202 • MEMOIRS OF THE QUEENSLAND MUSEUM. 



minutely rugo so punctate, gibbous in front ; scutellum a little more shining, with a 

 median depression ; area of metathorax with rather weak plicse, failing distally ; 

 tegulse brown Avith pallid margins ; wings hyaline, slightly dusky, the apex darker ; 

 stigma and nervures dusky reddish brown ; second submarginal cell rather small, 

 third very large ; first recurrent nervure meeting second transversocubital ; outer 

 recurrent and transversocubital weakened ; hair of legs fuscous on outer side, pale on 

 inner, the middle tibiae with a stiff pale orange brush near apex ; abdomen with the 

 first segment and basal half of second very distinctly though very minutely punctured, 

 the parts beyond with only scattered piHferous punctures ; no hair-bands or patches ; 

 apex with fuscous hair ; venter with shining white hair. 



Hab. : Oxley, Brisbane, at Leptospermum, Sept. 8, 1914 {Hacker 148). 

 P. speculiferus was described in 1912 from Victoria ; I give a new description 

 from the Brisbane specimen. The species is somewhat variable. 



Parasphecodes leptospermi n.sp. 



9- Length about 9-5 mm., expanse fully 17 ; robust ; head, thorax, and legs 

 black ; abdomen with the first two segments bright chestnut-red, the third more 

 dusky, but still red, the others black ; head broad ; mandibles black ; chqieus bril- 

 hantly shining, with scattered punctures ; front rough but ghstening ; antennse dark, 

 the flagellum reddened at tip ; hair of head and thorax dull white, much blackened 

 dorsally ; mesothorax finely and extremely densely punctured ; scutellum bigibbous, 

 the elevations shining though punctured ; area of metathorax with weak irregular 

 rugae ; tegulse rufopiceous, with the anterior margin pallid ; wings dusky hyaline, 

 darker apically ; first recurrent nervure joining apical comer of the large second 

 submarginal cell ; middle femora with a brush of red hair beneath at base ; abdomen 

 with first segment, and second except apical depression, fineh^ and distinctly 

 punctured. 



Hab. : Oxley, Brisbane, at Leptospermum, Sept. 8, 1914 {Hacker 149). Allied 

 to P. speculiferus, but easily knowTi by its large size and black apical segments of 

 abdomen. It appears to be closest to P. hybodinus Ckll., described from a male 

 collected in Victoria, but on comparing specimens I do not think they are the sexes 

 of the sajne species. There is also some resemblance to P. tilachus Smith.
