cannot feel sure that the differences are specific, the macula- 

 tion being admittedly similar. I have seen no Calgary speci- 

 mens quite as bright as Prof. Smith's liquida nor have I any 

 such from other localities. Lilacina, an allied species, has an 

 even greater range of variation, and at Calgary I take the even 

 dull gray form called illabefacta by Morrison, and every inter- 

 grade up to a form as bright and contrasting as supposed typ- 

 ical liquida. 



Luperina extensa Sm. 



Smith now refers his Perigca flavistriga to this species. The 

 latter was described from Lethbridge, Alta, and extensa, prior 

 by half a page only, from Regina, Sask. Flavistriga was pro- 

 cured through me, extensa through Dr. Fletcher, and both, 

 oddly enough, were taken by Mr. T. N. Willing. When at the 

 British Museum I made the reference in my notes, with a 

 query, from figures of each type sent there by Prof. Smith. 

 The venture was risky, but proved correct. The type of ex- 

 tensa, which is now greasy and probably much discolored, is 

 poorly marked and almost the color of a dark passer. Flavi- 

 striga is well marked, and blacker brown. I have a splendid 

 specimen from the Red Deer River compared with both types. 



Hyppa spaldingi Sm.. (Jour. N. Y. Ent. Soc. xvii, p. 59, June, 1909). 

 Described from Stockton, Utah. This is prior to Trachea 

 umbrifacta Hamps. (Cat. IX, 501, 1910), described from the 

 same locality. The type of umbrifacta is a female, one of sev- 

 eral specimens received by me from Mr. Thomas Spalding, 

 dated May 30 to June 27, 1907. I took a couple to the British 

 Museum, but not finding it in the collection, left one for Sir 

 George Hampson to describe. Spaldingi was a unique, also a 

 female, and did not pass through my hands. Smith, while 

 describing it as a Hyppa, remarked that it was quite unlike our 

 other Hyp pas, and recalled the yellow-winged Xylophasia seini- 

 htnata and inordinata. It is more like cinefacta, and has the 

 thoracic vestiture and the tuf tings of that species. Hampson 

 places both, with others of our Hadenas, in Trachea Ochs.
