1894.] HEMIPTERA-HETEROPTEEA OE GEEKADA. 215' 



mesopleura, border of metapleura, bands on ventral segments, 

 antennae, 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 A;\ithout indications of wings. The measure- 

 ments are taken only from the winged male specimen used for 

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

 as in Mheumatobates, Bergr., and Metrobatcs, Uhler. In the female, 

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

 genera just mentioned.

Several specimens were collected on the Mount Gay estate, 

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

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

 Other specimens were secm-ed 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.
