Artemisia, as do also G. artemisice, Bouch., G. tubifex, Bouch., 

 and C. foliorum, Scholtz. 



Inquilines and Parasites. 



The following have been bred from galls, collected at West 

 Cliff, Colorado, of the species considered above : — 



(1.) Nematus concolor, Nort. Bred May 15th, from gall of C. 



rigidce. 

 (2.) Pteromalid, long 2f mill. Bronzy green. Bred, May, 



1889, from gall of C. s-brassicoides. 

 (3.) Pteromalid, long, about 2|- mill. Bronzy ; legs partly dark 



brown and partly honey-yellow. Bred, May, from gall 



of C. s-brassicoides. 

 (4.) Eutelus sp., about 1^ mill. long. Yellowish green ; legs 



pale yellow ; venation yellow. Bred, May, from gall of 



C. s-brassicoides. 

 (5.) Eutelus sp., similar to the last, but much smaller ; abdomen 



more tapering. Bred, May, from gall of G. s-brassicoides. 

 (6.) Pteromalid, rather smaller than No. 4. Black. Bred, May, 



from gall of C. s-brassicoides. 

 (7.) Chalcid. Metallic greenish; legs pale brownish ; antennae 



pale at tips. Bred, May, from gall of C. s-brassicoides. 

 (8.) Chalcid. Black or nearly so ; head greenish ; shape of 



abdomen rather like that of Isosoma. Bred, May, from 



gall of C. s-brassicoides. 

 (9.) Cecidomyia, much like frater, but much smaller. Not 



sufficiently examined, but may be albovittata, Walsh. 



Bred, May, from gall of G. s-brassicoides. 

 (10.) Chalcid. Black; legs honey-yellow; thorax smooth ; fla- 



gellum pubescent. Bred, May, from gall of G>S:brassi- 



coides. 

 (11.) Polygnotus error, Fitch. Bred from gall of G. s-brassicoides. 

 (12.) Torymus sp. Bred from gall of C. rigidce. 

 (13.) Torymus sp. Bred from gall of G. s-brassicoides. 

 (14.) Tetrastichus sp. Bred from gall of C. s-batatas. 

 (15.) Torymus (n. sp. ?). Bred from gall of C. alticola. 



I am indebted to Mr. W. H. Ashmead and the U.S. Depart- 

 ment of Agriculture for assistance with the above Hymenoptera. 

 The Chalcids have not been sufficiently studied as yet ; probably 

 some of the species bred will ultimately prove undescribed.
