venter and antennae (the yellow-testaceons basal joint excepted), black. 

 Allied to B. dilatata, Am. & Serv., differs in Laving the pronotum a 

 little shorter, lateral part more dilated and rounded, antennsa more 

 slender and femora unarmed (SidZ). Long, 20; broad, 10 mill. 

 Reported from the Punjab. 



The following genera and species require further examination before 

 admitting them to the Asiatic list.

Tarsi 3-jointed : apical margin of corium more or less distinctly- 

 sinuate, very rarely rounded : membrane without basal areolas, transverse 

 basal vein emitting longitudinal veins : scutellum longer than bi-oad, part 

 placed far behind the frena : primary and subtended veins of wings ap- 

 proximate or contiguous, diverging towards the apes : hamus wanting. 



Genus PiEZOSTEENUM, Amyot & Serville.

 culss continuous, much elevated, higher in front than behind ; eyes rather 

 prominulous ; ocelli near the eyes : antennae 5-jointed, shortish, rounded, 

 first joint extending beyond the apex of the head, second longer than the 

 third ; rostrum extending beyond the first pair of coxse, first joint ex- 

 tending a little beyond the bucculae posteriorly : lateral margins of 

 pronotum very narrowly reflexed, basal part produced liindwarda and 

 covering base of scutellum which is triangular, longer than broad, acute 

 at apex ; frena extended beyond the middle of the scutellum : apical 

 margin of corium sinuate, exterior apical angle acute : membrane with 

 simple longitudinal veins, emitted from the transverse basal vein, proste- 

 thium simple : metastethium much elevated, posteriorly truncate, ante- 

 riorly produced, the produced part gradually compressly narrowed 

 forwards, extended to the first coxee, quiescent on the mesostethium : 

 apical angles of the abdominal segments prominulous in a tooth ; second

 touching the truncate posterior part of the metastethium : feet moderate 

 last pair distant ; femora unarmed ; tibise slightly furrowed above ; tarsi
