The following new genera have been proposed recently ; but, 

 having no personal acquaintance with the species concerned, I can 

 only quote the characters given by their founders : — 



Alecanopsis, Ckll. — ' Adult 9 dark red-brown, very convex, 

 abdominal region conspicuously segmented ; antennae short and 

 thick, six-jointed ; legs very short, rudimentary ; Australian.' 

 (Cockerell, Canadian Entomologist, Feb. 1901.) [Apparently a 

 geographical genus. With difficulty separable from Lecanopsis. — ■ 

 E. E. G.] 



Toumeyella, Ckll. — Similar to Alecanopsis, but adult 9 not 

 conspicuously segmented, (Cockerell, Canad, Entom., Feb. 1901.)
