5. S. ater, Kug., 1. c. VI., 62. 



Sea banks near Blyth and Hartley. Bare. 



6. S. lividus, new sp. 



Suboval, convex, slightly shining, somewhat densely covered 

 with short griseous pubescence, finely and evenly punctured, livid 

 testaceous, the head and claws black, thorax and suture obscurely 

 fuscous. Length, half a line. 



Smaller, more oval, much more finely and evenly punctured 

 than S. discoideus, to small pale examples of which it bears a 

 superficial resemblance. 



I have seen only one specimen of this insect, which I took on 

 the sea banks near Hartley in April, and with which no descrip- 

 tion known to me fully agrees.
