In the above C|Uoted paper I have made some remarks ou tli« 

 characters and systematic position of this insect. It has a super- 

 ficial resemblance to a miniature Atelocera (near which Distant 

 placed it), but there is no real relationship between these two genera. 



The monotypic genera Luhe/ifitis, Hyjyolcus, and Turrulndana 

 form a well defined little group not represented outside the Aus- 

 tralian continent. They may be distinguished as indicated below. 



1 (4) Head about as long as broad, not longer tban 



pronotum in the middle, anteocular part 

 moderately narrowing from base to apex, 

 laterally more or less distinctly imisinuate. 

 Apical margin of pronotum neither levigate 

 nor elevated 



2 (3) Head rounded at apex owing to juga and cly- 



peiis being equal in length ; bucculae rather 

 high. Lateral margins of pronotum narrowly 

 depressed throughout, at apex with a short 

 blunt tooth directed outwards - - Lulentiui, Stal. 



3 (2) Head shortly bicuspidate at apex owing to juga 



being longer than clypeus ; bucculae low. 

 Lateral margins of pronotum rather broadly 

 laminately depressed, gradually more broadly 

 so toward the apex, which is sulitriangularly 

 lobately produced forwards to about the level 

 of anterior margin of eyes - - - Hypolcus, Bergr. 



4(1) Head one-half longer than broad and longer 

 than pronotum in the middle, anteocular part 

 strongly narrowing from base to apex, later- 

 ally bisinuate. Apical margin of pronotum 

 levigate and subelevated behind interocellar 

 space of head. Lateral margins of pronotum 

 as in Luhe7itius .... Turrubulana, Dist.
