the same genus under " Genera not described so as to admit of approxi- 

 mate location." I will not pursue the action further, but will simply ask, 

 is this serious entomology? And when Kirkaldy remarks anent 

 ChimarrJiometra that my " descriptions and figures are quite untrust- 

 worthy " (Can. Ent., XL, p. 453): I will ask, in reply, whether, on the 

 above statement of fact, Mr. Kirkaldy is to be accepted as a trustworthy 

 controversialist ? 



DESCRIPTION OF PSILOCORSIS FLETCHERELLA, A NEW 

 SPECIES OK MOTH OF THE FAMILY (ECOPHORID,^.* 



BY ARTHUR GIBSON, CENTRAL I \ PKRIMENTAL FARM, OTTAWA. 



In the Canadian Entomologist, March, 190S, the writer published, 

 under the name of Cryptolecliia quercicella, Clemens, a note on some 

 larva 1 , which had been found feeding on Populus tremu/oides, in the 

 Arboretum of the Central Experimental Farm, Ottawa. On further study 

 the moth reared from these larvae proves to be an undescribed species of 

 the genus Psi/ocorsis, as mentioned by Mr. August Husck in the Proceed- 

 ings of the United States National Museum, Vol. XXXV, p. 197, 1908. 

 As a tribute to the memory of my late chief and ever kind friend, from 

 whom I was always receiving the greatest encouragement and help in my 

 studies, I esteem it an honour to name it 



Psilocorsis Fletcherella, n. sp. — Alar expanse, 19 mm.

 dinal black lines, second joint thickened with appressed scales ; antennoe
