Velia australis Bueno. 



Bueno, Bull. Brookl. Euto. 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. 

 Antennae 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 cerium and membrane. 



"Femora stout, anterior shortest, intermediate longest; all the tibiae 

 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 metapeurae is an obscure and scarcely dis- 

 tinguishable opening, protected by three long black 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 : antennae, coxae, 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. 



"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 fovese 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 ; 

 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. 



"Color, brown, as in the winged, except that the specimen in hand is 

 somewhat darker in shade. Silvery pilose, two small anterlateral patches 

 on pronotum, posterior connexival edges from second to sixth seg'ment, 

 posterior middle of third dorsal segment, broadening in fourth and 

 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. 

 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, coxae yellow. 

 Thorax black below. Silver spotted on sides, yellow annulated femora
