SUBFAMILY I. PIIANEROPTERINJE. 469 



214. SCUDDERIA CURVICAUDA (DeGeer), 1773, 446. Curve-tailed Bush 

 Katydid. 



Size large for the genus. Closely resembling texensis in size and ap- 

 pearance. General color pale green; head, pronotum, fore and middle fe- 

 mora and under surface tinged with yellow, usually fading to dull clay- 

 yellow in drying. Lateral margins of pronotum with yellow lines faint 

 or wanting. Pronotum broader in front and less distinctly divergent be- 

 hind than in texensis; humeral sinus less rounded, lateral lobes distinctly 

 longer, their hind margin less oblique. Tegmina shorter and somewhat 

 broader. Hind femora proportionally shorter. Notch of abdominal pro- 

 cess very different, as described in key. Female more robust with ovi- 

 positor broader, much less suddenly and strongly bent upward and with 

 serrations less prominent than in texensis. Length of body, $ , 18 23, 

 9, 1925; of pronotum, $ and 9, 56; of tegmina, $ , 2637, 9, 2838; 

 of hind femora, $, 2130, 9, 2132; of ovipositor, 7 S mm. Width of 

 tegmina, $ and 9 , 6 8 mm. 



This, the most robust of our northern species of Rcudderia, 

 probably occurs in all portions of Indiana, but is apparently less 

 common than texensis, especially in the southern counties. It is 

 abundant about the marshy meadows bordering some of the lakes 

 and tamarack swamps of northern Indiana. The earliest date on 

 which a mature specimen was taken was July 10 in Knox Co. In 

 autumn I have, for several years, found both it and texensis pres- 

 ent in numbers in company with Mecostethus lineatus and Clior- 

 tJiijt/Kis curtipennis in a muck meadow forming- part of a long 

 narrow swamp five miles northeast of Indianapolis. The two 

 katydids are so similar in appearance and habits of flight that 

 they cannot be told apart in the field, but when closely examined 

 are easily separated by the characters given in the key. As al- 

 ready noted, the earlier records of this species were largely based 

 on specimens of texensis, both Bruner and Scudder for many 

 years confusing the two. The *S'. curricfiuda of my first work on 

 the family (1893, 99) should be referred to tc.rcnsis and the S. 

 fnrcnl(tt<i (p. 100) to <-iirri<-<n/<l<i. The PJtfiiicroptcra angiistipen- 

 nis Harris (1841, 129) is also a synonym of curvicouda. 



The known range of X. ntrririitula, as here recognized, extends 

 from Maine and Nova Scotia north and northwest to the Severn 

 River, Ont., and Aweme, Man., and south and west to New Jersey, 

 Virginia, Tennessee and Nebraska. The species varies much in 

 size and appearance, R. & H. (1914a, 281) separating the smaller 

 northern individuals under the name R. <. foom/ //.<?. The char- 

 acters which they give in their key are comparative only, being 

 "size small, form compact; tegmina rather broad and short," and 

 in their original description they give not a single fixed char-
