THE CANADIAN ENTOMOLOGIST. 251 



400. A. flagellum, ^Valk — Redesciibed from here by Prof. Sniilh as 

 insolita, of which the type is at Washington. It is figured in Ent. News, 

 VI, PI. XV. Noi common, but regular in appearance. Middle July and 

 Aug. 



401. A. rnbidus^ Ottol. — Four 9 ? o'lly- Two are in my collection. 

 One is dated July 2nd, 1901, and was the first I ever saw. It has been 

 seen by Dr. Ottolengui, and is a good specimen. The other, dated June 

 26th, 1903, is badly rubbed. A ? from here is in the U. S. National 

 Museum, and another is in the British Museum. At finst sight it might be 

 taken for an aberrant pccationis or pseudogamiiia, but amongst other 

 differences it is easily distinct from both by the sign, which runs to a 

 rather sharp point posteriorly. It was described from Cartwright, Man., 

 and St. John, N. B., and a good figure is given with the description. The 

 type is a 9 in Dr. Ottolengui's collection. 



402. A. alias, Ottol. — I have a ^ from Blackfalds, Alia., about a 

 hundred miles north of Calgary, taken by Mr. Gregson on July 28111,1902, 

 which bears Dr. Ottolengui's label, and has been seen by Sir George 

 Hampson. The species is stated by its author to be common throughout 

 Canada and the Northern States, and to have been confused with 

 u-aureiim, whilst resembling rectatigula. U-aureiim is now dropped from 

 our lists as not North American. The type is a c? i'l Dr. Ottolengui's 

 collection. I have two Pine Creek specimens dated Aug. 9th and i6th, 

 which I should say are undoubtedly the same species, and a fourth from 

 St. John, N. B , which was sent me a few years ago as mortuorum. All 

 agree with the two figures oi alias given in Dr. Ottolengui's payjer. One 

 Didsbury (Alta.) and two Pine Creek specimens show some slight modifi- 

 cations' in the sign, but after much study I have not been able to satisfy 

 myself that they differ specifically. I sent one of these to Sir George as 

 possibly excelsa, and he returned it labelled octoscripta. It is certainly 

 not unlike Dr. Ottolengui's figure of that species, which, however, is not 

 clear in detail. It bears date Aug. 21st, 1903, and the others are dated 

 Aug. 7th and 9th, 1903-4. 



403. A. excelsa, Ottol. — I have the name only, but Dr. Ottolengui 

 tells me that he has at least three specimens from me. One of these is a 



(^ , taken at light on Aug. 29th, 1895, and was named angulidens for me 

 by Prof. Smith some years ago. The two species are stated to be very 

 much alike, but separable amongst other differences by the sign, which in 

 the present species is rather V-shaped, and in angulidens more like a U. 

 It has the same range as a/ias, whereas angulidens appears to be
