346 THE CANADIAN ENTOMOLOGIST. 



SuPERBA. — On May 26, 1903, six mature larvje of this species were 

 received from Mr. E. P, Venables, of Vernon, B. C. Tiie larva is a par- 

 ticularly striking one, and will doubtless prove to be one of the handsomest 

 of the genus. The following notes were taken on the six specimens : 



Length at rest 35 mm., extended 40 mm. Head 3 mm. wide, black, 

 slightly bilobed, subquadrate ; space above ocelli brownish, with dark 

 mottlings ; bases of antennfe pinkish ; hairs on face black, of varying 

 lengths. Body in general appearance blackish gray. Under a lens, how- 

 ever, the skin is seen to be streaked and blotched with white, particularly 

 laterally. Ventral surface of body paler, of a greenish-brown colour. The 

 white blotches are particularly intense between tubercles ii and iii. The 

 six larvae vary as to the intensity and numbers of the white blotches. In 

 two specimens the whole body is streaked and blotched with white ; and 

 the black skin appears as markings of that colour on a white body. 

 Dorsal stripe very distinct in all specimens ; in one almost pure white, in 

 the others pale yellow. In one of the specimens the dorsal stripe is 

 broken up into spots, three on each segment. Tubercles in all the larvae 

 black and shiny, i about one-fifth the size of ii, which has a polished base, 

 and is the largest; iii, iv, v and vi much the same size. Spiracles black, 

 with a pale, indistinct orange centre, close in front of tubercle iv. Bristles 

 faintly barbed, those from tubercles i, ii and iii being black and yellowish 

 intermingled, those from iv and lower tubercles being either yellowish or 

 rust- red. Thoracic feet black, prolegs reddish. 



One specimen spun a little silk on May 28, but did not change to 

 pupa until July 10. The cocoon is very simple, merely a slight covering, 

 through which the pupa was quite conspicuous. Another specimen, which 

 began to spin about a week later than the above, changed to pupa about 

 July 29. The first moth {$) emerged on August 17, and the one which 

 pupated on July 29, on Sept. i. In all, four moths were reared, the dates 

 of the emergence of the other two being Sept. 4 and 10. Two larvae were 

 inflated. 



Pupa. — Length 22 mm., width 7 mm., reddish-brown; two specimens 

 dark reddish-brown, two pale reddish-brown, all paler in folds of abdomen. 

 Thorax and abdomen sparsely hairy. Cremaster mahogany brown; bristles 

 capitate, reddish-brown, of varying lengths. Whole pupa slightly pruinose. 



One of the moths was kindly compared by Mr. Wm. BeutenmuUer 

 with the type of .f/^/^r^rt in the American Museum of Natural History, 

 New York.
