44 B.C. Entomological Society. 



lieeu a great pleasure to me to help forward the subject of eutomology in the Prov- 

 ince, and iucideutall.v to meet so many men interested in the realm of insects 

 injurious or otherwise. 



On completing m.v .vear of office as President. I wish to thank you most cordially 

 for your attendance and support and for all the time you have devoted to the study 

 of entomology. 



May I be permitted to e.xpress the hope that your interest will not he allowed 

 to wane, and that our Society may continue to show its vitality by giving evidence 

 of good work accomplished, and may further justify its existence by fostering a 

 feeling of mutual help, encouragement, and incentive among the members, and that 

 as individuals we may each derive benefit from our association and co-operation as 

 a body. 



Before I sit down, there is another matter I wish to mention, and that is the 

 aid and recognition the Society has received and is receiving from the Government 

 through the Department of Agriculture, of which the Honourable Mr. Ellison is the 

 liead. I, for one, fully realize the importance and value of the support given, and 

 I think it is our bounden duty to pass a formal resolution at this meeting, which 

 can be done in its proper place later in the session, expressing our thanks and 

 ai>i:)reciatiou of the assistance rendered by grant of money and by the printing of 

 our Report, and, not least, of the encouragement and personal interest in the Society 

 liy the Honourable Mr. Ellison himself. 



NOTES ON SOME OF THE VARIABLE SPECIES OF THE GENUS HYDRIO- 

 MENA AND ITS ALLIES OCCURRING ON VANCOUVER ISLAND. 



By E. H. Blackmoue. Victoria. 



As I have been giving special attention to the genus Hj/drimncna and its allies 

 during the past season, and in addition have had my material determined by a 

 well-known si)ecialist, I thought that a short note on a few species and varieties of 

 this group would be of some use to the science of entomology in the Province. This 

 winter while cla.ssifyiug and rearranging the species belonging to the H yd riomena, 

 < oUected during the past season, I was struck by the remarkable variations occurring 

 in some of the species, and in some instances the constaue.v of the variations was 

 jiarticularly noticeable. As many of these forms were new to me, I compared them 

 Mith several local collections, and was surprised to find them listed under one or the 

 other of two names. However. I was convinced that the.v were different species, or 

 at least good varieties. I sejiarated them into as many series as their variations 

 would allow and sulimitted the whole to L. W. Swett, of Boston, Mass. He has been 

 to a great deal of trouble to get some of them determined, necessitating several trips 

 for comparison with large collections in the New York and Cambridge Museums, and 

 I am greatly indebted to him for his deteruiinatimis and also for a great deal of 

 information given me in his replies. 



The first species 1 wish to take up is the one listed as Mc.sulcucti U-unciita. 

 Ilnfnagel. in Dyar's List No. 3379. In the catalogue of British Columbia Lepidoiitera 

 issued in 1904 it is listed under that name, with the words " ver.v variable " after 

 it, .nid in th.e Check IJst of British Columbia Ijcpidoptera, published two years later. 

 MisoIcKca immanata is listed in addition to tntiicata, which is No. 3380 in D.var"s 

 List. Now. M. Iniiicata and M. iiitinanata were very badly mixed up until Mr. L. B. 

 Prout, of England, worked them out, giving the synonym.v and varieties in the 

 • Transactions of the City of London Entomological Society " in 1908. He showed 

 tliat triuicata is strictly European, and though closely allied to our form here is not 

 the same. The form we get in North America is cUrata, Linn., and described by 

 bini in 1701 from a specimen taken in Scandinavia, and is quite different from 

 Uuncata. The chief difference lies in the extra dislcal band beneath the hind-wing: 

 in tnincnta it is rounded all the wa.v, whereas in citrata it ends in a sharp angle as 

 it reaches the base. On the primaries above, the projections in tniiiciita are more
