AN APPEAL, IN BEHALF OF ENTOMOLOGY AND KINDHEO SCIENCES- 



In the interest of natural history it would be a good plan if every 

 naturalist throughout the Uuited States would petition their rep- 

 resentatives In Congress to have paragraph (iO(J of the tariff law of 

 1897 amended, so that specimens of natural history for scientific col- 

 lections be admitted free of duty, whether intended for private or 

 public use. The paragraph in question comes under the " free list ' : 

 and reads as follows : " Specimens of natural history, botany and 

 mineralogy, when intended for scientific public collections and not 

 for sale." 



Natural history, especially entomology, merits all the eii'-ourage- 

 ment possible and an excellent way to further an interest in it 

 would be to remove the barrier from the private .student. All who 

 read this are earnestly requested immediately to petition their rep- 

 resentatives at Washington urging that the section in question be 

 amended and that without delay- EDW. A. KLAGES. 



IN studying the relations between the species of the genus Cato- 

 cula I acquii'ed the conviction that for the solution of the problem 

 it is indispensable to resort, to experiments with elevated and re- 

 duced temperature after Standfuss. Some results from the breed- 

 ing of European species are already obtained. Unfortunately the 

 most interesting species, those with the black hind-wings, are in- 

 accessible to the European experimenter, the eggs of American cato- 

 calas not being on sale. 



I determined therefore, by your mediation, to address to the 

 members of the American Entomological Society and others a re- 

 quest to procure for me the living eggs of any species of Cntocalo r , 

 which are so abundant in the United States. The black species are 

 especially desired, the indication of the food-plant is also necessary. 



In exchange I can offer many species (well prepared) of my collec- 

 tion of Russian Lepidoptera. St. Petersburg, Crimean, Siberian.
