A smooth species with legs mainly red and mesonotum bilineated with 

 flavous. Head short, transverse and narrowed behind the large and 

 internally deeply emarginate eyes ; face subquadrate, sparsely punctate, 

 and centrally subelevated longitudinally ; cheeks short ; frons unequally 

 impressed and somewhat smooth ; clypeus depressed ; $ with mouth, 

 clvpeus, face and the frontal orbits flavous ; 9 with palpi and generally 

 the internal and external orbits narrowly flavous. Antennae filiform, 

 somewhat stout and not apically attenuate, infuscate and more or less 

 broadly testaceous beneath, with the joints apically darker ; scape of J 

 flavous, of 9 generally testaceous, beneath. Thorax stout and gibbulous 

 with an elongate line before and another beneath the radix, and two 

 discal vittae, flavous ; J often with two pectoral marks testaceous ; 

 pleurae smooth and sparsely punctate ; metathorax somewhat strongly 

 punctate with the supracoxal and petiolar areae smoother and more 

 sparselv punctate ; spiracles oval. Scutellum apically and the postscutel- 

 lum flavous. Abdomen double length of head and thorax and as broad as 

 the latter, cylindrical with the three or four basal segments strongly punc- 

 tate ; basal segment obsoletely bicarinate with the intervening space not 

 deeply canaliculate, basally excavate and a little elevated from centre to 

 apex ; second foveate on either side ; apical margins of segments 

 slightly elevated, more nitidulous and rarely badious, with obsolete lateral 

 impressions ; seventh of J longer than broad, apically constricted and 

 the hypopygium somewhat strongly acuminate ; terebra a quarter the 

 length of the abdomen, compressed and pilose with the spicula badious. 

 Legs normal, red or fulvous with the anterior mainly flavidous ; posterior 

 tibiae broadly white-banded before their infuscate base, tarsi infuscate 

 with the basal joint paler, or in ^ all the joints basally whitish ; tarsal 

 claws stout and in 9 distinctly explanate-dentate basally. Wings 

 flavescent or hyaline ; stigma and radius piceous, radix and tegulae 

 flavous or in 9 ferrugineous ; areolet subregular, subsessile ; nervellus 

 intercepting above centre. Length, 7 — 14 mm. 



This species is very variable in size and closely resembles P. brasskariae, 

 but the basal segment is centrally much less elevated, its carinae obsolete 

 with the intervening space not apically excavate, and the hind tibiae are 

 always white at their basal third (Holmgren). Both sexes dift'er from 

 P. brassicariae, in the dcterminatelv white hind tibial band and not cen- 

 trally elevated carinae of the basal segment ; the 9 i'^ having the orbits 

 and vertical dots flavous, the humeral and discal mesonotal lines, a 

 quadrate apical .scutellar and transverse postscutellar marks and their 

 lateral carinae pale, the basal metanotal area parallel-sided, anterior legs 

 not basally black and the tegulae with callosities before and below them 

 generally pale ; the J in the entirely pale face and broad frontal and 

 vertical marks, confluent pale discal and humeral mesonotal lines, and 

 the seventh segment discal ly deeply punctate and laterally sinuate. 



I do not myself believe that this species and the last are distinct since 

 the basal segment, though often more deeply canaliculate, varies as much
