near margins ; elyti-a short, truncate, strongly striate, inter- 

 stices convex, minutely punctate. Opaque, piceous-black; elytra 

 narrowly margined with brown; legs pale brown. 



Head and prothorax as in iV. chaudoiri, SI., only the basal 

 curve of prothorax shorter, the sinuosities behind the posterior 

 angles more decided, and the base itself more ti'uncate. Elytra 

 short, truncate, widest behind middle (2'8 x 2-3 mm.), a little 

 narrowed to base; sides rounded; humeral angles rounded; striae 

 deeply impressed, minutely punctate; interstices convex, finely 

 punctate on each side near strise — elytra in other respects 

 agreeing with those of N'. chaudoiri. 



Length 5-6, breadth 2-2-3 mm.

Differs from N. chaudoiri by its shorter more depressed elytra, 

 with the interstices finely punctate, &c. 



Genus Pentagon ICA. 



Baron Chaudoir, when treating of this genus, made the 

 following note on its position :—"Je crois que M. Bates a ete 

 dans le vrai en les placant dans un groupe special sous le nom de 

 Pentagonicince (Trans. Ent. Soc. Lond. 1873, p. 320)."* Com- 

 menting on this Dr. G. H. Horn says : — " This is certainly an easy 

 settlement of the difficulty, more particularly as no characters are 

 asi-igned to the group."!

Genus Scopodes. 



The genus Scopodes has been considered by the late H, W. 

 Bates to form a distinct subfamily; and Chaudoir has made the 

 following observation on the position of Scopodes and Actenonyx, 

 a Xew Zealand genus : — ^" lis doivent former un groupe a part 



voisin des Lachnophorides; toutefois je n'emets encore 



cette opinion qu'avec doute."J
