NOTES ON ARADIDAE IN THE U. S. NATIONAL MUSEUM 



(HEMIPTERA) 



I. SUBFAMILY CALISIINAE 



By Nicholas A. Kormilev ^ 



Through the good offices of Dr. Reece I. Sailer and Dr. Carl J. 

 Drake, I had the privilege to study the unidentified Aradidae in 

 the collections of the U. S. National Museum in Washington, D. C, 

 including the Drake Collection. I wish to express mj'- thanks to 

 them. 



This paper, the first in a series, deals with the subfamily Calisiinae, 

 which is surely one of the oldest, if not the oldest, among Aradidae.^ 



All species of Calisiinae, with the exception of Aradacanthia multi- 

 calcarata Costa, are very small — less than 4 mm, long — and difficult 

 to collect. Consequently, our knowledge of their distribution and 

 habits is far from complete; but fragmentary as this knowledge is, 

 it indicates that Calisiinae are almost tropicopolitan, penetrating 

 sometimes into temperate zones; i. e., Calisius salicis Horvdth, 

 1913, was found in northern Yugoslavia and Calisius annulicornis 

 Bergroth, 1913, in Tasmania. No species are known from tropical 

 Asia, but Calisius salicis Horvdth is recorded from Syria, and 



' Formerly with Institute do Ciencias Naturales, San Miguel, Buenos Aires, Argentina. 



' In tbe division of Aradidae (or Aradoidea, as used by some modem European authors) I am following 

 the American authors, considering them as one family, with five subfamilies: Calisiinae, Aradinae, 

 Mezirinae, Isoderminae, and Aneurinae.
