266 THE CANADIAN ENTOMOLOGIST. 



CoSSID^. 



562. Cossus Ce?itereusis, Lint. — A rather worn male at light, July 

 1 8th, 1902. The specimen was so named by Dr. Barnes, and is not 

 unlike Dr. Holland's figure of that species. Dr. Fletcher has seen it, and 

 doubts the correctness of the name, saying : " It looks too clean." 



563. C.populi, Walk. ? — Probably not rare. A large number of 

 balsam-poplar trunks ( F. bahamifei'a) are burrowed with what I believe 

 to be this species. I have bred a few from larvae taken from split wood, 

 or rather left in blocks of sawn or split wood. If removed from their 

 burrows the mortality amongst them will probably be high. Dr. 

 Ottolengui has the species from me, but could not name it with certainty, 

 and I have a specimen referred doubtfully \.o populi by Dr. Dyar. Two 

 males and a female are all I have now in the collection, and they show 

 considerable variation. Two males only have been taken at light, which 

 has nut b.en worked near their breeding ground, and besides these I have 

 never met wiih any except by breeding. July and early Aug. 



564. Piionoxystiis rohinice^ Pack. — One female in a freshly-built 

 Cottonwood ( Populus deltoidea) log building on Red Deer River, on 

 June 2ist, 1901. 



Sesiid.'E. ■• 



565. Bembecia marginata^ Harr. — A pair at rest on a Cottonwood 

 trunk on Red Deer Iviver on July loth, 1904. Dr. Dyar has seen the 

 male. 



566. Albuna pyramidalis, Walk. — One specimen near Billings's 

 mill, July loth, 1898. 



Hepialid/e. 



567. Sthenopis arge?iteomacu/atus, Harr. — I have a male in the 

 collection taken near the head of Pine Creek in 1894, which has been 

 so named by Dr. Dyar. Mr. Hudson took others, but says he never saw 

 it anywhere but in one valley. I do not think that Alder, in the roots and 

 stems of which the larva is said to feed, grows within four miles. It has 

 not been met with in the same district for nine or ten years, but the 

 locality has not been visited specially for it. Mr. C. Garrett seems to have 

 found it not uncommon on Fallen Timber Creek, 20 miles west of Dids- 

 bury, in 1904, and I am indebted to him for two males and a female. 

 One male is in colour exactly like Dr. Holland's figure of the species. 

 All other specimens I ever saw, including the Pine Creek specimen named 

 by Dr. Dyar, are smoky brown, with very little or nothing of an ochreous
