Mr. R. E. Turner on Fossorial Hymenoptera. 129 



Genus ParacrABRO. 



The only representative of this genus is P. froggatti, Turn., 

 <a Victorian species. The genus is nearly allied to the wide- 

 rungino- genus Stigmus. 



Keg to the Species o/' Harpactopliilus. 



??• 



1. Prouotum with a distinct transverse dorsal 



surface, the angles sharply produced ; front 



yellow H. tricolor, Turn. 



Pronotum without a distinct dorsal surface ; 

 front black 2. 



2. The carina between the antennje produced 



at the apex in the form of a ploughshare, 

 overhangino; the base of the clypeus ; 

 recurrent nervure received distinctly be- 

 fore the first transverse cubital nervure . . //. arator, Turn. 

 The frontal carina low, not produced at the 

 apex ; recurrent nervure interstitial, or 

 very nearly so, with the first transverse 

 cubital nervure 3. 



3. Eyes separated from the posterior margin of 



the head by a space exceeding twice the 

 distance between the posterior ocelli .... 4. 

 Ej^es separated from the posterior margin 

 of the head by a distance scarcely ex- 

 ceeding the distance between the posterior 

 ocelli 5. 



4. Vertex rugose, mesonotum punctured ; wings 



hyaline, second cubital cell pointed on the 



radius H. kohlii, Turn. 



Vertex and mesonotum longitudinally 



striated ; wings fusco-hyaline, second 



cubital cell not pointed H. stdcatus, Turn. 



.5. Wings dark fusco-hyaline, second abscissa 



of the radius half as long as the first .... H. bicolor, Sm, 

 Wings hyaline, first abscissa of the radius 



about three times as long as the second . . H. steindachneri, Kohl. 



The genus Harpactophilus is confined to the Australian 

 and Austro-Malay region, all the known species being from 

 the Queensland coast, except H. Ucolor, the type of tlie 

 genus, which is from Mysol. i/. steindachneri seems to be 

 the Australian representative of bicolor, probably a geo- 

 graphical race. 



Key to the Australian Species o/Spilomena. 



1. Testaceous brown, the head black S. australis, Tuin. 



Black ; legs, antennpe, mandibles, and tegulse 

 testaceous brown 2.
