general range of pennsylvanica is given by Scudder as "Northern

6. ISCHNOPETRA IN^QUALIS SauSS. — ZellU^ 



Ischnoptera inieqitalis Sauss. — Zehnt., 13 5, 1S9.H, 3fi, Plate 6, Figs. 14- 

 17; Scudd., 188, 1900, 7. 



Male: "Fuscous or fusco-ferruginous, with brownish antennae. 

 Head with face testaceous; in middle and on vertex, black. Pronotum 

 elliptical, with distinct impressions, the disk slightly convexed, 

 smooth, wholly black or fuscous or castaneous, with lateral margins 

 testaceous, translucent. Tegmina fuscous or slightly rufous in color, 

 basal area with anterior margin hyaline. Wings subvitreous, with 

 anterior and apical margins rather broadly infuscated. Vena ulnaris 

 with six or seven branches; besides this, with incomplete branch and 

 other rudimentary ones, not reaching the vena dividens. 



Female: "Pronotum horny, parabolic, with anterior and lateral 

 margins semi-elliptical, and the posterior margin transverse, broad, 

 subangular, with lateral angles slightly rounded. Disk a little con- 

 vex, with no impressions; fuscous-black in color, with yellow lateral 

 margins. Tegmina abbreviate, covering first segment of the abdo- 

 men, blackish-fuscous in color with distinct veins, apex widely 

 rounded and costal area yellowish in color. Wings rudimentary, 

 yellowish, not covering medial segment, with apex fuscous or 

 spotted." 



Measurements: Length of body, male, 21 mm., female, 16 mm.; 

 of pronotum, male, 5.2 mm., female, 5 mm.; of tegmina, male, 23 

 mm., female, 8 mm.; width of pronotum, male, G.3 mm., female, G.5 

 mm.; of tegmina, male, 6.8 mm., female, 5.2 mm. 



Specimens from Crawford County, Indiana, were identified for me 

 as this species by Prof. L. Bruncr. I have since secured a copy of the 

 description of Sauss.-Zehnt. — the only one extant — quoted above, 

 with which the Indiana examples fairly agree. The species is very 

 close to /. pennsylvanica, and may prove only a variety. The meas- 

 urements are very nearly the same. The general color of the pro- 

 notum and tegmina is darker, approaching a fuscous. The pronotum 

 is proportionally narrower in front, with the sides more distinctly 

 deflexed and the sub-basal impressions more distinct. The females 

 of tlie two are even more difficult to distinguish than the males. 



The Crawford County specimens were taken in late June beneath 

 flat rocks and chunks on high hills near Wyandotte Cave. Sauss.- 

 Zehnt., like many other foreign systematists, give a very general 

 range to the species they describe, recording this one from "North 

 America, Texas, North Mexico."
