INSECTA MADERENSIA. 521 



leviter subcrenato-sti-iatis, interstitiis minute punctulatis apicem versus leviter seriatim tubercu- 

 latis, antennis pedibusque testaceis. 

 Long. Corp. lin. 3^-5. 



Habitat Maderam australem sub lapidibus, prsesertim per oram maritimam et in locis minus elevatis, 

 ab autumno usque ad ver novum vulgaris. 



H. elongate-ovate, ferruginous (either obscure or rufescent, occasionally of a somewhat reddish-cin- 

 namon hue), and slightly shining. Prothorax scarcely so wide or convex (in proportion) as that of 

 the last species, and not quite so densely punctulated ; subquadratc. Elytra lightly subcrenate- 

 striated (the strise being sometimes very faint) ; the interstices more finely punctulated than the 

 prothorax (though very much more coarsely than in the H. futilis), and with the hinder tubercles 

 tolerably distinct. Legs and antenna testaceous. 



The palest of the Madeiran nelopicl(V ; and an exceedingly distinct species, both 

 in habits and form. Unlike any of the previous ones, it is apparently peculiar to 

 low elevations, occurring either on the sea-shore or within the altitude of about 

 900 feet. On the flat ledge of ground overlooking the Praya Fornioza I have 

 captured it in the utmost abundance, from beneath stones ; as also in dry spots on 

 the cliffs to the eastward of the town, immediately beyond the Ribeiro de Sao 

 Goncalvo, — the highest position in which I have hitherto observed it. 



397. Helops Portosanctanus, Woll. (Tab. XII. fig. 9.) 

 H. angusto-oblongus piceo-ferrugineus nitidus vel opacus leviter et minus confertim punctulatus, 

 prothorace subquadrato, elytris plus minusvc obsoletissime crenato-substriatis, antennis pedi- 

 busque testaceis. 

 Long. Corp. lin. ^\-4^. 



Habitat Portum Sanctum, prope maris litus atque in aridis subinferioribus, tempore hiberno et 

 vernali vulgatissimus. 



H. oblong, comparatively narrow and subcylindiical, usually of a dark piceo-ferruginous (though 

 sometimes a little paler), either shining or opake (and with all the intermediate states), — which 

 however appears to be in no way a sexual character. Head coarsely punctured. Prothorax and 

 elytra much more finely punctulated than the head, and less closely so than in any of the previous 

 species : the former rather convex, subquadratc, and with the sides more or less rounded : the 

 latter very obsoletely crenate-striated (the strife being always far less perceptible than those of the 

 H. cinnamomeus, and sometimes altogether obsolete) ; the interstices with their punctures (though 

 very variable in size) always rather smaller than those on the prothorax, and without any appear- 

 ance of tubercles. Legs and antenna pale diluted testaceous. 



A very remarkable species ; and, although more changeable in surface than any 

 here described, retaining nevertheless many peculiarities which will readUy distin- 

 guish it, in aU its states, from the remainder of the Selopidce with which we have 

 to do. Its narrower and more oblong outline, in conjunction with its less thickly
