Size medium or small. Vertex but little elevated above the pro- 

 notum, the interspace between the eyes of the female, about as broad 

 as frontal costa, narrower in the male; its front half strongly sloping 

 downward; the median sulcus shallow. Frontal costa feebly sulcate 

 at and below the ocellus. Antennae about three-fourths (male) or 

 less than two-thirds (female) as long as hind femora. Pronotum with 

 the disk broadly convex; the prozona from a fourth to a half longer 

 than the densely punctate metazona, the median carina distinct, 

 but low and equal throughout; front margin truncate or nearly so, 

 and often faintly notched in the middle; hind margin obtuse-angled. 

 Tegmina about as long as the pronotum, broad ovate in shape, their 

 inner edges a little separated or just touching in the male, often over- 

 lapping in the female. Wings not half the length of the tegmina. 

 Cerci of male sub-falcate, about twice as long as their basal breadth; 

 the rounded apex about half as broad as the base. Fureula minute, 

 triangular. (See Fig. 2, Plate I.) 



Color: Dull reddish or Avood brown, nearly uniform in the female. 

 The male, and sometimes the female, with an indistinct dusky bar 

 reaching from the eye back along the upper half of each lateral lobe 

 of pronotum as far as the metazona. Hind femora with two faint 

 dark bars on their upper face, the knees blackish. Hind tibiae bright 

 red, often paler at base, the spines black. 



Measurements: Length of body, male, 19 mm., female, 24 mm.; 

 of antennaj, male and female, 8 mm.; of pronotum, male, 6 mm., 

 female, 7 mm.; of tegmina, male, 6 mm., female 7 mm.; of hind 

 femora, male, 11 mm., female, 13 mm. 



This short-winged, dull colored locust occurs throughout the State, 

 but is more common southward. On account of its short tegmina, 

 persons who are interested in Orthoptera are very apt at first to re- 

 gard it as a nymph of some other species. In the central counties it 

 begins to reach maturity about August 5th, and has been taken as 

 late as November 22d. It is one of the most common of the late au- 

 tumn locusts, frequenting the borders of open woods, fence rows and 

 roadsides, especially in dry situations where blue-grass abounds. On 

 warm sunny afternoons in November, it may often be seen resting 

 quietly on the sides of logs, or the lower part of rail or board fences,
