 Hab: Queensland, Moreton Bay. 

 Unknown to me. 



2. angustifrons, sp. nov. 



Disting-uished from L. aiisfraHcus by the elong^ate frons; (in 

 that species it is "almost as wide as long-.") Greyish testaceous, 

 vertex, lateral margins of frons (spotted with testaceous), mark- 

 ings on clypeus, etc.. middle part of pronotum and of scutellum. 

 extreme base of clavus, some o'bscure, small, markings on teg-

 side vellowis'h testaceous, frontal carinae pale ferruginous. Teg- 

 mhial veins more or less closelv speckled with sanguineous. 

 Wings pale smoky. Vertex a little longer than wide; lateral 

 margins of vertex and frons acutelv elevated vertically; on the 

 front within these are 3 carinae united basally acutangularly, 

 diverging a little posteriorly and roundlv uniting again. Frons 

 nearly twice as long as wide, wider posteriorly than anteriorly. 

 Rostrum reaching to posterior coxae, tapper apical angle of 

 tegmina about rig*ht angled. 



Length: 8 mill., hei'g'ht in profile about 4^ mill. 



H'ab: Queensland. Bundaberg (xi). arboreal. 



3. acitfipcniiis. sp. nov. 



Closely allied to L. aiigiisfifroiis. but smaller, and the upper 

 apical angle of tegmina distinctly acute and more prominent; 

 the anterior carina of vertex truncate, and more pronounced (it 

 is feeble and excavatelv angulate in L. angustifrons). The veins 

 are not, or very scarcelv, marked with sanguineous.
