Male: Wholly pitchy black. Legs rufous. Anterior parallel 

 lines less distinct, and with traces of a median groove. Antennae 

 14-jointed, all pitchy black. Abdomen small and wholly black, 

 first, second and third segments smooth and shining, following 

 segments densely punctate. Wing without the yellowish cloud in 

 the radial area, veins very heavy. Length 2.25-3 mm. 



Gall: On the terminal parts of the branches of wild rose {Rosa 

 sp.). Green, polythalamous, round or irregularly rounded or 

 somewhat elongate, swelling, covered with numerous aborted 

 leaflets and filaments, giving it a mossy appearance, somewhat 

 like that of R. roscc with the mossy substance removed. Inside it 

 is a dense pithy substance with numerous larval cells. Diameter 

 20-35 T^T^- 



Habitat : Berkeley, Gal. (Dr. E. G. Van Dyke). Types : W. B. ; 

 paratypes : Mus. Gomp. Zool., Gambridge, Mass. ; Am. Ent. Soc, 

 U. S. Nat. Mus. and British Mus. 



The galls were found on a species of wild roses brought from 

 the San Jacinto Valley in Southern Galifornia and planted in a 

 garden, and the gall probably occurs on other species of wild 

 roses. It matures in November and the flies emerge in February 

 and March. 

 Rhodites pustulatoides sp. nov. 



Female: Head jet black, somewhat shining, rugose with shining 

 raised pustules on the lower part of the face and with short 

 whitish hairs. Antennae 15-jointed, first and second joints very 

 short, red; third joint very long, becoming stouter toward the 

 apex; fourth and fifth joints shorter than the third, equal in 

 length, and quite stout, remaining joints less stout and subequal, 

 all black with raised granules and very short hairs. Thorax jet 

 black, coarsely rugose with many shining pustules ; the parallel 

 lines, parapsidal and lateral grooves are all lost in the rugosity of 

 the surface and are but scarcely indicated. Pleurae coarsely 

 rugose and without a smooth central area. Scutellum very 

 coarsely rugose much more so than the thorax. Abdomen 

 smooth, shining and uniform red, anal segments punctate. Legs 

 yellowish-red. Wings yellowish hyaline, veins very stout; radial
