74 REVISION OF THE SUBFAMILY TENEBBIONIN^, 



Elytra wider than prothorax at base, and twice and one-third as 

 long, shoulders rather squarely rounded, sides narrowly margined, 

 striate-punctate, with nine rows, besides a short scutellary row of 

 rather small punctures, closely placed in deep striae, intervals 

 strongly convex and distinctly punctate (more evidently so than 

 in M. laticollis Pasc), gula densely and coarsely punctate, pro- 

 sternum finely rugose-punctate, metasternum, abdomen, middle and 

 hind femora very finely rugose and minutely punctate; front 

 femora more densely and coarsely punctate, front tibiae swollen in 

 middle, strongly widened and curved near apex only, this wide 

 curved lobe coarsely punctate ; earinate on outside edge, this carina 

 widened into a rounded tooth or emargination at apex, with two 

 short blunt spurs; middle tibiae strongly curved and similarly but 

 less widened at apex, hind tibiae slightly curved with an angulate 

 emargination or triangular tooth on inside edge below the middle, 

 apex less enlarged than in the other tibiae, the four hind tibiae with 

 long apical spurs. 



C^. With all tibiae straight, much less enlarged at apex, hind 

 tibiae without the emargination. 



Dimensions of type (J, 20 x 8 mm,, other specimens from 

 18 X 7 mm.; of 9, 19-23 x 7-9 mm. 



Hah. — Victorian Alps (The Author), Queensland C^), and New 

 South Wales. 



Three male specimens examined, two from the Victorian Alps 

 taken by myself, with four corresponding females; the third male, 

 with a female, is labelled N. Queensland, but I have no record of 

 their capture; a very large female was taken by my son, at 

 Gynken, Blue Mountains. 



The species is easily separated from its allies, in male specimens 

 by the single tooth on the hind tibiae. It has the polished surface 

 of M. dentipes, with much more anteriorly narrowed prothorax 

 and sharper angles. Even female specimens may be distinguished 

 from M. laticollis by the more polished black colour, the more pro- 

 duced and sharper angles, and widened margins near the front 

 angles of prothorax. Types in the Author's Coll.
