Larva. Form long and slender. Spiracular. disk squarely truncated and surrounded by 

 five subequal lobes; paired lobes of disk heavily lined with black; a black mark running proxi-

Molophilus is a well-defined genus (including more than fifty species) 

 of small and usually dull-colored flies, which are found practically thruout 

 the world. 



The adult flies frequent shaded situations and may be swept from 

 rank vegetation in such places. The swarming habits of this group are 

 discussed later under the specific accounts. 



The immature stages of the various species are spent in wet earth. 

 In Europe, Molophilus obscurus (Meig.) (Beling, 1879:56) and M. ochraceus 

 (Meig.) (Beling, 1886:193-194) have been found in wet earth near running
