360 INSECTA MADERENSIA. 



however a sylran. species, congi'egating between the loose bark of trees, moss, and 

 lichen, — from which it never wanders by day. Like most of its allies, it becomes 

 extremely active at night, as I have frequently experienced during my encamp- 

 ments in the wooded regions of lofty altitudes. I shall not indeed easily forget 

 the positive inconvenience which I suffered from it on the night of the 16th of 

 July 1850, wliilst encamped with the Rev. E,.. T. Lowe in the uplands of the 

 Fanal (more than 5000 feet above the sea), — when some unknoAATi cause l)rought 

 such a host of them, accompanied mth the A. nocticagans, into my tent that they 

 caused me no slight annoyance, by falling do^^^l from the canvass on to my Ijcd. 

 It would appear to be more especially aljimdant daring the summer months ; 

 nevertheless it occurs in the winter also, since I have taken it, hybernating, from 

 beneath moss on the trunks of the old vinhaticos at the edges of the mountain 

 plain of the Fateii-as, — which still remain to represent the ancient forest with 

 wMch that portion of the island must have been once densely clothed.

A. elongate-ovate, a little narrower in proportion tlian tbe last species, piceous, and densely variegated 

 witb a robust, decumbent, greenish, golden-green, and sometimes slightly coppery pubescence, — 

 reflecting more or less of a metallic splendour, though occasionally comparatively dull. Rostrum 

 slightly dilated at tbe apex ; almost unpunctured ; and with a narrow longitudinal channel, more 

 especially apparent between the eyes. Prothorax widest just behind the middle ; and obsoletely 

 punctured. Elytra rather finely punctate-striated; sparingly beset with elongated, suberect 

 additional hairs (rather more numerous and distinct posteriorly than in front) ; confusedly 

 variegated with more or less bright scales, or pubescence, the alternate interstices not being 

 much less regularly tessellated than those of the A. lamellipes. Antennm shorter than those of 

 that species, and rufo-ferruginous ; the second joint of their funiculus being just perceptibly 

 longer than the first, and their club elongate-oblong. Li'ys more or less brownish-testaceous, or 

 fusco-piceous : the tarsi paler, their terminal joint being rufo-testaeeous.
