THE WORK OF THE FUTURE. 



It is the intention of the ^vriter and of his colleagues in the study 

 of this family to work out the sjmonymy of described material which 

 has accumulated, to prepare synoptic tables of the different genera, 

 and describe the species which seem to be nev^' to science. These 

 papers will be issued from time to time as parts of the present bulle- 

 tin and of later bulletins of the Technical Series of this Bureau. 



The catalogue and bibliography of Coccida?. started in such a com- 

 prehensive and thoroughgoing manner by Mrs. Fernald. will be 

 continued in biennial supplements by Mr. J. G. Sanders, one such 

 supplement haying already been issued." 



One of the great difficulties in the study of Coccida? has been the 

 inaccessibility of the tj^pes of Maskell's many new species, especially 

 as the descriptions and figures were in most cases inadequate. It is 

 a pleasure, therefore, to be able to announce that, through the cour- 

 tesy of Mr. T. W. Kirk, the Department is to be allowed to make a 

 critical examination and study of all of Maskell's types and other 

 material, which are now making their long journey from AYellington. 

 New Zealand, to Washington for this purpose. 



The field of Coccidse is a very large one, and there is plenty of room 

 in it for a considerable number of students, and the National CoUec- 



^Tech. Ser. No. 12, Part I, Bur. Ent., U. S. Dept. Agriculture. 1906.
