same author, 1794).

2. Acanthocephala nasula (Say) =|j femorata (Fabricius). 



3. Cletus signatus, Walker, 187 1, = || bipunctata (Westwood, 1842). 



4. C. bipunctatus, H.-S., 1S40, = pugnator, Lethierry & Severin, 1894, 



= armatulus, Breddin, 1905.

5. Arenocoris, Hahn, 1834, = Pseudophloeus, Burmeister, 1835, = 



Spathocera, Stein, i860. 



Pseudophloeus was proposed to supersede Arenocoris because the 

 latter was, etymologically, a hybrid ; it therefore must take the same type.
