thick caruncle or pad. Rostrum protruded in front, thick and cylindrical, 
with many recurved spines and eight little tubular short processes at the 
tip, with a small lobe or pad. Mandibles of the length of the rostrum or a 
little longer, the end recurved and terminating in a sharpish point. 
Hab. In the gape of the penguin. 
This is evidently a true tick, having the characteristic rostrum and 
dorsal shield of the genus. I have found no species described exactly 
resembling it. : 
It may be supposed that so large a parasite must be greatly inconvenient 
to the penguin, but its position would seem also to offer easy opportunities 
for getting rid of it if the bird chose to do so.

A PARAGRAPH in “ Nature” of COPS 1884, referring to my last 
paper on New Zealand Coccids, recommends me to try the application of 
kerosene to infested trees. This recommendation is more particularly 
directed to the case of Icerya purchasi. In another part of the same 
journal, I find a notice of some papers by Professor C. V. Riley, of Wash- 
ington, in which the use of kerosene is also urged; and the remedy is 
characterized by ** Nature” as * new." Considering that ever since 1878 
I have been constantly preaching the employment of kerosene against scale 
insects, often against adverse criticism, it is not a little amusing to me to 
receive advice to try the very thing which, in my first paper in these Trans- 
actions, I originally proposed. “ Nature” perhaps also overlooks, in con- 
nection with Icerya purchasi, that there is some difference between treating 
garden plants, or even orange-trees, and perhaps several acres of forest, or 
trees fifty feet high, or many chains of gorse fences. 
In the same paragraph exception is taken to the ‘‘ extreme roughness ” 
of the plates attached to my paper. Non cuivis homini contingit adire Corin- 
thum. We are not all artists, nor have we always in this country engravers 
who are able to improve the ** roughness " of our original drawings.
