ORTHOPTEKA OF INDIANA. 



241 



very near the middle by the principal sulcus. In the male the hind 

 femora extend about 2 mm. beyond the end of the abdomen, and 

 are slightly exceeded by the tegmina. In the female, both hind 

 femora and tegmina are about equal, and exceed the abdomen less 

 than in the male. Other structural characters are given in the key. 



Color: Head and disk of pronotum either brown or green. A 

 broad reddish bro'WTi or black band behind the eye reaches back to 

 hind margin of pronotum; this limited above by the lateral carinas 

 of pronotum, which are whitish, but partially crossing the carina onto 

 the posterior third of disk. Sides of pronotum below the band 

 brownish. Tegmina either brown or green, with 

 a median band of equidistant square black spots 

 along their full length; in addition a few black 

 spots below the median band. Abdomen red- 

 dish brown, the sides spotted with black. Hind 

 femora brownish red, with traces of fuscous cross 

 bars; hind tibire pale brown, annulate with whitish 

 near the base. 



Measurements: Length of body, male, 17 mm., 

 female, 21 mm.; of antennae, male and female, 7.5 

 mm.; of tegmina, male, 16 mm., female, 18 mm.; of 

 hind femora, male, 10 mm., female, 12 mm. 



Although this small spotted locust is said to occur 

 in abundance in the United States east of the Eocky 

 Mountains, I have met with it but once in Indiana 

 during 15 years' collecting. This was July 27, 1897, 

 when I found it in abundance about the margins of 

 a small lake in one of the valleys among the sand 

 dunes near Millers, Lake County. 



It uses both the wings and legs in flight, and when close pressed 

 often burrows into the fallen grass in an attempt to escape detec- 

 tion. Of 21 specimens taken, but three were females, and they were 

 of the green variety. Five of the males were also partly green, the 

 remainder being brown and fuscous. Morse states that in New Eng- 

 land this species "begins to appear about the middle of July, being 

 a week or two later than speciosa, and may be found during the re- 

 mainder of the season. It is an active and alert species, leaping well 

 and also flying freely and well, sometimes for two or three rods. It 

 is found on the drier portions of the land adjoining salt marshes, 

 on the more densely grassed portions of ground just inshore of the 

 sandy beaches, and on sandy or loamy soil farther inland." It will 

 probably be found to occur m isolated localities throi^ghout northern 

 Indiana.
