NEW AFRICAN TIPULID^. 



BY C. P. ALEXANDER, ITHACA, N. Y. 



The following species were given by Mr. Chas. W. Howard to Prof, 

 Needham, and later turned over to me for examination. There were four 

 specimens, representing three species, of which two are herein character- 

 ized as new. Mr. Howard's remark, that "the species were as thick as 

 gnats," is interesting.
