548 FAMILY VII. TETTIGOXIIDJ3. THE KATYDIDS. 



species was taken in a field of dense millet and in a thick growth 

 of ragweed bordering the fence of a town lot. In the tidal marshes 

 it was found in the tall marsh-grass, tfp<irtin<t cynosuroides (L.) 

 and in a marginal fringe of switch-grasses. In fresh water bogs 

 it was taken on various grasses, cat-tails, sedges and bushes. 

 Unlike most members of the genus it appears to have a strong 

 preference for woodland habitats."

Size above the medium for the genus; form robust. Pale green fading 

 to dull yellow, the tegmina alone remaining in great part green; the usual 

 dark bars on occiput and pronotum vague, often broken into small oblong 

 fuscous spots ; antennae and tibiae uniform dull reddish-yellow. Fastigium 

 prominent, its sides divergent from base and rounded beyond the middle, 

 the apex therefore distinctly wider than base. Pronotum short, broad, 

 feebly sellate; metazona two-thirds the length of prozona, the transverse 

 sulcus in male deeply and broadly impressed, lateral lobes slightly deeper 

 than long, lower margin much less oblique, with hind angle much less nar- 

 rowly rounded than in nigripes; humeral sinus distinct, in male deeper 

 than in pulchellum. Tegmina surpassing hind femora 3 5 mm., exceeded 

 by wings 3 -4 mm.; their cross-veins very prominent, especially so in fe- 

 male. Cercus of male stouter than in nigripes. its apical portion more 

 evenly tapering; tooth shorter, stouter, more erect. Ovipositor distinctly 

 wider throughout its length than in either nigripes or pulchellum, less 

 curved than in the former, longer than in the latter (Figs. 179, 180, 7?,)

Tippecanoe Co., Ind., three males, five females (Fox). This is 

 the Orrlicliiitinn recorded by Fox (1015, :>18) as "O. nif/ripcs Scudd. 

 (variety.' 1 ) He states: "On October 13 and 14 I found a form of 

 this genus in a cat-tail marsh on the upland northwest of La- 

 fayette which I was unable to determine, but which Mr. Rehn, to 

 whom I submitted specimens, informs me is a race of 0. nifjripcs 

 from the typical form of which it differs in the absence of black 

 from the tibia? and, so far as my Lafayette material is concerned, 

 in its somewhat greater size. On the dates mentioned it literally 

 swarmed in the mixed cat-tail and rice cut-grass areas of the 

 marsh, but was entirely lacking in the marginal thickets." 



That this is a very distinct species from both iiigripcs and 

 pitlcliclliini is shown by the differences I have pointed out in key 

 and description. I was nt first inclined to consider it an un- 

 described form, but Dr. Fox, who made for me a drawing of the 

 male cercus, called my attention to its close similarity to that of 

 J)nl1<ititin as figured by R. & H. A comparison with their descrip-
