requires 30 to 40 days for its life-cycle, and by April the nest may be 

 about 12 inches in diameter. Towards the end of April both males and 

 females appear and mating takes place in June and July. These 

 hornets act as a check on many pests in Fiji, and should be regarded 

 as beneficial, though their sting is very painful to man and necessitates 

 the expense of canvas suits, gloves and veils for the workers that in 

 certain districts are obliged to enter the fields and destroy the nests 

 before the cane can be thrashed. In most localities, however, the cane 

 is cut during the hibernating period so that this difficulty does not 

 arise.

Cleaee (L. D.). a Useful Breeding Cage. — Bull. Entom. Research, 

 London, x, no. 1, November 1919, pp. 43-44, 1 fig. 



A useful, easily constructed and portable breeding cage is des- 

 cribed and illustrated. It consists of cylinders of brass mosquito- 

 proof wire netting, 20 meshes to the inch, held together by brass 

 paper-fasteners. Covers for the top and bottom may consist of glass 

 petri dishes, 8 to 10 inches in diameter or galvanised iron pans may 

 be used. These could be packed in nests and the wire carried in rolls. 

 These cages have the advantage of being rat-proof. Where earth is 

 necessary for pupation, the cylinder may be fitted outside the bottom 

 and this facilitates lifting oft" to replace the food-plant. When used 

 for tick-breediii^ experiments the cages were placed in larger dishes 

 containing water and kerosene, to prevent their escape ; this ako 

 renders them ant-proof. 



Baker (A. C). U.S. Bur. Entom. Neotoxoptera violae, Theo., and 

 its Allies. — Bidl. Entom. Research, London, x, no. 1, November

The Aphid discussed in this paper was recorded by Theobald on 

 violets in Africa and was described by him as Neotoxoptera violae 

 [R.A.E., A, iii, 749]. Investigation shows this species to be only an 

 aberration of Rhopalosiphmn violae, Perg., which occurs in green- 

 houses in the United States and Canada. 



This species and Macrosiphum Jcirkaldyi, Full., for which del Guercio 

 erected the genus Fullawayella, are closely related and undoubtedly 

 belong to the same genus ; they should therefore both be placed in 

 Fullawayella. The genus Micromyzus, which was erected by Van 

 der Goot for M. nigrum, which is evidently closely related to 

 F. hirkaldyi and is congeneric with it, must also become a synonym of 

 Fullawayella. Another allied genus is Microparsus, with M. variabilis, 

 Patch, as its type. 



A key is given to these genera and to the species contained in them.
