inferior surface beyond the basal third in male, only three or four 
spines beyond the middle in female; tibia with short apical spur in 
both sexes, also with short teeth on inferior surface; tarsal segments 
II and IIT subequal, prolonged backwards into a sharp spine in both 
SOXeS. 
Macroprerous FoRM: Pronotum unicarinate; hemelytra slightly 
longer than abdomen, with dark fuscous veins, clothed basally with 
silvery hairs, the cells dark fuscous. 
This stridulating species is known largely from the type series, 
netted under the underhanging ledge of a narrow stream, in the 
western part of Trinidad, British West Indies. Other specimens are 
also at hand from Venezuela. 
The stridulatory organs (pl. 1) and male parameres (pl. 3,a) separate 
it from all other members of the subgenus occurring in the West 
Indies, Mexico, and Central America. A male paratype is illustrated.

BrRaAcHYPTEROUS FORM: Elongate, narrow, fuscous, with a large 
patch of appressed silvery hairs on each side of forelobe of pronotum ; 
body beneath darker; wing pads small, clothed with silvery white

Antennal measurements: segment I, 1.20 mm.; IT, 0.95 mm.; III, 
0.65mm.; 1V,0.55 mm. Pronotum with median carina, more convex 
in macropterous than in brachypterous form; connexivum produced 
backwards apically into a sharp spine, this spine longer in male than 
female; abdominal pleura with a pair (one on each side) of median 
vertical sulci on segments IT through IV; male parameres as in pl. 
3,a; hind trochanter usually armed with a long spine in male, unarmed 
in female; hind femur slightly swollen, armed beneath with two rows 
of moderately large spines, the front row with a larger spine at apical 
third; tibia beneath with two long rows of dark, closely set teeth, 
also with a partial third row on basal third; female femur shghtly 
less incrassate than in male, armature absent on basal third, other- 
wise with armature of both femur and tibia nearly same as in male. 
Macroprerous ForM: Front lobe of pronotum with silver patches; 
hemelytron dark fuscous, with yellowish and silvery hairs on corium; 
membrane brownish fuscous with a large subapical yellowish lunar
