510 INSECTA MADERENSIA. 



the Canaries that they attain their maximum, — where no fewer than twelve have 

 been already recorded l^y "Wel^b and Berthelot, and where it is far from unlikely 

 that many more still remain to be detected. Thcv are insects of a verv sresarious 

 nature, and of sedentary modes of life, — congregating in caverns and beneath stones, 

 especially near the sea-shore, and avoiding the light. The common H. elongatus 

 indeed is occasionally to be met with (in the same manner as the Blapsidce) in and 

 about houses ; but their normal range is decidedly at a distance from habitations, 

 — in which respect they partake a good deal of the character of Helops.

 H. ater subopacus impunctatus subdepressus, capite subtus sulco brevi longitucHnali profunde im- 



presso, prothorace subquadi-ato ad angulos acuto, elytris striatis, antennis pedibusque longioribus, 



tibiis subglabris.

Habitat sub lapidibus et in cavcrnis Maderae Portusque Sancti, prjesertim per oram maritimam, toto 

 anno frequens : in cavcrna quadani basaltica mox infra summum montem Portosanctanum Pico 

 d'Anna Ferreira dictum sitii mense Aprili a.d. 1849 copiosissime collegi. 



H. elongate-ovate (being widest behind the middle), deep black, almost opake (especially the head 

 and prothorax), impunctate and somewhat depressed. Head underneath with a very deep longi- 

 tudinal (though abbreviated) impression in the centre, at the base of the mentum. Prothorax 



the Canaries, and since its remote locality renders it desirable that it should be distmguished, I subjoin 

 the folloiiving diagnosis which may serve to separate it from its allies : 



Hegeter latebricola, TVoU. 

 H. ater subnitidus minute punctulatus subconvexus, capite subtus vix impresso, prothorace transverse ad 

 angulos minus acute, elytris vix substriatis, antennis pedibusque brevioribus, tibiis le^^te^ setulosis. 

 Long. Corp. Ha. 5^-7. 



Habitat in insulis " Salvages," a Dom. Leacock nuper conunuuicatus. 



H. oblong-ovate (being widest about the middle), deep shining black, closely and minutely punctulated 

 aU over, and somewhat convex. Head beneath with scarcely any indication of the impression which 

 is so deep and apparent in the INIadeiran H. elongatus. Prothorax transverse, being much shorter 

 than in that species ; also with the sides slightly more roimded and the angles not quite so acute. 

 Elytra with the faintest possible indications of stria; (which are sometimes however altogether 

 obsolete). Antennm and legs shorter than in the //. elongatus; the latter ^vith tlieir tibia- minutely 

 setulose. 



It was discovered by T. S. Leacock, Esq., of Funchal (on the " Great Piton "), during his late expedition 

 to the Salvages ; to whom I am indebted for a fine series of specimens, in a very perfect state.
