Laius intermedius, n.sp. 



(J. Colour and clothing as in preceding except that the head 

 as blackish-green, the blotch on prothorax is smaller and rounded, 

 the median fascia and the apical triangle of elytra are larger. 



Head as in preceding, except that the fovea between eyes is 

 larger and shallower; basal joint of antennse as in preceding, 2nd 

 longer than wide, convex below, above with a groove commencing 

 at base continued almost to apex, then turned round and return- 

 ing almost to base, an obtuse tooth or projection at the inner 

 base, joined to 1st towards its outer edge. Frothorax and elytra 

 as in preceding, except that the subapical violet patch on the 

 •elytra is punctate only at its extreme edge and the sutural 

 'thickening is less pronounced. Length 4^, width 2 mm. 



5. As in preceding species. 



Flah. — Swan River, W.A. 



In living specimens the blue markings are very bright and 

 usually without a trace of violet tinge; the red is a bright scarlet. 

 T thought it possible that the extraordinary shapes of the 2nd 

 joint in the males of this genus were caused, or partially caused, 

 by shrinkage after death. I cannot, however, see the slightest 

 difference in living and dried specimens of the above species. 



Laius orcicornis, n.sp. 



^. Colour and clothing exactly as in preceding. 



Head finely punctate; a rather large round fovea between eyes; 

 ■clypeus feebly longitudinally impressed on each side. Basal joint 

 of antennpe slightly longer than 2nd, less swollen and curved than 

 in the two preceding species; 2nd joint barrel-shaped, a feeble 

 groove at the base on its upper surface, joined to lut in middle 

 of base. Prothorax less transverse than in nidicola. Elytral 

 puncturation as in nidicola but a little more irregular. Length 

 4i, width 2 mm. 



5. As in the two preceding species. 



Ilah. — Mount Barker, W.A. (Helms, Macsorley and Lea).
