4G PSYCHE [June 
Ploiariodes errabunda Say. 
Hem. N. Harm. 34, 1832. 
maculata Hald., Proc. Acad. Phil. III, 151, 1847 (Ploiaria). 
I have this species from Falls Church, Va., and Plummer’s Island, Md., in July, 
August, and September. It has usually been taken on logs of wood, but once I 
found two specimens on the bark of a live tulip tree, and one was taken at light. 
There is some variation in the depth of coloration, enough to easily cover Haldeman’s 
form. 
Ploiariodes tuberculata n. sp. 
Brown, the pronotum blackish, the legs and antenne pale, annulate with black 
on the basal parts, the wings brown or blackish, reticulate with whitish. In general 
it is similar to P. errabunda, but the wings are more evenly marked, the femur I is 
rather longer, and it is a slightly larger insect, but the most prominent difference is 
the black conical tubercle near the posterior border of the mesothorax; the posterior 
lateral corners of the mesothorax are also more prominent than in P. errabunda. 
Length 5.2 mm. 
From Sea Cliff, N. Y., and Falls Church, Va., in August and September. 
Ploiariodes californica n. sp. 
Pale brown, mesonotum with two whitish stripes, pronotum with a black line 
each side; legs and antennee banded. Wings mottled as in the other species, more 
heavily and evenly brown than in P. errabunda; the middle band on tibia I is broader 
than in P. errabunda. It differs also from P. errabunda in that the spine at the base 
of the scutellum is shorter than the one at its apex. 
Lengtb 5 mm. 
From Stanford Uniy., Calif. Sept. (Doane). 
BARCE. 
Stal, Hem. Afric. II], 163, 1865. 
Three species are fairly common in the Eastern U. S., one specimen of another 
species I have from ‘Texas, and doubtless others will be found in the West. 
1. Femora il and IIT with several bands; median carina of mesothorax not distinct. 
B. annulipes. 
Femora unbanded, or only one near apex, median carina of mesothorax distinct. 
2.
