black longitudinal fascia on both sides of lateral, longitudinal, marginal 

 furrow; hemielytra hyaline, apical tubercle of scutellum and embolium 

 black; the latter yellow at base and surrounded by a small fuscous 

 area at external apical angle of corium and apex of embolium; a spot 

 on internal portion of corium near claval commissure slightly above 

 apex of clavus, another on internal basal angle of cuneus, and apex of 

 cuneus fuscous; membrane infumate with a median apical fuscous 

 spot not bordering external margin, transversal portion of vein of 

 membrane reddish; underside brownish, legs pale yellow, posterior 

 femora with a subapical fuscous band ; ostiolar peritreme and extreme 

 base of coxae black to brownish. 



Head strongly pointed, vertex carinate; pronotum with a deep 

 lateral, marginal, longitudinal furrow, callused area sub trapezoidal, 

 distinctly set off from collar, disc constricted at middle without 

 median longitudinal carina, which is present only at posterior portion 

 of calli, finely punctate and faintly crested, posterior margin bi- 

 concave; scutellum long, acute at apex, terminating in a compressed 

 tubercle; hemielytra hyaline, clavus ^vith minute pubescence only 

 over claval vein, embolium widened apically where a conical tubercle 

 may be seen, cuneus as long as wide at base, rounded internally on 

 basal two-thirds; membrane finely pilose; rostrum reaching the apex 

 of anterior coxae; eyes pilose. 



Male genitalia: Aedeagus (fig. 123, e) simple, without teeth or other 

 chitinized structures internally. Left clasper (fig. 123,6) pointed 

 apically with a dilated base bearing a few setae. Left clasper small, 

 simple, pointed apically. 



Geographical distribution: Central and South America. 



This species is distinguished from T. maculata Usinger, 1935, by 

 the presence of a tubercle on the apex of the scutellum and on each 

 embolium, by the much less crested pronotal surface, and especially 

 by the absence of brownish spots at the base of the hairs on the 

 hemielytra. 



Termatophylidea opaca, new species 



Plate 31, a 



Characterized by its color, roundish hemielytra with opaque surface, 

 and eyes set close to pronotum.
