Jfirst annual Report 



SOME DIPTERA OF LACUNA BEACH 



F. R. COLE 



Laguna Beach is an excellent collecting ground for Diptcra. The 

 hills and inland vegetation extend almost to the ocean in many places, 

 and with the varied topography and conditions, the insects are very 

 varied. The beach with its rocks, sand stretches, beach plants, and 

 decaying wrack, is swarming with Diptcra. A small, shallow brack- 

 ish water lagoon at the inner edge of the beach gave some interesting- 

 results in Diptcra, but Diptcra were collected on the rocks even to 

 within reach of the salt spray. 



The collection of this year is but a mere beginning. I spent only 

 a few weeks at Laguna, and a large part of this time was consumed 

 iu anatomical studies. Most of the flies reported in the present 

 paper are either peculiar to the beach itself, or are found in the 

 varied vegetation of the upper beach. 



Without extensive assistance from Prof. J. M. Aldrich of the 

 University of Idaho, it would have been impossible to present this 

 paper at this time. Messrs. Knab and lliue have also kindly made 

 determinations. The accompanying habit sketches of new species 

 will be amplified by drawings of anatomical details, during the coin- 

 ing summer.
