NORTH AMERICAN HOMOPTEKA. 305 



large and thick, very slightly exceeded by the oviduct, the sides of the latter 

 and a spot on the apex of the last ventral segment black. 



New York and Iowa. Described from one male and four female 

 examples taken at Lancaster, N. Y., Sept. 3, 1888. These were 

 swept from grass and weeds near the borders of a low swampy wood. 

 I have also had the pleasure of examining an Iowa specimen re- 

 ceived from Prof. Herbert Osborn, the well-known entomologist, to 

 whom I dedicate this large sj^ecies in recognition of the kind and 

 ready response always received to any appeal for assistance or mate- 

 rial from him. 



7. neltoceplialiis cinorosiis n. sp.— Form and size o( D. ilehheimeri 

 nearly ; grayish yellow, marked with fulvous brown ; elytra cinereous, the areoles 

 mostly edged with fuscous. Length 3 — 3.5 mm. 



Venter flat; length on the middle nearly twice that next the eye; disc fulvous- 

 brown, with a pale longitudinal vitta including the black impressed line; ante- 

 rior submargin with a dark brown broken line abbreviated at the pale polished 

 tip and touching the ocelli ; front with about nine brown arcs coalescing at the 

 apex and on either side of the pale median line, sutures black; clypeus moder- 

 ately narrowed apically, its sides straight ; disc of the prouotum dusky with five 

 pale longitudinal lines; scutellum brown within the basal angles and on either 

 side of the apical field. Elytra cinereous, nervures paler, marked with white on 

 the transverse veinlets, the areoles mostly bordered with fuscous ; disc of the 

 venter and connexivum, two bands on the anterior and intermediate femora, 

 and a series of points at the base of the tiliial spines, dark brown ; terguni black, 

 broadly edged with yellow. Wings whitish hyaline. 



Genital characters: %. — Valve large, triangular, obtuse; plates hardly twice 

 the length of the valve, ovate-lanceolate, obtuse and moderately divergent at 

 apex ; pygofers black, considerably longer than the plates and closely beset with 

 stiff white bristles; disc of the valve and plates blackish. Female: Apex of 

 the last ventral segment with a minute notch between two short truncated teeth, 

 either side of which the margin retreats to the rounded angles, the apical teeth 

 and a cloud behind them black ; pygofers stout, nearly- equaling the blackish 

 oviduct. 



California. Described from one male and four female examples 

 received from Mr. D. W. Coquillett (No. 267), under Mr. Uhler'.-^ 

 MS. name here adoj)ted. This little gvay form varies somewhat in 

 the extent of its dark markings. It bears a marked resemblance to 

 D. liiimieus Say, but it is smaller, with a longer vertex, and wants 

 the six black j)oints so conspicuous in that species. It is still nearer 

 D. coafiguratus Uhler, but its more slender form and the characters 

 of the genitalia will readily distinguish it. A closely related Euro- 

 pean species is D. breviceps KirschI). 



8. DeltoC(>|>lialli»i !«igiiatili'OiiM n. sp.— Allied to D. Sayi in form and 

 ornamentation, but smaller, with a shorter vertex. Length 3 — 3.5 mm.
