Paul Fischer, however, has not- met with it on the closely adjoining 
south-west coast of France. 
It may be added that Lamarck, iu his original description of the 
species, speaks of its being confounded with A. glacialis , and points 
out the differences between the species. A. M. Norman.

Since writing the above, on turning to Dujardin and Hupe, I find 
that they, as I have done, refer Linck’s and Pennant's form to 
A. glacialis .

Gentlemen, — On looking through the collection of Coccidm in 
the Students' Insect-Room at the Natural-History branch of the 
British Museum my attention was drawn to two insects labelled 
Aspidiotus bicarinatus. The tickets attached to these insects 
showed them to be the veritable types described by Walker in the 
supplement of the British Museum ‘ Catalogue of Homoptera,’ p. 306, 
as Aspidiotus bicarinatus. But upon examination I found them to 
be the dried larvae of a Limacodid moth closely resembling those 
of the Indian species Narosa conspersa. The caterpillar of this moth 
has a coriaceous integument with two well-developed dorsal ridges. 
As the specimens in question were received from North China, 
they are probably the larvae of some allied species. 
It is difficult to understand how the mistake could have origi- 
nated. In its dried state the caterpillar has certainly some super- 
ficial resemblance to a Coccid ; but its head and mouth-parts at once 
proclaim its true character. E. E. Green. 
Note on Irrisor Jacksoni, sp. n. By R. Bowdler Sharpe. 
In a letter just received from Mr. F. J. Jackson he has given 
some very interesting notes on birds, some of which he believes to 
be new to science. The Irrisor is certainly undescribed, and I 
herewith name it after the explorer.
