42 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



stippling may have no correlation with the intensity of the areas 

 on the lateral lobes of the pronotum. Rarely the dorsum of the 

 head, pronotum and abdomen has a pair of fine closely placed 

 medio-longitudinal lines of fuscous (certain specimens of glaher). 

 An invariable marking in the genus, although of variable extent 

 and width, is the whitish area at the position of the humeral 

 sinus of the lateral lobes of the pronotum. The general dorsal 

 color may be washed Avith rufous or even bright green, but this 

 is purely individual. Both A. glaher and calcaratus have their 

 surface more glabrous or even polished than the other forms of 

 the genus. 



Distribution. — The genus is known to range from as far north 

 as New Hampshire, northern Vermont (Sudbury), northeastern 

 New York (Lake George), southern Ontario (Arner), northern 

 Michigan (Porcupine Mountains) and Minnesota, south to ex- 

 treme southern Florida, southern Alabama (Opelika) and Missis- 

 sippi (Meridian and Natchez) and western Arkansas (Ozark 

 region), and from the Atlantic coast west to Minnesota, Iowa, 

 Missouri (record doubtful) and western Arkansas (Ozark region). 

 It is quite probable that the genus will be found to reach the Gulf 

 coast of Alabama, Mississippi and Louisiana, and also to extend 

 into eastern Oklahoma. The Minnesota record is merely a state 

 one and probably refers to the southeastern portion of the state. 

 Two species of the genus have Ijeen reported by Bruner from 

 eastern Nebraska, but his collection contained no material from 

 that region and we have not positively accepted these records 

 in consequence. 



Individuals of this genus prefer woodland situations, living in 

 the dead leaves and grasses, in low bushes and in wet meadowy 

 areas near woods. They are occasionally found in numbers 

 in low bushes along the edge of woods and at night we have found 

 them climbing on the trees to a height as great as nine feet 

 from the ground. Work with a flash-lamp will reveal them in 

 many situations in wooded regions and they frequently fall 

 victims to the molasses ground trap. 



The center of distribution appears to l)e the southeastern part 

 of the United States, five of the nine forms being found only in 

 that region; it is there we find the greatest diversity in the 

 genus and it is only in that general region that we find all four
