This small brown locust was originally described from numer- 

 ous specimens taken in Crawford and Lawrence counties, Ind., 



between June 24 and July 15, and has 

 not since been noted in the State. 

 Near Wyandotte, Crawford Co., it oc- 

 curred only along roadsides and in

upper slopes of the high wooded hills. 



In Lawrence County it was found to be rather common in mid- 

 July among the underbrush of high wooded slopes on the State 

 University farm, three miles southeast of Mitchell. Here the soil 

 was very sparsely vegetated, sedges and wild asters being the pre- 

 vailing herbs. The ground was covered with the dead leaves of 

 the last season, with whose colors the hues of the locusts so blend- 

 ed that they were invisible while motionless. The males leap briskly 

 when approached, but only for a short distance. The heavier 

 bodied females are more clumsy, and are easily caught with the 

 hand. 



In color and general appearance this locust bears a close re- 

 semblance to M. obovatipennis, but on comparing the two, morsel 

 is easily distinguished by its less prominent head, larger eyes, 

 narrower interocular space, more feebly sulcate frontal costa, 

 longer antennae of male, more coarsely punctate metazona, broader 

 tegmina of female and especially by the form of the male cerci 

 and furcula. It reaches maturity some time in June, while adults 

 of obovatipennis have not been noted till the last days of August. 

 The general range of morsel is probably southern, the only rec- 

 ords outside of Indiana being from Hocking Co., Ohio (Kostir), 

 and Hattiesburg, Miss. At the latter place Morse mentions (1907, 

 50) the finding of a pair in woodland on sandy river-bottom land 

 in company with M. riola. These he states were very large, the 

 male measuring 22, the female 28 mm. in length of body. The lo- 

 cust should be found on dry woodland slopes in various localities 

 in the southern thirds of Indiana and Ohio, and throughout Ken- 

 tucky and Tennessee.
