Three males, one imperfect. This insect is one of three 

 small, snbopaqiie, closely allied, plumbeous forms with 

 immaculate elytra captured by Dr. Marshall at Salisbury, 

 the males differing greatly inter se in the structure of the 

 head and antennje, the flavous portion of the head being 

 sub(]uadrate in the present species. The general shape is 

 that of a Cicindela.
