side. Thé elytra are much more narrow at the base than 

 on the top, very convex, entirelj^ metallic blue, except tbe 

 very extreme apical margin, which is yellow; firmly grown 

 together, on the basal half strongly and thickly punctured, 

 the punctures becoming more and more obsolete towards 

 apex, one row of larger punctures distinctly visible, the tips 

 softly rounded; wings rudimentary, reduced to small triangulär 

 appendices. Legs very long, påle yellowish, the knees slightly 

 infuscate, the coxse fuscous, on the ventral side the head, the 

 prothorax, the sternum, and the two first abdominal seg- 

 ments (J^ and $) metallic blue or green, the other segments 

 dark with posterior margin narrowly påle, the last segment 

 with a broader yellow margin. 



Lengtli of body 16 mm. 



Of this beautiful species I have taken five specimens, 

 3 (^c? ^^^ 2 $5» under stones, where it burrows holes in the 

 damp sand on the banks of the Fitzroy River in the vicinity 

 of Noonkanbah in the Kimberley-District. 



The species is apparently allied to M. castelnaui Sloane, 

 but differs by the lateral carina on prothorax, extending 

 further backwards, the fuscous part of prothorax between 

 the anterior margin, and the anterior träns versal impression, 

 the deep blue elytra, the rudimentary wings etc. It also 

 shows affinity to M. marginicollis Sloane, but differs by the 

 incomplete lateral börder of the prothorax, the påle, testaceous 

 femora, the elytra being widest behind middle, and of a 

 uniform deep blue colour, except the extreme apical margin, 

 with the punctures distinctly extending behind the middle etc.

8. Distipsidera parva Macl. (Fig. 2). 

 — It is only with some hesitation that 

 I refer two female specimens from Ather- 

 ton, North Queensland (January 1913) 

 to this species. They are of the same size 

 and elytra with the same markings (see 

 Fig. 2), but labrum has a broad piceous 

 margin instead of a narrow one.
