CANARIAN COLEOPTEBA.

as on the opposite Cumbre, above the Agua Mansa, — on both of which 

 I met with it in profusion during May 1859, and on the former of 

 which it has lately been captured by Dr. Crotch. 



The L. crassifrons may be known by its convex head and thick, 

 subtriangular, coarsely punctured rostrum ; by its convex and rather 

 densely punctured prothorax (on which the larger and smaller systems 

 of punctures are strongly expressed); by its somewhat oblong-oval 

 elytra (which have their humeral callus and the punctures of their 

 interstices obsolete) ; and by its surface being more or less clothed 

 with robust, yellowish- brown, and but faintly metallic, piliform scales. 



538. Laparocerus scapularis, n. sp. 



L. fere ut L. crassifrons, sed multo minor, rostro graciliore (vix lon- 

 giore) et minus tiiangulari, oculis minoribus rotundatioribus et 

 paulo magis prominentibus, prothorace minus profunde sed magis 

 confertim punctato, elytris vix magis pilosis necnon ad apicem ip- 

 sum sensim magis deflexis, antennis pedibusque brevioribus et 

 saepius paUidioribus, illarum scapo magis curvato, horum tarsis 

 sensim angustioribus. — Long. corp. lin. 2-1—3. 



Habitat Teneriffam excelsam, in iisdem locis ac prsecedens : sub 

 lapidibus et scoriis inter arbusculas Spartii nubigence humi jacentibus 

 etiam ultra 9000' s. m. ascendit. 



In habits the L. scapularis does not differ from the L. crassifrons, 

 with which indeed it is found in company — on the elevated Cumbres 

 of Teneriffe, from about 6000 to at least 9000 feet above the sea. 

 It may, however, be easily recognized from it by its considerably 

 smaller bulk ; by its rostrum being slenderer, and (though scarcely 

 longer) rather straighten' at the sides, or less triangular; by its eyes 

 being smaller, rounder, and more prominent ; by its prothorax being 

 less deeply and more closely punctured ; by its elytra being usually 

 perhaps a trifle more pilose, and just perceptibly more decurved at 

 their apex ; and by its antennae and legs being shorter and generally 

 paler, with the scape of the former more curved, and the feet of the 

 latter distinctly narrower. I took it less abundantly than the L. 

 crassifrons ; and I have three specimens now before me which were 

 captured on the Canadas by Dr. Crotch.
