INSECTA MADERENSIA. 389 



but likewise iu its comparatively large and triangular scutellum, in its shining, 

 brassy surface (on which there are distinct indications of suberect additional pile), 

 in its deeply punctm-ed prothorax, and in its elytra being scarcely perceptibly 

 striated. In the structure of its antennae and legs, moreover, it differs slightly 

 from the two preceding species, — since the former have their scape more curved, 

 whilst the latter are but slightly expanded at their extremity, and have the outer 

 apical angle of the front pair regularly rounded off. With such characters as 

 these, it is possible that it may not be correctly associated with the AnemopMli, 

 as described above ; and hence I have removed it into a separate section, in case 

 that future investigations should render it desirable to detach it from the group. 

 It does not appear to have any tendency to assume the lichen-infesting habits of 

 its allies, the few specimens which I have liitherto taken having been from 

 beneath stones in the open country, and at low elevations. The Campo de Baxo 

 of Porto Santo is the only district in which I have observed it, where I captured 

 several examples, principally towards the eastern base of the Pico d' Anna Perreira, 

 during April of 1849. 



Genus 126. LICHENOPHAGUS, WoU. (Tab. VIII. fig. l et 3.) 



Corpus sat parvum, elongato-ovatum, vix convexum, densissime squamoso-variegatum : rostro ut in 

 Anemopliilo, sed paulo longiore et subparallelo (apicera versus vix acuminato) ; scrobe magna 

 lata, infra ocidos profunda et ibidem curvata ; oculis parvis subrotundatis : prothorace ad latera 

 rotundato : scutello minuto subtriangulari : elytris subeonnatis : alts obsoletis. Antenna (VIII. I a) 

 ut in genera praecedenti, sed paulo longiores, scape valde curvato atque ad apieem multo magis 

 incrassato. Pedes (VIII. 1 b) valde robusti, in utroque sexu simplices, tibiis anticis ad apieem 

 ipsum solum incm-vis.

It is not without some hesitation that I propose another genus amongst these 

 obscm-e Cyclomides ; and I would merely therefore wish to regard the present one 

 as provisional, since it is not improbable that intermediate species may occur to 

 connect it Avith the last, to which in many respects it is clearly allied. Still, in 

 the absence of those links, which we cannot assume to exist, it is not possible 

 to admit the two insects which represent Lichenopliagus into that division, their 

 simple tibiae, ia conjunction with theu" immensely thickened and greatly curved 

 scape, and theu- large and deep antennal groove (which scarcely ascends so high as 

 that which obtains in AuemopMlKs, or at any rate is more apparent and arcuated 

 beneath the eyes), at once preventing such an amalgamation : whilst, in addition 

 to these primary distinctive characters, their superior bulk and densely scaly 

 (instead of pubescent) sm-faces, combined with their apically broader and almost 

 parallel rostrum, then' less duninutive eyes, and theu- longer and even robuster 

 limbs, would seem stiU further to render their isolation necessary. They appear 

 to be of entirely lichen-infesting habits, in which respect they agree with the
