the seeds to fall. Numerous seed capsules examined during the win- 

 ter were found to contain only the empty cocoons and pupal shells. 

 From this it appears that the adults hibernate. In the spring and 

 early summer, no trace of this species was found. Its habits prior 

 to the appearance of the seed capsules are therefore unknown to us. 

 It is quite probable that the first brood develops in the immature 

 flower buds. 



A species of Microhracon, which Mr. Cushman states requires 

 further study, was bred from the dry seed capsule. 



Other Species of Mompha Associated with Evening Primrose. 



Mompha brevivittella Clem. 



syn. ccnotherivorella Chambers, 

 syn. (rnotheraseininella Chambers. 



Chambers described this species in 1864 in the genus Wilsonia 

 (Proc. Ent. Soc. Phil., 11. '428. 1864). Smith (Ins. N. J.) lists it 

 from Lucaston, October 18 (Dke.), and states that the larva lives 

 in the seed capsules of evening primrose, also that the species is 

 probably generally distributed. According to Dyar's Catalogue it 

 occurs in the Atlantic States. 



In our work with primrose insects this species was bred from 

 seed capsules collected at Rutherford, Oradell, Tenafly and Spring- 

 field, N. J., the adults issuing during the last of August and first 

 part of September. 



Mompha murtfeldtella Chambers. 



syn. albocapitella Cham, 

 syn. grisscrella, Cham, 

 syn. obscurusella Cham, 

 syn. parvicristafella Cham. 



This was described by Chambers in 1875 (Cinn. Quar. Jn. Sci., 

 Vol. II, p. 237) from a specimen received from Professor Riley and 

 Miss Murtfeldt. In the Canadian Entomologist for 1879, Vol. XI, 

 p. 6, Chambers gives the following information about the habits of 

 this species: "Miss Murtfeldt favors me with the following notes 

 upon the larva of this species : Feeds upon the flowers of Oenotheras 

 both wild and cultivated and is especially destructive to O. viissouri- 

 ensis. Eggs laid singly on sticky surface of calyx and larvae as soon
