A NEW SPECIES OF PHYLLOSTICTA. 
J. B. Ellis and W. A. Keeler man. 
This species was found in October on fallen leaves of the White 
Poplar (Populus alba) at Waynesville, Ohio (W. A. Kellerman)/ 
occurring in small, light-colored spots on the upper surface, and 
associated with an ascomycetous fungus. It may be described as 
follows : 
Phyllosticta alcides Ell. & Kellerm. — Spots cinereous, 
epiphyllous, subindefinite, 2-4 mm. diameter, raising and punct- 
uring the epidermis, soon perforated above. Sportdes short- 
fusoid or oblong, yellowish, 2-3-nucleate, 7-15 (mostly 7-10) x 3- 
3*-_> microns. Found associated with Leptosphaeria alcides Sacc., 
of which it is apparently the spermogonial stage. 
“ Insects Injurious to Staple Crops” is the title of an admir- 
able compilation by Prof. E. Dwight Sanderson, of the Delaware 
Agr. Exp. Station, who has brought together the most essential 
matter regarding our principal farm crop pests in the group of 
insects. The work will be a welcome one to students and 
teachers, though it necessarily occupies a somewhat limited field, 
so far as school instruction goes. Its greatest service should be, 
as it is evidently intended to be, in enabling the progressive 
farmer to get the benefit of the immense advance made in methods 
of treating injurious insects which has resulted from the work of 
economic entomologists during the last decade or two. — H. O.
