Anthonomus nigrinus Boh. Buds of Solanuvi carolinense 

 containing immature stages of this species were collected by 

 F. C. Chittenden at Washington, D. C., for the purpose of 

 breeding parasites. The larvae work differently from those of 

 the preceding species in that they make their cell in the centre 

 of the narrow bud, through the pistil and anthers, thus pre- 

 venting the opening of the flower, and causing an early drop- 

 ping of the infested buds. An examination of material col- 

 lected about July 3rd yielded one hundred and eleven weevil 

 stages, of which 18 or 16.2,^ were parasitized. 



PARASITES. 



Catolaccus incertus Ashm. Quite a number of specimens of 

 this species were bred. 



Anthonomus squamosus Lee. This weevil was found by the 

 writer breeding in the flower heads of Grindelia inuloidcs at 

 Dallas, Texas, August 4, 1906, and was identified from its 

 pupa. A larva presumably of this species was found in a 

 flower head of Grindelia grandiflora Hook. (det. by C. F. 

 Wheeler), collected at Paris, Texas, September 2, 1905, by F. 

 C. Bishopp. 



ASSOCIATES. 



Rhagoletis grindeliae Coq. Two specimens of this new fiy 

 were bred June 2, 1906, from cells in the heads of Grindelia 

 squarrosa nuda collected at Clarendon, Texas, September 19, 

 1905. The external indication of the presence of this insect 

 is identical to that of Anthonomus squamosus. The larva 

 makes a little cell among the seed. It is white, with both 

 apices flat and black. 



Agromyza jucunda Walk. (det. by Mr. Coquillett). One 

 specimen of this fly was bred from the flower heads. 



Urellia maverna Walk. (det. by Mr. Coquillett). Several 

 specimens of this beautiful fly were bred. The robust white 

 larvae, with head and apex of abdomen flattened and black, 

 appear like little barrels. They occupy cells very similar to 

 those made by Anthonomus squamosus, and their presence is 

 indicated in the same manner. The pupae are brown. These 

 flies were bred during September, 1905. The biology is short.
