na? stout, the two basal joints about equal in length. Pronotum short, 

 anterior edge straight between the eyes, posterior very feebly excavated, 

 lateral carina; following the contour of the eyes. Scutellum short. Elytra 

 in brachypterous form with strong reticulated nervures. Anterior and 

 intermediate feet with the posterior coxa; strongly flattened, the femora 

 deeply sulcate within. Posterior tibiae bispinose. 



PHYLLODINUS NERVATA, n. sp. 

 Eurysa nervata, Van Duzee, Bui. Buf. Soc. Nat. Sci., V, p. igi, 1S94. 



Form oblong, broad and short. Head wider than the pronotum, vertex 

 nearly square, a little transverse, the edges nearly rectilinear, the anterior 

 fova long-triangular, reaching over the rounded anterior edge of the head. 

 Front oblong, a little expanded opposite the lower angle of the eyes; middle 

 keel distinct for its whole length on the front but obsolete on the base of 

 the clypeus. Pronotum shorter than the vertex, the fore and hind margins 

 nearly straight and parallel, lateral carina? much curved. Sides of the large 

 scutellum concave, the lateral carinas straight and oblique; near theb asal 

 angles. Elytra short and broad, covering the fifth abdominal segment, 

 rounded behind. Pygofers of the male compressed laterally, the aperture 

 narrow, forming a rounded pocket below to enclose the short slender curved 

 stiles, which are approximated but do not quite touch at their tips. Wall 

 of the anal aperture square and produced on the ventral aspect, the lower 

 angles acute and nearly touching one another. Femora and tibia? of the 

 anterior and intermediate feet thin and broadly expanded. Length 2% 

 to 3 m. m. 



Color piceous brown. Vertex pale, a short anterior median line and a 

 row of dots on either side brown ; disc of the pronotum and its carina? pale ; 

 scutellum pale with the basal angles and a double median line brown. 

 Elytra subhyaline, smoky, with numerous heavy ramous white nervures. 

 Front blackish with the carina? and a double row of dots on either side pale. 

 Carina? of the clypeus in part, rostrum, excepting its tip, edges of the femora, 

 and tips of the tibia?, some marks on the pleural pieces, sternum and coxa? 

 below, and the apical joint of the antenna?, pale. Disc of the tergum in the 

 females tinged with reddish with a more or less complete double row of 

 pale spots on either side. Tip of the genital pieces and the oblong plates 

 at the ba<-e of the oviduct in the females whitish. Deflexed sides of the 

 pronotum expanded into a large white plate at the base of the elytra. 



New York and Canada. Not uncommon near Buffalo on damp weedy 

 meadows in June. Also taken in Welland Co. Out. and at Muskoka Lake 

 in July. This is our largest northern Delphacid. Its square form and 

 brown color with the strongly ramously veined elytra will distinguish it. 



LACCOCERA, new genus. 



Allied to Delphacinus and Eurysa. Head large, a little wider than the 

 pronotum. Vertex nearly square or somewhat five-sided, a little surpass- 

 ing the eyes before. Front broad, six-sided, distinctly angled between the 

 eyes; apex but little narrower than the base; passage to the front strongly
