(j 24 Provincial Museum Report. 1017 



Amongst the Geoinetridse the same collector took a specimen of Ifydriomena furcata var. 

 periclata Swett. This is the first record for British Columbia of this insect, its type locality 

 being San Francisco, Cal. ; also two specimens of Ania linib at a Haw., and one specimen of 

 Mctancma inatomaria Gue. These are the first captures of these two geometers that have been 

 recorded for over twelve years from this district. 



Geometrid.e sew to Science. 



Through the activities of Mr. E. H. Blackmore, who is still pursuing his studies of the 

 British Columbia Geornetrida>, two species and four varieties new to science have been discovered. 

 They have been described by Mr. L. W. Swett, the well-known geometrid specialist of West 

 Somerville, Mass., the descriptions appearing in the Canadian Entomologist. Vol. XLVIII., page 

 249 et seq. (July. 1916), and Vol. XLIX., page 64 et scq. (February, 1917), and are here 

 illustrated for the first time. (See Plate Till.) 



They are as follows: Momenta obsoleta Swett, described from three specimens taken at 

 Goldstream and Victoria, B.C., found in the collection of the late Captain B. V. Harvey, and 

 one specimen found in the Provincial Museum collection taken at Victoria, and all dated April. 

 190S. The latter was made a male paratype and is now in the exhibition collection of the 

 Museum; Hydriomena californata ab. niveifascia Swett, described from two specimens — one 

 taken at Goldstream and the other at Victoria — found in the collection of the late Captain 

 Harvey ; Diastictis andersoni Swett, described from three specimens taken by E. M. Anderson 

 on his trip to Atlin, B.C., in 1914. A male paratype of this. new species is also in the Museum 

 exhibition case; Dysstroma mulleolata ab. sotiria Swett, described from a single male taken 

 by E. H. Blackmore at Victoria in June, 1914; D. mulleolata ab. subumbrata, Swett, described 

 from five specimens taken by Mr. Blackmore at Victoria in June and July. 1914-15 ; and D. 

 mulleolata ab. ochrofuscaria Swett, described from specimens taken by Mr. E. H. Blackmore at 

 Victoria, B.C., and by Mr. G. O. Day and Mr. A. W. Hanham, at Duncan. B.C. " 



Mr. Blackmore has kindly donated to the Museum collection .a female paratype of D. 

 mulleolata var. subumbrata Swett. and a typical specimen of D. mulleolata var. ochrofuscaria 

 Swett. 



COERIGDNDA JND ADDENDA. 



Owing to a further examination of the types of North American butterflies by that eminent 

 lepidopterist Dr. J. MeDunnough, of Decatur. 111., two of the species figured in the Provincial 

 Museum Report for 1915 have been found to be named incorrectly. 



Partmssms smintheus var. nanus Xeu. (page 16 and Figs. 2 and 3, Plate VIII.) should be 

 corrected to Parnassius smintheus Db.-Hew. (vide Cont. Dep. No. Amer.. Barnes & MeDunnough. 

 Vol. III., No. 2, Dec, 1916). The specimens taken at Atlin in 1914 are identical with the type 

 specimens in the British Museum taken by Lord Derby in the Canadian Koekies. The aberration 

 nanus Neu. occurs in the male only, and is distinguished by having the two red occelli on the 

 secondaries replaced by one black spot. 



Brenthis frigga var. improba Butler (page 16 aud Figs. S and 9, Plate VIII.) turns out to 

 be Brenthis youngi Holland, described from Alaska in 1900. This is another new record for 

 British Columbia and was taken at Atlin in 1914. 



On page 17 (Eneis noma var. taygete Hub. should be changed to CE. taygete Hub., .as the 

 latter is a species quite distinct from noma Thun. 



Owing to an oversight on the part of those making the " cut " of Ehachogaster kcrmodci 

 Townsend (Plate X., Fig. 1) the name of the artist was omitted. The drawing was made by 

 Mr. C. W. Young, who is attached to the Experimental Farm at Agassiz. and is an excellent 

 piece of work.
