north ill the Atlantic, namely Les Passages, near San Sebastian ; 

 Paul Fischer, however, has not met with it on the closely adjoining 

 south-west coast of France. 



It may be added that Lamarck, in his original description of the 

 species, speaks of its being confounded with A. glacudis, and pointa 

 out the differences between the species. A. M. Nokman.

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 CoccidaB 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. Bowdlee 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 und escribed, and I 

 herewith name it after the explorer.
