principles. Their successful study requires workers with absolutely 

 different training and wholly different technique. To combine them 

 into one service would be impracticable, except as units of a large 

 agricultural institution. Questions relating to the damage done by 

 insects to man and domestic animals are best handled by the economic 

 entomologists famihar with the whole range of entomological activity. 

 The term " economic entomology " seems more likely to take a firmer 

 hold in Europe than does the term " phytopathology," in this signi- 

 ficance, to gain ground in America ; this will mean that internationally 

 the term " economic entomology," as applying to the whole field, 

 will be generally adopted. That branch of the science relating 

 to the carriage of disease by insects is best carried on by trained 

 entomologists, and it is in this field that we must perhaps look for 

 the greatest advances in coming years.

Scale-insects are the pests most frequently imported, the chief being 

 Coccus hesperidum, L., occurring on bay trees from Belgium, Chrysom- 

 pJialus dictyospermi, Morg., on palms from Belgium, Hemichionaspis 

 asjndistrae, Sign., on Aspidistra and ferns from Belgium, Diaspis 

 boisduvalii on orchids from England, Chrysomphalus {Targionia) 

 biformis, Ckll., on orchids from Venezuela, Pseudaonidia p)(^&oniae, 

 Ckll., on azaleas from Japan, and Aidacaspis [Diaspis) pentagona, 

 Targ., on peach stock from Japan. Except in the case of greenhouse 

 species, all infested plants were destroyed. In 1914, a species of ant, 

 Iridomyrmex humilis, Mayr, was found on roses imported from 

 Germany ; this is an Argentine species and has been a pest in the 

 Southern States and California. It has recently been introduced into 

 South Africa and Portugal. In April 1914, the Calandrid, Eiwacto- 

 phagus graphipterus, was found in an orchid house at Summit, N.J. 

 This weevil is a native of Costa Rica. Ulex europea from England 

 was found infested by Apion ulicis, a weevil injurious to seeds. An 

 injurious imported beetle, Myelophilus piniperda, L., was discovered 

 attacking Scotch fir, boring out the tips of the central shoots, causing 

 the tree to assume a crooked branching habit ; this type of injury 

 resembles that of the white-pine weevil. Agrilus viridis, another 

 imported beetle, attacked roses in New Jersey. The larva bores 

 spiral channels in the sap-wood over which a gall forms. Cutting and 

 burning the infected stems during autumn or winter, seems the best 

 method of control. Callopistria fioridensis, the Florida fern cater- 

 pillar, was found during September 1914 injuring greenhouse ferns. 

 Up to the present it has yielded successfully only to handpicking, 

 supplemented by trapping the moths. The most serious discovery 

 was that of the eggs of Lymantria (Porthetria) dispar, L., and later the 

 capture of an adult male. The infestation occurred on evergreens 

 used for show purposes and was at least two years old. Eggs of 

 mantis are not infrequently imported from Japan. Damaster 

 hlaptoides, a large black Carabid, has been taken from Japanese 

 azaleas. Pterostichus (Feronia) vulgaris, L., another beneficial Carabid, 

 has been found on plants from Holland and Amara polita on others 

 from England. The latter fives on decaying vegetable matter and is
