ORTHOPTERA OF INDIANA. 323 



(female) as wide as the first joint of antennge; the front half but 

 little sloping downward, distinctly and widely sulcate in the male, 

 depressed but scarcely sulcate in the female, the lateral margins 

 sharp. Frontal costa faintly narrowed between the antennae, feebly 

 sulcate at and below the ocellus. Antennse about two-thirds the 

 length of hind femora in both sexes. Pronotum short, distinctly 

 widening on the metazona; the disk broadly convex; the hind margin 

 obtuse angled; the median carina low, but visible throughout, a little 

 less distinct on the prozona; the latter a fourth longer than the 

 finely punctate metazona. Tegmina reaching the tips of hind femora 

 in the female, slightly surpassing them in the male; of nearly equal 

 width throughout. P^xtremity of male abdomen but little recurved; 

 the cerci with the basal portion stout, four-sided, the apical portion 

 nearly as long, but narrower, bent upward and inward; an inferior 

 angle or process at point of bend; the apex broadly rounded. Fur- 

 cula consisting of a pair of well separated parallel cylindrical spines, 

 about a fourth the length of the supra-anal plate and overlying the 

 ridges of its median sulcus. Sub-genital plate very short, the ap^x 

 rounded, the lateral margins incurved near the base. (See Fig. 14, 

 Plate II.) 



Color: Above, dark brownish or fuscous, often with a reddish 

 brown tinge, below yellowish. Occiput and disk of prozona darker 

 than the metazona. A shining black bar behind eye extends back 

 along the upper third of lateral lobes of prozona; this bordered below 

 with brownish yellow. Tegmina brownish fuscous, more or less dis- 

 tinctly spotted with darker along the median area. Hind femora 

 brownish yellow, indistinctly and obliquely barred with fuscous on 

 the upper and outer faces; the lower face reddish orange; the knees 

 black above. Hind tibise usually pale blue, pinkish at tip, but some- 

 times red or dull yellow; the spines black. 



Measurements: Length of body, male, 18 mm., female, 34 mm.; of 

 antennge, male, 8 mm., female, 9 mm.; of pronotum, male, 4.5 mm., 

 female, 5 mm.; of tegmina, male, 15 mm., female, 16 mm.; of hind 

 femora, male, 11.5 mm., female, 13.5. 



This seems to be one of the rarest of our Melanopli, but a half 

 dozen or so specimens having been taken in the State during my 

 collecting, and they only in Vigo, Monroe and Marion counties. It 

 frequents blue-grass pastures, roadsides, and borders of cultivated 

 fields in upland or sandy regions, and when disturbed, flies noise- 

 lessly for a short distance. A mature male was taken in Marion 

 County on June 1, 1902. The species resembles M. femur-rulrum 

 and allanis in general appearance and is very likely to be confounded
