 of pronotum. 



Tegmina of female covering half of the abdomen, those of male 

 reaching nearly to its tip; inner wings shorter. The ovipositor is

of peculiar structure, being fitted for boring in wood, its upper valves 

 being short, broad and toothed like a saw on the posterior edge, 

 while the lower ones bear a strong hooked tooth at the tip. For other 

 structural characters see above under the genus heading. 



Measurements: Length of body, male, 20 mm., female, 24 mm.; 

 of antennae, male and female, 11.5 mm.; of tegmina, male, 11 mm., 

 female, 9 mm.; of hind femora, male, 13.5 mm., female, 16 mm. 



This handsome wood brown locust occurs throughout Indiana, but 

 nowhere in numbers. It makes its home in thickets, in the borders 

 of open woods, in grassy plots alongside old rail fences, and often- 

 times along the borders of streams in woodland pastures, but is 

 seldom seen in damp localities. In such places its hues correspond 

 so closely with those of the dead leaves, fallen grass stems and other 

 surroundings that it is seldom the insect is noted until it leaps 

 clumsily to one side. Mature males have been taken in Vigo County 

 on June 19th, an early date for locusts which have hatched from the 

 Qgg in spring. A single female with tegmina reaching slightly be- 

 yond tip of a])domen is in my collection from Vigo County. The 

 ordinary short winged female is apt to be confused with the brovm 

 females of Dicromorpha viridis, but can be readily distinguished by 

 the presence of the median carina oC vertex, and the curved lateral 

 carinas of pronotum. 



Interesting accounts of the egg-laying habits of the female of con- 

 sporsa have been given by both Smith and Scudder. I have, on a 

 number of occasions, noted the females with the abdomen inserted 

 in soft or decaying wood, and on August 11, 1893, I discovered a 

 fenuile in the act of boring a hole in the upper edge of the topmost 

 board of a si.x-plank fence. Tlie abdomen was curved downward, 

 and the toothed forcipate valves of the ovipositor used as pinchers 

 with wliicli small pieces of the wood were broken off. When dis-
