 seashore species." (Fredk. Blanchard, in litt.}. Two speci- 

 mens, $ and 9 .. 



Maritima bears a slight resemblance to subfasciata Lee., but 

 differs from that species in many details ; in the present spe- 

 cies the form is more elongate, the prothorax proportionately 

 broader, the sculpture and color decidedly different, and the 

 elytral apices are non-serrate. 



I am indebted to Mr. Frederick Blanchard for the type ( $ ) 

 specimen, a cotype (?) is in Mr. Blanchard's collection. 

 Truro, Mass., is a town on Cape Cod peninsula.
