Prof. Stal has divided this family into ten subfamilies: — 



A. Abdominal segments nearly equally long. 



a. Fore acetabula remote from llie hind border 



of the prostetliium. - - . 1. Blissida. 



b. Fore acetabula on the hind border of the 



prostethium. 

 * All the ventral incisures extending to the 



sides, 

 f Fore wings not wholly dilated, nor broader 



than the abdomen. 

 X Hook emitted by the subtensor vein. 

 § Proslernum and mesosternum with no distinct

 X Fore femora not or hardly thicker than the 

 liind femora, unarmed, or thinly spinulose. 

 Membrane furnished with an areolet in the 

 interior basal angle, 

 -f- Areolet of the membrane emitting two veins. 2. LvOiEiDA. 



-i — h Areolet of the membrane emitting one longi- 

 tudinal vein. - . - . 3. Malcida. 

 00 Membrane with no basal areolet. - - 4. Geocorida. 

 XX Fore femora much thicker than the hind 



femora, with many spines beneath. - 5. PAOHYORONTHinA. 



§§ Presternum and mesosternum with a distinct

fi Fore wings wholly dilated and broader than

** Third ventral incisure not extending to the 



sides, near which it is recurved. - - 9. Rhyparocmromioa. 



B. Abdomen contracted at the base ; second and 



third segments very long. - - lU. CoLOBATimisTiDA. 



The same author has divided these subfamilies iuto genera, as follows:— 



1. Blissida. 



A. Body slightly depressed. Fore legs much incras- 



sated; tibiae with many spines, much shorter 



than tbe femora. . . . - Cuelochirus. 



B. Body considerably depressed. Fore femora and 



fore tibia; nearly equally long, the latter 

 neither incrassated nor spinose. 

 a. Middle legs very reinote from each other. Hind
