151. Corticaria Fagi, WoU. 



C. elongato-parallela angusta fiilvo-fen'uginea, capite prothoraceque profuude et subremote punctatis, 



hoc ad latera postice crenulato, fovea postmedia magnii profundi impresso, elytris striato- 



punctatis, antennis pedibusque vix pallidioribus.

Habitat Maderam borealem sylvaticam, ad Lombo dos Pecegueiros mense Julio a.d. 1850 copiosissime 

 lecta. 



C. narrower, more elongated and parallel than any of the foregoing species, very pubescent, pale fulvo- 

 ferruginous, and slightly shining. Head and prothorax beset with very large, deep, but some- 

 what remote punctures : the latter with the edges rounded and finely crenulated posteriorly ; the 

 postmedial fovea large and deep, but not quite so rounded as in the other species, — having a 

 tendency to be a little curved, or arcuated in front. Elytra regularly and distinctly striatc- 

 punctate. Antenna and legs concolorous with, or (especially the former) a little paler than, the 

 rest of the surface. 



The narrow and linear outline of the present Corticaria, in conjunction Avith its 

 pallid hue and its large hinder prothoracic fovea, will at once separate it from the 

 whole of the preceding species. It is apparently the Madeiran representative of 

 the C. elongata of Schuppcl, though clearly not identical with it, — since it is not 

 only somewhat darker, and less parallel and pubescent than that insect, but its 

 prothorax is less perceptibly crenulated posteriorly, and (together with the head) is 

 beset with extremely large, coarse and deep punctures ; whereas in the C. elongata 

 the punctures are so minute as to be scarcely perceptible. It is exceedingly local, 

 and would seem to be confined to the forest regions of intermediate and rather 

 lofty altitudes. The only district in which I have hitherto observed it is that of 

 the Lombo dos Peccgueu-os, where, during July 1850, I captured it in profusion, — 

 especially on the outer canvass of my tent towards the dusk of the evening and 

 after showers. The particular spot in which I was encamped (known as the Chilo 

 das Castanheiras) being thickly studded wdth enormous Spanish chestnuts, I am 

 inclined to suspect that it was from off that tree, rather than the native laurels, 

 that my specimens must have flowia.
