angled; median carina distinct, forked at the apex of the head, the lateral 

 compartments with a few large pustules. Pronotum short, deeply excava- 

 ted behind ; lateral carinse strongly curved behind the eyes, pustulate. 

 Scutellum large, distinctly constricted before the apex; lateral carinse but 

 feebly divergent posteriorly. Anterior and intermediate tibiae flattened, 

 not foliaceous expanded; hind tibia; armed, the tarsi short. 



This genus is, perhaps, nearer to Eurysa Fieb. but the carina; are more 

 distinct, the passage from the front to the vertex is more acute, the prono- 

 tum is more deeply excavated behind, and the front, vertex and sides of the 

 pronotum and abdomen are ornamented with large excavated pustules. It 

 differs from Phyllodinus in the simple anterior and intermediate tibite, the 

 form of the front, the more deeply excavated hind edge of the pronotum, 

 the smaller antennae with shorter basal joint, and the pustulated ornamenta- 

 tion which recalls Achorotile. Laccocera obesa is hardly characteristic of 

 this genus and may not belong here. Laccocera vittipennis is the type. 



LACCOCERA VITTIPENNIS, n. sp. 

 Delphacinus, Gillette & Baker, Hemip. of Colo., p. 69, 1S95. 



Head a little broader than the pronotum, blunt before; vertex nearly 

 square, very slightly angled before, the hind edge rectilinear between the 

 eyes ; apical fovae oblong, rounded before and behind. Front parallel above, 

 tapering rapidly below ; median carina strong and distinct throughout, each 

 compartment with about seven pustules, two near the apex, two at base, 

 and three smaller ones along the outer ma'"gin above the middle. Prono- 

 tum shorter than the vertex ; deeply and angularly excavated behind, lateral 

 carinae strongly curved, extending over onto the deflected sides and marked 

 by a row of small pustules. Scutellum large, lateral carinae but slightly 

 divergent. Length 4 m. m. 



Color; Head pale yellowish ; cheeks, clypeus and outer margins of the 

 front, black, carinse and pustules pale; outer apical angles of the vertex 

 with a row of shallow pustules which contain each a black dot. Pronotum 

 whitish, with a dusky cloud below the eye divided by the lateral carina. 

 Scutellum bright fulvous, outer compartments black, edged behind with 

 fulvous; the median carina sometimes pale. Elytra much exceeding the 

 abdomen in length ; whitish vitreus with a broad smoky vitta on either mar- 

 gin at apex, the inner prolonged as a fainter stripe along the sutural margin 

 of the corium to the base; nervures slender, brown. Wings white with 

 brown nervures. Breast yellowish ; coxse and legs black, edges of the 

 femora and the anterior and intermediate tibise, the basal joint of the hind 

 tarsi and the posterior tibise yellow. Abdomen black, inner margins of the 

 plates of the female whitish, edge of the oviduct and disc of the pygofers 

 fulvous. The front is sometimes blackish to the base, and the pleural 

 pieces may be more or less invaded with black; antennae black. 



The male has the head and pronotum soiled whitish with the clypeus 

 and apex of the front blackish; antennae pale; cheeks and legs fulvous; 

 coxae and disc of the pleural pieces black. Elytra smoky at base becoming 

 vitreous toward the apex with strong brown nervures. Aperture of the
