486 INSECTA MADEREXSIA. 



acutiusculo. Palpi maxillares elongati clavati, articulo primo vix parvo flexuoso, secundo multo 

 longiore subclavato, tertio breviore primi longitiulinc, ultimo magno securiformi : labiales (XI. 2/) 

 subclavati, e scapis ligulse connatis surgentes, articulis primo et secundo subajqualibus, ultimo 

 majore elongate subfusiformi apice lenter truncate. Mentum subquadratum basi angustatum, 

 apice integrum. Ligula robusta subcoriacea lata, antice rotundata ciliata. Pedes (XI. 2^) sub- 

 graciles : tibiis parce ct minute setosis : tarsis (XI. 2g, 2h, 2 i) heteromeris, articulis simplicibus 

 usque ad penultimum longitudine decrescentibus, primo (prsescrtim in posticis) longiusculo, 

 ultimo subclavato unguiculis in medio obscure denticulatis munito. 



One of the most indigenous genera of our present fauna ; and approaching 

 nearer, I think, in habits and aflBjiity, to Scaphklema of Eedtcnhacher than to 

 an^-thing else \\\i\\ which I am acqu^ainted. It is however abundantly distinct 

 from that group, — receding from it not only in its convexer and apterous body, 

 more ample and posteriorly broader prothorax {that of Scapliklema being narrower 

 at the base than the coleoptera, and moreover very deeply excavated in front, and 

 ■with its sides strongly margined), and in its imstriated, subconnate elytra ; but 

 likewise in points even more purely structiu'al, since its mandibles are robustcr 

 than is there the case, neither are they so compressed, nor bifid (although biden- 

 tate) at their tips, the terminal joint of its maxillary palpi is much larger and 

 more securiform, its ligula is thicker and anteriorly rounder, its metasternum is 

 bipartite behind (instead of truncated and simple), its tibiae are powerfully spinu- 

 lose (especially at the extreme apex, — where also the two internal spines are much 

 longer than those of that genus), and its claws will be perceived under the 

 microscope to be minutely denticulated about the middle of their inner edge, a 

 circumstance of very rare occui'rence in the Diaperidce. In its elliptical outline 

 indeed and punctulated surface, as well as in its obsolete ^^iugs, cloven meta- 

 sternum, and spinulose tibia?, it even approximates Zophosis (in which however the 

 elytra, instead of being s?;6connate, are completely soldered together) ; nevertheless 

 it not only wants the produced hinder prothoracic angles, and the peculiarly 

 shaped eyes, which are there so conspicuous, but the modifications of its oral 

 organs (particularly of the mentum, which is comparatively small, and narrowed 

 at the base, as in the tj^pical Dkqieridcc, and does not conceal the lower parts of 

 the mouth) will altogether remove it from the whole family of the Fimeliadce.
