with no intercalary vein. The posterior femora are slender with 

 the apex reaching (female) or exceeding by half their length (male) 

 the abdomen. The valves of the ovipositor of the female are strongly 

 exerted.

In 1873 Stal, in Rec. Orth., I, saw fit to restore Acrida, Linn., re- 

 stricting it to Linnean species, Grillus {Acrida) /iasi//a and Acrida scr- 

 rata, Thunb. Both of these species had been included in Truxalis, 

 Fabr. , for more than one hundred years. The latter genus he re- 

 stricted to the Linnean species Grillus {^Acrida) brcvicornis and other 

 American s])ecies which have since been removed to other genera. 

 There is no doubt but that Stal had a right to restore the name Acrida. 

 Brunner refused to follow him in the restoration of Acrida and the re- 

 striction of Truxalis, but himself restored Truxalis in the Fabrician 

 sense and then suggested the name Metaleptea for the American genus. 

 For the present, Truxalis, Stal, must stand and Metaleptea will remain 

 a synonym unless Truxalis is restricted to some of the old world spe- 

 cies included in the genus by Fabricius; under which circumstances, as 

 T. brevicornis is the only species left to which it could aj^ply, Metalep- 

 tea would have to be restored.
