68 A?inals Entomological Society of America [Vol. XI, 



date of May 20, 1917, suggested with admirable foresight, that 

 the species perhaps belonged to the tribe Cylindrotomini of the 

 Tipulid^; but, as material had not then been forwarded to him, 

 he could not naturally diagnose the species from a brief, written 

 description. Later, however, he was able to corroborate Mr. 

 Alexander's determination from specimens sent from the 

 writer's collection.

 grandis. About natural size. (Original.) 



The intrinsic value of the discovery lies in the fact that, 

 according to Mr. Alexander, this represents the first finding of 

 the immature stages of any species of the genus Cylindrotoma 

 on the American continent, and it is hoped that the publication 

 of this paper will stimulate other entomologists to search for 

 these very interesting larvae. A study of their habits will well 

 repay one's efforts by reason of their decided contrast to those 

 of the generality of Tipulid larvae.
