SUBFAMILY IV. COXOCEPHALIX J5. 551 



azona feebly ascending, two-thirds the length of prozona; lateral lobes 

 slightly longer than deep, lower margin straight, oblique, its hind angle 

 obtuse; humeral sinus scarcely evident. Tegmina not or very rarely reach- 

 ing tips of hind femora, surpassed by wings about 2 mm. Hind femora 

 robust, armed on lower outer carina with three or four spines. Cerci as 

 in key and Fig. 179, g, their tips subdepressed and tapering to a dull point; 

 notch of subgenital plate shallowly U-shaped; styles short, their tips ob- 

 tuse. Ovipositor about half as long as hind femora, rather broad, regularly 

 curved. Length of body, $, 19.5 23, 9, 17 20; of pronotum, $, 5.2 

 6.2, 9, 5.66; of tegmina, $, 1619, 9, 16.5 18; of hind femora, $, 17 

 21, 9, 1920; of ovipositor, 99.6 mm. (Fig. 182, c.) 



Clarksville, Tenn., Aug. 13, 31 (Fox}. The known range of this 

 species is mostly southwestern extending from southeastern 

 Illinois and north-central Tennessee west to Colorado and south- 

 west to central Texas. East of the Mississippi it has before been 

 recorded only from Olney, 111., a female taken there by Ridgeway 

 being in the U. S. National Museum collection. 



It is a rather short bulky species, resembling a small rnh/arc, 

 the male being easily known by the long, slender, sharp-pointed 

 tooth of cerci, the female more difficult to separate but known by 

 the less robust fastigium, very faint humeral sinus, and armed 

 hind femora. R. & H. (1915a, 48) state that "This species is 

 clumsy in its actions, and once located, easy to capture. In Texas 

 it was found in a great variety of situations, ranging from high 

 grass to 12 feet above the ground in post oak. It was taken in 

 grass among cotton, in green weeds, low bushes and in tall nettles 

 as well as in bushes in pine woods. The stridulation is not loud." 



The JL. (0.) cuticularc Redt. (1891, 503) nee. Serville is placed 

 by R. & H. as a synonym of cal carat tan. 



Group II. THE COXCIXXUM GROUP OF ORCHELIMUM. 

 Here belong seven nominal species and two varieties having the 

 apical portion of male cercus distinctly longer than the basal por- 

 tion. In size and form (except in sn/icrbiiiii } they are generally 

 smaller and more slender than the members of Group I, and the 

 ovipositor, except rarely in concinniun, is always more than half 

 the length of hind femora. 



KEY TO EASTKKX SPECIES OF GROUP II OF ORCHELIMUM. 



a. Apical portion of male cercus not strongly tapering to an acute apex; 

 tooth of cercus (except in sitperbum) arising as usual from the in- 

 ner side of shaft and not strongly recurved toward base ( Fig. 183, 

 c) ; upper margin of ovipositor (except in delicatum) regularly 

 and evenly curved. 



7;. Humeral sinus of lateral lobes distinct (Fig. 184, a); tooth of 

 male cercus normal in point of origin; smaller and more slen- 

 der, length of body in both sexes less than 21 mm.
