 lapidibus in aridis, passim. 



I believe that the Canarian Cleonus here referred to is correctly 

 identified with the tabidus of Olivier, a species which is not uncom- 

 mon in southern Europe. At any rate it accords precisely with the 

 description given in Schonherr's work, and also with a Sicilian ex- 

 ample Avhich I have received from M. Jekel. Nevertheless I should 

 add that it agrees almost equally with the diagnosis of the excoriatus, 

 as well as with two specimens from northern Africa, thus named, 

 which M. Jekel has likewise communicated to me. Indeed so exactly 

 do these supposed types tally inter se, that I have not the slightest 

 hesitation in regarding them as conspecific with each other ; and as 

 there is absolutely no character whatever, that I can detect, in Gyl- 

 lenhal's long descriptions by which the two can be separated, I should 

 doubt their being in reality distinct. Be this, however, as it may, I 

 am inclined, on the whole, to refer the Canarian insect to the tabidus 

 — which moreover, being prior in publication to the earoriatus, will be 

 the name which must eventually be retained if the two should here- 

 after be acknowledged as identical. 



The C. tahidus (as here determined) is often abundant in diy spots 

 of low and intermediate elevations, in Lanzarote, Fuertevcntura, Grand 

 Canary, and Teneriffe ; but I have not as yet observed it in the three 

 western islands of the Group. My Lanzarotan examples are princi- 

 pally from Yaiza and the \acinity of Haria, the Fuerteventuran ones 

 from Puerto de Cabras, the Grand Canarian ones from Las Palmas 

 and Arguinjguin, and the TenerifFan ones from Lagima. In Lanza- 

 rote it was taken also by M. Hartung, and is evidently the Cleonus 

 referred in his Catalogue (which was prepared for him by Dr. Heer) 

 to the obUquus, Illiger — a species, however, from which it is totally 

 removed, not merely in fades and markings but in several of even 

 its structural details (amongst which the shape of the eyes should be 

 especially noticed). From Fuertevcntura and Teneriffe it has also 

 been sent by the Barao do Castello de Paiva.

 I believe that the present group is truly distinct from Cleonus,
