Eucanthus acuminatus Fab. Taken near Sandusky on San- 
dusky River a number of specimens being secured from an old 
log and stump where they seemed to congregate. 
Pediopsis basalis VanD. Taken at Arcanum on cottonwood 
by Mr. Swezey. 
Deltocephalus configuratus Uhl. Collected at Ashtabula in 
August. 
Goniagnathus palmer! VanU. One specimen of this inter- 
esting little species taken at Columbus. 
Typhlocyba rubroscuta Gill. Collected at Columbus. 
Typhlocyba crevecouri Gill. Columbus, collected by Mr. J. G. 
Sanders. The specimens agree perfectly with descriptions except 
that there is a broad black band covering segments 1 to 5 of the 
abdomen both above and below not mentioned by Gillette who 
says “all beneath pinkish yellow.” 
Livia maculipennis Fitch. This interesting little Psyllid was 
discovered at Ashtabula while collecting near the city with Mr. 
E. V. Louth. Adults were first swept from the heads of a Juncus 
identified by Mr. Louth as Juncus acuminatus, closer examina- 
tion of the heads revealed nymphs enclosed in the swollen glumes 
in many instances occurring in large numbers so the heads were 
fully packed. The relation of these nymphs to the adults that 
had been swept was at once suspected and definitely proven later 
by breeding.

front uniformly dark brown, minutely dotted with yellow, color 
olivaceous brown above and below, elytra with minute roundish 
white spots. Length female, 4.o-4.7d mm. Male 4.

angled, front narrow tapering gradually to ajiex, clavus longer 
than broad, widening slightly at apex, pronotum about as long 
as vertex, rounded anteriorly nearly truncate behind. Elytra 
scarcelv hyaline, a series of reflexed cross veinlets in the costal 
area.

and with minute yellowish lines. Front dark fuscous with yel- 
lowish arc near the vertex and numerous minute yellowish dots, 
larger on the lorse ; scutellum and elytra coppery fuscous with
