Family DEXllDJE 



Fig. 33. Thelaira levcozona Panzer. 



These are the "nimble flies" of Comstock. They are very 

 close to the tachinids but usually have longer and more slen- 

 der legs and the antennal arista plumose to the tip. The 

 larvae have been bred from beetles. 



The species listed below were determined by Dr. Aldrich. 

 In addition to these there are five undetermined species. 



687. Myiocera cremides (Walk.) 

 Vale, VI 11-15. 



688. Thelaira leucozona (Panz.) 

 Hood River, VI (Cole). 



689. Melanodexia tristis Will. 



Corvallis. 



690. Trixia gillettei Towns. 

 Mosier, VI-14 (Cole). This species has been considered 

 a tachinid in the past and really does not belong in Trixia 

 which is a tachinid genus; neither does it belong in Para- 

 phyto where it was placed in Aldrich's Catalogue. It does 

 not fit any of the dexiid genera in North America.
