Velia australis Bueno. 
Bueno, Bull. Brookl. Ento. Soc., vol. XI, p. 54. 
“Head triangularly obtusely produced with a median impressed line; 
eyes, globose, a little less in diameter than the distance between them. 
Antenne slender, first joint stoutest, longest, curved; second joint thinner 
than first, but stouter than third and fourth, shortest; third and fourth 
joints slender, of nearly equal thickness throughout, subequal in length; 
all pilose and setigerous. 
“Thorax faintly carinate, roundedly produced posteriorly, deeply punc- 
tured; two transverse impressions before the middle, the posterior with © 
four deep foveate punctures; lateral angles prominent. 
“Hemelytra (or tegmina) narrower and slightly shorter than abdomen, 
with slight distinction of texture between corium and membrane. , 
“Femora stout, anterior shortest, intermediate longest; all the tibiz 
are longer than the corresponding femora; intermediate tarsi longest, 
anterior shortest, first joint in all minute, second joint longest in second — 
and third pair of tarsi, third joint in first pair. 
“In the middle section of the metapeure is an obscure and scarcely dis- 
tinguishable opening, protected by three long biack upwardly curving ~ 
spines, which can be seen from above. This is a distinguishing character | 
of this species, as it is apparently not found in other American forms™ 
described and in the four or five known to me in nature. 
“Color, brown; silvery pilose: posterior connexival edges from third 
to sixth segment (only fourth to sixth visible in winged), and interrupted 
streak on the connexival suture beneath; luteous: antenne, coxe, tro- 
chanters, base of rostrum and bands on legs and bases of all femora, 
remainder of legs infuscated. Hemelytra fuliginous with sparse golden — 
pubescence on corium; corium with a narrow apical white streak; mem-_ 
the second genital segment projecting beyond like a small blunt. knob. 
Other structural characters as in the winged, except two small, triangular 
wing-pads. 4 
“Apterous form: Pronotum stout, transversely impressed about one-_ 
fourth its length from the anterior margin, two longitudinal impressions — 
from the anterior margin at the eyes meet it, producing deep fovee at 
the points of juncture; rounded truncate posteriorly with a somewhat — 
broad explanate margin. Six abdominal segments and two genital visible — 
dorsally, six ventrally (as in the winged) ; segments, except the first, of — 
nearly equal length, abdomen widest at fifth and sixth segments, with © 
two deep longitudinal lateral grooves. Connexival edges blunt, rounded; j 
genital segment quadrilateral, twice as broad as long, truncated, with 
the second genital segment projecting beyond like a small blunt knob. 
Other structural characters as in the winged, except two small, triangu-— 
lar wing-pads. 4 
“Color, brown, as in the winged, except that the specimen in hand is — 
somewhat darker i in shade. Silvery pilose, two small anterlateral patches © 
on pronotum, posterior connexival edges from second to sixth segment, 
posterior middle of third dorsal segment, broadening in fourth oa 
broadly lateral in fifth and sixth, fifth segment with a small posterior 
median patch. Milk white, vestigial wing-pads projecting beyond pos- 
terior edge of pronotum. Winged: long., 5.3 mm.; lat., 2 mm. at humeri. j 
Apterous: long., 5 mm.; lat., 1.7 mm.” \

“Of the North American species sent me by my friend Mr. Zimmer- 
man from the neighborhood of Philadelphia, I possess only wingless indi- 
viduals which are characterized by a yellow brown color, coxe yellow. 
Thorax black below. Silver spotted on sides, yellow annulated femora
