Biology of Staphylinidae 243 
the pitts root maggot (Phorbia brassicae Bouche), down to 
the present day there has been a feeling that certain of the 
staphylinids approached a parasitic behavior. Following Sprague’s 
report in 1870, most of the authors who discuss the cabbage 
some species of Baryodma as a possible parasite. 
A number of these reports are as follows: Barnard (80:199) 
reports Baryodma anthomyiae (Sprague); Lintner (82:188) 
quotes Sprague (70:300) and Barnard (80:199); Fletcher 
(86 :188) ; Fletcher (91:164); Fletcher (02:7); Slingerland 
(94 :517- 519) q uotes from Spragu ue, Barnard and cher ; 
Washburn (08 206) reports B. nitida Grav.; Lowry (15:146) 
quotes Sprague; Schoene (16:147-150) reports B. bipustulata 
L.; Gibson and Treherne (16: 52) reports B. ontarionis Casey ; 
Eyer (22:10) cites no definite species; Du Porte (13:7); 
Paillot (14:?); Severin and Severin (15:?); Smith (22:7); 
Miles (24:?); Triotzki (25:?); and Zorin (27: ?).- (The last 
seven have not been seen by the author but are references taken 
from reviews in the Rev. of App. Ent. Ser. A). 
he taxonomy of this group of Harb is highly involved.

the genus papal A subgenus C vrei In his upple- 
ment Leng (27:24) lists peer te Sprague as a synonym of 
verna S ch is suspected of being a synonym of nitida 
Tav. ; 
According then, to the Leng Catalogue there are possibly three 
valid species (verna a entclges Casey and nitida Grav.) in 
North America which are known to be parasitic on the cabbage 
root maggot. Nitida is feniee 3 in paoee and it is probably an 
imported species in this country, coming to us in shipments of 
root stocks. 
Wadsworth (15) reared a number of staphylinids from the 
puparia of the cabbage root maggot and made Siren tase on
