312 INSECTA MADEREXSIA. 



distrnguislied by its broader and less fusiform outline, darker bue, more deeply 

 striated elytra, and by tbe very obsolete punctures of its prothorax. Tbe only 

 locality in which I have myself hitherto observed it is on the Dezerta Grande, 

 \\hcro, at the end of May 1850, I detected it in the utmost profusion in the rotten 

 stems of the Sllybum Marianum, Grtn. (the Carduus benedictits, or Holy Thistle, 

 of the ancients), throughout the entire length of the long valley which runs fi'om 

 the northern extremity towards the centre of the island. A single specimen how- 

 ever has been recently communicated to me by T. S. Leacock, Esq. of Funchal, 

 stated to have been taken in Madeira proper, though the circumstances of its 

 capture he was unaljle to recall. 



237. Cauloti-upis terebrans, Woll. (Tab. VI. fig. 8.) 

 C. subfusifomii-ovatus a?neus subnitidus, prothorace punctate, elytris nitidis striato-punctatis, an- 



tennis longiusculis pallido-ferrugiaeis, pedibus rufo-piceis. 

 Long. Corp. lin. 1^. 



Habitat ad latera necaon in cacuminibus montium Portus Sancti, mtra caules plautarum vcl in rupiuui 

 fissuris, rarissime : in summo ipso monte Pico de Faebo dicto (circa 16G0' s. m.) Aprili exeunte 

 A.D. 1818 duo specimina inveiii. 



C. .subfusiform-ovatc, being, proportionably, a little narrower and somewhat less expanded behind 

 than the last species, seneous, and shining. Prothorax much more deeply punctured tlian in 

 C.impius, the punctures being distinct and rather large; broadest behind the middle. Elytra 

 tolerably brilliant; rather deeply punctate-striated; and broadest about or a little behind the 

 middle. Antenrue longish, and pale ferruginous. Leffs rufo-piceous. 



Easily distingiiishaljle by its small bulk, comparatively brQliant and entirely 

 l)rassy surface, and by its deeply punctiu-ed prothorax. This last moreover is, 

 proportionably, somewhat more, and its elytra just perceptibly less, expanded 

 behind than is the case with the C. impius, giving it altogether a slightly more 

 fusiform appearance ; in addition to which it is not quite so deeply striated as that 

 insect. If the two examples which have come beneath my notice be tyi^ical as 

 regards size, the C. terebrans (even though somewhat larger than extreme speci- 

 mens of the impius and Chevrolatil) would seem to be the smallest CatttotrKpis, 

 on the average, of all the species here described. It is, apparently, excessively 

 local, being confined, so far as I have hitherto observed, to Porto Santo, — where, 

 during my ^dsit to that island with the Eev. W. J. Armitage in AprU and May 

 1818, I captm-ed a pair from out of the crevices of the rocks on the northern side 

 of the extreme simimit of the Pico de Facho (about IGGO feet above the sea) ; a 

 spot in which I first discovered the Taip/iiiis Loicei and IIiip)era liniato. Al- 

 though I searched diligently in the same place on two subsequent occasions, I 

 failed in detecting more ; and hence it may be presumed to be not only local, but 

 rare.
