518 FAMILY VII. TETTIGONIIDJE. THE KATYDIDS. 



Brunei' (1891) says it is found throughout the eastern part of 

 the state,, occurring more frequently in the natural groves grow- 

 ing along the principal streams. 



The known range of typical nebrasccnsis extends from Sarnia, 

 Out., and Ohio west to Minnesota, eastern Nebraska and north- 

 eastern Kansas and south and west to Clarksville, Teun., and St. 

 Louis, Mo. 



Walker (1904a, 338) states that at Sarnia, Out., by tracing 

 their song to its source, he found four males on August 12 in a 

 l.'.rge stretch of open grassy marshland bordering the St. Clair 

 Eiver. "The song was a loud penetrating continuous whirr, quite 

 suggestive of the dog-day cicada, but less clear and very unlike 

 that of N. aisiycr. It was heard only in the morning during 

 bright sunlight." 



235a. NEOCONOCEPHALUS NEBKA.SCENSIS LYRISTES (Rehn & Hebard), 1905, 



45. 



Differs from typical nebrascensis by the characters given in key, the 

 males separable only by their slightly less robust form, and in having the 

 stridulating field more narrow and elongate, the secondary veins heavy 

 only at junction with the primary one (Fig. 170, &.) Fastigium variable 

 both in length and breadth, in extremes in females extending 5 mm. be- 

 yond the eyes. Ovipositor ranging in length from 23 to 30 mm. but not 

 surpassing the tegmina in any of the specimens seen; in New Jersey fe- 

 males somewhat stouter with apical fourth usually more tapering than in 

 typical nebrascensis from Indiana. Length of body, $ and 9, 28 35; 

 of fastigium, 3.75; of pronotum, 7.2 8.8; of tegmina, $, 35.742.4, 9, 

 4452; of hind femora, $ , 2024, 9, 2326; of ovipositor, 23.330.7 mm. 



After studying at Philadelphia the types of both forms and 

 comparing with them Indiana specimens of what Brunei' named 

 for me as ncbrascensis and New Jersey, Virginia and Florida 

 specimens of what is known as h/ristes, I have placed the latter as 

 the eastern and southern representative or race of nebrascensis. 

 Iso fixed character of specific importance has been given separat- 

 ing the two. Rehn (1906b) says the males differ in that nebraft- 

 censis "is of a more robust build, with broader tegmina, wider and 

 more arcuate tympanum, more expanded caudal section of prono- 

 tum and deeper lateral lobes of the same;" all of which charac- 

 ters are comparative only and fall within the limits of individual 

 variation as shown by the specimens examined. R. & H. in their 

 key (1915, 309) separate the two only by the terms "form robust, 

 vertex slender," nebrascensis and "form slender, vertex heavy," 

 lyrist es. In their later treatment they do not compare lyristes 

 with nebrascensis, but only with iiu'laiiuiliimix, a species with 

 much shorter fastigium and ovipositor. Davis (Ms.) states that
