corn, and injury seems to be the more general where they are 

 most grown. The practical control of this pest in Texas offers 

 one of the most interesting and valuable problems to the 

 economic entomologist, which must be solved by demonstrat- 

 ing the general methods of culture which will control the pest 

 as has been done so effectively with the cotton pests. 



Conocephalus lyristes. 

 By James A. G. Rehn. 



Early in the year 1905 the author described this species on 

 the basis of a single male individual from Chokoloskee, Mon- 

 roe County, Fla.*. During the summer of 1905 a number of 

 specimens of this genus came into my hands for study, among 

 them being six specimens which closely resembled the Florida 

 form, the type of which was at that time not accessible. In the 

 meantime, Mr. William T. Davis had published a record of 

 Conocephalus nebrascensis Bruner, from Lakehurst, N. J., the 

 determination having been made by Mr. Caudell,t and to fully 

 determine the relationship of the latter species to the indi- 

 viduals in hand, I secured, through the kindness of Prof. 

 Bruner, an individual of his species. This, with the type of 

 lyristes now available, shows my seven specimens to be true 

 lyristes, which is not closely related to C. nebrascensis, the latter 

 being a species of no greater size but of a more robust build, 

 with broader tegmina, wider and more arcuate tympanum, more 

 expanded caudal section of the pronotum, and deeper lateral 

 lobes of the same. 



The specimens of lyristes mentioned above, in addition to the 

 type, are as follows :
