catecl to me by Mr. Janson), but is totally distinct in all its charac- 

 ters — of colour, outline, sculpture, clothing, proportions, and the in- 

 equahties of its surface. 



298. Thorictus canariensis. 



T. oblongus, rufo-piceus, nitidus, minutissime et parce punctulatus, 

 subtilissime (oculo fortiter armato) cinereo-pubescens ; prothorace 

 convexo, ad latera valde rotundato, angulis ipsis posticis oblique 

 impresso-marginatis ; elytris pieeis, antice subparallelis, in disco 

 valde convexis, ad basin linea mediii vix terminatis sed utrinque 

 breviter longitudinaliter subcostatis ; pedibus brcvibus. 



Variat capite prothoraceque plus minus rufescentioribus necnon re- 

 gione scuteliari plus minus obliquo-desihente. 



Var. ft. obsitus [an species distincta?]. Prothorace vix rufescentiore, 

 paulo distinctius punetato, versus utrumque latus obsoletissime 

 impresso ; elytris vix angustioribus, pube longiore erecta irroratis, 

 versus humeros paulo evidentius subplicatis. — Long. corp. lin. |— 

 vix. 1. 



Tliorictus canariensis, Woll.,Ann. Nat. Hist. (3rd series) ix.439 (1862). 

 Habitat insulas omnes Canarienses, sub lapidibus in formicarum 

 uidis hinc inde parum vulgaris. Var. ft ad locos editiores Tenerifiae 

 necnon ad Gomeram pertinet. 



In its general outhne and very minutely punctulated surface the 

 present Thorictus closely resembles the Sicilian T. grandieoUis* . It 

 differs from it, however, in being, on the average, of a distinctly darker 

 hue (though the head and prothorax, nevertheless, are more or less 

 rufescent), in having the sides of its pronotum a little rounder behind, 

 with the posterior angles more conspicuously depressed by an oblique 

 marginal band (which lops them off on their upper surface), in its 

 elytra being almost free from the minute central rim which terminates 

 the middle portion of their extreme base in that species, and with 

 the short subhumeral (posteriorly evanescent) costae perhaps some- 

 what less developed, and by its surface being very delicately and 

 sparingly pubescent ; whereas in the grandieoUis I cannot detect, 

 except at the lateral margins, the slightest trace of pile even under 

 the highest microscopic power. It is also very nearly allied, both in 

 aspect and hue, to the hicolor of Kraatz, from Greece and Sicily (vide 

 Berl. Ent. Zeit. 1858, p. 141) — for types of which I am indebted to 



* The Madeiran T. Westwoodil differs from the canmiensis in being paler and 

 a little more strongly punctured, in having its prothorax still more rounded at 

 the sides, and its scutellum (although very minute) quite traceable beneath a high 

 magnifying power, in the small elevated line with which the central portion of 

 the extreme base of its elytra is terminated being distinctly developed, and in its 

 antenna; and feet (particularly the liinder pair) being shorter and thicker.
