Dec, I9IS-] Townsend: New Muscoidea. 231 



(Cockerell) ; one female, Las Vegas Hot Springs, New Mexico, August 9 (H. 

 S. Barber). 



Differs from color description of Chrysocxorista viridis only as follows: 

 Second antennal joint obscurely rufous, wings with a very faint fuscous tinge. 

 The inner thoracic vittae are rather more linear. A median fifth vitta nearly 

 as dark as the others, but, unlike the others, fading with incidence of light, 

 as is the case in Chrysocx. viridis. A label by Cockerell on the male reads : 

 " In life brilliant golden shot with green." 



Holotype, No. 19613 U. S. N. M., male. Allotype, female. 



Exorista ochracea Wulp probably belongs to this genus. It is de- 

 scribed as having only four thoracic vittae, the inner pair not extended 

 behind the suture, the antennae wholly black, eyes thinly pilose, and 

 is very much smaller, 



PHCENICIOMYIA new genus. 



Genotype, Phocniciomyia arisonica Townsend new species. 



Differs from Tachinophyto as follows : Male. — Cheeks and para- 

 facials narrower, front about one third head width. Second antennal 

 joint hardly so elongate, the third joint two and one half or nearly 

 three times second. Two or three sternopleurals, three postsuturals ; 

 three strong lateral scutellars, apical decussate pair not erect. All 

 segments with median marginal, last three with median discal, last 

 two with marginal row, all erect. Apical cell closed in border, end- 

 ing far before wing-tip; cubitus angular, half way between front and 

 hind margin of wing; apical crossvein well bowed in, subparallel with 

 hind margin of wing; hind crossvein nearly half way between cu- 

 bitus and small crossvein, sinuate, subparallel with apical crossvein ; 

 last section of fifth vein more than half as long as preceding section, 

 but not nearly as long as same. Costal spine distinct, third vein 

 bristled nearly to small crossvein. Hypopygium larger. Claws a 

 little longer. 



Phceniciomyia arizonica new species. 



Length of body, 6.5 mm. ; of wing, 4.75 mm. One male, Phoenix, Arizona, 

 March 31 (Cockerell).

 palpi light rufous; antenna; blackish, first two joints brownish. Thorax and 

 scutellum silvery ; four thoracic vittae, the inner pair linear. Abdomen polished 

 black, the bases of segments two and three rather broadly densely silvery-white
