The best food-plant for both univoltine and multivoltine races has 

 been proved to be Moms alba var. japonica, and M. alba var. philip- 

 pinensis, there being practically no difierence between the male and 

 female plants. 



Flemyng (W. W.). Sphinx convolvuU attacked by Larvae of Dipteron. 

 — Irish Naturalist, Dublin, xxvii, no. 1, January 1918, p. 13. 



An adult example of Herse (Sphinx) convolvuU captured in a garden 

 in Dublin was found, soon after capture, to be surroimded by a number 

 of minute pupae, from which 76 parasitic flies emerged. Mr. J. N. 

 Halbert appends the information that the parasite concerned was 

 Phora rufipes, Meig. 



Haviland (M. D.). a New Species of Myzus from the Thistle. — Entomo- 

 logist, London, li, no. 658, March 1918, pp. 49-50, 1 fig. 



Myzus carthusianus, sp. n., here described, was found among a 

 number of examples of Pemphigus lactucarius taken on thistle at 

 Godalming in 1916. This species somewhat resembles M. ribis, but 

 is of much smaller size and possesses longer cornicles. 



QuAiNTANCE (A. L.) & Baker (A. C). Aphids injurious to Orchard

This bulletin deals with the Aphids that attack the principal orchard 

 and bush fruits. 



Those infesting the apple are A. malifohae. Fitch (rosy aphis) ;; 

 A. pomi, De G. (green apple aphis), the result of infestation by which 

 is often confused with that of Empoasca mali, Le B. (apple leaf -hopper), 

 which distorts the leaves in a similar manner ; A. avenae, F. (oat 

 aphis) ; A. bakeri. Cow. (clover aphis) ; Eriosoma lanigerum., Hausm. 

 (woolly apple aphis), the control of which on the limbs and branches 

 is efiected by the usual contact sprays, but on the roots requires 

 different methods not considered in this bulletin. Minor apple pests 

 are Macrosiphum solanifoliae, Ashm. (potato aphis) ; A. rumicis, L. 

 (dock aphis) ; A. medicaginis, Koch (bur-clover aphis) ; Hyadaphis 

 xylostei, Schrank (wild-carrot aphis) ; A. crataegifoliae, Fitch (thorn- 

 leaf aphis), also called the long-beaked clover aphis, which is usually 

 found on hawthorn trees, but is not uncommon upon quince leaves, 

 which however it does not curl to the same extent as it does hawthorn 

 leaves. 



The most common species on the pear are A. pomi, A..ave7ioe and 

 A. bakeri, though Prociphilus corrugatus, Sirrine (woolly thorn aphis) 

 is common in some localities, occurring also on thorn, quince and 

 Juneberry. Two Aphids attacking the roots of pear-trees are Erio- 

 soma pyricola, B. & D. (woolly pear aphis) and Prociphilus pyri. Fitch. 

 The plum is attacked by three or four species of Aphids, two of which 

 are very injurious in some seasons. These are A. setariae, Thos. 

 (rusty plum aphis), injuring Japanese and native plums, and Hyalop- 

 terus arundinis, F. (mealy plum aphis), on the European type of plums.
