NOTE ON ADISTEMIA WATSONI WOLL. 



[Coleoptera, Lathridiidae.] 

 By F. M. WEBSTER. 



Very little seems to be known of the habits of this diminu- 

 tive beetle, and our literature is almost devoid of references 

 to the species. Mr. E. A. Schwarz was the first to record 

 its occurrence in this country, he having exhibited specimens 

 of it under the name Cartodere watsoni and made some re- 

 marks upon it at a meeting of the Entomological Society of 

 Washington held November 12, 1896.* 



The statement was made that it had first been observed in 

 a sack of Lepidoptera from Alaska but that later it had oc- 

 curred quite commonly in old flower pots about the buildings 

 of the Department of Agriculture. 



In his Revision of the Lathridiidas of Boreal America, b Mr. 

 H. C. Fall gave the American habitat as Washington, D. C., 

 " in drugs," " in dust from feed store," and " among Alaskan 

 Lepidoptera." The author made it the sole representative of 

 his new genus Adistemia, and gave its distribution, outside 

 of America, as Canaries, Algeria, Cape of Good Hope, Portu- 

 gal, Venezuela, and Chile, and stated that the species was 

 described in 1871 from individuals taken on the interior walls 

 of a house in Funchal, Madeira. 



While located at Morgantown, W. Va., Dr. A. D. Hopkins 

 began the breeding of several varieties of timothy. On be- 

 coming connected with the Bureau of Entomology he brought 

 from West Virginia some material which was turned over 

 to the Bureau of Plant Industry and was planted on the 

 experiment farm of the Department of Agriculture at Arling- 

 ton, Va. As this timothy offered exceptional advantages for the 

 study of Isosoma with which some of it was badly infested 

 in July, 1905, some of the stems of these different strains of 

 timothy were cut off close to the ground, brought in from 

 the experiment farm, and soon after placed in sacks of swiss
