 the hirticollis and alhoUrta. The markings in many 

 specimens are obsolete^ or have become effaced by age.

This species is remarkable for the length of its legs and 

 antennae. The thorax, in the female at least, resembles 

 in shape that of dorsdlis. The elevated white spots at 

 the base of the elytra distinguish it at once from all other 

 species. This species inhabits barren patches of earth on 

 salt marshes, where tlie tide occasionally flows, sometimes 

 in company with the hirticollis and albohirta. When 

 disturbed, they betake themselves to the high grass, which 

 they sometimes climb, to escape the rising tide, instead of 

 flying before its approach. The markings, as observed 

 by Mr, Say, are in many specimens nearly or quite obso- 

 lete, and they seem to disappear after death in many 

 cases. They more nearly resemble those of albohirta 

 than those of MrticoUis , to which Mr. Say compares 

 them. In the female, the elytra are somewhat widened 

 in the middle, and have a remarkable, oblique deflection 

 at the tips, which gives the appearance of a deep and 

 wide eraargination .
