iiiticlulous, smooth or li no]}- punctate ; basal segment with discal 

 carintE not extending to apex ; tlie next two or three segments 

 laterally margined beyond their centre, with broad epipleuite ; 

 sixth ventral of J prominent, terebra usually concealed, hypo- 

 pygium retracted. Legs, and especially the femora, stout and not 

 elongate, with thoclaus stout; intermediate tibia* with calcaria 

 of very unequal length. Wings not broad, with the nervalus 

 nearly always oblique and postfurcal, rarely interstitial ; arcolet 

 wanting ; parallel nervure emitted from below centre of brachial 

 cell ; lower w ings with the nervellus oblique and distinctly 

 antefurcal.

Thomson says {loc. cit. p. 198) that this genus, which originally 

 included the whole tribe, as understood by Graveuhorst, is dis- 

 tinguished from Poh/diHus by its strongly unequal intermediate 

 calcaria, the pale markings on the head, the somewhat less 

 prominent face, less abruptly declivous occiput, and the less 

 constricted first abdominal segment ; I have, however, followed 

 Forster's clearer, though perhaps no more constant, definition by 

 placing herein those species with the basal metathoracic area 

 confluent with the areola, and reserving for Polyclistus those in 

 which these two area) are distinctly divided by a transverse 

 costa.
