THE CANADIAN ENTOMOLOGIST 191 



Colorado is in the Henry Edwards collection, and is a reddish 

 califoniica. That oifratella, as well as oil, is in the British Museum, 

 and I was satisfied that they were one species. Fratella is under- 

 sized. The type of on had either no hind legs or they were so 

 tucked up in the vestiture that I had no chance of finding 

 spines. 



401. A. rubidium Ottol. — I have six more local captures of this 

 species in my collection, dated June 1st to July 5th, 1909 and 1910. 

 It comes to light and treacle, and I have taken it on the wing after 

 dark flying over vetches. I took six specimens during 1909 alone, 

 five of them at treacle. The tail of the sign is not always produced 

 to a point as in Ottolengui's figure of the type. It sometimes 

 widens out into a slight lobe, rather like that of caUfornica. On 

 the other hand, I have caUfornica in which the tail is much like 

 that of the type of rubidus. The nearest well-known relation to 

 rubidiis is precationis. 



402. A. alias Ottol. — I have only four Alberta specimens in 

 my collection which I feel quite certain are this species. The 

 Waghorn (Blackfalds) specimen previously referred to, a 9 with cf 

 abdomen attached, July 25th, 1902. A cf and two 9 s, Head of 

 Pine Creek, Aug. 7th, 9th and 16th, 1897 and 1903. They agree 

 with Ottolengui's figures, and have the sign nearer to that of 

 rectangida than any other species, but not as heavy. In fact, alias 

 is the nearest ally that rectangida has. Also taken at Banff, Aug. 

 4th, 1908 (Sanson). 



I long hesitated in separating from this a form which I have 

 been calling octoscripta. I have a local female, dated Aug. 21st, 

 1993. and another from Mr. Wallis, Winnipeg Beach, Man., Aug. 

 23rd, 1910. The latter specimen is almost the exact counterpart 

 of Ottolengui's figures. Mr. WalHs showed me another female 

 taken at the same place, Aug. 22nd. I have also given this name 

 to a Banff male, one of Mr. Sanson's captures, August 1910. This 

 has a niDre spider-like sign than any of the others. I have a male 

 from Cowichan Bay, near Duncans, Vancouver Island, which is 

 brighter coloured and has heavier sign, but which I think is the same. 

 It resembles alias very closely in colour and general pattern, but is
