A Tribe of flavidoLis or rulVsccnt species, usuall)' of soniewliat kirt^e 

 size. Thorax nitidulous and never strongly sculptured ; notauli distinct, 

 but rarely deeply impressed ; metathorax subdeclived throughout, and 

 not apically produced above hind coxae. Abdomen slender and not 

 deplanate; basal segment elongate and subparallel-sided, rarely subpetio- 

 late or subsessile, with the spiracles always before its centre and lateral 

 sulci of unique conformation (termed by some modern authors, glymmac) ; 

 terebra shortly exserted or subconcealed, J valvulae large and strongly 

 exserted. Tarsal claws strongly pectinate ; intermediate tibiae distinct- 

 ly bicalcarate. Wings very ample ; areolet in our indigenous species 

 never wanting, usually triangular, with the nervures subentire (the ex- 

 ternal often fenestrate below) and always coalescent above, emitting 

 the external abscissa of the radius in a strong curve, which basally 

 forms an acute angle with the internal abscissa of radius and is exactly 

 continuous \\ ith the inner nervure of areolet ; stigma never broad nor 

 triangular, often pale; nervellus intercepted above, very rarely at or below, 

 its centre. In all our genera, this group may be known by having the 

 external radius continuous at the base with the inner submarginal ner- 

 vure. 



With us it is a small group, comprising only a few common and ubiquit- 

 ous species, whose frequency renders a knowledge of their distinctions 

 more necessary than we have been inclined to hitherto consider it in this 

 country, when.' arc but three well-defined genera. In my attemjjted 

 "Revision" of the world's species, it was found necessary to allot them 

 only five genera (the inclusion of Wcshvoodia here was solely for the sake 

 of the remarks attached to it) and I considered Parahaliis distinct ; that 

 it is so is still open to doubt, and the slight divergence is insufficient to 

 warrant its retention in our fauna.
