114 THE CANADIAN ENTOMOLOGIST, 



CANADIAN RHYNCOPHORA. 



Since writing the notes on Rhyncophora which appeared in the 

 February issue, I have had an opportunity of obtaining Dr. Sharp's deter- 

 mination of the two species mentioned on pages 22 and 23. He writes 

 tome as follows : — "The two weevils from Cape Breton are: i. Otio- 

 rhynchus ritgifrofis, Gyll., 2. Sciaphilus tnuricatus, both common N. 

 European insects. The Otiorhynchics is a slight var.; the Sciaphilus not 

 distinguishable from Scottish specimens." W. H. Harrington. 



ARCTIA ARIZONENSIS, STRETCH. 



I obtained eggs from a worn % taken at light near Salt Lake City, 

 Utah, in June ; these gave me a fine lot of imagines early in September, 

 and I again got eggs from them, and had larvae feeding which produced 

 a number of moths at various times during the winter. Some of the 

 larvae ceased to feed when one-third grown, and I dumped them out 

 among weeds by my orchard fence to take their chances. From the two 

 broods I got about 150 fine examples of the perfect insect. Part of the 

 first lot were fed up by a friend in Ogden, Utah, and sent to me as 

 pupse, part were fed in Denver City, and many I reared in the mountains 

 above Platte Canon (10,000 feet elevation). The last brood were reared 

 in Western New York. The larvae were very easy to manage and ate 

 freely of almost anything. Plum, willow, plantain, polygonum, lettuce 

 and chickweed were given them as best and easiest obtainable, but 

 nothing seemed to come amiss. Under the different conditions of altitude, 

 climate and food I ought to have obtained varieties, if the species varies 

 at all, but I never bred any Arctia?is that kept so constant to the parent 

 form. I also have about a dozen of both sexes taken at light in Utah 

 and Central Colorado, and these also are the counterparts of my bred 

 examples. All the males are precisely like Stretch's figure of Arizonensis 

 (?, the % % exactly like his Autholea $, in the same work (Zyg. and 

 Bomb.), but not one male was like his Autholea ^ as there figured, but 

 all well spotted on underwings like his figure of Arizonensis ^ . I give 

 description of the mature larva (the earlier stages were plain black) : — Head 

 and thoracic feet shining black with tinges of chestnut ; body velvety 

 black with narrow reddish brown dorsal line (produced by two linear 

 spots on each segment), all tubercles intensely black, those above lateral 

 fold all crowned with bunches of short black hairs ; those on second and
