posterior angles obliquely truncated. Hemelytra nearly three 

 times as long as the width, translucent, the posterior margin 

 straight : discoidal veins long, the middle one simple, the inner one 

 forked behind the middle, the outer one twice forked next the 

 membrane, the Aeins continuing this line across are oblique, and 

 then straight in regular succession to the posterior margin ; cells 

 of membrane mostly quadrangular, longer than wide. Posterior 

 tibiae with three spines behind the tip. 



Tangidia alteenata, sp. nov. 



Pale fidvous, polished, broad, moderately flat. Head lined 

 around the margins \rith white, and the triangle and oval reliefs 

 of the sides of vertex also white; front pale yellow, the upper 

 submargin ])lack ; eyes placed horizontally, long, oval, brown ; 

 rostrum extending to the middle coxae. Eaised margins and 

 oarinate line of both pro- and mesonotum whitish. Costal areoie 

 long, wide, terminating in an acute pterostigma of dark brown 

 colour ; veins pale testaceous, interrupted by dark brown, the 

 brown of the membrane most conspicuous on the apical margin and 

 cross-veins ; wings a little tinged with fulvous at base, the veins 

 darker at tip. Sides of thorax streaked \dth pale brown, and a 

 darker line runs back from behind the eye. Legs pale yellow ; 

 knees a little infuscated, the tips of spines black, and a short dark 

 streak appears beneath the posterior knee. Venter greenish, 

 broadly bordered with red, segments of the tergum obscurely 

 banded with rufous and bordered with pale yellow. 



Length to tip of abdomen 4 mm. ; width between wing-covers 

 1| mm. ; width of expanded wings 10 mm. 



Only one specimen of this neat insect was secured. 



BOTHEIOCERA SIGNOEETI, Stal. 



vSeven or eight specimens of the variety of this species, with the 

 pale spot occupying most of the basal tliird of the corium, were 

 collected at various localities on the island. 



BoTHRiocERA BicoENis, Fabr. 



Seven specimens of this form were collected at different points 

 on the island. They differ in minor details of marking from 

 Brazilian and North-American specimens. This species is found 

 also in Texas, Floi-ida, North Carolina, Maryland, and New Jersey. 

 In the last two States it is found in midsummer upon grass-like 

 plants in the cranberry marshes. 



BOTHBIOCEEA UNDATA, Eabr. 



Ten specimens of several states of immature colouring are 

 present in the collection from St. Vincent. I find no structural 

 differences to separate these from the foregoing species ; and 

 several specimens are so immature as not to have developed a 

 pattern of marking.
