PROCEEDINGS, I!)20 - 33 



M.i^uient, a row of raised brown tubercles on stiti'iiia, that on tlie second 

 abdominal segment partially overlapping the upper edge of the wing 

 cover, on the third the tubercle is just above the edge of the wing cover, 

 on the fourth there is a secondary tubercle below and anterior to the 

 major one, the anal segment is without tubercles and is armed with 

 :'\eral short spines. 



The pupa was enclosed in a white silk cocoon placed mostl}- within 

 the tttnnels. This factor was mainly responsible for the almost com- 

 plete loss of the resulting imagoes, some of them being denuded of all 

 scales in their passage through the silk net, whilst others were damaged 

 by contact with the honey, the net result being one male and one female 

 secured for identification. 



Date of emergence. May 29th, 1919, on which date two specimens 

 \\ere taken at light outside. The latter agree with some named V. serra- 

 tilineella by Dr. Dyar, the bred specimens are slightly grayer and are 

 not so contrasting in maciilation. I am indebted to the kindness of Dr. 

 J. McDonnotigh for verification of my indentification. To quote from 

 his letter, he says; "I think you will 1)e safe in calling the species 

 V. serratilineella, although personally I have never been satisfactorily 

 able to separate this western species from its near ally in the east, 

 V. edmandsi Pack. The maculation is identical and the haljits appear 

 to be the same in both species, the only difference being that the western 

 form is slightly larger. However, in view of the geograp^iical distribu- 

 tion it seems advisable at present to retain the name serratilineella for 

 the western form." 



The habit referred to by Dr. McDonnough, is the fact that V. 

 edmandsi is- an incjuiline of Bumble Bees nests in \\-hich it feeds; a 

 description of this is given in. Parkard's Guide to the Study of Insects. 



Dr. Dyar in Pro. U. S. Nat. Museum, Vol. 27, page 921, records 

 having taken this moth at Shawnigan Lake, B. C, Aug. 17th and Sept. 

 4th, whilst the Kaslo specimen that he had for identification was dated 

 June 24. The dates of those in my collection are May 19, 29, June 7, 

 24, 29, July 9, 19, -Aug. 12, Dec. 30, the latter taken in the house this 

 \\inter. 



I have also received specimens from Mr. Williams llugli, of Clover- 

 dale, B. C. His opinion is that it can never be considered an injurious 

 pest, "strong colonies never tolerate its presence and the bees certainly 

 clean up the webs from the combs." 



Mr. F. W. L. Sladen, Dominion .\i)iculturist. writes mc that he has 

 never observed it, and Mr. W. J. Sheppard. Provincial Apiculturist, also 

 informs me that although he examined thousands of hives in British 

 Columliia during the past six -years that he has not seen anv evidence 

 of it. 



The conclusion is. that this moth will onl_\- be found amongst stored 

 frames or diseased colonies.
