Whilst the preceding P/ilceophagits c\])])caYS to be peculiar to tlie 

 Etip/iorhia-stems of Fuerteventura and Lanzarotc, the present 

 one, so far as I have hitherto observed, is attached to the Laiu'els 

 ol'^lYMieriiTe and Palma, in the decayed trunks of which it often 

 aboiuids, at intermediate and lofty elevations. At first sight the 

 wliole of these Canarian species are scarcely recognizai)le from 

 each other ; but, when placed beneath the jnicroscope, the present 

 and two following ones will be found to have very distinct scu- 

 tella — which would sufiice, even of itself, to separate them from 

 the /'. caulium and piceus. Amongst other characters, however, 

 I may mention that the P. laitritieus has its elytra (which are per- 

 haps a trifle less ovate) more deeply sculptured than those of any 

 of its allies, the punctures of which (except as compared with 

 those of the P. simplicipcs) are perceptibly larger and the inter- 

 stices uiore convex ; its antenna', also, are slightly elongate and 

 pale, with their funiculus-joints somewhat lax inte)- se, and their 

 club rather acute, and its third tarsal-articidation is almost (if not 

 quite) as much expanded and bilobed as in the last s])ecies. 



The var. ft (which would seem to be peculiar to Palma) may 

 possibly be distinct, in reality, from the typical form of Teneriffe; 

 nevertheless, its differential characters are so small that I have 

 thought it better not to isolate it ; it differs in having its pro- 

 thorax (when viewed beneath the microscope) sub-alutaceous, 

 with the punctures rather smaller and more dense, in its elytral 

 interstices being somewhat less convex, and its antcnnal-club a 

 trifle more abbreviated and abrupt, — in most of which respects 

 (though not in all) it is somewhat intermediate between the tijpical 

 laurincus and the ajjims: nevertheless, in the paleness of its an- 

 tenna} and its principal characters (and I believe, also, in its 

 habits), it has, I think, more in common with tin? former than with
