\ ORTHOPTEEA OF INDIANA. 183 



7.| IscHNOPTERA MAJOR (Sauss.-Zehiit. ) 

 i -^ Temnoptenj.r major Sauss.-Zelmt.. 1 35, 1893, 54; Scudd., 1 88, 1900, 8. 



Male: Size, large. Pronotum broadly elliptic, larger than in either 

 ol the two preceding species, membranaceous, the sides flaring, trans- 

 lucent; two deep oblique impressions on either side near the base. 

 Tegmina membranaceous, hyaline, longer than abdomen. Wings as 

 long as tegmina. 



Female: Body, stout, broad. Pronotum, short and wide, horn- 

 like, with no impressions; the hind margin nearly straight, the front 

 inargin rounded. Tegmina, abbreviated; covering only the basal seg- 

 ment of abdomen; rather broad, their inner edges overlapping, their 

 apices broadly rounded. "Sulcus analis deep, scarcely curved ante- 

 rior to the apex, reaching to three-fourths of the sutural margin." 

 Wings very small, narrow, pointed. Supra-anal plate large, tri- 

 angular, keeled, with apex bluntly rounded. 



Color: Male, a nearly uniform, light reddish brown. Two basal 

 joints of antennae yellow, the remaining portion, as also the cerci, 

 dark brown. Lateral margins of pronotum and of basal half of teg- 

 mina translucent whitish. Abdomen and legs pale yellowish brown. 

 Female: Pronotum reddish brown, the lateral margins indistinctly 

 yellowish or paler than the disk. Tegmina darker brown, their outer 

 margins dull yellowish. Abdomen and cerci piceous. Antennte as in 

 male; the legs darker. 



Measurements: Length of body, male, 21 mm., female, 17.5 mm.; 

 of pronotum, male, 5.5 mm., female, 5.3 mm.; of tegmina, male, 21 

 mm., female, 6.5 mm.; width of pronotum, male, 6.3 mm., female, 7 

 mm.; of tegmina, male, 6.2 mm., female, 5 mm. 



This roach has been taken in Indiana only in the vicinity of Wyan- 

 dotte, Crawford County. Immature females were first found May 9, 

 1899, and mature individuals of the same sex on July 7th of that 

 year. In 1902 more persistent searching proved the females to be 

 common during the last week of June and the first one of July, sev- 

 eral being taken with ootheca protruding. A single male, the only 

 one seen, was secured on July 3d. There is little doubt but that it 

 is one of the same species as the female, as it was found with two of 

 them, and differs from any other roach taken in the State. It is of 

 the exact color of I. ulderiana Sauss., described below, and is vesry 

 likely to be taken for an unusually large form of that insect. It may 

 be possible that it is a light form of I. roulnniana Sauss., of which the 

 females are unknown, as it agrees very well, except in color, with the 

 description of that species. If so, that name would have priority over 

 major, of which the males have not hitherto been found. There is no
