The species thus far recognized from the eastern United States 

 may be separated by the following key : 



1 (2). Intermediate tarsi subequal to or but little longer than posterior, 



joints 2 and 3 subequal; second joint of hind tarsi longer than 

 third V. stagnalis Burm., Heid., Bueno 



2 (i). Intermediate tarsi much longer than posterior, joint 2 much 



longer than 3; joint 2 of hind tarsi shorter than 3; (first joint 

 of antennae nearly one and a half times as long as second). 



V. australis n. sp. 



Velia stagnalis Burmeister, 1835, Handbuch, II : 212. — So far, this spe- 

 cies has been taken only in the apterous form. Before me are two speci- 

 mens, one from Washington, D. C. (Heidemann), and the other from 

 Raleigh, N. C. (C. S. Brimley). Burmeister records two specimens from 

 near Philadelphia, and it is also stated to be found in Cuba. I know of 

 na life history notes or details of habitat. 



Velia australis n. sp. — Head triangularly obtusely produced with a me- 

 dian impressed line; eyes globose, a Httle 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, sub- 

 equal 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 f oveate punctures ; lateral angles prominent. 



Hemelytra (or tegmina). narrower and slightly shorter than abdomen, 

 with sHght distinction of texture between corium 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 metapleur^ 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), an interrupted 

 streak on the connexival suture beneath ; luteous : antennas, 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- 

 brane smoky with three white spots at apex, the central one cordate and 

 deeply emarginate, the two lateral ones irregularly rounded and nearer the 

 apex of the membrane. Veins concolorous.
