18 B.C. EXTOMOLOGICAL SOCIETY 



at our last annual meeting. A more complete revision of this group 

 has just been given by Mr. Swett in the Can. Ent., Vol. XLIX., page 64 

 et seq. (February, 1917), wherein he has described the three following 

 new aberrations : 



Dysstroma mulleolata ab sobria Swett. This is a form which has 

 the median band solid black and is the rarest form of all. So far I have 

 only taken one specimen and that is the type which is in the collection 

 of Mr. Swett. 



D. mulleolata ab subumbrata Swett. In this form, which is a transi- 

 tion stage between the black-banded and the white-banded forms, the 

 black central band has begun to break up into greyish spots and shad- 

 ings, especially at the costal and inner margins. Of this form I took 

 four specimens in 1914 and two in 1915, but have not seen it since. 



D. mulleolata ab ochrofuscaria Swett. Of this form I have only 

 taken one, and that is the type taken on the 27th June, 1915. Mr. G. O. 

 Day took a female at Quamichan Lake in 1908, which has been made a 

 paratype, as also is a male taken by Mr. A. W. Hanham in the same 

 district in 1910. I believe Mr. Hanham has also one or two more of 

 them. 



I am not quite so sure of this latter being a variety of mulleolata. 

 The course of the extra-discal line is different, and there are one or two 

 other minor points which make me think that it may be a distinct species 

 when its life history is worked out together with a study of the genitalia. 



This concludes the list of species and varieties new to science which 

 have been described from British Columbia during the past twelve 

 months. Turning to those geometers which I have discovered during 

 the past year as being new to British Columbia, the first to claim our 

 attention is Hydriomenia furcata var. periclata Swett. I found this 

 interesting geometer resting on the outside of my house on April 4th, 

 1916. It was described from a single male taken at San Francisco in 

 1909, and seems to be of very rare occurrence. 



Stamnodes topazata var. albida B. & McD. where the deep 

 ocherous colour of topazata gives place to a creamy white. This speci- 

 men was taken by our energetic librarian, Mr. Williams Hugh, and is 

 rather illustrative of what is generally known as fisherman's luck. Mr. 

 Hugh was over in Abbotsford for a few days in the early part of April 

 last year, and one day seeing a few geometers flying about, he caught 

 half a dozen with his hat, and brought them back with him in a 

 matchbox. 



Five of them were the common M. gratulata, and the other a new 

 addition to the list. I am only sorry that the numbers were not reversed. 

 Our thanks are due to Mr. Hugh for putting a new record on our lists 

 in such a lucky manner. 



Sciagraphia orillata Walk., taken by Mr. Anderson at Penticton on 

 May, 1913. This was placed as a synonym of continuata Wlk. liy Dr.
