Family THEREVIM. 



Called "stiletto flies" by Comstock, because of their slender, pointed 

 abdomen. They resemble the robber flies, but have longer legs and are 

 more slightly built. They are also predatory, but the lips are broad and 

 fleshy, and they are not nearly so active as the "Asilidse." 



The larvae are long and slender, the segments constricted so that they 

 seem doubled in number, and they live in mold, fungi, rotten wood and 

 vegetable decay generally, feeding sometimes upon the material among 

 which they are found, sometimes upon such other insects as come in their 

 way. 



They can scarcely be said to be beneficial, for the prey of the adult 

 does not usually consist of insects that are harmful to the farmer.
