very slightly thickened, armed beneath with a row of very fine 

 teeth; the tibire especially clothed with stiff hairs. Hemelytra 

 long and rather narrow, the costal vein stout, clothed at base with 

 stiff bristles. Tenter smooth, plumbeous, with the genital pieces 

 and the middle of the border of the apical segment orange.

Numerous specimens were obtained at Balthazar, August 7, at 

 an altitude of 250 feet on running water ; also on the Mount Gay 

 estate, April 5, at the same altitude ; and at Mount Maitland, 

 August 20-25, at an altitude of 150 feet, on the surface of a 

 stream of spring-water. 



2. Ehagovelia elegaxs, sp. nov. 



Larger and more robust than R. anf/ustipes. Fuscous or dark 

 rusty brown, hairy. The head short, across the eyes hardly wider 

 than the front of pronotum, the callous ridge between the eyes not 

 tapering posteriorly, almost touching the pronotum ( $ ) ; the eyes 

 wider apart, with the space between them broad, coarseiy granulated, 

 and destitute of a callous ridge ( c? ) ; the cheeks and most of the 

 face yellow ; antennae of medium thickness, remotely set with long 

 bristles, with the basal joint yellow at base, about one third longer 

 than the second, the second a little less thick, much longer than 

 the third, the third and fourth a little more slender, both contracted 

 at base, the third with a slender tooth at tip, the fourth much 

 shorter and acute on the apex ; the rostrum yellow, piceous at tip, 

 reaching behind the anterior coxae. Pronotum stout, convex, 

 coarsely transversely wrinkled, bordered all round with yellow, 

 this colour covering the anterior lobe as a broad band and extend- 

 ing down over the pleura ; the propleura constituting a thick and 

 broad callous smooth segment to carry the front legs, the surface 

 behind this punctate in a curved line ; middle line obsoletely cari- 

 nated, the posterior margin almost equilaterally triangular, with the 

 edge recurved and the space before the tip usually depressed ; the 

 humeral angle bluntly reflexed, obtuse, cut apart from the side 

 below by an incised line ; pleura and sternum yellow, with piceous 

 streaks running down upon the coxae. Legs stout, pubescent, 

 dark brown, with the coxal plates mostly yellow ; the posterior 

 femora thick, clavate, tinged with bronze, polished, paler beneath, 

 and armed there with about seven, chiefly long, teeth, of which the 

 two inner ones are longer and thicker. Hemelytra dark fuscous 

 brown, long, almost parallel-sided, and with thick prominent veins. 

 Venter yellow, sometimes dusky, polished, with a stripe of brown 

 each side running parallel with the outer margin ; the border of 

 connexivum brighter yellow, as also the genital segments. 



Length to tip of venter 4^-5 mm. ; width of pronotum 

 lf-2 mm. 



The prothorax is much shorter and more blunt on the posterior 

 margin in the unwinged individuals. 



Specimens of this form were met with at several localities. 

 At Balthazar they were taken in April, on water ; also on the
