. 
Nores on Wes-spinnina Ants.—This is the title of an 
interesting paper published in the June number of “The 
Victorian Naturalist,” by Edward Jacobson. In the course of 
his remarks the author questions the correctness of the name 
applied to the Green Tree-Ant of Australia, namely, Wcophylla 
smaragdina, regarding the speciesrather as (H.virescens. The first 
of these two names was applied by Fabricius to the Asiatic form, 
and the latter to the Australian. In support of his contention, 
the writer points out that the females of smaragdina are green, 
the males dark brown, and the workers red, hence the, popular 
name “Red Ant” in English, and ‘‘ Roode Mier” in Dutch, 
' On the other hand, the workers of virescens are of the same 
green. colour as their females, whilst the males are, the author 
believes, black. 
Carerpintars Parasitic on Antrs.—Mr. Edward Jacobson 
records the following interesting observation in “The Vic- 
torian Naturalist” (June) :—‘‘ In December, 1905, I discovered 
at Samarang a small caterpillar, which is a parasite of 
Polyrhachis. It lives in great numbers in the nests of the 
ants. The caterpillars are enclosed in the web of the nest 
(which is woven by the ants with the aid of their larve) in 
curious little cocoons, which they make in the shape of two- 
valved shells. As soon as they can get at the cocoons of the 
ants, they fasten them with some threads, and then devour the 
pupa, after having pierced the cocoon at the bottom. The 
moth which I reared from the caterpillar does not seem to 
have been described yet.”
