ART. 2 A REVISION OF THE GENUS PROCEOIDOCHARES ALDRICH 9 



In 1873 Loew erroneously said that the Winthem material was from 

 Mexico; the Mexican specimen there mentioned was not included in 

 the original publication, hence is not a type. 



See minuta for Felt's specimens reared from ChrysotJiamnus in 

 Utah. 



PROCECIDOCHARES ATRA, variety AUSTRALIS, new variety 



Differs from the typical form by the characters mentioned in the 

 key. The second and third wing bands are slightly connected at the 

 third vein. 



Described from three specimens. The type, a female, was reared 

 at Waco, Tex., by W. Dwight Pierce, from head of Heterotheca suh- 

 axillaris; it emerged October 3, 1906. One male was collected at 

 Llano, Tex., on October 23, 1905, by A. W. Morrill; the other was 

 taken by sweeping at Orlando, Fla., on February 28, 1918, by G. G. 

 Ainslie (Aldrich collection). 



Type— Female, Cat. No. 41762 U.S.N.M. 



PROCECIDOCHARES PLEURALIS, new species 



Female. — Head yellow, the occiput black down to the neck and 

 narrowly below; eye small and narrow, the cheek equal to almost one- 

 third its height (0.32) ; front at vertex 0.51 of head width. Parafacial 

 wider than usual, nearly as wide as third antennal joint; cheek with 

 a few black hairs extending almost up to the eye, and behind these 

 rather bushy pale ones. Thorax, abdomen, coxae, and basal two-thirds 

 of femora black; middle half of mesonotum pollinose except for two 

 narrow shining stripes in front, and with irregularly placed flattened 

 pale hairs, which are numerous and leave only two narrow submedian 

 bare stripes; the anterior lateral polished area is smaller than usual; 

 scutellum polished, the postscutellum opaque above, but highly pol- 

 ished on lower half except laterally ; metanotum white pollinose except 

 close to junction of abdomen. Knob of halteres brown to blackish. 

 Pleurae pollinose when viewed from in front except middle and hind 

 part of sternopleura, when viewed from behind more shining on 

 posterior half; no black bristles, only bristly pale hairs, on pleura. 

 Abdomen opaque, shining only on last segment before ovipositor, the 

 latter shining black and very long, usually longer than preceding 

 part of abdomen without including the telescopic portion. Hairs of 

 abdomen wholly whitish. Femora broadly yellow on apices. Wing 

 as in Plate 18, Figure 30, of Mrs. Phillips's paper (her setigera). 



Male. — Front at vertex 0.50 of head width; all details as in female, 

 abdomen with only pale hairs. 



Length, male 4 mm., female with ovipositor 5 mm. 



Described from 16 specimens of both sexes, reared "from gall on 

 sunflower stem," by H. K. Morrison, at Fort Huachuca, Ariz. 

 Emerged June 9 to July 18, 1883.
