This insect — closely allied to Meria, from which it may be dis- 

 tinguished by its abbreviated wings, and by the absence of the 

 small triangular cell which exists between the first and second 

 submarginal cells in the former — approximates to the division 

 which Guerin has suggested,* founded upon an insect figured by 

 Savigny in the great work on Egypt, j- and which the former 

 characterizes as differing from Meria " par les cellules des ailes 

 superieures, par la forme des jambes, et de leurs epines termi- 

 nales," the wings being of ordinary dimensions and adapted for 

 flight ; whereas in the present species they are merely rudimental, 

 employed (like those of the ostrich) as an adjunct to the legs during 

 rapid circumvolutions along the ground or in close proximity 

 thereto. The tibial armature also differs from that of Savigny's 

 undescribed species characterized as aforesaid ; while the sinuation 

 of the apical margin of the wing, not observable in the latter, is 

 strongly developed in the former ; the discoidal incision however, 

 which is present also in Meria, being probably a constant cha- 

 racter throughout the group. 



The following tabular statement may serve to indicate the 

 several divisions which have been proposed for Meria and its 

 allies: —
