found upon sugar cane on the island of St. Christopher. Theone appears 
on the roots and the other in the axils of the leaves. Curiously enough, 
they appear to form two new species of a new genus near Dactylopius, 
which we hope to describe after further study on receipt of new material. 
The species on the roots, according to Mr. Barber, promises to cause a 
great deal of annoyance on estates not properly manured or cultivated. —

The young plants come up a sickly yellow or rusty color and require — 
frequent replacing. They manage, however, most of them, to throw 
the pest off with the reproduction of fresh roots, so as not to suffer 
materially. Mr. Barber noted 37 acres severely attacked. The planters — 
claim that lime and ashes are efficacious and also superphosphites. 
ANOTHER EMASCULATING BOT. 
Mr. F. Stephens, West Creek, California, sends us two * warbles ” 
taken from the body of a parasite mouse (Sitomys californicus). Mr. 
Stephens trapped the mouse on the upper Temecula River in California. 
The warbles were found in the scrotum, with air holes in the back part 
of the same. On the rump was a small Sore, which, on skinning, was 
found to contain another warble, dead and partly decomposed. Mr. 
Stephens thinks the mouse was able to reach this point with its head, 
and that it had killed the larva. The species is plainly Cuterebra, but 
differs from any which we have seen before, approaching, however, 
most closely to C. emasculator otf Fitch, which occurs abundantly in the 
east in the axillary regions and near the genitalia of the Red Squirrel 
and Striped Gopher. Mr. Stephens has promised to try to rear any 
further specimens which he may find, and we hope that other observers 
in the same locality will watch for this interesting form. 
THE EGYPTIAN ICERYA IN INDIA. 
In our last number we announced the finding at Madras, India, of 
Icerya egyptiacum, specimens of which we received through the kind- 
ness of Mr. Robert Newstead, of England. We wrote our corres- 
pondent, Mr. EK. ©. Cotes, of Calcutta, to ascertain whether the species 
was widespread in India, and he was fortunately able to find it at once 
upon Croton plants in the quadrangle of the Indian Museum. He 
also found it infested with secondary parasites identical with the form 
which we had received from Mr. Newstead, but was unable to find the 
primary parasite, which, however must exist and will undoubtedly be — 
found in the near future. The scale insect does not seem to be partie- 
wlarly abundant in India, and its rapid multiplication in Egypt is prob- 
ably due to the fact that the species is a comparatively recent intro- 
duction, and that it is an autochthon of India. Mr. Cotes finds that 
the Icerya is attended by an ant of the genus Cremastogaster, which 
he noticed busily prodding the scale insects with its antenne.
