CUEEANT. 



Currant branch infested by White 

 Woolly Scale. 



These very active young 

 Scale insects (fig. 2, p. 306) 

 were whitish or orange in 

 colour, of a flattened oval 

 shape, broadest near the 

 head, deeply cleft at the 

 caudal extremity,with a long 

 hair or filament on each side 

 of the cleft, that is, one long 

 filament placed on each 

 lobe caused by the cleft, 

 and in the centre of the 

 cleft a long cylindrical pro- 

 cess. The body somewhat 

 raised along the centre, 

 with slightly indicated cor- 

 rugations along it, and side 

 ridges from it, and the sur- 

 face slightly sprinkled with 

 white or woolly morsels. 

 Eyes dark or black. One 

 of the special characteris- 

 tics by which this species 

 is known is the number and 

 length of the hairs on the 

 antennae, but in the size 

 figured I have only been 

 able to indicate that hairs 

 are present. 



The attack occurred on 

 Black, Eed, and White Cur- 

 rants, and on the orna- 

 mental kind commonly 

 known as the Flowering 

 Currant ; possibly also on 

 the Mountain Ash. Al- 

 though the first duly iden- 

 tified observation of the 

 appearance of the P. ribesics 

 in this country did not 

 occur until the past season 

 (1889), yet an attack which 

 is now recognised as the 

 same was observed so far 

 back as 1880 ; and notes 

 from various places accom- 

 panying specimens sent
