Habitat Canarienses (Lanz.\ ad marginem lacus ejus salini " Januvio" 

 dicti semel deprehensum. 



Likewise Lanzarotan, and unique, but of totally different habits to 

 the last species a single example having been captured by myself 

 at the edge of the salt lake of Januvio (which adjoins the south- 

 western coast), running rapidly over the mud in the hot sunshine.

Habitat Canarienses (Ten.), inter lapillos humidos ad margines 

 aquarum in inferioribus sese occultare delectans. 



A small and narrow Lathrobium of Mediterranean latitudes which 

 occurs sparingly, at a low elevation, in the Canarian Group. Tene- 

 riffe, however, is the only island in which it has hitherto been cap- 

 tured where I met with several examples of it, amongst wet 

 shingle, at the edges of a little pool in the Barranco Santo, near 

 S ta Cruz.

Habitat Maderenses (Mad.) et Canarienses (Ten., Gom., Palma), hinc 

 inde in humidis, praesertim intermediis. 



This European Lathrobium is rather common in Madeira proper, 

 where it occurs in damp places at most elevations ; but in the Cana- 

 ries, where it differs a little from the more northern type, it is 

 decidedly scarce. I have captured it in Teneriffe and Palma, and it 

 was found by the Messrs. Crotch in Gomera. 



The Canarian examples, which I hardly think can represent more 

 than a slight geographical variety of the species, seem to have their 

 head and elytra just perceptibly more developed, the latter being 

 almost (perhaps indeed quite) concolorous throughout (instead of
