ENTOMOLOGICAL NEWS. 



Published monthly (except July and August), in charge of the joint 

 publication committees of the Entomological Section of the Academy 

 of Natural Sciences, of Philadelphia, and the American Entomological 

 Society. It will contain not less than 300 pages per annum. It will main- 

 tain no free list whatever, but will leave no measure untried to make it a 

 necessity to every student of insect life, so that its very moderate annual 

 subscription may be considered well spent. 



ANNUAL SUBSCRIPTION $1.00, IN ADVANCE. 



Outside of the United States and Canada $1.2O. 



g^" All remittances should be addressed to E. T. Cresson, Treasurer, 

 P. O. Box 248, Philadelphia, Pa.; all other communications to the Editors

DUST. 



ONE of the greatest " bug-a-boos" to the bugologist is dust. 

 Dust on the glass or the drawers of cabinets; dust on the boxes 

 containing insects; .dust everywhere. Wooden cabinets, unless 

 extraordinarily well made, will admit large quantities of dust. 

 They are apt to warp, and the cracks in the back widen and dust 

 enters. Dust is not such a serious matter in private collections, 

 but in large museum collections, where it is hardly possible to 

 have some one constantly cleaning, it is a great nuisance. In 

 handling boxes or drawers one's fingers soon become black, and 

 often it is difficult to see through the glass of a drawer. The 

 entomological cabinet of the future, whether for drawers or boxes, 

 will undoubtedly be made of metal (tinned sheet iron or alu- 

 minum) w r ith a front of the same material closing on rubber. 

 Such a case is used by the ornithologists, and they find it a 

 improvement over old methods. 



^ILK-PRODUCING LEPIDOPTERA. Dr. Dusuzeau, Directeur du Lahora- 

 toire d'Etudes de la Soie, Rue St. Polycarpe 7, Lynn, France, desires to 

 obtain, either by way of exchange or purchase, specimens belonging to 

 the groups Saturnides, Bombycides, Lasiocampides, etc., from all parts 

 of the world; the eggs, larvae and cocoons are also desired, together with 

 information of the food-plant.
