CONCERNING SOME HYDROMETRA FROM 
AFRICA (HEMIPTERA) 1 
By H. B. Hungerford 
University of Kansas 
In the Annales Musei Nationalis Hungarici, Vol. XXVIII, 
1934, there appeared an article entitled “The Hydrometridae 
of the Hungarian National Museum and other studies in 
the Family” by Hungerford and Evans. This paper con- 
tains drawings of most of the known species and keys for 
the separation of all of the species of the world known 
to the authors. Twenty-five of the sixty-six Hydrometra 
treated are described as new. Unfortunately there occurred 
a lapse of several years between the completion of the manu- 
script and its publication and in the interim three papers 
describing new Hydrometra appeared. However, only H. 
ugandae Jaczewski is from Africa. Since 1934 six more 
African species have been described, five of them by Poisson 
and one by Hoberlandt, and some specimens have been re- 
ceived by me for study, including two undescribed species. 
I am indebted to my friends Dr. J. C. Bradley and Dr. 
F. X. Williams for the opportunity to study the Hydro- 
metra taken by them during their recent trips in Africa. 
Dr. Bradley’s material was sent to Cornell where Henry 
Dietrich was kind enough to forward it to me. Dr. Williams’ 
material was promptly forwarded by Dr. Bequaert from 
the Museum of Comparative Zoology at Harvard and we 
have mounted and labeled this material to avoid any delay 
in its study. 
In the material collected by Dr. J. C. Bradley are the 
following : 
Hydrometra albolineolata Reuter 
Tonga, Sudan, Oct. 28, 1948, White Nile, lat. 9°-28' N., 
long. 31°-2', J. C. Bradley, 1^,3 $ $ (Cornell) ; 1 $ , 1 $ 
(F. H. Snow Coll.).
