About thirty species are known. Knowledge of the group is 

 still very imperfect. A larva has been found of a most remarkable 

 nature that probably belongs to it ; it was described under the 

 name of NecrophUus arenarius, and considered to be a fully- 

 developed Insect. This larva occurs in the tombs and pyramids 

 of Egypt where sand has accumulated. The perfect Insects of 

 the genus Nemoptera are, however, found in open places amongst 

 bushes, and flit about in a very graceful manner. Several species 

 are found in Southern Europe and the Mediterranean region
