pygofers nearly square above and below, suddenly expanded about the 

 middle at the tips of the long curved dorsal hooks; styles broad, approxi- 

 mate at base, curved outward and becoming nearly parallel and pointed 

 above. 



New Hampshire, Colorado. Described from three female examples 

 taken on Mt. Washington by Mrs. Annie Trumbull Slosson, and one pair 

 from the mountains of North West Colorado, collected by Prof. C. P. Gil- 

 lette. One of the females from Mt. Washington is more clearly marked 

 than the others ; the pronotum and scutellum are white on the middle marked 

 with black on the sides and the breast is black, otherwise it does not differ 

 from typical specimens. 



LACCOCERA ZONATUS, n. sp. 



Delphacinus zonatus, Gillette & Baker, Hemip. of Colo., p. 69, 1895. 



Brachypterous Male. Deep shining black. Front, vertex pronotum 

 and scutellum tawny yellow or whitish ; face fulvous; feet light orange, the 

 tarsi paler tipped with brown; tergum marked with a transverse band on 

 the second and third segments which may invade the base of the fourth. 

 Elytra short, truncated behind, reaching onto the second abdominal seg- 

 ment, nervures simple, strong. Apex of the ample pygofers broad below 

 with a transverse oblong excavation bounded by an incurved tooth on either 

 side. Styles approximate at base, quite widely spreading, reaching about 

 half way to the anal tube the ventral wall of which is broadly expanded and 

 produced at the outer angles into a long acute tusk-like fulvous tooth. 



Macropterous female : -Soiled yellowish white ; an oblong spot on either 

 side of the base of the scutellum, a cloud on the pleural pieces, thelineations 

 of the femora and the metanotum, brown. Tergum black, a large spot on 

 the basal disc, a row of about four pustules on either side of the middle on 

 each segment and their narrow edges pale. Elytra and wings well devel- 

 oped, vitreous with strong brown nervures. Length 2^ to 2 l A m. rn. 



In both sexes the head is very large, wider than the thorax; the eyes 

 are large overlapping the pronotum for one half their length. Vertex cut 

 squarely off behind, anteriorly extending for nearly one half its length before 

 the eyes and but little produced at the middle, the edge almost rounded 

 before, carinas distinct, forming a large triangle with its apex at the tip of 

 the head, the contained fovae strongly marked. Front broad, but little 

 narrowed at apex, the middle carina? distinct. Pronotum angularly exca- 

 vated behind for one half its length. On the front are three pairs of pus- 

 tules, one pair placed near the middle of the outer edge and smaller; a row 

 of pustules follows the curved pronotal carina? and there is another below 

 the carinated outer edge of the front, and a smaller pair occupy the outer 

 angle of the vertex. 



Colorado. Described from a single pair received from Prof. C. P. 

 Gillette. 



Since the above was written one macropterous and ten brachypterous 

 males have been received from Prof. Gillette. The former differs from the
