1894.] HEMIPTERA-HETEEOPTEEA OP GEENADA. 219 



2. MiCEOTELIA EOBUSTA, Sp. HOV. 



Shorter and comparatively more robust than M. modesia. Colours 

 about the same, except that there is an absence of pale colour from 

 the venter and no j^ellow border on the connexivum. The head 

 is immersed nearly up to the eyes in the pronotum ; the eyes are 

 bordered internally with prostrate white pubescence ; the front of 

 the pronotum is shorter and less contracted, densely covered with 

 white pubescence, which is laid upon a faintly yellow band ; the 

 pleural pieces are not broadly bordered with testaceous, and the 

 posterior femora are only a little longer than the middle ones ; the 

 last joint of antennae more than one third longer than the third 

 joint. The hemelytra are smoke-brown, often pale, with two white 

 diagonal streaks at base, pale spaces in the areoles, and a white 

 pyriform spot in the apical areole ; the costal area is almost linear, 

 deflexed, pale, and marked with a row of remote brown dots. 



Length to tip of venter 2 mm. ; width of pronotum g mm. 



A few specimens were collected at Woburn and Beaulieu, 

 August 25, at an altitude of 700 feet above the sea, on the surface 

 of a stagnant pond ; another specimen was taken on the Mount 

 Gay estate, in September. 



3. MiCEOTELIA MAEGEfATA, Uhler. 



Microvelia marginata, Uhler, P. Z. S. 1893, p. 719. 



Several specimens were secured on the Grand Etang, August 9, 

 at an elevation of 1900 feet above the sea, on pools of water in a 

 swampy forest. 



This beautiful little species has a very extended distribution, as it 

 is now known to occur in Trinidad, St. Vincent, Central America, 

 Mexico, Cuba, and in the United States, from Florida to northern 

 New Jersey. In Maryland it lives on the quiet pools beside 

 streams of water near the cities of Baltimoi-e and Washington.

 throat and cheeks testaceous ; middle of vertex oblong-ovate, pro- 

 minently elevated ; rostrum pale testaceous, piceous towards the 

 tip, reaching to the middle coxse; antennae slender, pale rufo- 

 piceous, a little darker at ends of the joints, the base of first and 

 second joints testaceous, second joint shortest, third longest, about 

 one and a half times as long as the second, the fourth a little 

 shorter than the third. Pronotum a little longer than wide, steeply 

 sloping anteriorly, velvety, powdered with pale grey, with a slender
