Habitat TenerifFam, a W. D. Crotch repertus. 



Although common at Madeira, I have not myself observed this 



European Stilicus at the Canaries ; but six examples of it are now 



before me which were captured by Dr. Crotch, during the spring of 



1862, in Teneriife.

Ohs. — S. hevigato Gyll. valde affinis, sed subangustior, capite 

 vix minore et etiam paulo subtilius punctulato, elytris brevioribus, 

 colore omnino subpallidiore, capite prothoraceque sensim nitidi-

Habitat Fuerteventuram, Canariam et Teneiiffam, inter lapillos ad 

 margines aquarum (vel fluentium vel stagnantium) parce degens. 



Apparently extremely rare, occurring amongst wet shingle at the 

 edges of pools and streams. In such situations I have taken it at La 

 Antigua in Fuerteventura, at Ai-guiniguin in Grand Canary, and in 

 the Barranco Santo (near S'* Cruz) of Teneriffe. It is possible that 

 it may be but a geographical modification of the European S. Icevi- 

 gatus, which at first sight it almost entirely resembles. It is, how- 

 ever, just perceptibly narrower, with its head not quite so much 

 developed and a little more finely punctulated, its elytra are appre- 

 ciably shorter, its entire colour is perhaps a shade paler, and its head 

 and prothorax are rather more shining.

S. angustissimus, subtilissime dense punctulatus, subopacus, minute 

 cinereo-sericeus, niger ; capite triangulari-subquadrato ; protho-
