new Species of Diploptera. 45 



deeply emarginate at the apex, median segment truncate, 

 divided longitudinally by a narrow furrow ; scutellum flat. 

 Petiole of abdomen as long as thorax, very slender at base, 

 gradually widening towards the apex ; second abdominal seg- 

 ment about twice as broad as petiole at apex. Punctured 

 slightly on vertex of head ; the whole insect shining, sparsely 

 covered with testaceous pubescence. 



Length 10 mm. 



Hub. Cairns, N. Queensland, April 1902 (R. E. Turner) ;

All the specimens were captured on one flowering bush at 

 Kuranda, about 14 miles from Cairns, at an elevation of 

 1100 feet. 



Intermediate between Eumenes and Pareumenes as defined 

 by Saussure, Et. fam. Vesp. Suppl. p. 133. It resembles 

 Pareumenes in the form of the petiole, but the tubercles 

 are only indicated by minute swellings on each side. This 

 is the first described Australian species with any tendency 

 towards Pareumenes.

Four narrow longitudinal lines on petiole, two on the

Wings hyaline, tinged with fuscous on the fore wing

Head, thorax, abdomen, and legs covered with short dense

Clypeus rather longer than broad, narrowly produced 

 towards apex, terminated in two small teeth, intervening area 

 transverse. Mandibles deeply toothed. Thorax robust ;
