752. Helops altivagans, n. sp. 



H. niger, nitidus, in elytris subopacus et obsoletissime subaenesccns ; 

 cajjite prothoraceque sat profunde et dense iDunctatis, illius clypeo 

 antice late et recte truncate, utrinque ante oeulos elevate et sub- 

 angulatim exstante, hoc convexo, ad latera rotundato subexplanato, 

 ante angiilos posticos obtusos vix sinuate ; elytris subellipticis (an- 

 tice paulo angustatis), leviter et tenuiter subcrenulato-striatis, in-

Habitat in montibus valde excelsis Tenerifffe, usque ad 9000' s. m. 

 ascendens. 



This Helops appears to be peculiar to almost the loftiest altitudes 

 of TenerifFe, the only four specimens which I have seen having been 

 captured by myself on the elevated Cumbre (overlooking the Caiiadas) 

 above Ycod el Alto, and on the opposite Cumbre above the Agua 

 Mansa. It may be known by its elytra being elliptical (or a good 

 deal drawn -in at the shoulders), in their having an exceedingly faint, 

 just perceptible, metallic tinge, and in being very lightly and finely 

 subcrenate-striated, with the interstices most minutely punctulated 

 and scarcely at all wrinkled transversely ; by its prothorax being 

 convex, considerably rounded at the sides, and but very slightly si- 

 nuated in front of the hinder angles (which are obtuse) ; and by its 

 clypeus being straightly and broadly truncated anteriorly, and rather 

 conspicuously raised and prominent (or subangulated) before either 

 eye. 



753, Helops elliptipennis, n. sp. 



H. prajcedenti nimis affinis, sed sensim aenescentior, punctura in ca- 

 pite prothoraceque paulo grossiore sed in elytris etiam subtiliore 

 (ajgre observanda) ; clj'peo antice minus recte truncate necnon ante 

 oeulos minus elevate et minus exstante ; prothoracis angulis pos- 

 ticis obtusioribus (sc. valde obtusis); elytris antice vix magis an- 

 gustatis, vix levins subcrenulato-striatis, interstitiis postice obsole- 

 tissime et remote seriatim tuberculatis ; antennis pedibusque ru- 

 fescentioribus ac paulo brevioribus. — Long. corp. lin. 4. 



Habitat Teneriffam, in sylvaticis parum elevatis degens. 



In its elliptic, lightly sculptured elytra and just perceptibly senes- 

 cent hue this species much resembles the preceding one, of which 

 it is barely possible that it may be but a permanent state peculiar to 

 the sylvan districts of a rather lower elevation. Unfortimately I 

 have but a single example, taken by myself at the Agua Mansa in 

 Teneriffe, to judge from ; but if it be normal of its kind, the H. elUp- 

 tipemiis differs from the altivagans in the above-mentioned pecu-
