OETHOPTERA OF INDIANA. 227 



broader, the upper posterior notch of lateral lobe of pronotum is 

 deeper and the median lobule more rounded than in holivari. 



A single female, now in the collection of Dr. Hancock, was taken 

 from the border of a large cypress swamp in Kno-x County, on July 

 6, 1903. It was not recognized until Dr. Hancock made a careful 

 examination of the Indiana material of the sub-family. A second 

 visit Avas made to the place on April 23, 1903, but a careful search 

 resulted only in the finding of four half-groA^oi nymphs. The whole 

 swamp was covered with water several feet in depth, and the young 

 of liancocki were found in company with the young and adults of 

 other Tettigids on the higher ground bordering the water, within 

 ten feet of its margin, and only a few rods from the nearest cypress 

 trees. All other known members of the genus are from the southern 

 states, and it is interesting to note that this single northern species 

 makes its home among the isolated cypress swamps of Indiana — the 

 cypress being a tree whose main distribution is far to the south.* 



XV. Paratettix Bolivar (1887). 



From the other grouse locusts the members of this genus may be 

 readily known by the short and narrow vertex which does not extend 

 beyond the eyes, its front margin being truncate. Frontal costa 

 more or less prominent between the antennae, declined toward their 

 base, rarely a little sinuate. Eyes prominent, sub-globose. Antenna 

 of 14 segments. Pronotum with its dorsal surface flat, its front mar- 

 gin truncate, and, in our species, advanced forward upon the head to 

 the eyes; its posterior portion moderately prolonged; the median 

 carina low. Togmina oval or elongate, punctate. Inner wings usu- 

 ally fully developed, rarely abbreviated. Hind tibiae with their 

 apical third gradually enlarged, the pads between the spurs of last 

 joint of hind tarsi covered with numerous fine points or spicules. 

 Five species of the genus are known from the United States, one of 

 which occurs in Indiana.

*' Two additional females of N. liancocki were taken in the cypress swamp on July 1,1903' 

 by one of my assistants. The male has, however, not yet been discovered.
