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 Air. 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 year, 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 we 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 1 and not known 
outside of Europe till 1912 when Kieffer 2 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, Pedinomma rufescens as nearly 
as I can ascertain from descriptions which have been given by 
several writers 3 , but it does not seem probable on account of its 
wingless condition that our American species can be identical 
with the palcearctic one.
