compartment of the front and a shorter one on the cheeks fulvous, carina; 

 white; basal fova; of the vertex pale, base of the scutellum, disc of the pleu- 

 ral pieces, some marks on the base of the vertex in the male, and the claws, 

 blackish. The black on the base of the scutellum is mostly covered by the 

 pronotum but on either side it is extended backward as a black line next to 

 the patagia. Tergum black, the broad margins and a transverse band near 

 the apex whitish in the male, fulvous in the female. Elytra whitish, ner- 

 vures concolorous, the marginal heavy and brown around the apex; the 

 inner apical areoles with a faint longitudinal fuscous cloud. Tips of the 

 last segment of the connexivum black in the female. Length, male 3^, 

 female 4 m. m. 



The genital characters of the male are similar to those of pellucida; 

 stiles quite broad, widely divergent, their apex rounded and a little twisted. 

 All the pieces black except the edge of the anal tube.

LIBURNIA CONSIMILIS, n. sp. 



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



Form and aspect of L. pellucida. Black; all the carina;, the broad pos- 

 terior margin of the pronotum, feet, mostly, and the narrow margins of the 

 abdominal and pleural pieces, white; elytra faintly fuliginous, nervures 

 brown. Length 4 m. m. 



Macropterous male: Compared with the male of pellucida the vertex 

 is a little longer, the basal fova? distinctly longer, the apical smaller and the 

 posterior margin of the vertex more distinctly emarginate. The front is 

 proportionately a little broader than in that species, the lateral carina; are 

 more distinctly arcuated, the apical joint of the antenna; is smaller, the 

 pronotum is shorter, the hind edge a little more deeply excavated and the 

 apex of the scutellum is broader and shorter. 



Color black ; carinas of the head and pronotum narrowly white, teguk-s 

 and broad margin of the pronotum white; edge of the scutellum touched 

 with fulvous on its middle; connexivum and narrow margin of the ventral 

 segments and pleural pieces whitish; legs brown, base and apex of the 

 femora tip of the tibiae and the tarsi soiled white, the latter tipped with 

 black. Elytra extending one half their length beyond the abdomen, very 

 faintly smoky, nervures brown; wings white, nervures brown. 



Genital segment of the male long; aperture similar in form to that of 

 pellucida but smaller with the styles narrower and less widely spreading, 

 ventral notch of the pygofers small. 



1 have given a comparative description of this species as best suited to 

 distinguish it from the closely allied pellucida with which it might very 

 readily be confounded, the form of the male genitalia is however very 

 different, the insect is broader and has a wider front and vertex, and the 

 male and female scarcely differ in color. The latter has the femora pale 

 lineated with brown and the elytra are darker with stronger nervures.
