This species is quite distinct from the two previously 

 described. 



Huckton's description of 11. nodosum (Cameroons) is so bad 

 that one must rely on his figure. This apparently differs 

 from Distant's //. j^a^^erso/n' (Gold Coast) only in the dark 

 fuscous colour of the wings. It is therefore quite })rol)able 

 that Distant's species is merely a variety of nodosum^ Buckt. 

 The present species differs from H. pattersoni not only in the 

 shape and puncturation of the pronotal process, but in the 

 venation of the tegmen. In the former the first apical cell 

 extends to tlie base of the second subapical cell, whereas in 

 the latter it extends only halfway down the second sub- 

 apical cell. The presence of a costal stigma seems to be 

 characteristic of the genus. 



Mr. Dummer writes that this is a very rare Homopteron 

 which was secured by sweeping herbage for insects in the 

 forest-paths of the Mabira, near Mulangi^ 4000 feet, about 

 15 miles from the Ripon Falls to Nile commencement. He 

 remarks on its similarity to some of the biting-ants of the 

 district.

XLVI. — An un described Fish from the Coal Measures 

 of Lancashire. By E. Leonard Gill. 



The small fish here figured and described is one of the 

 specimens (No. L 8585) in the remarkable collection of 

 arthropod and other fossils gathered by the late Mr. W. A. 

 Parker from clay-ironstone nodules in the Middle Coal 

 Measures at Sparth, near Rochdale. With the rest of the 

 Parker Collection it is preserved in the Manchester Museum, 

 and I am indebted to the Keeper of the Museum, Dr. W. ]\I. 

 Tattersall*^ for the opportunity of examining it. 



Its remains occur in a nodule which has split almost
