The black elytral spot commences on the suture slightly in front 

 of the middle and reaches back nearly to the apex; it is of oblong- 

 oval shape and at its widest touches the 2nd elytral costa on 

 either side. The rostrum equals in length about three-quarters 

 the length of the prothorax. The antenna? are like those figured 

 (Trans. Ent. Soc, 1887, PL I., fig. 2) by Mr. Waterhouse as per- 

 taining to M. mjipennis, Fab., their branches being very evidently 

 longer than in M. erythropterus, Er. The punctures in the inter- 

 costal series on the elytra are about as strong as in M. erythropterus, 

 but are less transverse, and the two rows of each pair are separated 

 from each other much as in that species. Probably this insect 

 resembles M. rujipennis, Fab., but differs from it at any rate in 

 its elytra being bi-colorous ; also (if Dr. Erichson identified M. 

 rujipennis correctly) in its prothorax being much less elongate.

Ater, prothoracis lateribus et elytrorum singulorum marginibus 

 omnibus (basali prope scutellum excepto) aurantiacis, horum 

 costis hie illic aurantiaco-tinctis ; prothorace vix transverso, 

 7-areolato ; elytrorum sutura margine laterali lineisque 4 

 discoidalibus costatis, intervallis antice obscure biseriatim 

 postice confuse cancellato-punctulatis. 

 Maris (exempli typici) rostro brevi, antennis sa't fortiter (fere 



ut M. erythropteri maris, Er.) pectinatis. 

 Feminse (exempli typici) rostro multo minus brevi, antennis 



fere ut M. erythropteri feniinse. 

 The orange border of the elytra is at its widest at the apex 

 (where it is wirier in the female example before me than in the 

 male) and is markedly wider at the lateral margins than at the 

 suture ; in the male before me the elytral costa? are scarcely 

 splashed with orange colour, in the female very distinctly ; 

 probably these colour characters are variable. The rostrum in the 

 male is scarcely longer than the 3rd joint of the antenna?, in the 

 female it is nearly as long as the 3rd and 4th joints together.
