Eucanthus acuminatus Fab. Taken near Sandusky on San- 

 duskv River a number of specimens being secured from an old 

 log and sttimp 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 palmeri VanD. 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. 



Platymetopius obscurus n. sp. Head moderately produced, 

 front uniformly dark brown, minutely dotted with vellow, color 

 olivaceous brown above and below, elytra with minute roundish 

 white spots. Length female, 4.5— t. 75 mm. Male 4. 



Vertex about one and one-half times as long as broad, acutely 

 angled, front narrow tapering gradually to apex, clavus longer 

 than broad, widening slightly at apex, pronotum about as long 

 as vertex, rounded anteriorly nearly truncate behind. Elytra 

 scarcely hyaline, a series of reflexed cross vemlets in the costal 

 area. 



Color, dark olivaceous brown, vertex with pair of yellow epcts 

 and with minvite yellowish lines. Front dark fuscous with yel- 

 lowish arc near the vertex and numerous minute yellowish dots, 

 larger on the lorae; scutellum and elytra copperv fuscotis with 

 indistinct longitudinal lines — five on pronotum, two on scutellum, 

 elytra with rounded white dots on the apical and ante-apical 

 cells and in basal portion of corium. Ramose lines and reflexed 

 costal veinlets blackish.

 behind. Male valve nearly as long as broad, obtusely angled 

 behind ; plates elongate triangular, reaching ti]) of pygofer.
