CANAEIAN COLEOPXEHA. 457 



Whether the Gomeran "insect, which I have treated as a " var. /3 " 

 of the present one, and which was taken by Mr. Gray and myself 

 (near San Sebastian), during February 1858, and subsequently by 

 the Rev. R. T. Lowe (at Hermigua), should not rather be regarded 

 as a distinct species, I am somewhat doubtful ; but I believe that its 

 differential characters are scarcely of sufficient importance to warrant 

 the conclusion that it is more than a mere insular phasis of the H. 

 brevicoUis. It is, however, a little more convex and ovate in outline 

 (occasioned by the elytra being a trifle more drawn downwards, or 

 less acuminated, at their apex), very perceptibly more shining, and 

 with the punctation perhaps not quite so " obsolete " ; the basal angles 

 of its prothorax, also, are better defined, and more strictly right angles ; 

 and its antennse and legs are sensibly thicker. 



693. Hegeter abbreviatus. 



//. latus, curtus, breviter oblongo-ovalis ; capite prothoraceque sub- 

 opacis, dense et (praesertim illo) distincte punctatis, hoc transverse 

 'angulis posticis vix obtusis ; elytris ad basin truncatis (vix bisi- 

 nuatis), subnitidioribus, paulo subtilius punctulatis ; antennis pe- 

 dibusque subgracilibus, nigro-piceis. — Long. corp. lin. 2^-3. 



Hegeter abbreviatus, Bridle, in Webb et Berth. (Col.) QG (1838). 



Habitat in lauretis excelsioribus Canariae Grandis, rarissimus. 



This is one of the best-defined of all the Hegeters hitherto detected, 

 its short and broad, oblong- oval outline, combined vrith its distinctly 

 and densely punctulated surface (the head and prothorax being sub- 

 opake, whilst the elytra, which are straightly truncated at their base, 

 are rather more shining), being abundantly sufficient to characterize 

 it. It would appear to be exceedingly scarce, or at any rate local, 

 the only spot in which I have observed it being the laurel-district 

 (which forms a portion of the ancient forest of El Dorames) between 

 Guia and Osorio in Grand Canary — where, on the 21st of April 1858, 

 I captured eight specimens, from beneath damp stones, at the edges 

 of the mountain-road below the house of General Morales. 



694. Hegeter costipennis, n. sp. 



//. oblongo-ovatus, crassus, opacus ; capite prothoraceque (ijrsesertim 

 hoc) impunctatis, hujus anguHs posticis rectis ; elytris granulatis, 

 singulis longitudinaliter 3-costatis, costa interna minus elevata. 



Variat (an potius distinctio sexualis ?) subnitidus, elytrorum granulis 

 minus distinctis. — Long. corp. lin. 4-5. 



Habitat in montibus Canariae Grandis, rarissimus, sub lapidibus. 

 A most remarkable Hegeter, readily known by its large and thick 

 body, opake surface, and granulated elytra, which have thi"ce elevated
