76 REVISION OF THE SUBFAMILY TENEBRIONl N.f!, 



striate-punctate, intervals sharply ridged, seriate punctures larger 

 than in 31. tibialis, more closely placed than in M. laticollis Pasc, 

 intervals apparently quite impunctate; underside very finely 

 striolate, prosternum finely transversely rugose, femora smooth, 

 tibiae coarsely punctate on under surface, (on upper surface at 

 apex only). Front tibije moderately curved and enlai ged at apex, 

 external carina triangularly enlarged at apex, middle and hind 

 tibiie less curved and enlarged, apical spurs long. Dimensions 

 of type (^, 21 X 8'5mm.; other specimens from 17 x 6*2 mm. 



Hab. -Dorrigo, N.S.W.(Il. J. Tillyard). 



Five specimens examined, all males. I can find no females to 

 match them. The species is separated from its allies by the great 

 width of the prothorax, very little less than that of elytra at 

 base, also the great width of elytra compared with length. Thus 

 in M. laticollis Pasc, the elytra are nearly exactly twice as long 

 as w^de. In M. la/ior, the length is only once and two-thirds 

 the width. I ype in author's Coll. 



TOXICUM INSIGNE, n.Sp. 



Elongate, parallel, dull brownish-black above, without the usual 

 indumentum; oral organs, antennae, legs, and underside piceous. 



(J. Head concave, punctate, the clypeal horns degraded into 

 conical tubercles situated at the corners of the clypeus, frontal 

 horns strongly incurved at base and apex, the apices slightly 

 widened and deflexed, nearly meeting, with a fringe of golden hair 

 on the outside only, extending but narrowing almost to the extreme 

 base; antennae with a distinct 4-jointed club, the 8th joint clearly 

 differentiated in size and shape from the 7th. Prothorax bisinuate 

 at base and apex, widest in front, about as wide as long (4 mm.), 

 anterior angles rather squarely rounded, sides nearly straight and 

 gently converging to base, posterior angles obtuse, not produced ; 

 disc densely and uniformly punctate, sometimes with a faint de- 

 pression to denote a medial line. Scutellum curvilinearly triangu- 

 lar. Elytra wider than prothorax at base, and twice and one-half 

 as long, shoulders rather square, sides nearly parallel till near 

 apex; striate-punctate, the intervals convex, the punctures smaller 

 and closer than in T. punctipenne Pasc, the basal part of elytra
