1894.] HEMIPTEBA-HETEROPTERA OE GRENADA. 215 



rnesopleura, border of metapleura, bands on ventral segments, 

 antenna?, and legs black. 



Length to tip of venter 2^ mm., to tip of membrane 3| mm. ; 

 width of pronotum 1 mm. 



South of Grenville, windward side of island, August 4, on 

 stagnant water. Only one specimen of the winged form is pre- 

 sent in the collection. The others are either young specimens, or 

 undeveloped females without indications of wings. The measure- 

 ments are taken only from the winged male specimen used for 

 description. The females have the simple antennae and hind legs, 

 as in Rheumatobates, Bergr., and MetrobaUs, Uhler. In the female, 

 however, the antennas are very much shorter than in either of the 

 genera just mentioned.

Several specimens were collected on the Mount Gray estate, 

 late in August, on the surface of shady pools of small streams, on 

 the grass growing in the water, and also gliding over the surface. 

 Other specimens were secured about the same time and early in 

 September at Woburn and Mount Maitland. The larval form was 

 found at Woburn, August 30, on a sluggish stream near the sea- 

 level. These specimens are more clearly marked with the silvery 

 white streak at base of corium, and with similarly coloured dots 

 on the connexivum and spots on the membrane, than is usual in 

 specimens from the southern United States, Cuba, and Mexico. 

 The large silvery area near the end of the tergum is evanescent, 

 and not present in weather-beaten individuals.

In form similar to R. obesa, Uhler ; black, opaque, closely pubes- 

 cent. Head including the eyes a little wider than the front of the 

 pronotum, the middle line elevated into a callosity which runs 

 back, tapering, to near the occiput ; eyes prominent, coarsely 

 granulated ; antennae black, set with remote, erect bristles, with 

 the basal joint curved, yellow at base, and the second and third 

 joints shorter, subequal in length ; rostrum piceous black, extend- 

 ing to behind the anterior coxae. Pronotum moderately convex, 

 yellow back of the head, trapezoidal in front of the humeral angles, 

 triangular and a little shorter behind them, with the posterior 

 margin flat, a little reflexed on the edge, and with the tip a little 

 bent and almost acute ; the humeral angles a little ridged, the 

 lateral margins feebly acute, a little sinuated. Underside plum- 

 beous. Scutellum concealed. Legs hairy ; the coxae, trochanters,
