Mr. Tom Wilson : A little ov.er a year ago Mr. Swaine was out and 

 took stock of it, but it is not very generally distributed. It is local. 

 We seem to have most of it in Stanley Park. I do not think it is at 

 Agassiz, and at Sechelt it may very occasionally be seen.

FURTHER NOTES ON THE SPECIES OF THE GENUS HYDRIO- 

 MENA, OCCURRING ON VANCOUVER ISLAND, B.C. 



By E. H. Bl.xckmore, Victoria, B.C. 



C)wing to the exceptionally fine weather which prevailed in this 

 district during the past season, and which has been very favourable 

 to Geometers, I have collected a large number of specimens, some of 

 which are new to science and some new to the British Columbia List. 

 I have also had the privilege of stud_\-ing se\-eral private collections 

 which, combined with my own captures, has enabled me to make some 

 further additions to our list and to supplement the notes contained in 

 my article on page 44 of Bulletin 4 of our Proceedings. I will confine 

 inyself in this short paper to a few notes on the different species of the 

 genus Hydriomena. 



Some little time ago Mr. F. Wolley-Dod, of Midnapore, Alberta, 

 sent me a short series of Hydriomena furcata var. quinquefasciata, and 

 comparing them with A^ictoria specimens in my collections, I was rather 

 surprised to find how much they differed, both as to size and colouring. 

 The Calgary specimens are smaller, ranging from 30 to 32 mm. and 

 being a greyish-green colour, while the Victoria forms measure from 

 33 to 35 mm. and are in most cases of a warm brown colour, differing 

 in individual specimens in the depth of the colouring, but none approach- 

 ing the colour of the Calgary specimens. During the past summer Mr. 

 E. M. Anderson, of the Provincial Museum, Victoria, while on a collect- 

 ing trip around Atlin, B.C., secured, amongst other interesting things, a 

 series of this insect, and it is worthy of note how clearly they resemble 

 the Calgary forms, both in size and colour. As Mr. Anderson's specimens 

 have been compared with Packard's type in the University Museum of 

 Plarvard College and pronounced identical, it seems to me that our \^an- 

 couver Island specimens are a distinct geographical race. 



A new addition to the British Columbia List is Hydriomena furcata 

 var. viridata Pack., of which I have taken two specimens, one at light on 

 May 22nd, 1914, and the other resting on a pine-tree trunk on June i8th, 

 1914. According to Mr. L. W. Swett. this is an exceedingly rare variet3^ 

 and. I believe that previously it has not been found outside of California, 

 which is the type locality.
