Show 1894.] HEMIPTERA-HETEROPTERA OF GRENADA. 215 mesopleura, border of metapleura, bands on ventral segments, antennae, and legs black. Length to tip of venter 2f 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 present in the collection. The others are either young specimens, or undeveloped females without indications of wings. The measurements 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 Metrobates, Uhler. In the female, however, the antennae are very much shorter than in either of the genera just mentioned. VELIID M. VELIA, Latr. VELIA STAGNALIS, Burm. Velia stagnalis, Burm. Handb. ii. p. 212. Several specimens were collected on the Mount Gay 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. BHAGOVELIA, Mayr. BHAGOVELIA ANGUSTIPES, sp. 110V. In form similar to R. obesa, Uhler; black, opaque, closely pubescent.

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 tbe tip a little bent and almost acute; the humeral angles a little ridged, the lateral margins feebly acute, a little sinuated.
