One specimen. Differs from N, mellitus of Eastern Anierica 

 by the more robust and nearly smooth prothorax, which is 

 scarcely sinuated on the sides, and by the elytra being much 

 more deeply impressed near the tip.

A fully matured specimen from Vancouver's Island evi- 

 dently belongs to the same species as the pale-coloured speci- 

 men from California previously described by me. It is allied 

 to the Alaskan L. Frankenliaeuseri and macilenta^ and, apart 

 from differences in the colour, which I regard as of no impor- 

 tance, only differs from them by the larger size, and the convex 

 part of the disk of the prothorax not being foveate on each 

 side of the dorsal channel.

 less elongated antennje, and by the more distinctly emarginated 

 eyes. I am inclined, in view of the great differences in colour 

 observed in certain species of Acmceops, to regard these three 

 forms as merely varieties of one species. They belong to a
