322 CANARIAN COLEOPTEKA. 



(utrinque leviter impresso necnon apice in medio fovea parva, ante 

 carinulam tenuissimam brevissimam posita, notato), scabroso-rti- 

 guloso (vix piinctulato) et tuberculis magnis parcissime adsperso, 

 albido trUincato (linea media tenuiore, recta), per basin bisiuuato ; 

 elytris convexis (versus scutelliim depressioribus), le\iter punctato- 

 ■ striatis et tiiberciilis magnis irregularibus remotis (prsesertim antice 

 necnon in limbo) asperatis, singulis (ad apicem \'ix prodiictis) 

 fasciis 4 valde obKqnis albidis (longe ante suturam terminatis) or- 

 natis ; antennis (sensim pone apicem rostri insertis) basi jiiceis. — 

 Long. corp. lin. 7. 



Habitat TenerifFam, mihi non obvius : specimen unicum tempore 

 vernali a.d. 1848 cepit Rev''"' Dom. W. J. Armitage, cnjus in memo- 

 riam (heu ! deflendam) nomen trivialc proposui. 



The unique example from wliich the above diagnosis has been 

 compiled was captured in TenerifFe during the spring of 1848 by my 

 lamented friend and associate, the late Rev. W. J. Armitage, the spe- 

 cies having altogether escaped my own observation in these islands. 

 Its general appearance is almost as much that of a LLvus as of a 

 Cleomis, so that it is not entirely evident to which group it should be 

 assigned*. It may easily be lyiown from the other Canarian CJeoni, 

 as yet detected, by its cylindric-fusiform outline ; and by its dark 

 and rather shining surface being roughened ^^dth large, remote tuber- 

 cles (some of which are transversely subconfluent, so as to iorva. plicai 

 on the anterior portion of the elytra) and sparingly ornamented with 

 white scales. These last arc condensed on the prothorax into three 

 lines (the central one of which is straight and narrow, whilst the 

 lateral ones are broad and irregular), and down the disc of each of 

 the elytra into four very oblique fasciae (which are greatly abbrevi- 

 ated both towards the suture and margin). Its antennoe are inserted 

 somewhat further from the apex of its (cyHndrical, subarcuated, 

 miinitely punctured, and on either side longitudinally-impressed) 

 rostrum than is usual with the true Cleoni ; its prothorax is compa- 



* Of the close affinity of these two genera, although widely separated in Sclion- 

 herr's most unnatural system, there cannot be the smallest doubt ; and it is there- 

 fore satisfactory to find that Lacordaire has recently, in his admirable volume, 

 placed tliem in juxtaposition. Indeed M. Jekel, who examined the present insect 

 for me very critically, returned it witli the following observation : "As a Cleonus 

 nothing to my knowledge aiaisroaches it ; but it is allied to some Lixi from con- 

 tinental Africa (from Senegal down to the Cape of G-ood Hope) in which the ros- 

 trum is short. It seems to me that nobody has yet been able to trace out a real 

 line of demarcation between Lixu» and Clcomis ; and the transposition of many of 

 the species, even by Schonherr himself, proves how difficult it is to do so, and how 

 much the group requires revision. After a close inspection of the example which 

 you have sent me, I have been much struck with its Lixus-Ukc appearance ; and 

 (if a Lixus at all) I would place it near to the L. vefiila, Fab., and other cognate 

 forms."
