OETHOPTEEA OF INDIANA. 453 



and female, 8.2 mm.; of ovipositor, 5.5 mm. Width of tegmina, male, 

 4.7 mm. 



This is, next to fasciatus, the most common CEcantTius in central 

 and southern Indiana. Specimens are before me from Vigo, Putnam, 

 Marion, Floyd, Crawford and Posey counties. It 

 frequents shrubbery and weeds in fence rows and 

 gardens, and along roadsides; and while often found 

 in company with fasciatus, has never been seen mat- 

 ing with that species. A female was taken in Craw- 

 ford County on June 28th, an early date for a ma- * jo'intTofanren- 

 ture tree cricket. Scudder gives its range as ''New nx or (Ecanthus 

 York to Indiana." I have specimens from Agricul- Qua^^ipunctatua 

 tural College, Mississippi, and from Sherborn, Mas- 

 sachusetts, and have also found it abundant on the north shore of 

 the Niagara River, opposite Buffalo, New York, where it was the 

 only species presetit on September 4th. 



LIX. Xabea Walker (1869). 



The members of this genus may be known from those of CEcantlius 

 by the following characters: The first joint of antennae is armed on 

 its under side with a stout blunt tooth. The tegmina of female are 

 irregularly reticulated, the oblique longitudinal veins not being con- 

 spicuous; male tegmina with the mediastinal vein strongly arcuated; 

 the humeral angle wanting. Inner wings nearly twice as long as the 

 tegmina. Hind tibiae with neither spines nor serrations, armed with 

 only four apical spurs, two within and two without. First joint of 

 posterior tarsi unarmed, the tarsi clearly but three-jointed, the 

 second joint very short. 



But one species of Xabea is known from the United States, occur- 

 ring over most of the region east of the Great Plains.
