are as described by Erichson except that the hind tibise are more 

 strongly sinuate on their inner outline than I should understand 

 by the term " suhrectce " and it should be added that the hind 

 tibiae are decidedly incrassate, — no doubt a sexual character, also 

 that the suture between the first and second ventral segments is 

 extremely fine and the sej^ments themselves on the same plane. 



M. vetulus, Er. I feel no doubt of this being the female of 

 31. sterilis. It difiers from it (as rigidus does from crudus) in 

 being of somewhat wider and stouter build with the tibise con- 

 siderably more slender and evidently less sinuate on their inner 

 outline. The elytra have their alternate interstices distinctly 

 elevated. The elytral markings mentioned by Erichson as present 

 in vetulus are very feebly defined and to my thinking merely 

 indicative of freshness of condition in the specimen ; I attach no 

 specific importance to them. 



PERPERUS. 



P. {Nothrodes) languidus, Er. Erichson's generic name is 

 (as noted by Lacordaire) a synonym of Perperus. The species is 

 very well described by its author. I cannot separate it from 

 a species of which I have examples from N.S. Wales and Gipps- 

 land, which Mr. Lea has sent to me as insularis, Schouh., but 

 which T believe to be innocuas, Schonh. Unfortunately most of 

 the pubescence is gone from the type specimen of languidus (e.g. 

 the four vittse described as marking the pronotum), so that it is 

 perhaps not justifiable to say positively that it is identical with 

 innocuus, but I can find no structural character on which to 

 separate it. The species that I take to be iimdaris, Schonh, has 

 a broad white lateral elytral vitta, the humeral angles of the 

 elytra much better defined and the elytral interstices less fiat, — 

 all of them characters referred to by Schonherr in his description. 



P. convexipermis, sp. nov. Piceus, squamis cinereis et fuscis 

 intermixtis vestitus ; rostro quam prothorax parum breviori, 

 supra vix manifesto carinato, ad apicem modice dilatato ; 

 an tennis piceo-ferrugineis, funiculi articulo 2° maris basali

 rotundato, supra sat crasse (nee profunde nee confertim) 

 punctulato, fusco-trivittato ; elytris fortiter convexis, sat

Notable for its extremely convex elytra. Looked at from the 

 side the prothorax appears only half as high as the elytra
