72 INSECTA MADERENSIA. 



reflexis, elytris diluto-testaceis striatis, striis ad latera evanescentibus, fascia subapicali obsciira 

 nigrescenti ornatis et singulo punctis duobus distinctis impresso, pedibus testaceis. 

 Long. Corp. lin. 12. 



Habitat insulas Maderenses, in subsalinis ad ostia rivuloram, vel per litora maris, inter lapillos 

 fodiens ; rarissimus : duo specimina tantum vidi, unum so. in ins. Portus Sancti Decembri 

 mense a.d. 1848 a meipso inventum, et alteram a Dom. Rousset ab ora Funchalensi maritima 

 nuperrime communicatum. 

 Aniico cl. A. White, Arm., Musei Britannici comiti, hoc insectum valde indigenum et certe no\um 

 tribiii. 



T. elongate, parallel, depressed, shining, and rufo-ferruginous. Head large, more or less riifo-piceous, 

 with two very deep longitudinal furrows down the forehead; eyes jn'ominent. Prothorax cordate, 

 margined, especially towards the base, where it is a little retiexed; the extreme posterior angles 

 rather prominent and acute ; with a distinct dorsal channel ; but with no appearance of fovese 

 behind. Elytra testaceous, striated, the striae not being perceptibly punctate and vanishing 

 towards the margins ; with two deep impressions on the disk of each ; and with an obscure, 

 cloudy, ill-defined patch, common to both and forming an almost obsolete subapical fascia, 

 slightly infuscate. Antenna infiiscate towards their apex. Legs testaceous. 



Apparently one of the rarest of the Macleiran Coleoptera, residing, like the 

 European Blenuis areolatus and its allies, beneath shingle in brackish spots, into 

 which it burrows with great dexterity. In spite of my constant researches in 

 these islands I have hitherto captured but a single specimen, — detected, during 

 December 1848, at the edges of a small stream in the island of Porto Santo, knoA^-n 

 as the E-ibeiro de Serra de Fora, at a short distance l)efore it empties itself into 

 the sea. A second example however has been recently communicated to me by 

 M. Rousset, — discovered, I believe, on the beach near Funchal. The Madeii-an 

 representative is somewhat more highly coloured than the Porto Santan one, its 

 suliapical fascia being more distinctly developed; but whether this is merely 

 accidental, or would hold good on a larger scale, I am unable, in the absence of 

 further evidence, to decide.
