Marshall (G. A. K.). A New Weevil Pest of Sweet Potatoes in 

 Jamaica. — Bidl. Entom. Research, London, viii, no. 3-4, 

 February 1918, pp. 269-272, 1 fig. 



A new weevil, Palaeopas costicollis, sp. n., recently received from 

 Jamaica, is here described. The damage done to the tubers of sweet 

 potato crops by this insect is serious, and quite similar in nature to 

 that caused by the common West Indian pest, Euscepes batatae, 

 Waterh. As the two insects would almost certainly be confused by 

 untrained observers, it is very probable that some of the injury attri- 

 buted to E. batatae has really been due to this new pest. 



Two other species of this genus found by the author in the British 

 Museum collection, viz. : — P. subgranulatus, sp. n., from St. Vincent, 

 and P. grenadensis, sp. n., from Grenada, are also dealt with.

Twelve new species of African Aphids and four previously described 

 ones are dealt with in this paper, which is a continuation of one already 

 noticed [see this Review, Ser. A, ui, p. 748]. 



The new species are : — Macrosiphum dahliafolii, sp. n. , from Uganda, 

 on dahUas, the only other known species feeding on dahlias being 

 Aphis rumicis {A. dahliae, Westw.) ; Aphis durantae, sp. n., a very 

 small species from Egypt, living on the main and secondary veins on 

 the upper surface of the leaves of duranta ; A. zizyphi, sp. n., from 

 Egypt on Zizyphus spina- christi, swarming on the ends of the young 

 shoots ; A. ficus, sp. n., from Egypt and Uganda on sycomore fig 

 {Ficus sycomorus) especially on leaves attacked by Psyllids ; A. tama- 

 ricis, sp. n., from Egypt on Tamarix sp. ; A. bauhiniae, sp. n., from 

 Egypt on Bauhinia ; A. buddleiae, sp. n., from Cairo, where it occurs 

 in great numbers on the leaves of Buddleia madagascariensis ; 

 A. mathiolae, sp. n., and A. mathiolellae, sp. n., from Egypt on orna- 

 mental stocks ; A. pruniella, sp. n., from British East Africa, on plum ; 

 Hyalopterus insignis, sp. n., from Egypt, in colonies on the under-sides 

 of the leaves of reed grass or buffalo grass ; and Myzus pterisoides, 

 sp. n., from Uganda, on ferns. 



The previously described species are : — Aphis pomonella, Theo.^ 

 from British East Africa, on apple, this species being closely related 

 to A. pomi ; A. pheidole, Theo., found associated with ants {Pheidole 

 sp.) in N.W. Rhodesia ; A. acetosae, Koch, from Egypt, England and 

 Germany on Rutnex spp. and Papaver spp. ; and Siphocoryne (A.) 

 pseudobrassicae, Davis, which occurs in the United States on radish, 

 turnip, rape, kale, mustard, etc., and is now recorded from Cape 

 Colony. 



New localities and food-plants are recorded for the following : — 

 Rhopalosiphum dianthi, Schrank, from Egypt, in great numbers on. 

 cabbages in company with A. brassicae, L. ; Hyalopterus pruni, F., 

 {arundinis, F., pJiragmificola, Oest.), previously reported from Cairo 

 on Primus spp. and various rushes {Arundo), now taken at Gizeh on 

 apricot in January and on reed grass in February, this grass being 

 the only alternative food-plant to the peach, apricot and plum. The 

 insect appears in large colonies on the under-side of the leaves of the
