 subrotundatis ct postice subito decm'\'is), sutura interstitiisque ob-

 Habitat ins. Hierro, in clivis inter mare et oppidum Valverde, mense 

 Februario a.d. 1858, sub lapidibus parce repertus. 



Of tbe present Lichenophagus I have seen hitherto but five ex- 

 amples, all of which were taken by myself in the island of Hierro, 

 about midway up the ascent from Port Hierro to Valverde, during 

 February 1858 ; and it is a curious fact that they are totally distinct 

 specifically from others (the L. suhnodosus, described below) which I 

 captured at a slightly higher elevation, near to Valverde itself. Apart 

 from minor features, the L. audus is remarkable for its comparatively 

 swollen second funiculus-joint — which, if anything, is altogetlier a 

 trifle larger than the first (not merely in length, but even in breadth), 

 whilst the remaining articulations are exceedingly short, subequal, 

 and monUiform. In less important particulars, it may be known by 

 its (rather abbreviated) pi'othorax being a good deal rounded at the 

 sides, with the punctures well defined but not very large, and with 

 the rudiments of a glabrous central keel at the extreme base ; by its 

 elytra (which are not very coarsely punctate-striated) being subovate 

 in outline (that is, a little narrowed anteriorly, with the shoulders a 

 good deal falling away, ratlier suddenly decurvcd at the apex, and 

 separately rounded along their base) ; by the seta) of its entire sur- 

 face being so minute as to be traceable only under a high magnifying 

 power ; and by its antennse being altogether shortish, and Avith their 

 scape not very much cm-ved. 



562. Lichenophagus tesserula, n. sp. 



L. prsecedenti similis sed plerumque lajtius tesseUatus et setulis sen- 

 sim longioribus (sed brevibus) obsitus ; rostro obscure (nee solum 

 antice) pallidiore ; prothorace paulo longiore, ad latera minus ro- 

 tundalo, profundius punctate (punctis magnis), simplici (postice in 

 medio baud carinato) ; elytiis paulo magis oblongis (ad latera sen- 

 sim rectioribus, per basin conjunctim suborn a rginatis, ad humeros 

 oblique truncates vix magis porrectis, et postice minus subito de- 

 curvis) ; antennis vix longioribus, scapo sensim magis curvato et ad 

 basin etiam robustiore, funiculi gracilioris art" 2''" prin!o angustiore, 

 reliquis brevibus (sed vix brevissimis). — Long. corp. lin. 2\-2^. 

 Habitat in inferioribus intermediis(|ue Tenerift'a;, hinc inde vulgaris. 

 This species appears to be widely spread, at low and intermediate 



elevations, in the north of Tcneriff"e — where it occurs, during the
