M. solidus, sp. nov. Latus ; convexus ; nitidus, sed indumento 

 opaco squainoso tectus ; piceo-niger, sed indumento ciner- 

 ascenti ; supra setis erectis castaneis vestitus, his hie et illic 

 condensatis (partim in tuberculis partim in superticie dorsali 

 positis) ; prothorace valde transverse, antice fortiter an- 

 gustato, supra in parte mediana antica sat fortiter compresso- 

 elevato, trans medium profunde sulcato, pone sulcum trans- 

 versim 4-fasciculato ; elytris striatis, interstitiis convexis, 

 passim fparte apicali sexta excepta) sat crebre tuberculatis 

 et fasciculatis ; sternis et coxis posticis grosse sat crebre sat 

 asqualiter punctulatis. Long., 2 1.; lat., 1-1- 1. 

 As I have only one specimen of this insect I have not sub- 

 jected it to the removal of the indumentum covering its upper 

 surface. It is, however, distinguishable from all the others be- 

 fore me by — in combination — its dark under surface, its elytra 

 having their whole surface except the extreme apex studded with 

 confused tubercles and fascicles of castaneous setae, and its sterna 

 and hind coxse extremely coarsely and somewhat evenly punct- 

 ulate. A small abrasion of the indumentum on the elytra reveals 

 the surface as crenulate-striate with strongly and roundly 

 elevated interstices. The fascicles and tubercles of the elytra 

 are so distributed that when the insect is looked at from behind 

 there seems to be a very deep wide furrow across the elytra 

 somewhat behind the middle. It is allied to M scoparius. Er., 

 and to the species sent to me by Mr. Lea as fascicular is ^ Macl., 

 but differs from both of them by, inter alia, the strise of the 

 •elytra being crenulate and their interstices strongly convex the 

 very coarse even puncturation of the sterna, &c.

 M. nigro-varius, sp. nov^ Ovalis; minus latus; sat convexus ; 

 subnitidus ; piceo-niger, sed squamis opacis cinereis dense 

 vestitus, antennis pedibusque plus minusve dilutioribus ; 

 supra setis erectis nigricantibus et nonnullis castaneis hie 

 disperse illic fasciculatim ornatus, nullo modo tuberculatus ; 

 prothorace valde transverso, antice fortiter angustato, supra 

 in parte mediana antica minus fortiter compresso-elevato, 

 trans medium late leviter sulcato crebre minus fortiter 

 punctulato haud fasciculato ; elytris sat fortiter punctulato-

 punctulatis suturam versus planis extrorsum gradatim magis

 Until the squamose indumentum has been removed the 

 sculpture of this species is scarcely discernible, although the
