sions, one on each side, over the bases of the anterior wings, scutel 

 finely wrinkled and with deep smooth foveas, pleurae finely striate ; 

 wings dusky, veins distinct, areolet sometimes obsolete, radial 

 area open, radial vein reaching to the first transverse vein, second 

 transverse vein spreading out at the base of the radial area into 

 a dark reddish brown cloud; legs dark amber color, except the 

 trochanters and the middle of the femora and tibiae, all of which 

 are clear dark brown ; abdomen black and smooth, but with the 

 ventral sheath reddish brown. What is believed to be the male 

 of this species has the legs darker, the antennae 14-jointed and 

 the third joint deeply incised. 



The gall is 25 mm. long, 18 mm. thick, and occurs as an 

 abrupt swelling involving the whole circumference of the stalk 

 of Rubus strigosus. The gall is pecked by birds and the legiti- 

 mate inmates of the gall are attacked by many parasites. 



Rhodites Hartig. 



R. bicolor Harris. Spiny Rose Gall. 



Thorax opaque, furrows between the parapsidal grooves 

 appearing as distinct ridges when viewed obliquely, scutel deeply 

 rugose, pleura with hardly any representation of a glossy spot 

 but almost uniformly sculptured throughout; second transverse 

 vein with a light projection at about its middle in the radial area, 

 the veins forming the anterior angle of the areolet and the part 

 of the cubital vein before the areolet often subobsolete, close by 

 the posterior angle of the areolet a pale brown line like a stump 

 of a vein. Female : length nearly or exactly 4 mm. ; with a brown- 

 ish cloud on the radial area of the wings ; legs, except at bases of 

 coxae reddish ; abdomen reddish. Male : almost exactly as long 

 as the female, mostly black' legs reddish, except coxae, which 

 are black; wings rather clouded along the distinct veins and 

 with two conspicuous clouds in the apical area. 



The galls of this species occur singly or in clusters of three 

 or four, the galls themselves are 9 to 10 mm. in diameter and 

 covered with spine-like processes nearly as long as the diameter 

 of the gall itself. It is said to be the commonest rose gall.
