At the end of each is stored a pellet of honey and pollen, 
on which the larva feeds. The early spring Axdrene often 
assumes the perfect state in the autumn, and sometimes 
make their appearance then, but usually they remain in 
their burrows till the spring. A most interesting little 
parasite of Andren@ is an insect called Stylops melitte, 
though possibly two or more species go by this name. The 
Stylops is sometimes placed, with one or two allied genera, 
in an order by themselves, called the Strepsiptera, from 
the twisted wings of the male. They are now usually re- 
garded as aberrant Coleoptera. Szy/ops is of small size, the 
male being about one-eighth of an inch in length. Its 
wings are milky white. The female Sty/ops is wingless 
and never leaves the body of the bee, where it can often 
be seen protruding between the segments of the abdomen. 
Smith says that if the Bee containing the female Sty/ops 
is kept alive for some days, the whole abdomen of the Bee 
will appear to be covered with a very fine dust. These 
specks of dust are the larve of the S¢y/ofs. When the 
Bee visits a flower, some of these larve are left behind, 
and attaching themselves to other Bees they are carried to 
other cells. From one to four specimens of St#y/ops can 
often be found infesting a single Andrena. 
Coming now to the Cuckoo Bees, which get the name 
from their habit of depositing their eggs in the cells of 
other bees, we first notice those of the genus Womada. 
They are not at all like bees in their general appearance, 
in fact, most people who are not entomologists would call 
them wasps,the greater number of them being conspicuously 
banded. Although many of them are very common, but 
little is known of their habits. It is thought that the 
_ NVomada deposits an egg on the mixed honey and pollen 
_ which has been collected by its host, and that it then 
closes the cell. At all events the Vomada has frequently 
_ been taken carrying pellets of clay attached to the posterior 
tibiz. They are mostly, but not exclusively attached to 
_ Andrena. J. sexfasciata is associated with Eucera longi- 
_ ¢ornis, a curious-looking long-horned bee, and WV. Faéri- 
_ ciana is found with Panurgus ursinus, a jet-black bee found
