MYRMECOPHILOTTS INSECTS.

solid earth left between the galleries of a much larger kind of ant ; or 
two kinds of ants may share a nest. Wassmann records no instances 
from this country but our common ant Myrmecocystus setipes certainly 
allows another ant to build between its galleries, and there are probably 
other instances. Ants are also termitophilous in that they live in 
termites’ nests. Two sphegid wasps, Rhinopsis constancice, and R. rufi- 
cornis, Cam., mimic and live where Sima rufonigra is common ; but the 
exact relations are doubtful. Elsewhere, Fossorial wasps prey upon 
ants, carrying them off to stock their cells with. Various Parasitic 
Hymenoptera destroy ants but none are yet recorded in India. Lepi- 
doptera include a very few whose larvae live in ants’ nests (none Indian), 
and a number which are visited by ants, which have special “ honey 
organs 11 and which in some cases pupate in the ants’ nests. 
deNiceville remarks that some of these caterpillars will thrive only in 
association with their particular ants. These are all Lyccenidce ; the list

Among Diptera, there are less than 20 species recorded, chiefly 
European, Microdon being the best known. A single Indian example 
among Heteropterous Rhynchota is the Coreid Dulichius inflatus, Kby., 
which Wroughton found to mimic Polyrhachis spiniger, Mayr., and to live 
where this ant is common. Of the Homoptera, there are species of 
Fulgoridce and Membracidce which are visited by ants to get the sweet 
secretion. Our common species of Leptocentrus among the latter and 
Pyrilla aberrans, Wlk., among the former are examples. Psyllidce, 
Aphidce and Coccidce also afford many examples, ants either simply 
visiting them to get honeydew, or building shelters over them, or 
maintaining them in their nests. (Ecophylla smaragdina commonly 
sews together the leaves round colonies of Coccids and makes shelters 
for them ; a very large number of our Coccids and Aphids are visited 
by species of Camponotus, Cremastog aster, Cataulacus, etc., though we
