bristly towards the base ; the membrane has a pale longitudinal 

 suture throughout, with a thick vein on the middle which docs not 

 quite reach the end of the loop that is formed by the two veins 

 which run parallel to the margins and which converge on the tip ; 

 no transverse veins as in Brachymetra. In some specimens the 

 acute tip of the scutellum projects from between the metanotal 

 plates, in others it is atrophied. In two specimens the basal joint 

 of tarsi was present on one side, and not on the other. 



Hymenobates, gen. nov. 



Narrower and somewhat more elongate in form than the male 

 of Halobates pictq, H.-Schf. Head with the front of the same 

 form as in Mdrubates, Uhler. Antennae tapering in the direction 

 of the tip ; the basal joint long, fusiform, tapering narrowly 

 on the apical third, armed beneath near base with a group 

 of long spines and at the tip with a stronger spine ; the second 

 joint exceedingly short ; the third less than one half as long as the 

 first, armed with a stout triangular tooth which is followed by a 

 bundle of bristles ; the fourth shorter, curved and pointed like a 

 claw. Rostrum short and stout, extending between the anterior 

 coxae, the first and second joints exceedingly short, the third very 

 long and acutely tapering. Pronotum longer than wide, mode- 

 rately convex, ending ovately above the scutellum ; the humeral 

 angles almost obsolete, and the narrow reflexed margin sloping 

 anteriorly away from them. The anterior legs short, with the 

 tibiae thick and expanded ; the middle pair very long and slender ; 

 the posterior pair shorter, with long thick coxae ; the femora a 

 little less thick than the coxae, but curved, and like them set with 

 bristles, also with two long spines near the tip and a knob-like 

 callosity at base ; the tibia? a little longer, tapering at both euds, 

 fringed with two bundles of stiff bristles between the middle and 

 tip ; tarsi about half as long as the tibiae, very slender, tapering 

 almost to a bristle towards the tip. Hemelytra, including the 

 membrane, twice as long as the pronotum ; the corium narrow, 

 almost linear, with the costa thick and the costal cell not conspicu- 

 ous, but the discoidal cell very loug and narrow, triangular at tip 

 and sending off from the inner angle a single vein obliquely 

 across the membranous part of this organ ; a transverse suture 

 with a vein forms the boundary for the base of membrane ; the 

 clavus is minute and almost concealed, the remainder of the corium 

 is thin like a membrane; the membrane is much longer than the 

 corium, elongate-oval, with two long veins which unite at tip to 

 form a loop. The abdomen is short and subcorneal. 



Hymenobates imitator, sp. nov. 



Yellow beneath, black above, with the base of antennae, a band 

 near their tip, and a transverse spot in front of pronotum, as also 

 the coxae, yellow. Membranous part of the corium bluish, the 

 membrane smoke-brown ; the sutures, a curved line on the side of
