Exhibitions. 



Two New British Coccids. — Mr. E. E. Green exhibited 

 two new and (at ])resent) undescribed species of British 

 Coccidae, both belonging to the genus Lecanium and both 

 occurring on the Birch {Betula alba). 



One of them is quite a large and conspicuous insect. A 

 single example of this species was taken, at Camberley, last 

 year, when a diligent search failed to produce any further 

 specimens. This year, however, the insect has turned up in 

 comparative abundance, upon the stems and branches of 

 young birch saplings. Its presence is rendered still more 

 obvious by the attentions of a large ant {Formica ntfa). In 

 life, the dorsum of the insect is more or less covered with 

 greyish-white cobwebby secretion which gives it a " mil- 

 dewed " appearance. This secretion has been removed (by 

 ether) from one of the examples exhibited, revealing the 

 actual colour of the insect, which is seen to be bright cas- 

 taneous, wnth a narrow black median longitudinal stripe and 

 six or seven irregularly mottled black transverse bands. An 

 exami)le of the male puparium is also shown.
