 The relatively slight injury caused by Clysia amhiguella to vines- 

 during the year under review may possibly be attributed to climatic 

 conditions, the very dry summer doubtless affecting the development 

 of the caterpillars of the second generation. Parasites were alsO' 

 very numerous during the year. Experiments with various insecti- 

 cides were continued and confirm previous observations [see thia 

 Review, Ser. A, vii, p. 46]. The sprays were applied by means of 

 a revolving jet which proved very much more efficacious than the 

 ordinary one. At light-traps a great number of Spargcmothis pilleriana 

 {Pyralis vitana) were caught, as well as C. ambigitella. Although no 

 damage has been so far recorded in Switzerland by tliis moth, it 

 may prove a serious pest at any time and its occurrence should therefore 

 be guarded against.

[Received 18th September 19i9.] 

 Mites, Xylehoms cofjeae, a Forficulid and Bruchid beetles of the 

 genus Pachymcrus have been found in a parcel of seed from British 

 Guiana. The Bruchid is considered to be Pachymerus nudeorum or 

 a closely allied species. All stages were found in the seed of the oil 

 palms, Attalea sfectahilis and A. coJmne. The mites and Xylehorus 

 eoffeae were found in the seed of Thrinax jparviflora and Borassus 

 flahelliformis. All these pests were killed by fumigating for 24 hours 

 with carbon bisulphide, about 5.^ oz. per 3G cub. feet. Of a total of 

 25 palm nuts, 24 were attacked by the Bruchid, and as 17 of the 

 infested nuts looked quite sound externally, it is obvious that the 

 importation of seed is hkely to be dangerous, and all parcels should 

 be submitted by the receiver to expert examination before opening.

 The w^eevil, Euscepes batatae, Waterh., appears to be the only pest 

 of sweet potatoes known in Brazil. An appeal is made to growers 

 to send in for identification specimens of any Coleoptera that may 

 be found attacking these tubers. In the case of E. batatae a knowledge 

 of the Brazilian States where it occurs would enable the others to 

 establish quarantine measures against it.
