178 CANARIAN COLEOPTERA. 



— the foiir posterior tibiae being densely armed with long spinules, 

 and with their apical spurs largely developed ; and by its feet being 

 much incrassated, subcorneal, and more powerfully spinose beneath 

 than is the case with the generality of the Saprini. 



The 8. erosus appears (like the following species) to be of maritime 

 habits, as indeed the very robust structure of its greatly thickened 

 four hinder legs, with their densely spinulose tibiae and feet and 

 somewhat largely developed apical spurs, would seem to indicate. 

 My six specimens were all captured, from beneath marine rejecta- 

 menta, on the sandy beach at Corralejo, in the extreme north of 

 Fuerte Ventura.

Although very closely allied to the European 8. maritimus ( =sahu- 

 losus, de Mars.), it certainly would not be safe to refer the present 

 Saprinus to that species. It may be known from it by its entire 

 surface having a more or less conspicuous aeneous tinge (though oc- 

 casionally picescent posteriorly), instead of being black ; by its elytra 

 having their striae rather shorter and considerably finer, and their 

 punctation denser and less coarse, and extending over a larger por- 

 tion of the posterior disc ; by the three apical teeth of its anterior 

 tibiae being perhaps a trifle longer ; by its pronotum being rather 

 more narrowly punctured along its extreme base ; by its presternum 

 being somewhat more imeven, or sinuated, with its apex a little more 

 prominent (or downwardly directed), and with its lines almost par- 

 allel (or not quite so approximated in the middle, and therefore not 

 so perceptibly divergent before the middle) ; and by its mesostemum
