HUNGERFORD: AQUATIC HEMIPTERA. fir’ 
the whole surface minutely scabrous; the costal margin moderately 
arcuated, a little broadly and almost uniformly reflexed; membrane very 
long, pale dull yellowish, somewhat clouded basally, the nervules piceous, 
long and almost straight. Venter black, highly polished, minutely punc- 
tate and pubescent; the genital segment and sometimes the posterior 
edges of the others testaceous. The costal margin is testaceous in two 
specimens, in which the black of that area is much reduced and limited 
to the posterior portion, inwardly. 
“Length to tip of membrane, 44%2-544 mm. Width of base of pronotum, 
14%-1% mm.

“Specimens from Utah a half smaller than the type of polita from 
California. The costal area of corium and embolium black, while in the 
type example the entire corium, with the exception of the outermost 
point, rust-red and embolium yellow.” 
Genus LAMPRACANTHIA Reuter 1912. 
“Head (brachypterous form) as broad as base of pronotum, sub- 
vertical. Eyes strongly exserted, distant from apex of pronotum. Ros- 
trum reaching to base or apex of posterior coxe#. Pronotum shiny, 
strongly narrowed toward apex, marked by an apical stricture, poste- 
riorly terminated by a punctate impressed line. Sides sinuate, posterior 
angles prominent. Sulcus terminating callos posteriorly marked with im- 
pressed points and longitudinal wrinkles placed far behind the middle. 
Hemelytra most shiny. Abdomen of brachypterous form a little pro- 
duced, oval, convex, toward side and apex decurvate, clavus distinct, but 
corium and membrane coriaceous, merging into one. Veins wanting, or 
most obsolete. Embolium narrow deplanate. Type Salda crassicornis.”

“Still more slender than the S. anthracina, brassy-black, very highly 
polished, the upper surface with black erect pubescence. 
“Head long, anteriorly oblique, moderately long and narrow, the eyes 
very obliquely prominent; vertex a little rugulose, the front dull, some- 
what shagreened and flattened; the tylus a little prominent, cylindrical, 
highly polished; the throat concave. Antenne short, stout, the basal joint 
short, stout, black, yellow at tip; the second joint yellow, about as long 
as the third and fourth united, much more slender than either of the 
others, a very little thicker at tip; third joint much thicker, both third 
and fourth joints subfusiform, black, more conspicuously hairy, equally 
thick, much longer than the basal one, the last a little longer than the 
preceding. Rostrum reaching to the tip of the posterior coxe, rufo- 
piceous, paler at tip. Pronotum sub-campanulate, long and narrow, with 
the disk much elevated, very convex, occupying all the surface excepting 
the very narrow. posterior lobe, twice indented in the center, bounded 
behind and each side by a deep, transverse, coarsely punctate line, the 
posterior lobe consisting of only a slightly elevated linear tablet on 
the posterior margin, the margin proper moderately concave, the angles 
produced, acute; the sides deeply decurved, with the edge narrowly 
recurved, thinning out anteriorly, and bending down at the anterior end; 
the anterior margin truncate; the submargin with an impressed, punc-
