HEMIPTERA-HETEROPTERA. 307 
I have excluded from the synonymy the identification of Dallas (List Hem. ii. 
p. 381. 1, t. 12. f. 3), as the specimens in the British Museum apparently belong to a 
darker species with more serrated pronotal margins. Our Panama specimens, however, 
agree well with Perty’s figure. 
2. Bardistus formidabilis, n. sp. (Tab. XXXIII. fig. 9.) 
Pale brownish-ochraceous ; antenna, eyes, lateral and angular margins of the pronotum, three discal longitu- 
dinal fasciz to pronotum (of which the central one only reaches the anterior margin), a subquadrate spot at 
base of scutellum, a narrow submarginal fascia to corium extending to half its length, femora beneath 
(excluding apices), tibie, tarsi, three elongate spots on each side of prosternum, five streaks (four rounded 
and one transverse) on mesosternum, a rounded discal spot and a streak at angle of posterior margin of 
the metasternum, and the stigmata black. Corium with three oblique fuscous streaks; membrane 
bronzy ; connexivum alternately black and dull reddish. The first and second joints of the antenne are 
subequal in length, third shortest, fourth longest; the lateral margins of the pronotum are coarsely 
crenulate, the lateral angles strongly produced, with a slender apical black spine. 
Long. 28 millim., lat. pronot. angl. 13 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
One female specimen is all that we have received of this handsome and well-marked
