palpus of this insect. The antennae are slender, and rather 

 thicker at the tip than at the base. The head has a deep

 Nehria brevicollis, a figure of which is given on Woodcut III.

genus, their length exceeding half an inch, and sometimes reach- 

 ing three-quarters of an inch. In these insects the antennae are 

 long and slender, and the mentum is divided into three distinct 

 lobes, the central lobe being cleft, as it were, into two. The 

 thorax is heart-shaped and abruptly cut off both in front and 

 behind, the basal angle being straight. The wings are well de- 

 veloped. Most of these Beetles belong to the maritime insects.
