Family ANTHOCORIDAE 
116. Piezostethus flaccidus n. sp. 
Near cursitans but larger and with the elytra almost entirely 
pale. Length 214 mm. 
Head black, polished. Antenne black, the apical two joints a 
little paler, third and fourth joints subequal, each shorter than the 
second. Rostrum attaining the intermediate coxze, testaceous. Pro- 
notum black, impunctate; anterior lobe polished, posterior trans- 
versely rastrate on the disk, the hind margin but feebly arcuated. 
Scutellum polished, impunctate. Elytra impunctate, entirely pol- 
ished, pale soiled testaceous, a little darkened on the clavus and 
cuneus; the tip of the clavus, hind margin of the cuneus and its 
exterior nervure embrowned; cuneus otherwise concolorous. Mem- 
brane clear hyaline, immaculate. Beneath deep black, mostly pol- 
ished, the female ovipositor only ferruginous. Osteolar canal long, 
distinct, broadly curved at apex and ending abruptly just before 
the anterior margin of the metapleura. Femora black, tibize and 
tarsi brownish-testaceous. 
One brachypterous example evidently belonging here has the 
female ovipositor black and the elytra testaceous, reaching on to 
the second segment of the tergum with the clavus and cuneus black.

tum rufous or rufo-piceous becoming black on the disk
