ORTHOPTEEA OF INDIANA. 



309 



moderately recurved; the cerci long, narrow, the middle third but 

 half as broad as the base, the apical third a little expanded and flat- 

 tened. Fnrcula consisting of a pair of minute rounded lobes. (See 

 Fig. 5, Plate I.) 



Color: Dull ash or wood brown above; greenish yellow beneath. 

 Head greenish yellow except on occiput, where it is brownish. A 

 dull blackish bar extends backward from eye along 

 the upper half of lateral lobe of pronotum; the 

 lower half of the lateral lobe greenish yellow. Hind 

 femora bright green (becoming dark in drying) ex- 

 cept the knees, which are black. Hind tibias green, 

 the spines black. 



Measurements: Length of body, male, IG mm., 

 female, 20 mm.; of antennje, male, 9 mm., female, 8 

 mm.; of pronotum, male, 4.5 mm., female, 5 mm.; 

 of tegmina, male, 3 mm., female, 4 mm.; of hind 

 femora, male, 9.5 mm., female, 11 mm. 



This is, next to M. scudderi, our most common of 

 the short-winged members of the genus. It prob- 

 ably occurs throughout the State, but has not been 

 noted in the counties south of Monroe and Knox. 

 It frequents rather low, wooded blue-grass pastures 

 and is especially fond of resting and mating upon 

 the foliage of the iron weeds (Veriionia) which 

 grow abundantly in such places. It is also partial 

 to the tall grasses growing in ravines and along the borders of sloughs 

 and marshes. In central Indiana the males begin to reach maturity 

 by June 15th, the females about a week later. By July 5th they are 

 mating in numbers. They have also been noted mating as late as 

 November 10th, and it may be possible that in favorable seasons, 

 a second brood matures. Like most other wingless species, they are 

 active leapers, the males, especially, being noted for their somer- 

 saults while endeavoring to escape capture. The range of gracilis 

 is given by Scudder as "Indiana and Kentucky to Nebraska and 

 Dakota."

Male below the medium in size; female larger and more robust. 

 Head not prominent, the vertex but little swollen, and not at all 

 (male) or a little (female) elevated above the pronotum; the inter- 

 space between the eyes very narrow, about as wide (male) or less 

 than one and one-half times as wide (female) as the basal Joint of
