shorter and sinuated along its extreme base, and with its elytra 

 (the interstices of which are not raised) less deeply punctured, and 

 without any additional setae at their apex. Its limbs, moreover, 

 are considerably darker than is there the case. Its structural 

 characters are quite those of Leiparthrum, the proportions of its 

 4-jointed tarsi and funiculus being precisely similar to what ob- 

 tains in the other members of the group. Its front-tibiae, however, 

 are not entirely unarmed, — there being two short, obtuse teeth on 

 their outer edge. I have much pleasure in dedicating it to its 

 discoverer, whose recent explorations in the Canarian archipelago 

 have added some valuable material to my collection.

In my Paper on " The Atlantic Cossonides," lately published in 

 the " Transactions of the Entomological Society of London," I 

 gave full diagnoses of the various Canarian Phlceophagi, — observ- 

 ing that the present species differs from its Atlantic congeners by 

 having, amongst other features, a scarcely visible scutellum : in- 

 deed, in the generality of specimens it is quite impossible, even 

 beneath the microscope, to detect the smallest traces of a scu- 

 tellum ; though occasionally one may just be observed, in the form 

 of a minute transverse plate. The P. caulium is further remark- 

 able for its excessively deep and coarse sculpture, for its tibiae
