Similar to the genotype, but the frcntal keel is distinctly more 

 pronounced, though the frons is still highly polished, and the 

 legmina are much shorter and less convex.

Hab : Queensland, Bundaberg. 



Only a single female unfortunately. 



Haplodcll^ha.r gen. nov. 



Allied to Mvgaiiicliis \ characterized by the structure of the ver- 

 tex and by the radial vein not being forked. 



Head dorsally longer than wide, produced in front of the eyes, 

 apically rounded, the lateral and anterolateral keels being just 

 interior to the apparent margins ; within this is a keeled triangle, 

 the acute anterior angle touching the anterior margin of the 

 head ; there is also a median keel which forks a little anterior of 

 the middle, the short branches meeting the sides of the triangle 

 a little anterior of its middle. Frons nearly twice as long as 

 wide, lateral margins gentlv rounded ; there is a strong median 

 keel which meets the base without forking ; apical margin an- 

 gulate ; basally a little of the vertex is visible laterally. xA.nten- 

 nae short, subcylindric, not reaching apex of clypeus, second 

 segment about twice as long as the first. Genae triangular, the 

 apex blunt, that is to say, the median keels do not touch the 

 lateral keels of the frons apically. Clypeus tricarinate. Pro- 

 notum tricarinate, lateral keels fairly straight, diverging pos- 

 teriorly, usually not quite reaching the posterior margin. Scu- 

 tellum tricarinate. Dimorphic as regards the tegmina ; with the 

 brachial vein in the long-winged form, forking close to the sub- 

 apical line, the radial not forked ; there are 6 apical cells, the 

 first small .sometimes divided. Tibiae apically with 5 spines of 

 irregular size: spur of usual form, with 10 spines. First seg- 

 ment of hind tarsi longer than second and third together. 



There are two species, of which I have seen only females. H. 

 iuncicola is the genotype. The brachypterous forms may be se- 

 jmrated as follows : 



I Tergites vellowish. faintly marked with pale brown 



I iuncicola 



la Tergites brownish, marked with black and yellowish. 2 naias
