T. braueri Friese, from Brazil, but readily separated by the black

SYNOPTIC KEYS TO THE LYGAIDA (HEMIPTERA) OF 
THE UNITED STATES. 
By H. G. BarBer, 
Roselle Park, New Jersey. 
Part I. 
Several months ago I was requested by Dr. W. E. Britton of 
the Connecticut Agricultural Experiment Station to prepare a 
list of the Lygeeide occurring in Connecticut, with suitable keys, 
for the proposed list of Hemiptera of the state. As a basis for this 
work I found it necessary to construct synoptic keys of all of the 
subfamilies, tribes and genera for the entire United States. As so 
much time and study has been spent in their preparation, and as 
no such keys covering this family, restricted to our fauna, has ever 
been published, it seems advisable to publish these in the hope that 
they may be of service in solving some of the difficulties experienced 
by systematists in this troublesome group. Professor Gregory, 
superintendent of the Connecticut Geological and Natural History 
Survey, and Dr. Britton have kindly given their consent to this 
publication in advance of the appearance of such parts as apply 
only to New England Lygide. 
I have used as a basis for these keys Stal’s ‘Genera Lygeidarum
