Mr. T. V. Wollaston on Additions to Madeiran Coleoptera. 291 



illo in fronte obsolete binodoso necnon utrinque costato ; elytris 

 paulo obscurioribus, valde profunde seriatim punctatis, punctis 

 maximis, interstitiis alternis paulo elevatis, irregulariter subundu- 

 latis ; antennis brevibus pedibusque paulo clarioribus.

Habitat in montibus Maderee ; sub cortice Platani laxo supra urbem 

 Funchalensem Dom. Bewicke sat copiose reperit. 



M. oval, rufo-ferruginous, with the elytra a shade darker. 

 Head with two very obscure elongate nodules in the centre of 

 its forehead, and with two raised costse (as in the M. asperatus) 

 on either side, arising from the inner and outer margins of the 

 eye (which they consequently enclose) and continued forwards, 

 gradually approximating until they reach the insertion of the 

 antennae, where they join. Prothorax very uneven, as in the 

 M. asperatus, but a little less developed than is the case in that 

 insect. Elytra very deeply seriate-punctate, the punctures, 

 especially those towards the suture, being enormous, and so 

 closely packed together that the interstices (the alternate ones 

 of which are slightly raised) appear irregular or minutely undu- 

 lated. Antenna and le^s, the former of which are short, rufo- 

 testaceous. 



In its 10-articulated antennae this little Metophthalmus agrees 

 almost exactly with the M. asperatus, except that they are alto- 

 gether rather shorter — caused by the joints betwefin the minute 

 conical third one and the club being (as in the M, exiguus) more 

 abbreviated or moniliform, and the first joint of the clava itself 

 being rather less developed. In the construction of its eyes and 

 iee{, and in the singular position of the former, no less than in 

 the serrated margins of its head, prothorax, and elytra, it is 

 identical with that insect. Its main differences lie in its smaller 

 size and more elliptic outline, in its more ferruginous hue, in its 

 less apparent inner frontal costse (or elongated nodules), and in 

 its very much larger elytral punctures, which are so enormous 

 and closely packed together as to cause the slightly raised alter- 

 nate interstices to appear less straightened and costate, or more 

 undulated and irregular. From the M. exiguus it may imme- 

 diately be known by {inter alia) its larger size and relatively 

 broader outline, and by the darker colour and immensely larger 

 punctures of its elytra. 



It is to Mr. Bewicke that we are indebted for this interesting 

 addition to the fauna, several specimens of it having been cap- 

 tured by him from beneath the dead bark of Plane-trees in the 

 grounds of the Palheiro, on the mountains to the eastward of 

 Funchal. Mr. Bewicke has presented me with types ; and he 

 has also placed others in the British Museum, as well as in the 

 collection at Oxford.
