 this family by the extreme minuteness of the terminal joint of the 

 palpi, having at the same time the antenna not geniculated, and the 

 anterior tarsi not dilated in either sex : the head is small, suborbicu- 

 late ; the eyes are also small : the thorax dilated and rounded behind ; 

 and the abdomen long, and considerably attenuated towards the 

 apex, which is acute. The species frequent the coasts.
