egg-masses of Orgyia {Notolophus) antiqua, L. (vapourer moth) and 

 pupae of Apatela auricoma, F. (dagger moth) have been frequently 

 taken on stock from France and Holland. Cocoons, apparently of 

 the sawfiy, Emphytus cinctus, L., have been collected on roses from 

 England. The weevil, Anthonoftius bisignatus, Roel., was found 

 infesting seed of Primus sargenti from Japan, and the whole consign- 

 ment was fumigated with carbon bisulphide (3 lb. per 1,000 cub. ft. 

 for 24 hours). Parlatoria chinensis, Marlatt (chafE scale), was taken 

 on Pyius sinensis and P. ussuriensis from China, where it is apparently 

 a serious pest, injuring crab-apple. Hibiscus, Zizyphus and Thuja 

 orientalis. Larvae of Agrilus sp. were taken in galls on chestnut trees 

 from Japan ; Gracilaria zachrysa, Meyr. (azalea leaf-miner) was found 

 infesting azaleas from Belgium and Holland. 



On tropical plants the following were intercepted : Sternochetus 

 mangiferae, F. (mango weevil), in mango seed from India, and Coccus 

 mangiferae, Green, on the same plant from Cuba. Stenoma sp. and 

 an apparently vmdescribed species of Conotrachelus were found infest- 

 ing avocado seed from Guatemala. Avocado seeds from the same 

 country were also infested with the Coccids, Aspidiotus subsimilis, 

 Ckll., Aspidiotus sp. near A. cocotiphagus, Chrysomplialus scutiformis, 

 Ckll., C. personatus, Comst., Pseudoparlatoria ostreata, Ckll., Lepido- 

 saphes mimosarum, Ckll, Diaspis sp., Ceroplastes sp., Solenococcus 

 sp., Lecanium sp. and Coccus sp. 



Lepidosaphesjicus, Sign, (fig scale) was intercepted on fig trees from 

 Spain. Toxotryjxina curvicauda, Gerst. (papaya fruit-fly) was taken 

 in papaya fruit from Cuba. Among the scale-insects intercepted 

 were : — Phenacaspis eugeniae, Mask, on coconuts from Ceylon. 

 Antonina crawi, Ckll., on bamboo from Japan and Pseudococcus 

 sacchari (sugar-cane mealy bug) on sugar-cane from Jamaica, Trinidad 

 and Hawaii. 



Orchids are responsible for the introduction of many pests, at least 

 64 species having been collected on plants from South America. 

 Twenty of these species were ants, the majority of them now being 

 established. Pheidole anastasii, Emery, collected on Phormium tenax 

 from the Azores, is troublesome in greenhouses ; Prenolepis longicornis, 

 Latr., known as the crazy ant, is a household pest as far north as Boston. 

 A species of Iridomyrmex was found in a shipment of Theobroma cacao 

 from Java. Parallelodiplosis cattleyae, Felt (cattleya midge) was 

 collected on orchids from Central and South America, as well as 15 

 species of scale-insects from various countries. All orchids arriving 

 from countries without a recognised inspection service are now being 

 fumigated at the port of entry. 



A list of countries is given with the number of species of insects 

 imported from each,

In the course of investigations regarding the European poplar 

 canker {Dothichiza populnea) in Pennsylvania nurseries, it was observed 

 that in a block of balsam poplars that were seriously infested with 

 Cryptorrhynchus lapathi (poplar weevil) all the trees were also badly
