ORTHOPTEKA OF INDIANA. 379 



In this species the body is rather slender and of more than aver- 

 age length; constant in color but dimorphic as respects the length 

 of wings, the long-winged forms, however, being very scarce. Sides 

 of head and body, together with all the femora, green. The usual 

 reddish brown stripe on occiput and pronotum narrowly edged with 

 whitish, especially on the fastigium of the vertex. Tegmina reddish 

 brown; in the females exceedingly short and pad-like, or well de- 

 veloped and reaching almost to knees; when the former, a little 

 longer than the wings, when the latter, 5 mm. shorter than the wings. 

 In the short-winged males (the only ones I have seen) the tegmina 

 are somewhat less than half the length of the abdomen. There is a 

 reddish brown band on dorsal surface of abdomen, darker where it 

 meets the green on sides. Ovipositor pale red, straight, one and a 

 half times the length of the posterior femora. Cerci of male, long, 

 the apical half acuminate, curved slightly inward near the tip. 



Measurements: Male — Length of body, 14 mm.; of tegmina, 5.5 

 mm.; of pronotum, 3.5 mm.; of hind femora, 13.5 mm. Female — 

 Length of body, 17 mm.; of tegmina, short-winged form, 3.5 mm.; 

 long-winged form, 16 mm.; of hind femora, 15.5 mm.; of ovipositor, 

 23 mm. 



Stridum is a common species in the western and northern parts of 

 the State, where it frequents, for the most part, dry upland meadows, 

 open pastures and prairies, and reaches maturity about August 1st. 

 The mature females are usually much more abundant than the males 

 and vary much in size. It is an active leaper'and tumbler and like 

 several of its allies, often strives to escape detection by burrowing 

 beneath fallen weeds and grasses. The general range of stridum 

 is to the west and southwest, it having been first described from 

 Texas, and not heretofore recorded east of Illinois, except in my 

 former paper on Indiana Locustidfe.
