452 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



snout than to the front of the prothorax. The eyes are very 

 similar to those of R. nasutus, — they are almost contiguous in the 

 male on the upper surface (more nearly than on the underside) 

 while in the female they are almost equally approximate both 

 above and below. In the male the fifth ventral segment is 

 densely clothed with long pilosity at and about the apex, while the 

 apical segment in the female is evenly pubescent and simply fringed 

 behind with longer hairs.

Angustissimus , ferruginous, elytris plus minus pallidioribus, 

 abdomine plus minus infuscato, tarsis posticis baud pallidioribus ; 

 prothorace brevi, lateribus rotundatim nee f oi'titer gibbosis ; elytris 

 costatis. [Long. 6, lat. 5 line. 



In some specimens the head, prothorax, legs, and even antennae 

 from certain points of view appear purplish-red, — especially the 

 dilated part of the femora and of the basal joint of the antennae. 

 Of previously described species this seems to be nearest to 

 M. acicularis, Pasc, from which it diff"ers by its unicolorous red 

 head, the absence of whitish-yellow colouring from its antennae 

 and hind tarsi, and the comparatively greater width and less 

 length of its prothorax. 3f. capita and exilis, inter cdia, are much 

 larger and ha\e the prothorax much more strongly bulging out on 

 either side in front of the posterior constriction. M. ru/us (which 

 I have not seen) is described as being more than twice as large 

 with the thorax spined on either side. M. subclavatus, inter alia, 

 has blue-black elytra. In the present species the disc of each 

 elytron bears two longitudinal costse between the costate suture 

 and margin.
