FRED. V. THEORALD — 



Food-plant : Thuja orientalis. 



Described from a number of apterae and nymphae sent me by Mr. Gerald 

 Bedford. I can find no described Lachnid from Thujas similar to it. In the 

 young forms the colour seems paler and the proboscis may project beyond the 



Fig. 17. — Lachniella thujafolia, Theo., apterous viviparous 2 ; (A) antenna, (B) proboscis, 

 (C) dorsal view of cornicle, (D) lateral view of cornicle ; (E) cornicle of immature 9 



body. The nymphae generally resemble the apterous females, but the fifth 

 antennal segment is markedly longer than the fourth and quite as long as the sixth. 

 This is probably the aphid that Fuller refers to as being common on the hedges 

 of Thuja orientalis in Natal." Mr. Bedford says it seems to be common in the 

 Pretoria district.
