have been included in the above description. Distant founded the genus 

 on a specimen with incompletely developed hemelytra (possibly a nymph) 

 and was thus unable to represent the venation in his figure, and 

 Kirkaldy says nothing about it although he had a macropterous specimen 

 before him. The cell of the membrane is very elongate and curved 

 toward the base, and the basal margin of the cell is parallel to the 

 costal margin, separated from it only by a very narrow elongate cell 

 lying in the longitudinal axis of the hemelytron. 



N. B. — Under the name Ghilianella congoënsis Schouteden has de- 

 scribed an African species which he later placed in Ischnonyctes, but as 

 it is stated to have the fore tarsi one-half longer than the tibise, it is 

 certainly not a species of that genus. It has fully developed hemelytra 

 and probably belongs to Gomesius or some allied undescribed genus.
