Above brassy, more rarely blue-black. Head deeply striated 

 and carinated in front, smooth behind; palpi and antennae 

 black, basal joints of the latter red beneath. Thorax broadest 

 in front with the anterior margin produced in the middle so as 

 to form a small projecting point or angle, the sides obliquely 

 narrowed and only slightly rounded, a little sinuated behind 

 (PL I. f. 6) and curved outwards so as to form the basal angle, 

 the basal margin slightly excavated in the middle, the disk with 

 the dorsal furrow terminating behind in a triangular punctured 

 depression, the base with two fovese and all the margins strongly 

 punctured, leaving a smooth space in the middle on each side 

 the central furrow. Elytra oblong, much wider than the thorax, 

 not contracted in front, but with the shoulders merely a little 

 rounded, sides somewhat parallel, apex rounded, each elytron 

 with one punctured stria next the suture, the punctures of 

 which disappear before the apex, but the stria itself is carried 

 to the extremity, then a wide longitudinal polished space, then 

 seven other punctured strise, the marginal one finer and more 

 remote from the other six, all which disappear or become obsolete 

 before the extremity, across the third and fourth strise there is 

 also a single deep impression ; underside of the body and legs 

 bronzed black, tibise sometimes testaceous externally. Length 

 2^ lines. 



LTpon examination of the examples of N. Newmanii and 

 metallicus lent to me by Mr. Waterhouse, I refer them to this 

 common species. 



2. N. palustris : ceneus nitidus ; thoracis limbo punctato, la,te- 



ribus rotundatis ; elytris extus striatis, striis punctatis 

 apicem versus evanescentibus; antennis basi, tibiisque 

 testaceis.
