346 REPORT OF STATE GEOLOGIST. 



This species closely resembles S. texensis in size and general ap- 

 pearance, and the females of the two are difficult to distinguish; the 

 males, however, are readily separated by the different form of the 

 notch of the supra-anal spine. The general color of the two species 

 is the same, but the yellow carinal lines of the pronotum are less dis-

tinct or wholly wanting in ^urviravda. The wing covers vary in 

 width, but are usually broader than in texensis; and longer and much 

 less broad, proportionally, than in the next species, S. pistillata. 

 The females of curvicauda are more robust, and have the serrations 

 on the margins of ovipositor less prominent than those of texensis. 



Measurements: Male — Length of body, 23 mm.; of tegmina, 35-37 

 mm.; of posterior femora, 28-30 mm.; of pronotum, 6 mm. Width 

 of tegmina, 7-8 mm. Female — Length of body, 25 mm.; of tegmina, 

 38 mm.; of posterior femora, 32 mm.; of ovipositor, 7 mm. Width 

 of tegmina, 8.5 mm. 



Curvicauda probably occurs in all portions of the State, but is less 

 common than texensis. It has been taken in Lake, Starke, Fulton, 

 Marshall, Kosciusko, Putnam, Vigo and Posey counties and is espe- 

 cially common about the marshy meadows bordering some of the 

 lakes and tamarack swamps of northern Indiana. The earliest date 

 on which a mature specimen ^vas taken was July 10th, in Knox 

 County. The general range of curvicauda is the same as that of 

 texensis. The habits of flight, as far as noted, are also essentially 

 the same as in that species. 



In New Jersey, according to J. B. Smith, both curvicauda and 

 texensis are very common on cranberry bogs, and destroy many of 

 the berries. They eat into the fruit to get at the seed, which they 

 devour, and leave the berry to dry up. A flock of turkeys which 

 will destroy the young of these katydids and drive off those that are 

 winged is probably the most effective remedy. 



Mr. S. H. Scudder, who has studied carefully the songs of many 

 species of Orthoptera and has even set a number of them, including 

 that of curvicauda, to music, has given a pleasing account of its
