Scale-insect on Betama (Cytisus jucundus). — Mr. McLach- 

 lan exhibited specimens from Mr. Morris, the plants growing 

 from 7,000 to 8,000 feet on the Peak of Tenerine. It proved to 

 be Mytilaspis pomorum, the Apple-tree scale insect. It was 

 first described as occurring in North America. It has also 

 been found in Guernsey on the Broom, which is closely allied 

 to Retama. 



Euonymus attached by Caterpillars. — Specimens of the 

 common Spindle-tree, infested with the web-forming Hypono- 

 meuta evonymella, were sent from Battersea Park, where they

 a photograph, taken by magnesium light, of a blossom of the 

 night-flowering Cereus growing at Loughborough.
