ART. 2 A REVISION OF THE GENUS PROCECIDOCHARES ALDEICH 5 



and slightly again before the second vein; while the subhyaline area 

 between the second and third bands widens rapidly from the third 

 vein to the hind margin. 



Length, 3.2 mm. 



The specimen is in the University of Kansas collection. 



PROCECIDOCHARES FLAVIPES, new species 



Female. — Front at vertex 0.43 of head width, narrowing to anten- 

 nae, where it is 0.34. Cheek one-seventh of eye height. These 

 measurements indicate a much larger eye than in most of the 

 species. Head yellow in ground color except the occipital region, 

 wholly yellow below ; palpi and antennae yellow ; three pairs lower 

 frontals; the usual pale bristles behind the eye and one black next 

 the mouth at the side. 



Thorax black, the scutellum and the two pairs of mesonotal bare 

 fspots highly polished ; median region of thorax opaque and bearing 

 the usual pale flattened hairs, it is strongly narrowed posteriorly, 

 at the prescutellars being narrower than the space between them, 

 then suddenly widening to border the base of the scutellum, where 

 the flattened hairs are crowded and conspicuous. No presutural dor- 

 <30central bristle. Anterior acrostichal pale hairs in a single row 

 nearly to the suture. Pleurae wholly pale pollinose except a small, 

 distinct black spot on the mesopleura in front of the wing and below 

 the posterior notopleural bristle. Postscutellum opaque black, meta- 

 notum pale pollinose elsewhere. Halteres yellow. Abdomen black, 

 shining on third to fifth segments, which are bare on apical half; 

 hairs of abdomen pale. Ovipositor rather short, not equaling the 

 three preceding segments. Wing with usual pattern which is not very 

 dark, especially in the middle of the bands; apical band widely sep- 

 arated from the second, not quite touching the costa except behind 

 the third vein; hyaline interval between first and second bands not 

 at all widened toward hind margin of wing. Legs yellow. 



Length, 3.2 mm., with ovipositor. 



Described from one female, collected by H. H. Kiefer on Socorro 

 Island, Gulf of California, May 9, 1925. Altitude, 2,000 feet. In the 

 California Academy of Sciences.

 Procecidochares atra (part) Phillips, Journ. N. Y. Ent. Soc, vol. 31, 1923, 



p. 137. 



Doane described the species from two female specimens, one being 

 from Collins, Idaho, July 27, 1928, collected by himself, the other 

 from Battle Creek, Mich., collected by me in 1897. Mrs. Phillips 

 placed his species as a synonym of atra.
