CRYPTOPHAGID^E. 



Hitherto I have observed this interesting and truly indigenous 

 Silvanus only in the very elevated regions of Teneriffe which are 

 characterized by the presence of the Spartium nubigena, or 

 " Retama " from about 6000 to 9000 feet above the sea. It 

 occurs amongst the small stones and rotten sticks which accumulate 

 beneath the shrubs of the Eetama in the dry cindery districts, run- 

 ning with the utmost rapidity. In such situations I have taken it 

 on the lofty Cumbre (overlooking the Canadas) above Ycod el Alto, 

 as well as on the opposite heights above the Agua Mansa. It bears 

 a considerable resemblance, primd facie, to the European S. elon- 

 c/atus ; but the points (some of them structural ones) which imme- 

 diately distinguish it from that species have been fully alluded to in 

 my diagnostic remarks.

The European S. advena is not uncommon, under garden-refuse 

 and about houses, in Madeira proper ; but the only Canarian ex- 

 ample which I have yet seen was captured by the Messrs. Crotch, 

 during the summer of 1864, at Souzal in Teneriffe "out of thatch."

Two specimens of this European Cryptophagus, captured by the 

 late Mr. Bewicke near Funchal in Madeira proper, are all that I 

 have yet seen from these Atlantic islands. Like the C. cellaris and
