S. pulchellus, Herbst. (i-Iuavlatus, 111. ; s.g. Nephus, Muls.). 

 Oval, moderately convex, pubescent, black, witli the labrum, antennae 

 and legs, and four spots on the elytra testaceous or reddish-testaceous ; 

 the anterior pair are larger, oblong, and oblique, and situated near 

 shoulders, and the posterior pair, situated before apex, are smaller 

 and slightly lunate ; the elytra are less finely and more deeply punc- 

 tured than thorax ; legs yellow, posterior femora often darker. L. 

 1|-1| mm. 



Very rare ; the species was introduced by Mr. G. R. Waterhouse in 1863 on two 

 doubtful specimens from Kirby's collection ; the only authentic British example 

 appears to be one taken in Kent, which is in Mr. Rye's collection. 



S. Redtenbacheri, Muls. (s.g. Nephus, Muls.). A very small 

 species, of an elongate-oval shape, moderately convex, clothed with pale 

 pubescence, black with an oblique band of a reddisb or reddish-yellow 

 colour on each elytron ; antennas, mouth-parts and legs entirely testaceous ; 

 the femora, however, .are occasionally dark ; elytra finely but somewhat 

 distinctly punctured ; the size and shape of the elytral band is variable. 

 L. 1-1^ mm. 



A specimen from Mr. Wilkinson's collection, now in the possession 

 of Mr. Mason, was returned to me by M. Brisout in 1882 as this insect, 

 and Mr. Mason subsequently found several others in the same collection
