 but it has not yet been observed elsewhere*.

Pound in Madeira proper and Porto Santo, of the Madeiran Group ; 

 and I took a single specimen of it at Oliva in Fuerteventura, during 

 my second visit to the Canaries. It occurs for the most part in 

 rather low situations, and often amongst plants of the Arundo donax ; 

 but whether it is actually attached to that gigantic reed, I have not 

 sufficient evidence for deciding. 



828. Lixus vectiformis. 



Lixus vectiformis, Woll., Ins. Mad. 351 (1854).

Habitat Maderenses (P to S to \ rarissimus ; in aridis calcariis inferi- 

 oribus specimen unicum collegi. 



A single specimen of this Lixus, which was taken by myself 

 (during December 1848) in Porto Santo of the Madeiran Group, is 

 all that I have yet seen. It was found in a dry calcareous spot, of 

 a low elevation, on the Campo Debaixo. It has much in common 

 with the L. Chawneri ; but (so far as I can judge from a solitary 

 example) it appears to be considerably smaller, somewhat narrower, 

 and a trifle more pubescent; its rostrum is relatively shorter; its 

 elytra are more lightly and finely punctate-striate, as well as a little 

 more acuminated (separately) at their apex; and its legs are less 

 thickened. 





* The L. ckeiranfhi belongs rather to an Algerian type, and is a good deal 

 allied to the L. Wagneri of Lucas. It may readily be known, however, from 

 that insect by its larger size, and by its coarsely and regularly seriate-punctate 

 elytra ; whereas in the latter insect the elytra have only the stria 1 on either side 

 of the suture deeply impressed, the remainder being extremely fine and almost 

 obsolete. The cheiranthi likewise has its rostrum a little thicker than is the case 

 in the Wagneri, as also rather more shining, more finely punctured, and totally 

 unkeeled; its prothorax is somewhat more roughly sculptured, or variolose, and 

 with the minute intermediate punctules coarser ; and its pubescence is altogether 

 more robust.
