Gubitellan cell or cells. XIV and supernumbers in all figures where it 

 occurs. 



The area between radiella and cubitella and bounded basall}' 

 by basella, or, when basella is wanting (figs. 5, 11), by intercubi- 

 tella. When basella is present the area may be divided by one or 

 two cross-veins (intercubitellae) forming two or three cubitellan 

 cells which are numbered from the base outward (figs. 1, 2, 3).

Discoidellan cell or cells. XVI and supernumbers in figures where 

 they occur. 



The area between cubitella and discoidella. In some Chalasto- 

 gastra it is divided by a cross-vein (recurrentella) forming two 

 cells which are numbered from the base of the wing outward.

Anellan cell. XVJI in all figures where it occurs. 



The area immediately behind submediella and brachiella and in 

 all wings in which anella is wanting, bounded posteriorly by the 

 hind margin of the wing: in those Chalastogastra in which 

 anella is present it forms the posterior boundary of the cell. 

 Occasionally divided by the interanella cross-vein (fig. 6).
