CANAIIIAN COLEOPTERA. 379 



found likewise by Mr. Gray. It occurs principally in dry spots at 

 low and intermediate elevations — often abounding around S'" Cruz 

 and Orotava in TenerifFe ; as also near Las Palnias and throughout 

 the region of El Monte in Grand Canary. 



Genus 219. BRACHYDERES. 

 Schonherr, Cure. Disp. Meth. 102 (1826). 



578. Brachyderes rugatus, n. sp. 



B. elongatus, niger, nitidus, pube subcinerea demissa parce tectus ; 

 capite prothoraceque punetatis, hoc in disco obsolete canaliculato 

 et ibidem levius punctato ; elytris ellipticis, levissime substriato- 

 punctatis, interstitiis minutissime subasperato-punctulatis et trans- 

 versim rugulosis ; antenuis pedibusque rufo-piceis. 



Mas elytris angustis, vix profundius striato-punctatis, apice obtuse 

 rotundatis. 



Foem. elytris multo latioribus, apice lateraUter subcompressis acuti- 

 uscuhs. — Long. corp. lin. 41-6. 



Habitat Palmam, super folia floresque Phii canariensis in elevatis 

 degens. 



Both of the Brachyderes here described are attached to the foliage 

 and flowers of the Pinus canariensis, at loftj altitudes ; and although 

 they are certainly veiy closely related inter se, I can hardly suppose 

 them to be insular modifications of the same species. The B. rugatus 

 abounds in the old Finals of Palma — where I observed it in consi- 

 derable numbers, during June 1858, in that extensive one which 

 clothes the region from the elevated plains known as " Los Llanos " 

 up to the edges of the great Caldeira. It is, on the average, a trifle 

 larger than the sc^dpturatus, and is more thickly beset with a some- 

 what paler and more decumbent pile ; and its elytra are much more 

 finely punctate-striated, with their interstices rather more densely 

 transversely-rugulose . 



579. Brachyderes sculpturatus, n. sp. 

 B. prsecedenti similis, sed vix minor, pube paulo magis robusta et 

 erecta parcius obsitus (pube praesertim ad apicem necnon per su- 

 turam saepius submetallica) ; elytiis in utroque sexu multo pro- 

 fimdius striato-punctatis, interstitiis minus dense transversim -ru- 

 gulosis, in sexu foemineo ad apicem ipsissimum vix minus acutis. 

 — Long. Corp. lin. 4-5^. 



Habitat in locis similibus ac praecedens, sed in montibus Canarise 

 et Tenerifiae (nee Palmae). 



Whilst the last species occurs in the ancient Pinals of Palma, the 

 present one I have observed in those of Grand Canary and Teneriff'e
