what lost and the cells become reduced, as shown in fig. 7. 

 The cells of the second row from costa, after the third, be- 

 come longer and lose their hexagonal form, having the lower 

 side straight ; after the eighth cell the middle row is lost, 

 there being two large cells in place of three, but there is a

small middle cell immediately after, as shown in fig. 7. The 

 area between the subcosta and its upper branch (they ulti- 

 mately unite again as shown in fig. 7) is divided into three 

 very long cells, the cross-veins being opposite the fourth of the 

 second series of cells (shown in fig. 5) and the basal part of the 

 seventh of the same series. From the subcosta to the radius 

 are four cross-veins, placed at wide intervals, the fourth being 

 shown in fig. 7 {Panorpa has usually two such cross-veins). 

 The radius and media at first run side by side, so that upon 

 superficial examination they look like one very stout vein ; at 

 the point where the radius branches the media bends down- 

 wards, as shown in fig. 4 (this differs from Panorpa in the 

 earlier branching of the radius). The radial sector forks, and 

 the lower branch forks again ; the upper branch of the latter 

 fork again branches, and its upper branch is connected by a 

 cross-vein with the upper main branch of the sector, so that 

 there is enclosed an elongated cell, very acute basally, obliquely
