and even if some do come, there is very little fear that methods of 

 controlling them will not be found. Many of the insects that are

A NEW FLY OF THE FAMILY PHORID.'E FROM 



CALIFORNIA. 



BY T. D. A. COCKERELL, BOULDER, COL. 



When recently (August, 1915) at La Jolla, California, I 

 captured on the grounds of the Scripps Institution for Biological 

 Research a Phorid fly remarkable for its relatively large size, and > 

 interesting to me on account of the armature of its legs, which 

 recalled one of the fossil species from Florrissant. The species is 

 new, and may be called: 



Dohrniphora gaudialis, n. sp. 



9 — Length about 4 mm., wings over 3.5 mm.; dull black, the 

 front and thorax above anteriorly somewhat polished ; third an- 

 tennal joint ferruginous, blackened above; palpi clear bright red, 

 the spines strong and black; wings pale greenish, the heavy veins 

 sepia; trochanters and immediately adjacent parts pale reddish; 

 knees reddened; anterior tibia? pale dull ochreous, and middle ones 

 brownish in front; tarsi dusky brownish; extreme apex of abdomen 

 light ferruginous. Head small ; proboscis stout, longer than head ; 

 arista long, minutely plumose; front with the usual strong bristles, 

 directed backward; ocellar region scarcely elevated; four scutellar 

 bristles, the posterior ones longest; halteres black; wings with the 

 two heavy veins running closely parallel, with a narrow interval 

 between them, the second one (third vein of authors) minutel v^ 

 branched before the apex, which is about half way from base to 

 apex of wing; costa bristly; first thin vein (fourth of authors) 

 gently and evenly curved, not bent, failing at extreme base; third 

 thin vein failing at end, but fourth reaching margin; hind femora 

 high and flattened; anterior tibiae with a bristle on inner anterior 

 face at about end of first third, and a row of minute black seta? on 

 apical half; middle tibicC with two very long bristles on basal part,
