A NEW LEPIDOPTEROUS GALL-PRODUCER. 



BY A. COSENS, M.A., TORONTO. 



Stagmatopliora cea?iothieiiu, n. sp. — This small moth produces galls 

 on Ceanoi/iJiS A?nericafius, L.; these abnormal growths are found com- 

 monly on a main stem, but rarely on a branch. The flower cluster is 

 sometimes entirely aborted, bu-t usually only partly so, the lower pedicels 

 in the cluster remaining normal. 



In the majority of cases the gall is terminal, but in a few instances 

 the stem was found to project a short distance beyond it. The gall has 

 the relatively simple structure of a spindle-shaped enlargement of ihe stem. 

 In length it varies from 10 to 15 mm., and in greatest width from 5 to 8 

 mm. It is roughened on the outside by the stumps of the aborted 

 branches. On account of the shortening of the stem axis and the conse- 

 quent crowding of the nodes, these branches are more numerous on a gall 

 than on a corresponding length of normal stem. This gives the gall a 

 gnarled surface and forms a strongly-protected case for the larva. The 

 gall in some cases is surmounted by a tuft of leaves growing from its apex. 



The aperture through which the moth escapes from the gall is made 

 always near the upper end.
