FAMILY VII. TETTIGOXIIDJE. THE KATYDIDS. 



From these statements and from the study of the individuals 

 at hand I believe that it will eventually be found that some of the 

 four forms mentioned are only southern races or offshoots of one 

 or more of the better known northern species, and that the modifi- 

 cations of color and secondary sexual organs have been brought 

 about by the environment of the salt marsh areas which they in- 

 habit. The series of specimens of each at present available is not 

 sufficieut for me to express a more exact opinion of their rela- 

 tionship, and I have therefore left them as placed by their 

 authors. 

 272. CONOCEPHALUS SALTANS (Scudder), 1872, 249. Wingless Prairie 



Grasshopper. 



Size very small; form very slender. General color dull reddish-brown; 

 occiput and pronotum with the dark brown stripe bordered as usual each 

 side with one of pale yellow, the latter prominent in fresh specimens; sides 

 of abdomen also with a narrow yellow stripe. Fastigium strongly ascend- 

 ing, its sides rounded or distinctly divergent forward, the apex one-third 

 wider than basal joint of antennae. Lateral lobes with lower front angle 

 obsolete, hind one obtusely rounded; humeral sinus evident, very shallow; 

 convex callosity prominent. Tegmina usually strongly abbreviate, cover- 

 ing only about one-fourth of abdomen, their tips rounded; rarely macrop- 

 terous, with the tegmina slightly exceeding the tips of hind femora, and ex- 

 ceeded by wings 5 mm. Cerci as in key and Fig. 189, d. Ovipositor as 

 long as or longer than body, very feebly curved. Length of body, $ , 11 

 14, 2- 12.8 15.5; of pronotum, $ and 2, 3 3.5; of tegmina, short-winged 

 $, 33.5, 2, 2.52.7; long-winged 2. 22 ; of nind femora, and 2- 

 1112; of ovipositor, 13.515 mm. (Fig. 193.)

This, one of the smallest of the Conocephalinse, has as yet 

 been noted only at four localities in Indiana, namely, the border 

 of a raw prairie near Heckland, Vigo Co., where it was found in 

 small numbers Sept. 29 Oct. 21; near Lafayette, where Fox took 

 a single male in company with 0. attcntnilux in a cat-tail cut-grass 

 marsh; at Dune Park, Porter Co., Oct. 12, where a few individuals 

 were taken from the clumps of grass on the base of a sand ridge, 

 and near Pine, Lake Co., where a female was taken Sept. :> by 

 J. I). Hood. It appears to be less active than any other Cono-
