TACHINIDAE 
Clausicella setigera Thom. 
Plagiprospherysa parvipalis V. d. W. 
Senotainia trilineata V. d. \WV. 
Goniochaeta plagioides Twns. 
Aldrich says of this: ‘‘New to me, and one of the few that 
Coquillet did not inelude in his Revision. This is a big find.’’ Town- 
send described this from Las Cruces, N. M. 
MUSCIDAE 
Chrysemyia nigripes \Wheeler 
Pseudopyrellia cornicina Fab. 
Myiospila meditabunda Fab. 
Muscina stabulans Fall. 
The above four flies were very common. 
ANTHOMYIDAE 
Hylemyia alcathoe Wk. 
Pegomyia affinis Stein 
Caricea nana Zett. 
The above three flies are common in vegetation back of beach. 
Fucellia costalis Stein 
This species is quite common on decaying kelp. They are large, 
quick flies. They seem to be at least partially predaceous in habit, 
as I have seen them pounce upon weakened sand-hoppers and by 
their numbers soon overcome them. 
Fucellia rufitibia Stein 
(Figure 89) 
There are myriads of this fly swarming over the decaying kelp. 
They are found with F’. costalis, which, however, they vastly out- 
number. They are slow of flight and easy to catch. 
PHYCODROMIDAE 
Coelops frigida Fall. 
Common on decaying kelp. 
SAPROMYZIDAE 
Sapromyza flaveola Coq. 
Abundant in vegetation near beach. 
Sapromyza fraterna Lw. 
Occasional with the last species.
