THE EMBOLEMID GENUS PEDINOMMA IN NORTH 



AMERICA. 



By Charles T. Brues. 



Bussey Institution, Harvard University. 



Several years ago Dr. Joseph Bequaert showed me a strange 

 wingless Hymenopteron that had been collected by Mr. Wm. T. 

 Davis on Staten Island, New York in 1910. Neither of us was 

 able to recognize it at the time and he kindly allowed me to re- 

 tain the specimen for closer study. During early May of the 

 present 3^ear, when collecting insects in the Stony Brook Reser- 

 vation near Boston, Mass., Professor W. M. Wheeler found a 

 second specimen beneath a stone which I saw at once was 

 exactly similar to the one obtained by Mr. Davis. During the 

 remainder of the afternoon wc searched carefully for further 

 specimens in the neighborhood, but were unsuccessful. 



The insect proves to be a species of Pedinomma, a genus 

 described nearly a century ago by Westwood' and not known 

 outside of Europe till 1912 when Kieffer^ described as P. angus- 

 tipenne a species obtained by Prof. F. Silvestri at Coipue in Chile. 



The North American specimens agree quite closely with 

 Westwood's European species, Pedinomina rufescens as nearly 

 as I can ascertain from descriptions which have been given by 

 several writers^, but it does not seem probable on account of its 

 wingless condition that our American species can be identical 

 with the palsearctic one.
