346 CANARIAN COLEOPTERA. 



Habitat in montibus Canariae Grandis ; mense Aprili a.d. 1858 ex- 

 emplar unicuni in pineto quodam excelso regionis " Tarajana" dictse 

 deprehendi. 



In its narrow, elongate outline, its short, thick rostrum, and its api- 

 cally truncated prothorax, the specimen from which the above dia- 

 gnosis has been compiled somewhat resembles at first sight a Brachy- 

 deres ; nevertheless its longer antennae and dififerently formed scrobs, 

 in conjunction with the deeply excavated tip of its rostrum and the 

 excessively minute subhorizontal spine with which the inner angle 

 of its tibiae is armed, will of themselves at once remove it from the 

 members of that group. Amongst the Laparoceri it (or at any rate 

 the sex which I have examined) is remarkable for its slender, elon- 

 gate form and comparatively depressed, brownish-piceous surface ; 

 for its rostrum being short, thick, subquadrate, and densely and mi- 

 nutely punctulated, but only slightly channeled ; by its thick forehead 

 having a very deep longitudinal fovea between the eyes ; and by its 

 prothorax being rather abbreviated, much truncated (and faintly sub- 

 sinuate) along its anterior edge, and with the double system of punc- 

 tures comparatively dense and well defined. The individual described 

 from was taken by myself, during April 1858, in the lofty Pinal of 

 Tarajana, above San Bartolome, in the centre of Grand Canary.

Laparocerus crassifrons, Woll, Aii/i. Nat. Hist. xi. 220 (1863). 

 Habitat sub lapidibus scoriisque in regionibus valde elevatis Tene- 

 riffoe, usque ad 9000' s. m. ascendens. 



The present Laparocerus, which is most variable in stature, seems to 

 be peculiar to the lofty altitudes of Teneriffe which are characterized 

 by the presence of the Sparfmni nuhigetui (or " Retama "), above the 

 sylvan districts, and embracing from about 6000 to 9000 feet above 

 the sea. In such situations it abounds, beneath scoriae, on the ele- 

 vated Cumbre adjoining the Canadas, above Ycod el Alto ; as well
