Descriptions of the New Cynipidae. 



BY WILLIAM BEUTENMULLER. 

 Rkodites uodulosus sp. nov. 



Female. Head, black, opaque, finely and evenly rugoso-punctate, 

 with scattered whitish hairs. Antennae wholly black and pubescent. 

 Mandibles rufous, black at the tips. Thorax subopaque, with rather 

 large coarse punctures. Parapsidal grooves broad, not deep and 

 rugose. Median groove from the scutellum broad, not deep and ex- 

 tending forward to nearly the ends of the parallel lines. These are 

 almost smooth, somewhat shining and scarcely reach the middle of 

 the mesonolum. Lateral grooves very fine and scarcely evident. Pleurae 

 finely and densely rugoso-punctate with a large shining area. Scutel- 

 lum well rounded posteriorly, evenly rugose and without fovese at the 

 base. Abdomen, red; anal segments, black or blackish; ventral sheath, 

 jet black; first and second segments, smooth, remaining ones rather 

 densely covered with short decumbent hairs on the dor sum and sides. 

 Venter, smooth and without hairs. Legs, reddish and pubescent. 

 Wings, yellowish hyaline, radial area darker than the rest of the 

 wing. Veins dark brown, cross-veins heavy. Areolet present. Cubitus 

 distinct and extending to the first cross-vein. Length, 3 to 4 mm. 



Gall. On the two tender twigs of wild rose (Rosa lucida?} It is 

 an elongate, slight swelling of the branch and sometimes scarcely dis- 

 tinguishable from the rest of the branch. Inside is a Dingle, short, 

 elongate chamber inhabited by a single larva, which when fully grown 

 fills almost the entire chamber. Length, 8 to 12 mm.; width, 2 to 

 4 mm. 



Habitat: Magnolia, Massachusetts (Miss Cora II. 

 Clarke) ; Evanston, Illinois (Lewis H. Weld). 



A large and distinct species, allied to R. dichloccrus, but 

 with the color of R. rosac, ignota and bicolor. The galls 

 were kindly sent to me by Miss Cora H. Clarke and Mr. 

 Lewis H. Weld. They were collected in March and April. 

 The flies began to emerge about April 20 until early in May. 

 The gall is sometimes an imperceptible swelling of the 

 branch and may be easily overlooked. 



Andricus aciculatus sp. nov. 



I'cmalc. Head, rufous ; opaque, evenly granulated and with distinct 

 whitish hairs. Antenna; fifteen-jointed, rufous, darker terminally, 

 pubescent. Thorax rufous, black along the lateral grooves and be- 

 tween and around the anterior parallel lines, densely and finely rugoso- 

 punctate, with yellowish hairs. Parapsidal grooves, broad, distinct,
