CANAEIAN COLEOPTEKA. 119 



pimcturecl and more laterally compressed in front, and by its elytra 

 being less acute behind, with their striae rather deeper. 



194. Ehizophagus subopacus, n. sp. 



11. subdepressus, rufo-ferrugineus, subopacus, minute alutaceiis ; ca- 

 pite convexo, dense punctulato ; prothorace oblongo, ad latera vix 

 subrotundato, postice sensim angnstiore, angnlis anticis rotundatis, 

 obtusis, leviter et sat dense punctulato, in disco deprcsso ; elytris 

 fusiformi-parallelis, levdter punctato-striatis, per suturam obsolete 

 obscurioribus ; antennis breviusculis. — Long. corp. lin. 1|-1|. 



Habitat Palmam, in locis similibus ac praecedens, sed rarior. 



The rather flatter and less shining surface of this species (which, 

 under a high magnifying power, is minutely and densely alutaceous), 

 its slightly smaller size, its more finely and more closely punctulated 

 prothorax, which is relatively somewhat shorter, more depressed on 

 the disc, more perceptibly narrowed behind and rounded in front 

 (causing the sides to be less straight), and with its anterior angles 

 more obtuse, combined with its more lightly striated elytra, rather 

 darkened suture, and perhaps somewhat shorter antennae, will suffice 

 to separate it from the R. pinetorum. It is very much rarer than 

 that insect ; for out of 89 specimens of Canarian Rhizopliagi which I 

 have just examined, four only belong to it. They were captured by 

 myself in Palma, during the spring of 1858, — from beneath the rotten 

 bark of a Pinus caimriensis high up in the Barranco above S*" Cruz. 

 That they are no local modification peculiar to that island is evident 

 from the fact that I took them in company with the last species.
