 Species new to Britain. — Entomologist, London, xlviii, no. G28, 

 September 1915, pp. 212-213. 



Coenopachys hartigii, Eatz., was bred together with Hypophloeus 

 linearis, F., obtained from the burrows of Ips bidentatus, Hbst. 

 {Tomicus bidens, F.), in fallen branches of Pinus sylvestris. According 

 to Katzeburg, this insect has been bred from Oecophora {Harpella) 

 geoffroyella, but Marshall records the former host. The first specimen 

 emerged on 15th April, the last on 16th June. The dead twigs, etc., 

 from which the insects were bred, yielded 2 empty cocoons, which 

 were firmly fixed in the burrows of /. bidentatus

 Chronicle, London, Iviii, no. 1497, 4th September 1915, p. 154. 



In August 1914, figs at the Royal Horticultural Society's Gardens, 

 Wisley, were found to be attacked by Coccus {Lecanium) hesperidum 

 (soft scale). Other scales infested with a parasite were introduced and 

 the parasite estabhshed. In 1915, the scale, though present in small 

 numbers, has done no material damage. For over 2 years white fly 

 (Aleurodes) has been bred under control and recently a parasite of the 

 scale stage has been discovered. This parasite has multiplied rapidly 

 at Wisley and is available for distribution to infested greenhouses.
