tate line. Scutellum strongly elevated at base, a little rugulose, deeply 
depressed on the middle and posteriorly. Legs and coxe bright yellow, 
the femora faintly tinged with brown, and the tips of tibiz and tarsi 
piceous. Venter black, minutely pubescent, the apex a little tinged with 
piceous. Corium and membrane coalescing, both coriaceous, long and 
narrow, convexly arched, deflexed on the sides, the part representing the 
membrane running off to an oblique rounded tip, with the nervures 
almost effaced. 
“Length to tip of venter, 44% mm.; to end of hemelytra, 4% mm. 
Width of base of pronotum, 114 mm. One specimen from the vicinity of 
the Saskatchewan river, collected by Robert Kennicott. 
“This is surely cnly the dimorph of the form with perfectly developed 
membrane. In the S. anthracina parallel forms occur, the one with a 
distinct membrane and the other with the membrane thickened and almost 
as coriaceous as the corium proper; also, the bounding nervure is faint 
and almost obliterated, almost the same as in this form of S. crassi- 
corns. ‘ 
“Tn the present specimen, the nervules of the membrane are very in- 
distinct.” —Uhler. 
Genus SALDOIDA Osborn 1901. 
“Head narrower, eyes nearer together than in Salda, ocelli approxi- 
mate, frontal ridge weak, becoming obsolete at base of tylus, buccule en- 
larged; antennze with the two distal joints incrassate, rostrum as in Salda, 
basal joints very thick, second elongate, terminal very slender. Prothorax 
bearing two very prominent conical tubercles on anterior lobe, which is 
narrow, cylindrical, not carinate anteriorly; posterior lobe short, carinate 
laterally, widening rapidly to humeri.” 
Saldoida slossoni Osborn 1901. 
Osborn, Can. Ent., XXXIIJ, p. 181, 1901. 
“Hind angle of pronotum obtuse, not produced into a sharp angle or 
horn. Light brown, marked with reddish-yellow and black, face tes- 
taceous. Female, length to tip of elytra, 3 mm.; width at humeri, scarcely 
1 mm. 
“Head obtusely triangular, subcordate, inclined, the part in front of 
the eyes nearly equal to eyes in length, very sparsely set with erect hairs; 
eyes large; vertex narrow, less than width of eye; ocelli minute, set close 
together; antenne long, joint two longer than one, equal to three, three 
much swollen, four equalling one in length, and about half as thick as 
three; rostrum reaching to apex of hind coxe. Prothorax with two very 
large, erect, conical tubercles occupying the upper surface of the anterior 
lobe; posterior lobe short, much widened behind, concavely emarginate, 
the lateral angles obtusely angulate. Scutellum large, anterior border 
convex, surface polished, minutely punctate, apex inflated, highly polished. 
Elytral membrane subhyaline, with four cells and a wide margin, wings © 
reaching to tip of elytra, milky hyaline. ~ 
“Color: Vertex black, with margins next eyes red-brown; face and 
rostrum testaceous, antenne, basal two-thirds of second joint and all of— 
third fuscous, apex of one and two whitish, fourth yellowish brown, 
darker at base and minute tip; prothoracic tubercles red-brown, posterior 
lobe yellowish brown, anterior margin and band back of the tubercles 
black; scutellum black, apex piceous. brown; elytra brown, claval suture 
and apical margin of corium black, corium with two triangular whitish 
spots, the bases of which merge into the hyaline costa, membrane with 
fuscous base and hyaline apex; beneath black, with throat, pleural pieces, 
cox and legs yellowish brown, darker on disc of coxe, apical portion of - 
femora and base of tibize, the apex of tibize and last joint of tarsus, 
fuscous; margin of last ventral segment whitish. 
“Described from one specimen (female) from Florida, collected by 
Mrs. Annie Trumbull Slosson, to whom it is most respectfully dedicated.”
