ICERTA JEQTPTIACA, DoUglaS. 



A single adult ? of this pest has been forwarded to me, through 

 the kindness of Mr. Douglas, from the Royal Gardens, Kew. It was 

 imported from Calcutta on Aristolocliia saccata, received November 

 9th, 1S95. 



As this species has proved so destructive in the east, I learn that 

 the authorities at Kew thoroughly realize the importance of its dis- 

 covery in England, and that the most stringent measures have been 

 adopted for its speedy extermination. 



On December 7th, 1895, through the kindness of Miss Tomlin, I 

 also received several specimens from Calcutta on a plant unknown to 

 me. 



Chionaspis aspidistra. Sign., (J $ . 



I have a small colony of this species ou Asplenium, sp. It was 

 discovered by Miss Tomlin in a greenhouse near here, and is now 

 recorded for the first time as occurring in Britain. The ? , for the 

 most part, lives on the stems, while the ^ occupies the upper portions 

 of the fronds. My specimens were first identified as Ch. hraziliensis, 

 Sign. (Essai., p. 126) ; but Herr Sulc, who has very kindly examined 

 my specimens, says, " they agree to a hair " with Signoret's types of 

 Ch, aspidistrcE. 



As regards Oh. hraziliensis, Sign., Herr Sulc states there is no 

 original of this species in the Hof- Museum at Vienna ; and owing 

 to Signoret's somewhat imperfect description, it will be impossible to 

 identify the species with any certainty. Mr. Maskell (Trans. N. Z. 

 Inst., 1892, p. 210) has recorded Ch. hraziliensis from Australia, and 

 has also identified the species from Calcutta, where it was collected 

 by Mr. E. E. Green. Since Herr Sulc's valued information has come 

 to hand, Mr. Green is convinced that his specimens are the Ch. aspi- 

 distrce, Sign. ; and in all probability Mr. Maskell's specimens from 

 Australia are the same.

FOEFICULA AURICULAEIA. 



During the past year quite a new insect pest to hops has made 

 its appearance amongst the bines belonging to the S. Eastern Agri- 

 cultural College at Wye. This devastator was the common earwig 

 (^Forficula auricularia) , which has been so abundant generally during
